However, the risk factors and outcomes of acute kidney injury (AKI) in patients after intracoronary stent implantation are still unknown. A retrospective case control study was done in 325 patients who underwent intracoronary stent implantation from January 2010 to March 2011 at the Drum Tower Hospital of Nanjing University School of Medicine. Those were excluded from the study if they had incomplete clinical data. The patients were divided into a normal group and a AKI group according to the standard of post-operation day 7 to identify AKI. The parameters of the patients included: 1) pre-operative ones: age, gender, hypertension, diabetes mellitus, cerebrovascular disease, left ventricular insufficiency, peripheral angiopathy, creatinine, urea nitrogen, estimated glomerular filtration rate (eGFR), hyperuricemia, proteinuria, emergency operation, hydration, medications (ACEI/ARBs, statins); 2) intraoperative ones: dose of contrast media, operative time, hypotension; and 3) postoperative one: hypotension. The parameters were analyzed with univariate analysis and multivariate logistical regression analysis. Of the 325 patients, 51(15.7%) developed AKI. Hospital day and in-hospital mortality were increased significantly in the AKI-group. Univariate analysis showed that age, pre-operative parameters (left ventricular insufficiency, peripheral angiopathy, creatinine, urea nitrogen, estimated glomerular filtration rate, hyperuricemia, proteinuria, hydration), emergency operation, intraoperative parameters (operative time, hypotension) and postoperative hypotension were significantly different. However, multivariate logistic regression analysis revealed that increased age (OR=0.253, 95%CI=0.088-0.727), pre-operative proteinuria (OR=5.351, 95%CI=2.128-13.459), pre-operative left ventricular insufficiency (OR=8.704, 95%CI=3.170-23.898), eGFR〈60 ml/min/1.73 m2 (OR=6.677, 95%CI=1.167-38.193), prolonged operative time, intraoperative hypotension (OR=25.245, 95%CI=1.001-1.034) were independent risk factors ofAKl. AKI is a common complication and associated with ominous outcome following intracoronary stent implantation. Increased age, pre-operative proteinuria, pre-operative left ventricular insufficiency, pre-operative low estimated glomerular filtration rate, prolonged operative time, intraoperative hypotension were the significant risk factors ofAKl.展开更多

Methods: 96 cases of coronary stent implantation were randomly divided into control group and intervention group (experimental group) with each group of 48 cases. The control group received the routine nursing measures after the coronary stent implantation and the experimental group was treated by the comprehensive nursing interventions such as psychological nursing, education of sexual knowledge, playing the full enthusiasm of spouse and appropriate exercise therapy on basis of the routine nursing measures. The two groups were given the questionnaire of brief male sexual function questionnaire (BSFI), Chinese patients with premature ejaculation sexual function score (C-ISFPE) and the international index of erectile function (IIEF-5). The scores of BSFI, C-ISFPE and IIEF-5 were compared between the two groups. Results: There were 29 cases who were satisfied with sexual life on the whole (≤1), 26 cases with different degrees of premature ejaculation symptoms and 21 cases with erectile dysfunctions, which were respectively 27.08%, 30.2% and 21.87% of the total number. The scores of BSFI, C-ISFPE and IIEF-5 inthe experimental group were significantly increased after the interventions (P P IIEF-5 scores in the two groups were significantly different展开更多

Methods We studied 887 patients with 1 045 non-in-stent restenosis lesions in 977 native arteries undergoing DES implantation with IVUS imaging, and compared the dissected stent end to the non-dissected stent end. Results Eighty-two dissections were detected; 51.2% (42/82) involved the proximal and 48.8% (40/82) the distal stent edge. When compared to the non-dissected stent end, residual plaque area [(8.0±4.3) mm2 vs (5.2±3.0) mm2, P【0.01], plaque burden [(52±12)% vs (36±15)%, P【0.01], plaque eccentricity (8.4±5.5 vs 4.0±3.4, P【0.01), and stent edge symmetry (1.17±0.11 vs 1.14±0.08, P=0.02) were larger; plaque burden≥50% was more frequent (62% vs 17%, P【0.01) and calcium deposits (52.5% vs 35.6%, P=0.03) more common; and the lumen/stent area (0.86±0.16 vs 1.02±0.18, P【0.01) was smaller in the stent dissected end. Independent predictors of stent edge dissection were residual plaque eccentricity (OR=1.3, P【0.01) and residual plaque burden≥50% (OR=7.3, P【0.01). Intramural hematomas occurred in 34.1% (28/82) of dissections.Independent predictors of intramural hematomas were plaque eccentricity (OR=1.4, P=0.005), plaque burden≥50% (OR=7.1, P=0.02), and mean lumen diameter to stent diameter ratio (OR=0.37, P=0.04).Concluslon IVUS identified edge dissections after 9.4% of DES implantations. Residual plaque eccentricity and significant plaque burden predicted coronary stent edge dissections. Dissections in less diseased reference segments with an arc of normal vessel wall (greater plaque eccentricity) more often evolved into an intramural hematoma.展开更多

