  • SURGICAL TREATMENT OF CAROTID STENOSIS

    Objective To summarize cl inical experience of carotid endarterectomy (CEA) in treating severe carotid stenosis. Methods Between October 1998 and January 2010, 215 patients with carotid stenosis were treated with CEA. There were 140 males and 75 females with an average age of 66 years (range, 51-88 years). Transient ischemic attack (TIA) occurred in127 cases, and 31 cases had history of cerebral infarction. All cases were diagnosed definitely by selective angiography and/or CT angiography, and stenosis degree was more than 80%; contralateral carotid artery was also involved in 45 cases. Ninty-six cases were found to have coronary artery stenosis by coronary angiography. CEA and coronary artery bypass grafting were performed simultaneously in 25 cases. Peripheral arterial disease was found in 43 cases and treated at the same time. Results A total of 155 patients were followed up 6-72 months. The cl inical symptom significantly alleviated in 148 cases postoperatively. Two cases had compl ication of cerebral hemorrhage within 1 week postoperatively; one died and the other was resumed after the conservative treatment. One case had hypoglossal nerve injury. Four cases had injuring marginal mandibular branch of the facial nerve, and no special treatment was given. Restenosis was found in 25 patients, and the stenosis degree was less than 25%; moreover, the patients had no TIA. One case died of heart attack at 3 years of follow-up period. Conclusion CEA is an effective and safe method for treating severe carotid stenosis.

  • 单眼一过性黑矇临床研究新进展

    视网膜一过性缺血(TIA)所致的单眼一过性黑矇(TMVL)是短暂性脑缺血发作(TIA)的一种。视网膜动脉本身的部分阻塞、远隔部位的病变如心源性或近端大动脉源性血栓栓子以及眼动 脉或颈动脉狭窄基础上的系统性低血压均可导致TMVL。其中最常见的原因是粥样硬化的颈动脉来源的血栓栓塞导致的视网膜一过性低灌注。与大脑半球TIA相比,TMVL与颈动脉疾病的 关系更为密切。2%~17%的TMVL患者会在发病6个月到3年内发生脑卒中,而且主要为大血管 梗塞。高龄、男性、既往TIA或中风史、间歇性跛行、颈动脉狭窄程度在80%以上以及侧支 循环差是TMVL患者发生脑卒中的高危因素。所有TMVL患者均应早期进行血管性危险因素控制并接受规范抗血小板治疗进行脑血管病二级预防,颈内动脉内膜剥脱手术等血管内治疗可使伴有重度颈动脉狭窄的TMVL患者发生脑卒中的危险明显降低。

  • Clinical Application of 1.5T Magnetic Resonance Arterial Spin Labeling, Diffusion Weighted Imaging and Magnetic Resonance Aangiography in the Diagnosis of Ischemic Cerebrovascular Disease

    目的 探讨磁共振扩散加权成像(DWI)、动脉自旋标记技术(ASL)、磁共振血管成像(MRA)联合应用在缺血性脑血管病诊断中的价值。 方法 对2010年3月-2012年5月经临床和影像学诊断的104例缺血性脑血管病患者,行常规MRI、液体衰减反转恢复序列、DWI及ASL、MRA序列检查,分析DWI、ASL、MRA多种技术显示病变的信号特征、面积大小及与血管关系。 结果 DWI对急性及亚急性脑梗死的检出率为100%,对大、小面积梗死病灶检出率无明显差异;ASL对大、小面积的急性及亚急性脑梗死的检出率有差异,对大面积梗死检出率为100%,对小面积梗死的检出率为70%;DWI和ASL对短暂性脑缺血发作的检出率分别为0%、70%,液体衰减反转恢复序列对短暂性脑缺血发作患者大脑皮层下斑状缺血灶检出最敏感。 结论 DWI和ASL均可用于急性脑梗死的早期诊断,ASL对大、小面积的急性及亚急性脑梗死的检出率有差异,DWI、ASL及MRA联合应用可准确评估缺血半暗区及侧支血管情况,在缺血性脑血管病诊断中有重要价值。

