血栓闭塞性脉管炎的腔内治疗

Objective To investigate the value of endovascular surgery for the treatment of thromboangitis obliterans (TAO). Methods Sixteen patients (18 limbs) with thromboangitis obliterans were treated by percutaneous transluminal plasty (PTA). Results Angiographic success on the limb basis was achieved in 15 of 18 treated limbs and the initial technical success rate was 83.34%. Doppler anklebrachial index (ABI) increased from 0.33±0.16 to 0.79±0.23 one week after PTA. The follow-up time was 2～24 months, the average time was 10.84 months. The 3-month, 12-month accumulated primary patency rate were 81.33% and 60. 23% respectively. Conclusion PTA is effective primary invasive treatment for thromboangitis obliterans yielding acceptable primary clinical success with a low complication rate and resulting in moderate long-term clinical patency and a high limb salvage rate.     

髂-颈动脉人工血管旁路术治疗Ⅰ型多发性大动脉炎

多发性大动脉炎是一种病因未明的非特异性肉芽肿性病变,其中Ⅰ型累及弓部血管及其上三大分支,导致动脉的完全闭塞或重度狭窄,从而引起严重的缺血症状,故属于该病中症状最重、治疗最困难的一类[1].

急性肠系膜血管缺血的外科治疗体会

急性肠系膜缺血性疾病是一种发病率低且病死率高的缺血性肠疾病,主要病因为急性肠系膜动脉栓塞、血栓形成,肠系膜血管受压或痉挛和肠系膜静脉血栓形成等.上海复旦大学附属中山医院血管外科自2003年至2007年共收治急性肠系膜缺血患者19例,其中10例行早期血供重建,现报告如下.     

102例Stanford B型主动脉夹层动脉瘤的腔内治疗经验

目的　总结StanfordB型主动脉夹层动脉瘤腔内治疗的经验。方法　术前对患者进行多种影像学检查 ,获得主动脉夹层动脉瘤的解剖学资料。术中在DSA监视下对 1 0 2例StanfordB型主动脉夹层动脉瘤施行了人工血管内支架移植术。术后 1周和术后 1年行螺旋CT检查 ,观察手术疗效以及有无内漏、移位和人工血管内支架塌陷等术后并发症。结果　 1 0 1例 (99 .0 %)临床成功 ,1例(1 . 0 %)于围手术期内死亡。无术后截瘫。 1 8例 (1 7. 6 %)发生内漏。结论　腔内治疗StanfordB型主动脉夹层动脉瘤具有创伤小 ,严重并发症少 ,住院时间短的优势。近期和中期疗效令人满意。

白塞病并发腹主动脉瘤腔内治疗失败一例

患者男,40岁。因“突发上腹剧痛1周,伴一过性高热”入院。入院前10个月于外院行肠系膜上动脉瘤切除,腹主动脉修补术。体检:上腹轻度压痛,未及腹部肿块。CT示可疑肠系膜上动脉瘤破裂。初步诊断为肠系膜上动脉瘤破裂。入院后患者仍诉上腹疼痛,予哌替啶方可缓解。为明确瘤体周围解剖关系,于2004年3月22日行主动脉造影,发现直径约4 cm假性腹主动脉瘤,瘤体位于腹腔于与肾动脉之间,     

卷曲受体蛋白4在高脂血症大鼠种植体周围组织中的早期表达

目的 探讨卷曲受体蛋白4(Frizzled4)在高脂血症大鼠种植体周围组织中早期的表达.方法 48只成年雄性SD大鼠,随机分为实验组和对照组,每组24只.分别喂食高脂饲料和普通饲料8周.均于股骨干骺端植入直径1.5 mm、长2.5 mm的种植体.分别于术后第1天、第3天、第5天和第28天时处死大鼠,获取种植体周围骨组织...     

膜引导组织再生术与硅胶管桥接法修复兔面神经缺损

目的　观察并比较膜引导组织再生术和硅胶管桥接法修复面神经的作用和效果。方法　分别采用膜引导组织再生术和硅胶管桥接法进行兔面神经缺损修复 ,以自体神经移植作为对照 ,通过电生理学和组织学方法 ,观察和比较两种修复方法的效果。结果　上述两种方法都具有修复面神经缺损的作用 ,但其效果存在差别。膜引导组织再生组术后 3个月时 ,两侧面神经干传导速度之差值为 2 .33± 1.2m/s ,而硅橡胶管组为 10 .2 1± 1.5m/s,自体神经移植组为 2 .16± 1.6m/s。结论　膜引导组织再生术修复面神经的效果明显优于硅橡胶管桥接法 ,且具有其它优点 ,有望成为修复面神经的新的有效方法之一