Premature dis- continuation of antiplatelet therapy is associated with a sig- nificant increase in mortality and major adverse cardiac events, in particular, stent thrombosis. Thus, postpone- ment of elective surgery is advocated during the first year after the coronary stent implantation.展开更多

Eight(6%) pte were given aboiximab(ReoPro) or thrombolyais to deal with acute slantthrombosis during the intervention.Immedately after stent implantation,angiographicsuccess(TLMI 3)was obtained in 113(87%)pts,TLMI2 in 14 (11%)and TLMI 1 intwo (2%). Only three pts had residual stonosis(≥50% stenosis)immediately aftertreatment.Except the patients who had coronary artery bypass grafting(CABG)ordied coronary angiographic follow-up was performed in 74(70%)pts at a mean of 6months following the intervention(Table).Conclusion:Rescue stent implantation after failed PTCA in AMI may improve initialangiographic results,but we found a higher restenosis-rate and reintervention-rate inthe long-term run as compared with selectiv stent implantation.展开更多

Serum S1P and Adropin levels were compared between two groups of patients before and after stent implantation, and the inner link of S1P and Adropin levels with vasoactive substance and cytokine levels in patients with restenosis after cerebrovascular stent implantation was further explored.Results: Before stent implantation, the differences in serum levels of S1P, Adropin, vasoactive substances and cytokines were not statistically significant between two groups of patients. After stent implantation, serum S1P and Adropin levels in observation group were lower than those in control group;serum vasoactive substance NO level was lower than that in control group while ET-1, TXB2 and AngⅡ levels were higher than those in control group;serum inflammatory factors TNF-α, IL-6, IL-10 and IL-13 levels were higher than those in control group. Pearson test showed that serum S1P and Adropin levels in patients with restenosis after cerebrovascular stent implantation were directly correlated with the levels of vasoactive substances and cytokines.Conclusion: Serum S1P and Adropin are lowly expressed in patients with restenosis after cerebrovascular stent implantation, and their specific expression are directly correlated with the levels of vasoactive substances and inflammatory cytokines, and can be used as the reliable indexes for early prediction of restenosis after cerebrovascular stent implantation.展开更多

A retrospective analysis was performed on all patients who had Xen45 implantation surgery during a 2-year period(Jun, 2016-Apr, 2018). Of 52 consecutive patients were included with a total of 58 eyes being operated on. QOL was compared both pre-operatively and 6 weeks postoperatively using the GQL-15 questionnaire. There was an overall improvement in GQL-15 summary scores for our patient group. All item scores showed either no change or some degree of improvement. The Xen45 Gel Stent Implant is a promising new intervention which has shown improved QOL scores in our patient group. Further, higher power studies are now needed to compare the Xen45 to trabeculectomy(TE), which is currently the gold standard.展开更多
文摘BACKGROUND Coronary stent implantation is usually used to treat unstable angina to alleviate stenosis or occlusion,promoting blood flow restoration and alleviating symptoms such as myocardial ischemia.And postoperative cardiac rehabilitation is essential for enhancing recovery and prognosis.Nevertheless,conventional rehabilitation lacks specificity,particularly for elderly patients with multiple comorbidities and poor compliance,rendering it less effective.AIM To investigate the effects of systematic cardiac rehabilitation training in elderly patients with unstable angina following coronary stenting intervention.METHODS A retrospective enrollment was conducted comprising fifty-four elderly patients with unstable angina pectoris who underwent systematic cardiac rehabilitation training after receiving coronary intervention as the rehabilitation group,while fifty-three elderly patients who received basic nursing and rehabilitation guidance measures after coronary intervention were assigned to the control group.Differences in Seattle Angina Questionnaire scores,survival quality(SF-36)scores,cardiopulmonary exercise function assessment index,echocardiographic cardiac function index,and adverse cardiovascular events were compared between the two groups.RESULTS After intervention,the rehabilitation group observed greater VO2 Max,maximum metabolic equivalent,eft ventricular ejection fraction,left ventricular end-diastolic diameter and smaller left ventricular end-systolic diameter.And the rehabilitation group observed greater scores of physical activity limitation,stable angina pectoris,treatment satisfaction,and SF-36 score.The incidence of adverse cardiovascular events in the two groups,showed no significant difference.CONCLUSION Systematic cardiac rehabilitation following coronary stenting in elderly patients with unstable angina pectoris can enhance cardiac function recovery,consequently enhancing both quality of life and cardiopulmonary exercise tolerance.

