Then, transradial coronary catheterization became a popular & default technique due to less vascular access site complications and bleeding as compared to femoral route. Distal puncture of the radial artery through the anatomical snuff box access, however, has recently been shown potential benefit, like comfort to patients and operators, as well as maintenance of blood flow through the superficial palmar arch, in case of radial artery occlusion. Our aim was to evaluate the safety and feasibility of this new approach. Methods: A cross-sectional observational prospective study of patients underwent invasive diagnostic or therapeutic coronary procedures through the distal trans-radial access and traditional radial access. The primary endpoints were to access difficulties and in-hospital access-site related complications. Results: In 2 months, 190 patients underwent coronary procedures, of which 82 (43%) were selected in both distal transradial & traditional radial group. In 2(2.4%) & 3 (3.6%) cases, distal radial & traditional radial access cannulation was unsuccessful respectively (p >0.05). The mean age was 57.7 ± 10 & 57.2 ± 10 years in successful distal transradial & traditional radial cases respectively. There were no any major vascular complications in distal transradial group while there were 2 vascular complications in traditional radial group (p > 0.05). Conclusions: Distal transradial access is feasible and safe in selected cases, when performed by experienced operators. Larger case series and randomized trials are required to determine its efficacy in reducing vascular complications when comparing to the traditional technique.展开更多

Methods The data of 83 cases who accepted transradial coronary angiography (CAG) and transradial percutaneous coronary intervention (PCI) in our department were summarized. The success rates, proximal coronary complications, peripheral vascular complications, severe vagal reflex, mean operation time (MOT), mean recumbent time (MRT), mean hospital-staying time (MHT) were analyzed. The data were compared with that of 420 cases of transfemoral coronary procedures (TFCP) in the same period. Results Success rates and proximal coronary complications were similar in both groups. Severe vagal reflexes were less in TRCP group than in TFCP group. MOT was longer in TRCP group. MRT and MHT were shorter in TRCP group. 12(14.5%) radial artery spasm, 3(3.6%) radial artery obstruction, 1 sudden respiratory arrest caused by jugular hematoma were observed in TRCP group. Conclusions The efficacy and safety of TRCP are definite. TRCP is more economical. For the purpose of properly evaluate the peripheral vascular complications of TRCP, it is necessary to pay special attention to radial artery occlusion, radial artery stenosis, and jugular hematoma.展开更多

In this study, we designed to investigate the incidence of RAS during transradial procedures in Chinese, find out the independent predictors through multiple regression, and analyze the clinical effect of RAS during follow-up. Methods Patients arranged to receive transradial coronary angiography and intervention were consecutively enrolled. The incidence of RAS was recorded. Univariate analysis was performed to find out the influence factors of RAS, and logistic regression analysis was performed to find out the independent predictors of RAS. The patients were asked to return 1 month later for the assessment of the radial access.Results The incidence of RAS was 7.8% (112/1427) in all the patients received transradial procedure. Univariate analysis indicates that young (P=0.038), female (P=0.026), small diameter of radial artery (P 〈0.001), diabetes (P=0.026), smoking (P=0.019), moderate or severe pain during radial artery cannulation (P〈0.001), unsuccessful access at first attempt (P=0.002), big sheath (P=0.004), number of catheters (〉3) (P=0.048), rapid baseline heart rate (P=0.032) and long operation time (P=0.021) were associated with RAS. Logistic regression showed that female (OR=1.745, 95% CI: 1.148-3.846, P=0.024), small radial artery diameter (OR=4.028, 95%CI: 1.264-12.196, P=0.008), diabetes (OR= 2.148, 95%CI: 1.579-7.458, P=0.019) and unsuccessful access at first attempt (OR=1.468, 95%CI: 1.212-2.591, P=0.032) were independent predictors of RAS. Follow-up at (28±7) days after the procedure showed that, compared with non-spasm patients, the RAS patients had higher portion of pain (11.8% vs. 6.2%, P=0.043). The occurrences of hematoma (7.3% vs. 5.6%, P=0.518) and radial artery occlusion (3.6% vs. 2.6%, P=0.534) were similar. Conclusions The incidence of RAS during transradial coronary procedure was 7.8%. Logistic regression analysis showed that female, small radial artery diameter, diabetes and unsuccessful access at first attempt were the independent predictors of RAS.展开更多

