膝下动脉缺血性病变:外科手术和腔内治疗的疗效对比
膝下动脉缺血性病变多发生于糖尿病下肢动脉闭塞症和下肢血栓性脉管炎,它的治疗主要包括下肢远端动脉旁路移植、膝下动脉腔内治疗和自体干细胞移植三种技术.自体干细胞移植目前尚未在全国大规模地推广和普及,因此,前两种治疗方法仍是此类疾病的主要选择.下肢远端动脉旁路移植作为一种常规技术,已有几十年的历史;而血管腔内治疗是近20年发展起来的技术.两种治疗的疗效对比情况如何?这是血管外科医师和患者都关心的问题.

Objective To study the endovascular treatment of artery rupture caused by injury on which surgery was impossibly performed. Methods All 76 patients underwent selective angiography to make accurate diagnosis. Endovascular occlusion of the target artery with a balloon catheter was accomplished and surgical vessel repair followed in 13 cases. Under the condition that the blood supply of the remote limb on which the artery rupture was detected remained normal, the injured artery was obstructed completely with either detachable balloon or coil in 63 cases.Results No complication, disability, or death was found in any case.Conclusions Occlusion of the blood flow of the target vessel with balloon catheter is an easy, effective and safe preoperational approach for patients who fail to be treated perfectly with direct surgery.

颅内微小动脉瘤血管内介入治疗研究进展
一直以来,颅内微小动脉瘤(大横径≤3 mm)的血管内介入治疗存在很大争议.由于微小动脉瘤腔小、壁薄,介入治疗存在很大的技术难度和风险.近年来,随着栓塞材料及栓塞技术的进步,血管内介入技术在颅内微小动脉瘤治疗中的应用被广泛接受,并逐渐成为一种安全、有效的治疗方法[1-4].本文对颅内微小动脉瘤的血管内介入治疗进展进行综述.