文摘BACKGROUND:To investigate the most appropriate dual antiplatelet therapy(DAPT)duration for patients with acute coronary syndrome(ACS)after drug-eluting stent(DES)implantation in the largest cardiovascular center of China.METHODS:We enrolled 5,187 consecutive patients with ACS who received DES from January to December 2013.Patients were divided into four groups based on DAPT duration:standard DAPT group(11-13 months,n=1,568)and prolonged DAPT groups(13-18 months[n=308],18-24 months[n=2,125],and>24 months[n=1,186]).Baseline characteristics and 5-year clinical outcomes were recorded.RESULTS:Baseline characteristics were similar across the four groups.Among the four groups,those with prolonged DAPT(18-24 months)had the lowest incidence of major adverse cardiovascular and cerebrovascular events(MACCEs)(14.1%vs.11.7%vs.9.6%vs.24.2%,P<0.001),all-cause death(4.8%vs.3.9%vs.2.1%vs.2.6%,P<0.001),cardiac death(3.1%vs.2.6%vs.1.4%vs.1.9%,P=0.004),and myocardial infarction(MI)(3.8%vs.4.2%vs.2.5%vs.5.8%,P<0.001).The incidence of bleeding was not different among the four groups(9.9%vs.9.4%vs.11.0%vs.9.4%,P=0.449).Cox multivariable analysis showed that prolonged DAPT(18-24 months)was an independent protective factor for MACCEs(hazard ratio[HR]0.802,95%confidence interval[CI]0.729-0.882,P<0.001),all-cause death(HR 0.660,95%CI 0.547-0.795,P<0.001),cardiac death(HR 0.663,95%CI 0.526-0.835,P<0.001),MI(HR 0.796,95%CI 0.662-0.957,P=0.015),and target vessel revascularization(HR 0.867,95%CI 0.755-0.996,P=0.044).Subgroup analysis for high bleeding risk showed that prolonged DAPT remained an independent protective factor for all-cause death and MACCEs.CONCLUSION:For patients with ACS after DES,appropriately prolonging the DAPT duration may be associated with a reduced risk of adverse ischemic events without increasing the bleeding risk.
