BACKGROUND Arterial cannulation sites for the surgical repair of type A aortic dissection(AAD)have evolved from right axillary artery(AA)cannulation to bilateral carotid artery(CA)based of femoral artery(FA)cannulation.Postoperative descending aorta remodeling is closely linked to the false lumen area ratio(FLAR),defined as false lumen area/aortic area,as well as to the incidence of renal replacement therapy(RRT).AIM To investigate the effect of the updated arterial cannulation strategy on descending aortic remodeling.METHODS A total of 443 AAD patients who received FA combined cannulation between March 2015 and March 2023 were included in the study.Of these,209 received right AA cannulation and 234 received bilateral CA cannulation.The primary outcome was the change in FLAR,as calculated from computed tomography angiography in three segments of the descending aorta:Thoracic(S1),upper abdominal(S2),and lower abdominal(S3).Secondary outcomes were the incidence of RRT and the serum inflammation response,as observed by the levels of high sensitivity C reaction protein(hs-CRP)and Interleukin-6(IL-6).RESULTS The postoperative/preoperative ratio of FLAR in S2 and S3 was higher in the AA group compared to the CA group(S2:0.80±0.08 vs 0.75±0.07,P<0.001;S3:0.57±0.12 vs 0.50±0.12,P<0.001,respectively).The AA group also had a significantly higher incidence of RRT(19.1%vs 8.5%,P=0.001;odds ratio:2.533,95%CI:1.427-4.493)and higher levels of inflammation cytokines 24 h after the procedure[hr-CRP:117±17 vs 104±15 mg/L;IL-6:129(103,166)vs 83(69,101)pg/mL;both P<0.001]compared to the CA group.CONCLUSION The CA cannulation strategy was associated with better abdominal aorta remodeling after AAD repair compared to AA cannulation,as observed by a greater change in FLAR and lower incidence of RRT. 展开更多

BACKGROUND The utility of D-dimer(DD)as a biomarker for acute aortic dissection(AD)is recognized.Yet,its predictive value for in-hospital mortality remains uncertain and subject to conflicting evidence.AIM To conduct a meta-analysis of AD-related in-hospital mortality(ADIM)with elevated DD levels.METHODS We searched PubMed,Scopus,Embase,and Google Scholar for AD and ADIM literature through May 2022.Heterogeneity was assessed using I2 statistics and effect size(hazard or odds ratio)analysis with random-effects models.Sample size,study type,and patients’mean age were used for subgroup analysis.The significance threshold was P<0.05.RESULTS Thirteen studies(3628 patients)were included in our study.The pooled prevalence of ADIM was 20%(95%CI:15%-25%).Despite comparable demographic characteristics and comorbidities,elevated DD values were associated with higher ADIM risk(unadjusted effect size:1.94,95%CI:1.34-2.8;adjusted effect size:1.12,95%CI:1.05-1.19,P<0.01).Studies involving patients with a mean age of<60 years exhibited an increased mortality risk(effect size:1.43,95%CI:1.23-1.67,P<0.01),whereas no significant difference was observed in studies with a mean age>60 years.Prospective and larger sample size studies(n>250)demonstrated a heightened likelihood of ADIM associated with elevated DD levels(effect size:2.57,95%CI:1.30-5.08,P<0.01 vs effect size:1.05,95%CI:1.00-1.11,P=0.05,respectively).CONCLUSION Our meta-analysis shows elevated DD increases in-hospital mortality risk in AD patients,highlighting the need for larger,prospective studies to improve risk prediction models. 展开更多

