联合股-股动脉旁路移植术的单臂支架腔内修复腹主动脉瘤的经验

目的探讨联合股-股动脉旁路移植术(cross-femoral bypass grafting,CFBG)的单臂支架型血管(aortouniiliac,AUI)腔内修复腹主动脉瘤(endovascular aneurysm repair,EVAR)的疗效。方法1997年5月~2007年2月,对8例因髂动脉的特殊解剖条件无法应用分叉支架型血管的腹主动脉瘤采用联合CFBG的AUI支架型血管进行EVAR治疗。术后观察内漏、缺血并发症、股股旁路血管的通畅性以及下肢血供情况等。结果围手术期无死亡,1例因急性心肌梗死于术后15个月死亡。3例原发性内漏分别于术后1、3、6个月自愈。8例平均随访24个月(3~72个月),旁路均通畅,1例于术后1年吻合口轻微狭窄但无下肢缺血症状。结论因髂动脉解剖条件复杂不能应用分叉支架型血管的腹主动脉瘤采用联合CFBG的AUI支架型血管进行EVAR是安全、有效的。     

Aneurysm Resection and Vascular Reconstruction for True Aneurysm at the Initial Segment of Splenic Artery

The aneurysms at the initial segment of splenic artery are rare. This paper aimed to investigate the methods to treat the true aneurysm at the initial segment of splenic artery by aneurysmectomy plus vascular reconstruction. Retrospectively reviewed were 11 cases of true aneurysm at the initial segment of splenic artery who were treated in our hospital from January 2000 to June 2013. All cases were diagnosed by color ultrasonography, computer tomography(CT) and angiography. Upon resection of the aneurysm, the auto-vein transplantation was performed in situ between the hepatic artery and the distal part of the splenic artery in 1 case; the artificial vessel bypass was done between the infra-renal aorta and distal portion of the splenic artery in 7 cases; the splenectomy was done in 2 cases; the splenectomy in combination with ligation of multiple small aneurysms were performed in 1 case. All cases were cured and discharged from the hospital 10–14 days after operation. A 1–14 year follow-up showed that 9 cases survived, and 2 cases died, including 1 case who died of acute myocardial infarction 2 years after aorta-splenic artery bypass operation and 1 case who died of acute cerebral hemorrhage 5 years after aneurysm resection and the splenectomy. Among 6 cases receiving aorta-splenic artery bypass, 1 gradually developed stenosis at anatomosed site, which eventually progressed to complete occlusion 2 years to 6 years after operation, without suffering from splenic infarction because the spleen was supplied by the short gastric vessel and its collaterals. The other 5 cases receiving aorta-splenic artery bypass and 1 case undergoing autologous vascular transplantation did not develop stricture or pseudoaneurysm at the stoma. Our study showed that the aneurysmectomy plus vascular reconstruction is a better treatment for aneurysm at the initial segment of splenic artery.     

开窗支架型血管治疗近肾腹主动脉瘤的初步临床结果

目的回顾性分析开窗支架型血管治疗近肾腹主动脉瘤（AAA）的初步结果。方法4例合并严重疾病无法行开放手术的近肾AAA患者,根据术前CT数据定制个体化开窗支架型血管。于全身麻醉下置人此支架型血管并置入肾动脉支架。结果术后即时造影示各分支血管血流通畅,支架形态良好,两例有少量近端I型内漏。术后3个月复查4例患者支架形态正常,两例I型内漏均消失,但另一名患者出现Ⅱ型内漏。结论应用个体化开窗支架型血管治疗近肾AAA近期效果良好。     

蛛网膜下腔出血应用脑脊液置换术的疗效

蛛网膜下腔出血(SAH)是神经内、外科的危重病之一,常见的病因为颅内动脉瘤和脑血管畸形,约占SAH的70%,前者较后者多见.其他原因有动脉硬化、脑底异常血管网征、颅内肿瘤卒中、血液病、动脉炎、脑炎、脑膜炎及抗凝治疗的并发症,但均晨少见.     

职业院校德育实效性问题探究

德育在学校教育中居于首要地位,它直接关系到人才培养的质量,因此受到各级各类学校的重视。但目前学校德育的实效性不高也是一个不争的事实,职业院校受＂技术教育观＂片面追求＂应用＂与＂技能训练＂及生源基本素质和能力较低的影响,德育低效问题更加突出。职业院校要想摆脱当前培养出来的学生＂有知识缺修养、有技能缺思想、有技术缺能力＂的困境,重新获得发展的活力,就必须探索产生困境的原因,纠正对德育的错误认识,并针对性地解决当前存在的问题。

高风险患者腹主动脉瘤手术与腔内治疗效果的比较

目的 比较高风险患者腹主动脉瘤(abdominal aortic aneurysm,AAA)手术治疗(opensurgical repair,OSR)与腔内治疗(endovascular aneurysm repair,EVAR)的效果,探讨高风险患者AAA治疗方式的选择.方法 利用(customized probability index,CPI)危险评分方法[1]筛选出我院1998年至2008年高风险患者55例,比较OSR组(20例)与EVAR组(35例)围手术期及术后近期结果.结果 OSR组随访率100%,平均随访6年3个月.EVAR组随访率94%,平均随访5年10个月.(1)手术时间高风险患者EVAR组(3.1±0.6)h短于OSR组[(4.9±0.9)h(P<0.05)];(2)EVAR组术中出血、ICU时间和住院时间均短于OSR组(P<0.01);(3)围手术期死亡率EVAR组(2.86%)明显低于OSR组(15.00%);(4)术后并发症发生率EVAR组(17%)明显低于OSR组(40%);(5)EVAR组术后并发症主要为内漏(8.57%);(6)OSR组并发症主要为心脏相关性疾病(25%).结论 EVAR对于高风险患者AAA的治疗可以更少的导致围手术期心血管事件的发生,降低围手术期的死亡率和并发症发生率.CPI可以相对准确评估血管手术围手术期死亡率和并发症的发生率,可用于指导围手术期的治疗策略.