文摘Acute kidney injury following percutaneous coronary intervention (PCI) is associated with a worse outcome. However, the risk factors and outcomes of acute kidney injury (AKI) in patients after intracoronary stent implantation are still unknown. A retrospective case control study was done in 325 patients who underwent intracoronary stent implantation from January 2010 to March 2011 at the Drum Tower Hospital of Nanjing University School of Medicine. Those were excluded from the study if they had incomplete clinical data. The patients were divided into a normal group and a AKI group according to the standard of post-operation day 7 to identify AKI. The parameters of the patients included: 1) pre-operative ones: age, gender, hypertension, diabetes mellitus, cerebrovascular disease, left ventricular insufficiency, peripheral angiopathy, creatinine, urea nitrogen, estimated glomerular filtration rate (eGFR), hyperuricemia, proteinuria, emergency operation, hydration, medications (ACEI/ARBs, statins); 2) intraoperative ones: dose of contrast media, operative time, hypotension; and 3) postoperative one: hypotension. The parameters were analyzed with univariate analysis and multivariate logistical regression analysis. Of the 325 patients, 51(15.7%) developed AKI. Hospital day and in-hospital mortality were increased significantly in the AKI-group. Univariate analysis showed that age, pre-operative parameters (left ventricular insufficiency, peripheral angiopathy, creatinine, urea nitrogen, estimated glomerular filtration rate, hyperuricemia, proteinuria, hydration), emergency operation, intraoperative parameters (operative time, hypotension) and postoperative hypotension were significantly different. However, multivariate logistic regression analysis revealed that increased age (OR=0.253, 95%CI=0.088-0.727), pre-operative proteinuria (OR=5.351, 95%CI=2.128-13.459), pre-operative left ventricular insufficiency (OR=8.704, 95%CI=3.170-23.898), eGFR〈60 ml/min/1.73 m2 (OR=6.677, 95%CI=1.167-38.193), prolonged operative time, intraoperative hypotension (OR=25.245, 95%CI=1.001-1.034) were independent risk factors ofAKl. AKI is a common complication and associated with ominous outcome following intracoronary stent implantation. Increased age, pre-operative proteinuria, pre-operative left ventricular insufficiency, pre-operative low estimated glomerular filtration rate, prolonged operative time, intraoperative hypotension were the significant risk factors ofAKl.
文摘Objective: To study the effects of comprehensive nursing interventions on sexual functions in young and middle-aged patients with coronary stent implantation. Methods: 96 cases of coronary stent implantation were randomly divided into control group and intervention group (experimental group) with each group of 48 cases. The control group received the routine nursing measures after the coronary stent implantation and the experimental group was treated by the comprehensive nursing interventions such as psychological nursing, education of sexual knowledge, playing the full enthusiasm of spouse and appropriate exercise therapy on basis of the routine nursing measures. The two groups were given the questionnaire of brief male sexual function questionnaire (BSFI), Chinese patients with premature ejaculation sexual function score (C-ISFPE) and the international index of erectile function (IIEF-5). The scores of BSFI, C-ISFPE and IIEF-5 were compared between the two groups. Results: There were 29 cases who were satisfied with sexual life on the whole (≤1), 26 cases with different degrees of premature ejaculation symptoms and 21 cases with erectile dysfunctions, which were respectively 27.08%, 30.2% and 21.87% of the total number. The scores of BSFI, C-ISFPE and IIEF-5 inthe experimental group were significantly increased after the interventions (P P IIEF-5 scores in the two groups were significantly different
文摘Vertebral artery dissection is a rare pathology that can cause ischemic stroke in young people.Cervical massage,especially improper pulling manipulation,is a cause of vertebral artery dissection.We present a case of 32-year old woman who developed acute multiple posterior circulation ischemic cerebral infarctions as a result of left vertebral artery V4 segment dissection after receiving neck massage.She underwent emergency vertebral artery stent implantation at the site of the dissection.Symptoms were relieved the day after treatment.The patient recovered without adverse complications or endovascular restenosis in the following year.

文摘Biodegradable stents made of magnesium(Mg)and its alloys have been developed to minimize persistent inflammation or in-stent restenosis,which are the main problems for permanent stents.However,their rapid corrosion behavior under physiological conditions leads to poor vascular compatibility and premature structural failure,which remains an important unsolved clinical problem.Herein,we demonstrate a new strategy for solving this problem by combining poly(ether imide)(PEI)coating and subsequent tantalum(Ta)ion implantation.The PEI coating covers the whole surface of the Mg stent uniformly via a spray coating technique and provides Mg with superior corrosion resistance and stable sirolimus-carrying ability.Ta ion implantation is conducted by a sputtering-based plasma immersion ion implantation technique only onto the luminal surface of the PEI-coated Mg stent.Its extremely short processing time(<30 s)permits preservation of the PEI coating’s corrosion protection ability and sirolimus loading characteristics.In addition,a Ta-implanted skin layer that forms on the topmost surface of the PEI coating plays an effective role in not only preventing a rapid release of sirolimus from the surface but also improving the PEI coating’s surface hydrophilicity.Based on in vitro cellular response and blood compatibility tests,Ta ion implantation leads to the improvement of endothelial cell adhesion/proliferation and suppression of platelet adhesion/activation regardless of sirolimus loading.These results indicate that the combination of PEI coating and Ta ion implantation has significant innovative potential to provide excellent vascular compatibility and prevent in-stent restenosis and thrombosis.