BACKGROUND Endovascular repair of aortic dissection is an effective method commonly used in the treatment of Stanford type B aortic dissection.Stent placement during the operation was one-time and could not be repeatedly adjusted during the operation.Therefore,it is of great significance for cardiovascular physicians to fully understand the branch status,position,angle,and other information regarding aortic arch dissection before surgery.AIM To provide more references for clinical cardiovascular physicians to develop treatment plans.METHODS Data from 153 patients who underwent endovascular repair of aortic dissection at our hospital between January 2021 and December 2022 were retrospectively collected.All patients underwent multi-slice spiral computed tomography angiography.Based on distinct post-image processing techniques,the patients were categorized into three groups:Multiplanar reconstruction(MPR)(n=55),volume reconstruction(VR)(n=46),and maximum intensity projection(MIP)(n=52).The detection rate of aortic rupture,accuracy of the DeBakey classification,rotation,and tilt angles of the C-arm during the procedure,dispersion after stent release,and the incidence of late complications were recorded and compared.RESULTS The detection rates of interlayer rupture in the MPR and VR groups were significantly higher than that in the MIP group(P<0.05).The detection rates of De-Bakey subtypesⅠ,Ⅱ,andⅢin the MPR group were higher than those in the MIP group,and the detection rate of typeⅢin the MPR group was significantly higher than that in the VR group(P<0.05).There was no statistically significant difference in the detection rates of typesⅠandⅡcompared to the VR group(P>0.05).The scatter rate of markers and the incidence of complications in the MPR group were significantly lower than those in the VR and MIP groups(P<0.05).CONCLUSION The application of MPR in the endovascular repair of aortic dissection has improved the detection rate of dissection rupture,the accuracy of anatomical classification,and safety. 展开更多

Background: Aortic dissection (AD) is one of the common causes of fatal chest pain in emergency medicine. The main and most common clinical manifestation is pain, with about 90% of patients experiencing sudden persistent, tearing or cutting-like pain in the chest or back. However, there have also been reports of myocardial infarction, heart failure, renal failure, syncope, shock, stroke, paraplegia and other cases. Clinical misdiagnosis is common. Aim: Alert clinicians to aortic dissection with shock and chest tightness as the main clinical presentations. Case Presentation: Report on two cases of aortic dissection with syncope and shock as the main manifestations. Conclusion: Aortic dissection is a highly dangerous cardiovascular emergency with a high mortality rate. In clinical practice, awareness of the clinical manifestations of aortic dissection should be increased. Careful inquiry about medical history, attention to atypical clinical presentations of aortic dissection, thorough physical examination, and comprehensive diagnostic evaluation can improve the success rate of diagnosing aortic dissection. 展开更多

Aortic dissection is the deadliest disease of the cardiovascular system.Type B aortic dissection accounts for 30%-60%of aortic dissections and is mainly treated by endovascular repair of thoracic endovascular aneurysm repair(TEVAR).However,patients are prone to various complications after surgery,with central nervous system injury being the most common,which seriously affects their prognosis and increases the risk of disability and death.Therefore,exploring the risk factors of central nervous system injury after TEVAR can provide a basis for its prevention and control.AIM To investigate the risk factors for central nervous system injury after the repair of a thoracic endovascular aneurysm with type B aortic dissection.METHODS We enrolled 306 patients with type B aortic dissection who underwent TEVAR at our hospital between December 2019 and October 2022.The patients were categorized into injury(n=159)and non-injury(n=147)groups based on central nervous system injury following surgery.The risk factors for central nervous system injury after TEVAR for type B aortic dissection were screened by comparing the two groups.Multivariate logistic regression analysis was performed.RESULTS The Association between age,history of hypertension,blood pH value,surgery,mechanical ventilation,intensive care unit stay,postoperative recovery times on the first day after surgery,and arterial partial pressure of oxygen on the first day after surgery differed substantially(P<0.05).Multivariate logistic regression analysis indicated that age,surgery time,history of hypertension,duration of mechanical ventilation,and intensive care unit stay were independent risk factors for central nervous system injury after TEVAR of type B aortic dissection(P<0.05).CONCLUSION For high-risk patients with central nervous system injury after TEVAR of type B aortic dissection,early intervention measures should be implemented to lower the risk of neurological discomfort following surgery in high-risk patients with central nervous system injury after TEVAR for type B aortic dissection. 展开更多

