There was no enough evidence to support the view that endovascular treatment could alternate the endarterectomy to be a standard treatment of carotid stenosis. A recent Cochrane systematic review found no difference in major outcomes between endovascular treatment and surgery. The randomised trials provided data to show that the main advantage of endovascular treatment for carotid artery stenosis was the avoidance of minor complications such as cranial nerve palsy and wound haematoma of surgery. Longer term follow also showed no difference in the rate of stroke during follow-up, but the confidence intervals were very wide allowing the possibility of a substantial difference in risk and benefits of the two treatments. There was no difference in avoidance of stroke between carotid stenting using protection devices and surgery, and the protection devices could cause additional complications.
【摘要】 目的 探讨血尿酸水平、颈动脉斑块与冠心病之间的关系。 方法 收集2006年1月-2009年12月拟诊为冠心病的住院患者280例,冠状动脉造影检查冠状动脉狭窄程度gt;50%的194例为冠心病组,冠状动脉无狭窄或狭窄程度lt;50%的86例为对照组;冠心病组又分为单支、双支、多支病变亚组。分别测定冠心病组与对照组颈总动脉与颈动脉分叉处内膜中层厚度(IMT)、等级评分、Crouse积分、血尿酸浓度。结果 与对照组相比,冠心病组颈总动脉与颈动脉分叉处IMT、等级评分、Crouse积分、血尿酸浓度均高于对照组,差异有统计学意义。在冠心病组,随病变分支的增多,颈动脉超声检查指标与血尿酸随之升高(Plt;0.05或0.01)。 结论 颈动脉IMT、等级评分、Crouse积分、血尿酸浓度与冠心病相关,是冠心病的独立危险因素。【Abstract】 Objective To investigate the relationships between serum uric acid levels, carotid artery plaque and coronary heart disease (CHD). Methods 194 patients with CHD and 86 nonCHD patients were selected through coronary angiography in patients with essential hypertension. CHD group was divided into three subgroups including a single branch, doublebranch and multivessel disease. Intimamedia thickness (IMT) of carotid artery and carotid bifurcation, grade score, Crouse score, serum uric acid concentrations were detected in patients with coronary heart disease and control group. Results IMT of carotid artery and carotid bifurcation, grade score,crouse score, serum uric acid concentrations were higher in CHD group than that in control group, and the difference was statistically significant. In the CHD group, ultrasound parameters of carotid artery and serum uric acid increased with the increase in branch lesions (Plt;005 or 001). Conclusions Carotid IMT, grade score, Crouse score, serum uric acid concentration relate to coronary heart disease, which is an independent risk factor for coronary heart disease, respectively.
Objective To investigate the clinical characteristics and mechanisms of ocular manifestations related to carotid artery stenosis. Methods The general clinic data and related ocular manifestations in 124 patients with carotid artery stenosis were retrospectively. Results In the 124 patients, 36 (29%) had ocular manifestations, and 28 (22. 6 %) complained the ocular discomfort as the first symptom. Among the 36 patients, 31 patients (86.1%) had been disclosed unilateral or double stenosis of internal carotid artery by carotid Doppler ultrasound examination, and the result of digital subtract angiography revealed middle and severe degree of internal carotid artery stenosis in 8 and 23 patients respectively. There was no statistic difference of incidence of ocular manifestations between 67 patients of severe internal carotid artery stenosis and 34 patients with middle one（chi;２test,P =0.266 2，P＞0.05). The ocular manifestations included amaurosis fugax (52.8%),acute decline or loss of the visual ability and defect of visual fields (36.1%), binocular diplopia (13.9%), ptosis (13.9%), and persistent high intraocular pressure(2.8%) one patient might had several ocular manifestations simultaneously. In 36 patients, central retinal artery occlusion had been diagnosed in 4, venous stasis retinopathy in 1,central or branch retinal vein occlusion in 6, neovascular glaucoma in 1, and anterior ischemic opticneuropathy in 2. One patient with double occlusion of internal carotid artery didnrsquo;t have any ocular manifestation. Conclusion Carotid artery stenosis, especially internal carotid artery may lead to acute or chronic ocular ischemic lesions, and the occurrence of ocular manifestations in chronic ocular ischemic lesions relates to compensa tion of collateral circulation；patients with ocular ischemic lesions are recomm end to undergo a routine carotid artery examination.

Objective To investigate the experience of selective embolization combined with intraoperative internal carotid artery shunt for surgical treatment of carotid body tumor （CBT）. Methods The data of 21 patients （22 sides） with CBT who underwent surgical resection from January 2002 to July 2012 in our hospital were retrospectively reviewed. The all patients’ conditions were fully assessmented and all patients were performed the carotid arteriography and superselective embolization treatment for the blood supply of tumor by with microcatheter on 2-3 days before operation，and then intraoperative internal carotid artery shunt and resection of carotid body tumors were performed. Results Surgical procedures were successfully performeded in all 21 patients （22 sides）. Among them， 16 patients （17 sides） were taken carotid body tumor resected， 5 patients were taken carotid body tumor resected and internal carotid artery reconstruction （autogenous long saphenous vein were used in 3 patients， vascular prosthesis were used in 2 patients）. The postoperative complications were found in 5 patients after anesthesia recovery， which included crooked tongue in 3 cases and facial numbness in 2 cases， and they were cured in 3 months. There were no cerebral infarction， hemiplegia， and death cases. All 21 patients were followed-up for a period from 2 months to 9 years（average 57 months）， there was no tumor recurred. Conclusions Surgical resection is the first choice for treatment of carotid body tumor. The application of selective embolization and intraoperative internal carotid artery shunt for surgical treatment of carotid body tumor in complicated Shamblin Ⅲ stage is safe and effective.