文摘Objective We used intravascular ultrasound (IVUS) to assess incidence, predictors, morphology, and angiographic findings of edge dissections and intramural hematomas after drug-eluting stent (DES) implantation. Methods We studied 887 patients with 1 045 non-in-stent restenosis lesions in 977 native arteries undergoing DES implantation with IVUS imaging, and compared the dissected stent end to the non-dissected stent end. Results Eighty-two dissections were detected; 51.2% (42/82) involved the proximal and 48.8% (40/82) the distal stent edge. When compared to the non-dissected stent end, residual plaque area [(8.0±4.3) mm2 vs (5.2±3.0) mm2, P【0.01], plaque burden [(52±12)% vs (36±15)%, P【0.01], plaque eccentricity (8.4±5.5 vs 4.0±3.4, P【0.01), and stent edge symmetry (1.17±0.11 vs 1.14±0.08, P=0.02) were larger; plaque burden≥50% was more frequent (62% vs 17%, P【0.01) and calcium deposits (52.5% vs 35.6%, P=0.03) more common; and the lumen/stent area (0.86±0.16 vs 1.02±0.18, P【0.01) was smaller in the stent dissected end. Independent predictors of stent edge dissection were residual plaque eccentricity (OR=1.3, P【0.01) and residual plaque burden≥50% (OR=7.3, P【0.01). Intramural hematomas occurred in 34.1% (28/82) of dissections.Independent predictors of intramural hematomas were plaque eccentricity (OR=1.4, P=0.005), plaque burden≥50% (OR=7.1, P=0.02), and mean lumen diameter to stent diameter ratio (OR=0.37, P=0.04).Concluslon IVUS identified edge dissections after 9.4% of DES implantations. Residual plaque eccentricity and significant plaque burden predicted coronary stent edge dissections. Dissections in less diseased reference segments with an arc of normal vessel wall (greater plaque eccentricity) more often evolved into an intramural hematoma.
文摘It has been reported that up to 12% of patients underwent non-cardiac surgery or invasive procedures within the first year after the coronary stent implantation. Premature dis- continuation of antiplatelet therapy is associated with a sig- nificant increase in mortality and major adverse cardiac events, in particular, stent thrombosis. Thus, postpone- ment of elective surgery is advocated during the first year after the coronary stent implantation.
文摘The data of 24 cases(18men,6women) with AMI treated with directPTCA and intracoronary stant implantation were analyzed.The infart-related vessels were 13 LADs,4LCXs,7KCAs:The successful rate washigh(95.8%).The mean stenoses before and after performation were 95.6±5.4%,8.3±0.2%.18 stems were implanted in 16 cases.Lesscomplication happened during the procedure.There was a higher TIMI Ⅲflow patency rate in PTCA and intracoronary stent implantation than indrug thrombolysis (92% vs 40%).Stent implantation had a significanteffect on myocardial reperfution by enhancing the successful rate ofPTCA and reducing the stenosis significantly.
