Objective To investigate the safety and feasibility of carotid artery stenting (CAS) and evaluate its clinical outcomes. Methods From July 1998 to December 2003, 30 consecutive patients with 32 lesions underwent extracranial CAS procedures. Thirteen patients had a history of stroke or TIAs, 22 were hypertensive, 11 were diabetic and 8 had history of MI. Neurological assessment, Carotid duplex ultrasound, carotid and intracranial angiography were done before CAS in all patients. All the cases were done percutanously from femoral arteries and stenting was applied in all procedures. Carotid duplex ultrasound, cardiac and neurological elevation were performed post procedure. Results 30 patients (26 male and 4 female) underwent a total of 32 CAS procedures. Total 32 self-expandable stents and 1 tubular stent were implanted in all the cases. Direct stenting technique was applied in 9 cases. The other 21 procedures were performed with distal filtration supporting devices. The device can not be delivered due to tortuous target vessel in one case (success rate 95%) and CAS success rate was 97%. The particles were found in all filter baskets. Four patients underwent coronary artery bypass grafting 1 month later post CAS without perioperative neurological and cardiac events. One patient had contralateral cerebral hemorrhage during CAS and died three days later. Another patient died three days after CAS due to acute pulmonary edema. No restenosis was found by means of carotid duplex ultrasound during the follow-up (3-60 months) study. Conclusion CAS is safe and feasible in preventing ischemic stroke. This new alternative has satisfied clinical outcomes in managing cardiac and neurological ischemic diseases. Operative embolic complication can be potentially prevented by neurological protective device.

Objectives To investigate the recurrence risk factors and the protective factors of aortic dissection (AD) DeBakey type Ⅲ. Methods 43 patients with AD DeBakey type Ⅲ who were in Guangdong General Hospital from May 2014 to September 2014, were enrolled as the case group, while 27 volunteers exclude AD as the control group. Blood chemistries and other information obtained immediately after admissions , χ2 test or T test was used for univariate analysis of independent samples. Multivariate Logistic regression analysis was used to screen patients with recurrence risk factors or protective factors. Results The prevalence of hypertension (93.02%vs. 18.52%, P = 0.000) and proportion of smokers (34.88% vs. 11.11%, P = 0.027) were significantly higher in case group than control group. Logistic regression analysis showed that hypertension (OR=5.148, 95%CI= [2.209~13.058], P=0.001) and albumin level (OR=0.709, 95%CI = [0.541~0.929], P=0.013) were significantly associated with recurrence of aortic dissection DeBakey type Ⅲ. Conclusion Hypertension is an independent risk factor for recurrence of aortic dissection DeBakey type Ⅲ, and albumin level is a protective factor.