BACKGROUND Aortic coarctation is a potentially fatal condition that is primarily treated surgically.Despite successful procedures,patients frequently experience postoperative anxiety and depression,which can hinder recovery and worsen outcomes.Pharmacological interventions,such as 5-hydroxytryptamine(5-HT)and norepinephrine reuptake inhibitors,are commonly prescribed;however,their efficacy alone or in combination with non-invasive brain stimulation techniques,such as repetitive transcranial magnetic stimulation(TMS),remains unclear.AIM To assess the effect of medications and TMS on post-aortic surgery anxiety and depression.METHODS We analyzed the outcomes of 151 patients with anxiety and depression who were hospitalized for aortic dissection between January 2020 and September 2022.Using the random number table method,75 and 76 patients were allocated to the normal control and study groups,respectively.All the patients were treated using routine procedures.The control group was administered anti-anxiety and antidepression drugs,whereas the study group was treated with TMS in addition to these medications.The patients in both groups showed improvement after two courses of treatment.The Hamilton Anxiety Scale(HAMA)and the Hamilton Depression Scale(HAMD)were used to assess anxiety and depression,respectively.The serum levels of brain-derived neurotrophic factor(BDNF)and 5-HT were determined using enzyme-linked immunosorbent assay.The Pittsburgh Sleep Quality Index(PSQI)was used to estimate sleep quality,and the Repeatable Battery for the Assessment of Neuropsychological Status(RBANS)was used to assess cognitive function.RESULTS The HAMD and HAMA scores reduced in 2 groups,with the study group achieving a lower level than control(P<0.05).In the control group,43 patients recovered,17 showed improvement,and 15 were deemed invalid.In the study group,52 recovered,20 improved,and four were invalid.The efficacy rate in study group was 94.74%compared to 80.00%in control(P<0.05).The BDNF and 5-HT levels increased in both groups,with higher levels observed in the experimental group(P<0.05).Moreover,the PSQI scores decreased in 2 groups,but were lower in the intervention group than control(P<0.05).The scores of the RBANS items increased,with the study group scoring higher than control(P<0.05).CONCLUSION Combining anti-anxiety and anti-depressive drugs with repetitive TMS after aortic surgery may enhance mood and treatment outcomes,offering a promising clinical approach. 展开更多

Background: Aortic dissection (AD) is a relatively rare but dreadful illness, often accompanied by severe, sharp (or tearing) back pain or anterior chest pain, as well as acute hemodynamic compromise. Painless dissection has also been reported in rare cases and might be misdiagnosed due to its atypical symptoms leading to catastrophic outcomes. Case presentation: The patient was admitted to the hospital due to right limb weakness with speech inability for more than 10 hours. In the routine cardiac ultrasound examination, the avulsion intimal echo was found in the initial segment of the descending aorta. The rupture range was about 11 mm, and the lumen was separated into real and false lumen. Further computed tomography angiography (CTA) examination confirmed the major arterial dissection (De Bakey Type I). Conclusion: We report a case of painless aortic dissection with active carotid artery thrombosis diagnosed by ultrasound and CTA, and to improve the understanding of painless aortic dissection by reviewing relevant domestic and foreign literature. 展开更多