文摘Objective To evaluate the clinical efficacy of Palmaz-Sctatz(P-S)stent,and sum up the experience of P-S stent implantation.Methods The P-S stent were implanted in 79 patients with 85 coronarylesions.According abscences of in hospital death.emergency coronary arterybypass grafting(CABG),Q wave myocardial infarctina(MI)or repeatintervention,measured the primary successfui rate of stent implantation atpostoperatively and the bail out rate of acute coronary closure afterpercutaneous transluminal coronary angioplasty(PTCA).Clinical follow upin 74 of 82 lesions of successful stent implantation was obteined at 3-6month after operation,the restnotic rate was measured by quantitativecoronary angiography.The restenosis was defined as】50% diameterstenosis at follow up.Results In 79 patients with 85 coronary lesion.82 were successfulimplanted.the successful rate was 96%.The Q wave MI 2 patients andemergency CABG 1 patient in 3 patients of unsuccessful stent implantation,and that have not death and repeat interveation.The 28 patients weredelivered in 31 patients with acute coronary closure after PTCA.The bailout rate was 90%.12 have restenosis in 82 lesions of follow up at 3-6month after stent implantation,the restenotic rate was 16%.Conclusion The successful rate of P-S stent implantation was high.andthe occur rete of major adverse events was lower than other stents.Thebail out rate was high in acute coronnry closure after PTCA.The restenotierate at 3-6 month after stunt implantation has lower than other stents.Butthe P-S stent yes not suitable for medium winding blood vessel and was
文摘Stent implantation in acute myocardial infarction(AMI)has been shown to improvethe acute angiographic outcomes.So far few data on long-term angiographic follow-up are avallble.Methods:We studied 130 consecutive patients(mean age 58±11,24 women)betweenOctober 1993 and October 1997,in whom coronary stonts were implanted afterunsuccessful percutaneous transluminal coronary angioplasty (PTCA)in AMI.Quantitative coronary angiography(QCA)was performed and residual stenosis wasmesuremesured for all patients immediately and for 74 patients at a mean of 6 months afterthat procedure.Results:The infarct related artery was the left anterior dascending in 60(46%)pts,the circumflex in 15(12%)and the right coronary artery in 55(42%).At baseline,72(55%)pts had a totally occluded artery(TLMI0)and 11(8%)TIMI 1 flow. Eight(6%) pte were given aboiximab(ReoPro) or thrombolyais to deal with acute slantthrombosis during the intervention.Immedately after stent implantation,angiographicsuccess(TLMI 3)was obtained in 113(87%)pts,TLMI2 in 14 (11%)and TLMI 1 intwo (2%). Only three pts had residual stonosis(≥50% stenosis)immediately aftertreatment.Except the patients who had coronary artery bypass grafting(CABG)ordied coronary angiographic follow-up was performed in 74(70%)pts at a mean of 6months following the intervention(Table).Conclusion:Rescue stent implantation after failed PTCA in AMI may improve initialangiographic results,but we found a higher restenosis-rate and reintervention-rate inthe long-term run as compared with selectiv stent implantation.
文摘Wikter-i and multilink Coronary stent has beenimplanted in 38 lesions in 31 patients.Theindications for stent implantation were 21 elective,11 chronic total occlusion.4 threatened closure and2 suboptimal.Vessel distribution was 21 LAD,8 RCA,9LCX,Successful stent implabation was achievied inall of pstients,Lession length was 15.3±8.6mm.Theaverage final balloon size after stent placement was4.5mm(range 3.5-6.0mm) end minimal luminal diameterwithin the stent was 3.75mm(range 3.0-4.0mm).Maximum inflation pressure was 14±2 atmospheres.AWiktor-i stent used in 21 lesions and multilinkstent in 17 lesion.All of patients were treated withonly antiplatelet therapy after successful stentimplantation,There was no stent thrombosis orvascular complication.Mean elapsed time from stentplacement to femoral sheath rsmoval was 5.6 hours(range 4-7hours).Patients were discharged from thehospital within 1 week of stent placement,allreceiving aspirin 300mg per day,end ticlopidine250ms twice a day,In three months of clinic follow-up,no patients experienced stent throebosJs.After astent is deployed,routine high pressure ballooninflation is performed within the stent to ensureuniform circumferential expansion and optimalopposition of the stent to the vessel wall.Whenoptimal stent expansion was achieved,there was nostent thrombosis despite the absence of anti-coagulation in all of patients.
文摘The clinical benefit of coronary-artery steating performed inconjunction with coronary angioplasty is limited by the risk of thromboticocclusion of the stant as well as hemorrhagic and vascular complications ofintensive anticoaguistion.We analysed complications of three patientscaused by improper antithrombotic therapy after coronary artery stanting.Method and Result:Case 1,male,52 years old.The diagnosis is old myocardial infarction(OMI),unstable angina pectoris(UAP).Gianturco-Roubin stent was successfullyimplanted into right coronary artery(RCA).Balloon angioplasty wasperformed in left circumflex artary(LCX).Angiography showed optimal resultafter the procedure.The patient bad acute inferior myocardial infarction onthe same day,and died from ventricular fibrillation on the third day afterthe stenting.Case 2,male,53 years old.The diagnosis is UAP.Two Gianturco-RoubinStents were implanted into left anterior descending artery(LAD)and RCArespectively,angioplasty was done in LCX On the tenth day atfer theprocedure,bloody urine happened.By reducing warfarin dosage be bloodyurine disappeared.Case 3.female.71 years old.the diagnosis is acute anterior myocardialinfarction,UAP.Multilink stent was implanted into LAD,balloon dilatationwas done in RCA.On the day of the stenting,groin regional bleeding andshock happendod.Afterwards.acute anterior,Supralataral MI and acute heartfailure happended.Finally the patient was discharged.DiscussionRecently the success rate of the stent implantation reach at 95%.However,the main complications are stent thrombosis as well as bleeding,vascular access complicalions caused by intensive antithrombotic agent.Inthese three patients,the death of the first case is due to acute stentthrombosis resulted from insufficient antithrombotic therapy.The bloodyurine of second case is caused by too much intensive anticoagulation.Thecomplications of the third case is due to too much intensive antithrombosisat beginning and insufficient antithrombosis at latter.The antithrombosisafter stenting should be monitored by ACT,CT or PTT The antipisteletherapy can largely reduce the stent thrombosis and the incidence of theleeding.
