  • 主动脉弓部夹层动脉瘤手术治疗

    目的 总结通过人工血管旁路术延长锚定距离后,腔内隔绝术(endovascular graft exclusion,EVGE)治疗主动脉弓部夹层动脉瘤的疗效。 方法 2005 年9 月- 2007 年9 月,采用血管旁路术后二期行EVGE 治疗主动脉弓部夹层动脉瘤10 例。男9 例,女1 例;年龄33 ~ 55 岁,平均38 岁。合并高血压病8 例,尿毒症1 例。DSA 示近端破口位于左颈总动脉与左锁骨下动脉之间4 例;破口距左锁骨下动脉开口lt; 1.5 cm 且左椎动脉为优势动脉6 例,合并无名动脉瘤1 例,升主动脉及主动脉弓部壁内血肿1 例。 结果 除1 例患者由于真腔闭塞未能行EVGE 治疗外,9 例均顺利完成EVGE 治疗。术后即刻造影示Ⅰ型内漏、Ⅱ型内漏(左锁骨下动脉未结扎所致)各1 例,分别于治疗后1、3 个月经计算机X 线断层扫描血管造影术证实内漏消失。8 例破口封堵良好,1 例并发降主动脉周围血肿而失访。8 例获随访,随访时间12 ~ 36 个月,降主动脉假腔内血栓形成。 结论 人工血管旁路术延长锚定距离,不仅可扩大EVGE 的适应证,还能降低Ⅰ型内漏。

  • Intermediate Stage Report about Change of Deep Venous Valve Function after Superficial Vein Surgery of Lower Extremity

    Objective To evaluate improved effect for deep venous valve function after superficial vein surgery of lower extremity in the intermediate stage. Methods Totally 43 patients (55 limbs) with varicose veins of lower extremity were enrolled to accept surgical management of vein systems in our department from March 2006 to October 2006. All patients were respectively followed up after 6 months and 4 years about the changes of deep venous valve function with color Doppler ultrasonography. Results Thirty-nine patients’ deep venous valve function kept well up to now, and there was no significant difference between the two results. Four patients without proximal saphenous vein ligation recurred, and there was reflux in deep venous. Conclusion Endovenous laser treatment and ablation of varicose veins of lower extremity with deep venous insufficiency could improve deep venous valve function effectively. Proximal great saphenous vein ligation is important for successful operation.

  • Treatment of Thromboangitis Obliterans by Embolectomy

    Objective To explore the clinical experience on treatment of thromboangitis obliterans (TAO) by embolectomy. Methods Fourteen of 121 patients with TAO treated in our hospital from March 2000 to March 2010 were included in this study. Total 14 limbs consisted of 2 upper extremities and 12 lower extremities. Among these cases, 8 cases underwent embolectomy and 6 cases received embolectomy combined the stem cell transplantation. Results Of 14 cases of TAO patients, 11 cases were successfully treated by surgery and 3 cases failed. After successful operation, patient’s pain disappeared and anklebrachial index improved obviously. Seven patients treated successfully by surgery were followed up from 5 months to 8.5 years (mean 4 years), in whom the intermittent claudication and rest pain disappeared in 4 cases, and disease deteriorated in 2 cases who always smoked, and one case had intermittent claudication who stopped smoking. For 3 cases patients failed to operation, one lost followup, one had to receive a below knee amputation due to keep smoking after operation, and one case who stopped smoking underwent alleviative symptoms for 3 years. Conclusion Embolectomy is a safe and effective technique for treating TAO.