But the great limitation of radial artery approach and main failure cause of transradial coronary intervention is smaller size and more variations of a radial artery approach. The aim of the study is to explore the features and variations of a radial artery approach in southern Chinese populations and their clinical significance in percutaneous coronary intervention. Methods A total of 1400 patients who underwent scheduled first time transradial coronary angiography between July 2007 and September 2010 were enrolled. Radial arteriography was performed in all patients to detect the anatomical variations of this vessel. All patients' radial and ulnar artery inner diameters were measured using a computer assisted quantification method. A detailed patient history was recorded. Multivariate Logistic regression analysis was performed to evaluate the predictive value of variables (including age, gender, ethnicity, height, weight, body mass index, smoking, diabetes, hypertension and dyslipidemia) in arterial tortuosities and variations of this vessel. Results In southern Chinese populations, there were no significant differences in the diameters of the forearm arteries: the mean radial artery inner diameter was (3.04±0.43) mm in ethnic Han Chinese and (3.05±0.42) mm in ethnic Zhuang Chinese, P 〉0.05), the mean ulnar artery inner diameter was (3.03±0.38) mm in Han Chinese and (3.05±0.36) mm in Zhuang Chinese, P 〉0.05). It was estimated that the inner diameter of the radial artery was not smaller than a 6F Cordis sheath in 86.1% of male patients and in 57.0% of female patients, and not smaller than a 7F Cordis sheath in 59.3% of male patients and 24.9% of female patients. The factors found to positively affect the size of the radial artery were sex (bj=0.309, P 〈0.01), weight (bj=0.103, P 〈0.01 ), and diabetes mellitus (bj=-0.088, P 〈0.01) was found to negatively affect radial artery size. Arterial tortuosities occurred in 12.1% of patients and arterial variations in 4.1%. The incidence of tortuosities and variations included radial artery tortuosity (3.6%), high origin of radial artery (1.7%), radial artery loop (0.6%), double radial artery (0.1%), brachial artery tortuosity (0.4%), double brachial artery (0.1%), subclavian artery tortuosity (5.4%), small subclavian artery (0.4%), right retro-esophageal subclavian artery (0.6%), brachiocephalic trunk tortuosity (2.8%), small brachiocephalic artery (0.1%), and brachiocephalic artery anomaly (0.4%). For people in Guangxi province, tortuosities of the subclavian artery and radial artery are the most common among the vascular tortuosities of the radial artery approach. The overall rate of transradial procedural success was 96.1%. Procedural failure was more common in patients with anomalous radial artery approach than in patients with normal radial artery approach (22.8% vs. 1.8%, P=0.000). According to multivariate Logistic regression analysis, age (OR=2.695, 95% CI 2.232-3.253, P=0.000), female gender (OR=5.127, 95% CI 3.000-8.762, P=0.000), height (OR=0.612, 95% CI 0.465-0.807, P=0.000), body mass index (OR=2.377, 95% CI 1.834-3.082, P=0.000), hypertension (OR=1.668, 95% CI 1.132-2,458, P=0.010), hyperlipidemia (OR=1.273, 95% CI 1.425-2.049, P=0.034) and smoking (OR=5.750, 95% CI 3.636-9.093, P=0.000), were independently associated with arterial tortuosities of the radial artery approach. Female gender was independently associated with arterial variations of the radial artery approach (OR=3.613, 95% CI 3.208-7.826, P=0.000). Conclusions The diameters of the radial and ulnar arteries between the Han people and the Zhuang people in southern Chinese populations are similar. In a transradial operation, the most southern Chinese populations, the use of a 6F sheath and guiding catheter is safe, and using a 7F sheath and guiding catheter is feasible in some selected patients. Radial arterial tortuosities and variations in southern Chinese populations are relatively common and are a significant cause of the failure of transradial coronary procedure. Old age, female gender, short stature, high body mass index,hypertension, hyperlipidemia and smoking, were independently associated with an increased risk of arterial tortuosity. In addition, female gender was an independent predictor of arterial variations.展开更多