文摘Purpose: To analyze the application of percutaneous transluminal angioplasty and stenting in acute deep venous thrombosis of lower extremities. Methods: 70 patients were divided into two groups according to the presence or absence of percutaneous transluminal angioplasty and stenting. Results: The mean circumferential diameter difference between the affected limbs and the healthy limbs and the knees at 15 cm was statistically significant. The cure rate and effective rate of the research group were higher than those of the control group (P<0.05). Conclusion: Percutaneous transluminal angioplasty and stenting are of high value in acute lower extremity deep venous thrombosis.
文摘Objective:To explore the predictive value of serum S1P and Adropin levels for the restenosis after cerebrovascular stent implantation and their relationship with vasoactive substances and cytokines.Methods:A total of 109 patients with cerebral infarction who accepted cerebrovascular stent implantation in our hospital between July 2012 and May 2016 were selected, their treatment outcome were reviewed, 35 patients with restenosis after cerebrovascular stent implantation were selected as observation group, and 74 patients without restenosis after cerebrovascular stent implantation were selected as control group. Serum S1P and Adropin levels were compared between two groups of patients before and after stent implantation, and the inner link of S1P and Adropin levels with vasoactive substance and cytokine levels in patients with restenosis after cerebrovascular stent implantation was further explored.Results: Before stent implantation, the differences in serum levels of S1P, Adropin, vasoactive substances and cytokines were not statistically significant between two groups of patients. After stent implantation, serum S1P and Adropin levels in observation group were lower than those in control group;serum vasoactive substance NO level was lower than that in control group while ET-1, TXB2 and AngⅡ levels were higher than those in control group;serum inflammatory factors TNF-α, IL-6, IL-10 and IL-13 levels were higher than those in control group. Pearson test showed that serum S1P and Adropin levels in patients with restenosis after cerebrovascular stent implantation were directly correlated with the levels of vasoactive substances and cytokines.Conclusion: Serum S1P and Adropin are lowly expressed in patients with restenosis after cerebrovascular stent implantation, and their specific expression are directly correlated with the levels of vasoactive substances and inflammatory cytokines, and can be used as the reliable indexes for early prediction of restenosis after cerebrovascular stent implantation.

文摘Objective To investigate the characteristics of neointimal hyperplasia (NIH) in patients with in-stent restenosis (ISR) over 5 years post-drug-eluting stent(DES) implantation based on optical coherence tomography (OCT).Methods In this cross-sectional study,patients with DES-ISR who underwent OCT examination at PLA General Hospital between March 2010 and March 2022 were retrospectively included.
文摘Our aim was to report quality of life(QOL) outcomes following Xen45 Gel Stent implantation surgery in patients suffering with primary open angle glaucoma(POAG). A retrospective analysis was performed on all patients who had Xen45 implantation surgery during a 2-year period(Jun, 2016-Apr, 2018). Of 52 consecutive patients were included with a total of 58 eyes being operated on. QOL was compared both pre-operatively and 6 weeks postoperatively using the GQL-15 questionnaire. There was an overall improvement in GQL-15 summary scores for our patient group. All item scores showed either no change or some degree of improvement. The Xen45 Gel Stent Implant is a promising new intervention which has shown improved QOL scores in our patient group. Further, higher power studies are now needed to compare the Xen45 to trabeculectomy(TE), which is currently the gold standard.