Rationale:Aortic dissection is a life-threatening medical emergency associated with high morbidity and mortality.Preoperative mesenteric malperfusion increases the surgical risk and mortality in patients with type B aortic dissection.For DeBakey type III B patients involving most of the thoracoabdominal aorta,endovascular treatment to improve true lumen perfusion may have limited benefits.Organ reperfusion on-time is crucial.Patient concerns:A 38-year-old man was admitted with sudden severe upper abdominal pain.Emergency CTA of the entire aorta revealed an aortic dissection with an entry tear in the descending aortic arch involving the celiac trunk,superior mesenteric artery,bilateral common iliac arteries and right external iliac artery,with thrombosis in the superior mesenteric artery.Diagnoses:The patient was diagnosed with DeBakey type III aortic dissection with mesenteric artery embolism.Enhanced chest CT showed the entry tear location and involvement of major arteries.Angiography confirmed partial blood flow in the superior mesenteric artery.Interventions:The patient underwent endovascular aortic stent-graft implantation through the left femoral artery,covering the descending aortic arch and sealing the entry tear.Postoperatively,the patient received intensive care,including ventilatory support,CRRT,anti-infection therapy,vasoactive drugs and lumbar cistern drainage.Outcomes:Two weeks postoperatively,the patient developed massive black stools,indicative of intestinal obstruction and necrosis.Exploratory laparotomy revealed ischemic necrosis and rupture of the stomach,small intestine,and colon.Despite surgical efforts,the patient’s condition deteriorated,leading to death from severe infection,acid-base imbalance and multiple organ failure. 展开更多

Background:Here we analyzed mid-term data of thoracic endovascular aneurysm repair(TEVAR)surgery with Castor single-branched stent graft placement for the management of Stanford type B aortic dissection(STBAD)involving the left subclavian artery(LSA).Methods:Between April 2014 and February 2019,32 patients with STBAD involving a Castor single-branched stent graft were included.We analyzed their outcomes,including technical success rate(TSR),surgical duration(SD),presence of ischemia,perioperative complications,LSA patency,and survival rate(SR),using computed tomography angiography and clinical evaluation during mid-term follow-up.Results:The mean patient age was 54.63±12.37 years(range,36–83 years).The TSR was 96.88%(n=31/32).The mean SD was 87.44±10.89 with a mean contrast volume of 125.31±19.30 mL.No neurological complications or deaths occurred during the study period.The patients had a mean hospital stay of 7.84±3.20 days.At a mean follow-up of 68.78±11.26 months,four non-aortic deaths(12.5%)were observed.The LSA patency rate was 100%(n=28/28).There was only one case of type I endoleak immediately after surgery(3.12%)(type I from LSA).However,none of the patients experienced type II endoleaks,and there were no cases of retrograde type A aortic dissection or stent graft-driven new distal entry.Finally,all patients exhibited good LSA patency.Conclusion:TEVAR using a Castor single-branched stent graft may be a highly feasible and efficient procedure for the management of STBAD involving the LSA. 展开更多

Objective Type A acute aortic dissection(TAAAD)is a dangerous and complicated condition with a high death rate before hospital treatment.Patients who are fortunate to receive prompt surgical treatment still face high in-hospital mortality.A series of post-operative complications further affects the prognosis.Post-operative pneumonia(POP)also leads to great morbidity and mortality.This study aimed to identify the prevalence as well as the risk factors for POP in TAAAD patients and offer references for clinical decisions to further improve the prognosis of patients who survived the surgical procedure.Methods The study enrolled 89 TAAAD patients who underwent surgical treatment in Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology,Wuhan,Hubei province,China from December 2020 to July 2021 and analyzed the perioperative data and outcomes of these patients.Logistic regression analyses were used to identify the risk factors for POP.Results In the study,31.5%of patients developed POP.Patients with POP had higher proportions of severe oxygenation damage,pneumothorax,reintubation,tracheotomy,renal replacement therapy,arrhythmia,gastrointestinal bleeding,and longer duration of mechanical ventilation,fever,ICU stay,and length of stay(all with P<0.05).The in-hospital mortality was 2.3%.Smoking,preoperative white blood cells,and intraoperative transfusion were the independent risk factors for POP in TAAAD.Conclusion Patients who underwent TAAAD surgery suffered poorer outcomes when they developed POP.Furthermore,patients with risk factors should be treated with caution. 展开更多