  • EFFECTIVENESS OF SURGICAL TREATMENT OF SYMPTOMATIC TORTUOSITY COMMON CAROTID ARTERY

    ObjectiveTo investigate the safety and effectiveness of vascular reconstruction in patients with symptomatic tortuosity common carotid artery (SCAT). MethodsA retrospective analysis was made on the clinical data of 12 cases of SCAT treated with vascular reconstruction between June 2010 and October 2013. There were 11 females and 1 male with the mean age of 54.8 years (range, 48-62 years). The unilateral common carotid artery was involved in all cases. Imaging examination showed C-shaped tortuosity of 4-8 cm in length (mean, 5.4 cm). The CT, brain CT, ultrasound examinations, or angiography was performed at 1, 3, 6, 9, and 12 months, and annually. ResultsThe surgery success rate was 100% with no perioperative death and serious complications. The mean operation time was 1.98 hours; the mean blood loss was 50 mL; and the mean clamping time was 14.9 minutes. The systolic pressure gradient across the lesion was significantly decreased from (39.58±9.54) mm Hg (1 mm Hg=0.133 kPa) at pre-operation to (5.50±2.39) mm Hg at immediate after operation (t=15.492, P=0.000). No recurrence or stenosis was found at 9 months to 3 years of follow-up. The systolic and diastolic pressures at last follow-up were significantly improved to (132.17±6.24) mm Hg and (82.67±6.51) mm Hg from (152.83±14.80) mm Hg and (94.17±11.30) mm Hg at pre-operation (t=5.751, P=0.000; t=4.976, P=0.000). ConclusionVascular reconstruction in SCAT is recommended for good short- and mid-term effectiveness and relatively low complication and mortality after operation. Moreover, the long-term results still need to be investigated.

  • Transient global amnesia: related factors, imaging features, and prognosis

    ObjectiveTo explore the related factors, responsible lesions, and prognosis of transient global amnesia (TGA).MethodsWe retrospectively collected TGA patients admitted to Zhongshan Hospital Xiamen University between October 1st 2011 and October 31st 2018 and age- and sex-matched health examinees in the Department of Physical Examination in the same period as a control group. We recorded the relevant clinical information of the two groups, such as sex, age, hypertension, diabetes, hyperlipidemia, atrial fibrillation, stroke, migraine, TGA and epilepsy, and the imaging data of the TGA patients. The occurrences of cerebral infarction, cerebral hemorrhage, recurrence of TGA, and myocardial infarction of the two groups were followed up.ResultsA total of 73 TGA patients and 73 age- and sex-matched controls were included. The difference in the history of migraine was statistically significant (χ2=4.000, P=0.038), while there was no significant difference in the history of hypertension, diabetes or other medical history between the two groups (P>0.05). It was found that the responsible focus of TGA was in the hippocampal CA1 region, while the fornix column and the hippocampal CA1 region existed in the same functional loop. The mean follow-up time was (36.0±22.6) months. Sixty-nine TGA patients and 67 healthy controls were followed up. During the follow-up, there was no significant difference in the incidence of cerebral infarction, cerebral hemorrhage, myocardial infarction, or TGA attacks between the two groups (P>0.05). There was no statistically significant difference (P>0.05) in the clinical or follow-up data between the TGA patients with lesion on DWI (n=9) and the ones without lesion on DWI (n=58).ConclusionsMigraine may be a risk factor for TGA. The responsible brain area of TGA may involve a memory loop, including hippocampal CA1 region, fornix column and so on. After the attack of TGA, the long-term prognosis is well.

  • Re-recognition of defibrinogen therapy in prevention and management of artery-venous ischemic stroke

    As a risk factor for vascular diseases and inflammatory diseases, fibrinogen has received more and more attention. Hyperfibrinogenemia is associated with the occurrence, development, and poor outcome of artery-venous ischemic stroke (acute ischemic stroke, transient ischemic attack and cerebral venous thrombosis). Therefore, fibrinogen may be a potential therapeutic target for the prevention and management of artery-venous ischemic stroke. However, there has been controversy regarding the defibrinogen therapy in artery-venous ischemic stroke. Therefore, this paper introduces the efficacy and safety of defibrinogen therapy alone, combined with antiplatelet or combined with anticoagulant in prevention and management of artery-venous ischemic stroke in detail, in order to re-understand the role of defibrinogen therapy in the prevention and management of artery-venous ischemic stroke.