Whether the addition of intravenous tirofiban during this procedure produces further benefit has not been clarified in ST segment elevation myocardial infarction (STEMI) patients. We evaluated this on STEMI patients who underwent primary PCI (p-PCI) via transradial artery approach. Methods Consecutive patients were randomized into tirofiban group (n=-72) or placebo group (n=-78). Angiographic analysis included initial and final thrombolysis in myocardial infarction (TIMI) flow grade (TFG), corrected TIMI frame count (CTFC) and TIMI myocardial perfusion grade (TMPG) of the thrombotic vessel. Platelet aggregation rate (PAR), creatine phosphokinase (CPK), CPK isoenzyme MB (CPK-MB) and troponin I levels were measured and TIMI definitions were used to assess bleeding complications. Left ventricular performance parameters were investigated with equilibrium radionuclide ventriculography. Major adverse cardiac events (MACE) were followed up for 6 months. Results The cases of TFG 0 and 1 before PCI, TFG 0 when first crossing of guide wire were less, and the cases of TFG 3 after PCI was more in tirofiban group than those in placebo group. The final CTFC was fewer and the incidence of no reflow phenomenon was lower, as well the percentage of final TFG 3 was higher in tirofiban group than those in placebo group (all P 〈0.05). Mean peak CPK-MB was significantly lower, while the left ventricular performance parameters 1 week after PCI were much more improved in tirofiban group than those in the placebo group. PAR was significantly decreased shortly after tirofiban infusion. The incidence of 6-month MACE in tirofiban group was obviously lower than that in the placebo group. No statistical difference was noted between the two groups with regard to bleeding complications. Conclusions Intravenous tirofiban infusion, in addition to aspirin and clopidogrel in STEMI patients with p-PCI via transradial artery access, can quickly inhibit platelet aggregation, loosen occlusive thrombus, improve myocardial reperfusion and reduce incidence of MACE with few complications of vessel access and bleeding.展开更多

文摘Background Aspirin and clopidogrel can improve myocardial reperfusion and alleviate myocardial injury during percutaneous coronary intervention (PCI). Whether the addition of intravenous tirofiban during this procedure produces further benefit has not been clarified in ST segment elevation myocardial infarction (STEMI) patients. We evaluated this on STEMI patients who underwent primary PCI (p-PCI) via transradial artery approach. Methods Consecutive patients were randomized into tirofiban group (n=-72) or placebo group (n=-78). Angiographic analysis included initial and final thrombolysis in myocardial infarction (TIMI) flow grade (TFG), corrected TIMI frame count (CTFC) and TIMI myocardial perfusion grade (TMPG) of the thrombotic vessel. Platelet aggregation rate (PAR), creatine phosphokinase (CPK), CPK isoenzyme MB (CPK-MB) and troponin I levels were measured and TIMI definitions were used to assess bleeding complications. Left ventricular performance parameters were investigated with equilibrium radionuclide ventriculography. Major adverse cardiac events (MACE) were followed up for 6 months. Results The cases of TFG 0 and 1 before PCI, TFG 0 when first crossing of guide wire were less, and the cases of TFG 3 after PCI was more in tirofiban group than those in placebo group. The final CTFC was fewer and the incidence of no reflow phenomenon was lower, as well the percentage of final TFG 3 was higher in tirofiban group than those in placebo group (all P 〈0.05). Mean peak CPK-MB was significantly lower, while the left ventricular performance parameters 1 week after PCI were much more improved in tirofiban group than those in the placebo group. PAR was significantly decreased shortly after tirofiban infusion. The incidence of 6-month MACE in tirofiban group was obviously lower than that in the placebo group. No statistical difference was noted between the two groups with regard to bleeding complications. Conclusions Intravenous tirofiban infusion, in addition to aspirin and clopidogrel in STEMI patients with p-PCI via transradial artery access, can quickly inhibit platelet aggregation, loosen occlusive thrombus, improve myocardial reperfusion and reduce incidence of MACE with few complications of vessel access and bleeding.
文摘Background:The risk of radial artery occlusion (RAO) needs particular attention in transradial intervention (TRI).Therefore,reducing vascular occlusion has an important clinical significance.The aim of this study was to determine the appropriate puncture site during TRI through comparing the occurrence of RAO between the different puncture sites to reduce the occurrence of RAO after TRI.Methods:We prospectively assessed the occurrence of RAO in 606 consecutive patients undergoing TRI.Artery occlusion was evaluated with Doppler ultrasound in 2 days and 1 year after the intervention.Risk factors for RAO were evaluated using a multivariate model analysis.Results:Of the 606 patients,the RAO occurred in 56 patients.Compared with TRI at 2-5 cm away from the radius styloid process,the odds ratio (OR) for occlusion risk at 0 cm and 1 cm were 9.65 (P =0.033) and 8.90 (P =0.040),respectively.The RAO occurred in the ratio of the arterial diameter to the sheath diameter ≤1 (OR =2.45,P =0.004).Conclusion:Distal puncture sites (0-1 cm away from the radius styloid process) can lead to a higher rate of RAO.