Clinically,it is widely recognized that surgical treatment is the preferred and reliable option for Stanford type A aortic dissection.Stanford type A aortic dissection is an emergent and serious cardiovascular disease characterized with an acute onset,poor prognosis,and high mortality.However,the incidences of postoperative complications are relatively higher due to the complexity of the disease and its intricate procedure.It has been considered that hypoxemia,one of the most common postoperative complications,plays an important role in having a worse clinical prognosis.Therefore,the effective intervention of postoperative hypoxemia is significant for the improved prognosis of patients with Stanford type A aortic dissection. 展开更多

Non-A non-B aortic dissection(AAD)is an infrequently documented condition,comprising of only a small proportion of all AADs.The unique anatomy of the aortic arch and the failure of the existing classifications to adequately define individuals with non-A non-B AAD,have led to an ongoing controversy around the topic.It seems that the clinical progression of acute non-A non-B AAD diverges from the typical type A and B dissections,frequently leading to serious complications and thus mandating early intervention.Currently,the available treatment methods in the surgical armamentarium are conventional open,endovascular techniques and combined hybrid methods.The optimum approach is tailored in every individual case and may be determined by the dissection’s location,extent,the aortic diameter,the associated complications and the patient’s status.The management of non-A non-B dissections still remains challenging and a unanimous consensus defining the gold standard treatment has yet to be reached.In an attempt to provide further insight into this perplexing entity,we performed a minireview of the literature,aiming to elucidate the epidemiology,clinical course and the optimal treatment modality. 展开更多

Introduction:Acute type A aortic dissection(ATAAD)is a catastrophic disease with fatal outcomes.Malperfusion syndrome(MPS)is a serious complication of ATAAD,with an incidence of 20–40%.Many studies have shown that MPS is the main risk factor for poor ATAAD prognosis.However,a risk scoring system for ATAAD based on MPS is lacking.Here,we designed a risk scoring system for ATAAD to assess mortality through quantitative assessment of relevant organ malperfusion and subsequently develop rational treatment strategies.Methods and analysis:This was a prospective observational study.Patients’perioperative clinical data were col-lected to establish a database of ATAAD(N≥3000)and determine whether these patients had malperfusion complica-tions.The Anzhen risk scoring system was established on the basis of organ malperfusion by using a random forest survival model and a logistics model.The better method was then chosen to establish a revised risk scoring system.Ethics and dissemination:This study received ethical approval from the Ethics Committees of Beijing Anzhen Hospital,Capital Medical University(KS2019034-1).Patient consent was waived because biological samples were not collected,and no patient rights were violated.Findings will be disseminated at scientific conferences and in peer-reviewed publications. 展开更多

BACKGROUND Pulmonary sequestrations often lead to serious complications such as infections,tuberculosis,fatal hemoptysis,cardiovascular problems,and even malignant degeneration,but it is rarely documented with medium and large vessel vasculitis,which is likely to result in acute aortic syndromes.CASE SUMMARY A 44-year-old man with a history of acute Stanford type A aortic dissection status post-reconstructive surgery five years ago.The contrast-enhanced computed tomography of the chest at that time had also revealed an intralobar pulmonary sequestration in the left lower lung region,and the angiography also presented perivascular changes with mild mural thickening and wall enhancement,which indicated mild vasculitis.The intralobar pulmonary sequestration in the left lower lung region was long-term unprocessed,which was probably associated with his intermittent chest tightness since no specific medical findings were detected but only positive sputum culture with mycobacterium avium-intracellular complex and Aspergillus.We performed uniportal video-assisted thoracoscopic surgery with wedge resection of the left lower lung.Hypervascularity over the parietal pleura,engorgement of the bronchus due to a moderate amount of mucus,and firm adhesion of the lesion to the thoracic aorta were histopathologically noticed.CONCLUSION We hypothesized that a long-term pulmonary sequestration-related bacterial or fungal infection can result in focal infectious aortitis gradually,which may threateningly aggravate the formation of aortic dissection. 展开更多

