METHODS: Twenty patients underwent 21 CEAs at the Zhongshan Hospital between May 1993 and June 2000. They were 19 men and 1 woman, with a mean age of 64 +/- 9 years. Seven patients were performed for stroke, 11 for transient ischaemic attacks (TIAs) and 2 for asymptomatic disease. Duplex scan was the primary tool of evaluation prior to surgery. Perioperative digital subtraction angiography and magnetic resonance angiography were done for 19 and 18 patients, respectively. The percentage of stenosis was calculated using NASCET criteria. Of the 21 lesions operated, 19 had a stenosis of 70% or greater, 2 had ulcerative lesions with a stenosis ranging from 60% to 69%. All CEAs were performed under cervical block anaesthesia with selective intraoperative shunting and patch angioplasty. The patients were followed up regularly with duplex scan surveillance. RESULTS: There was no mortality or stroke during 30 days postoperatively. A TIA occurred in one patient and cranial nerve injury in 2 patients perioperatively. All patients were followed up for a mean interval of 31 +/- 20 months (range: 1 - 63 months). The 2-year survival rate and risk of stroke were 92.3% and 0%, respectively, and the 5-year survival rate and risk of stroke were 79.1% and 12.5%, respectively. Two asymptomatic recurrent stenoses ranging from 50% to 60% were detected on follow-up duplex scan. CONCLUSIONS: For the patients in this study, CEA is associated with an acceptable perioperative outcome as well as a satisfactory long-term beneficial effect in stroke prevention.展开更多

Methods A total of 3,237 participants aged ≥ 40 years were recruited from Jidong community in 2013-2014. Participants were divided into five quintile groups based on their serum ALP levels. Carotid atherosclerosis was assessed using ultrasound. Abnormal IMT, carotid plaque, and ECAS were defined as IMT > 0.9 mm, IMT > 1.5 mm, and ≥ 50% stenosis in at least one extracranial carotid artery, respectively. Results Common carotid IMT values and the prevalence of carotid plaque increased across serum ALP quintiles. Higher ALP quintiles were correlated with an increased risk of abnormal IMT [fourth quintile: odds ratio(OR) 1.78, 95% confidence interval(CI) 1.13-2.82, P = 0.0135;fifth quintile: OR = 1.82, 95% CI: 1.15-2.87, P = 0.0110] and ECAS compared to the lowest quintile(fifth quintile: OR = 1.47, 95% CI: 1.09-1.97, P = 0.0106). The association between ALP and prevalence of carotid plaque became insignificant after adjustment for confounders. Conclusion Serum ALP levels were independently associated with abnormal common carotid IMT and ECAS. These conclusions need to be further corroborated in future prospective cohort studies.展开更多

文摘目的:探讨血清胱抑素C(Cystatin c,CysC)水平与短暂性脑缺血发作(Transient ischemic attack,TIA)患者颈内动脉狭窄的相关性.方法:纳入2019年1月至2022年6月我院收治的170例TIA患者为研究对象,根据脑血管造影检查结果评估颈动脉狭窄发生情况;并将颈动脉狭窄程度分为轻度狭窄组(n=38)、中度狭窄组(n=40)和重度狭窄组(n=41).收集所有患者基线资料,并在入院后测定患者实验室指标,重点分析血清CysC水平与TIA患者颈内动脉狭窄的相关性.结果:170例TIA患者中有119例患者发生颈动脉狭窄,发生率为70.00%,其中轻度狭窄患者38例,中度狭窄患者40例,重度狭窄患者41例;四组TIA患者性别、吸烟史、饮酒史、年龄、体重指数(Body Mass Index,BMI)、入院时美国国立卫生研究院卒中量表(National Institutes of Health Stroke Scale,NIHSS)评分、入院时收缩压(Systolic Blood Pressure,SBP)及入院时舒张压(Diastolic blood pressure,DBP)、血清总胆固醇(Cholesterol,CHO)水平比较,差异无统计学意义(P>0.05);重度狭窄组患者血清CysC水平均高于中度狭窄组及轻度狭窄组,三组间比较,差异有统计学意义(P<0.05).经Logistic回归分析显示,血清CysC水平升高是TIA患者颈动脉狭窄程度加重的风险因子(OR>1,P<0.05).结论:血清CysC水平与TIA患者颈内动脉狭窄密切相关,血清CysC水平升高会加重TIA患者颈内动脉狭窄程度.