BACKGROUND Among the various types of aortic dissection,multichanneled aortic dissection(MCAD)differs from classic double-channeled aortic dissection and involves the formation of an additional false lumen in the aortic wall or the flaps.It is considered a relatively rare condition with high perioperative mortality and morbidity.However,the morphological characteristic and the optimal therapeutic strategy for MCAD has not been fully determined.CASE SUMMARY A 64-year-old man presented to our hospital with severe epigastric abdominal pain radiating to the back that was associated with nausea without emesis.A computed tomography angiogram was performed that revealed a type B aortic dissection with multiple channels extending from the level of the left subclavian artery to the bilateral femoral arteries.We used a medical three-dimensional modeling(3D)modeling system to identify the location and extension of multiple lumens from different angles.It also precisely located the two primary entries leading to the false lumens,which helped us to exclude the two false lumens with one stent-graft.CONCLUSION By applying medical 3D modeling system,we discover the fragility of aortic wall and the collapse of true lumen caused by the multiple false lumens are the two morphological features of MCAD. 展开更多

Myelopathy is a common etiology of acute bilateral limb weakness. While painless acute aortic dissection(AAD)is the most common catastrophic event that can mimic myelopathic manifestations of acute bilateral limb weakness, it is often easily ignoredWe describe a case of painless AAD in a 70-year-old man with a history of hypertension manifesting as acute myelopathy(bilateral limb weakness and loss of all types of sensation)with increased levels of serum myoglobin and D-dimer.Magnetic resonance imaging of the spinal cord revealed a normal thoracic and lumbar spinal cord but a dissection of the thoracic aorta. Computed tomography angiography of the chest and abdominal aorta showed a Stanford type B dissection extending throughout the thoracic aorta and into the abdominal aorta hypomere.The patient died because of a sudden drop in blood pressure during transfer to vascular surgery.The clinical presentation of painless AAD mimics myelopathies.Aortic dissection should be considered in patients presenting with acute bilateral limb weakness.Physical examination of the skin temperature,dorsalis pedis artery,serum D-dimer,and myocardial markers can provide diagnostic clues. 展开更多

He was admitted to our hospital with a strong back pain and diagnosed as an acute type B aortic dissection. On the second day of hospitalization, he developed symptoms of paraplegia, and we considered TEVAR, but we were concerned that TEVAR intervention in the acute phase might worsen the dissection, so we first placed a cerebrospinal drainage (CSFD) device, which resulted in improvement of his symptoms. Thereafter, although his lower limb mobility was fine, he underwent thoracic stent graft aortic repair (TEVAR) in the subacute phase due to worsening ULP. The patient had a good postoperative course and was discharged home unassisted. The initial placement of CSFD was effective in reducing the incidence of paraplegia as a complication of TEVAR and in bringing the timing of TEVAR intervention from the acute phase to the subacute phase. 展开更多

It often occurs in the third trimester of pregnancy and the postpartum period. Most patients have connective tissue diseases such as Marfan syndrome. Thus, the successful repair of a sporadic aortic dissection with maternal and fetal survival in the early second trimester is extremely rare. CASE SUMMARY A 28-year-old woman without Marfan syndrome presented with chest pain at the 16th gestational week. Aortic computed tomographic angiography confirmed an acute type A aortic dissection (TAAD) with aortic arch and descending aorta involvement. Preoperative fetal ultrasound confirmed that the fetus was stable in the uterus. The patient underwent total arch replacement with a frozen elephant trunk using moderate hypothermic circulatory arrest with the fetus in situ. The patient recovered uneventfully and continued to be pregnant after discharge. At the 38^th gestational week, she delivered a healthy female infant by cesarean section. After 2.5 years of follow-up, the patient is uneventful and the child’s development is normal. CONCLUSION A fetus in the second trimester may have a high possibility of survival and healthy growth after aortic arch surgery. 展开更多
