目的:了解注射吸毒致假性股动脉瘤的特点及外科治疗的疗效.方法:2000年1月-2008年6月间收治30例假性股动脉瘤破裂患者.手术治疗26例,4例拒绝.瘤体切除、瘤腔清创后,其中,行股动脉直接修补3例,人工血管片修补8例,应用四氟乙烯(ePTFE) 人工血管移植10例,股动脉结扎5例.结果:拒绝手术4例患者全部死亡.25例肢体均存活,足背动脉搏动恢复.术后伤口出血再次手术3例,其中截肢1例.随访3个月～4年,股动脉结扎中1例肢体间歇性跛行.结论:彻底清创、血管修补或移植、控制感染是治疗注射吸毒致假性股动脉瘤的有效方法;直接行股动脉结扎在条件困难情况下是可选择的术式.     

毒品注射致假性动脉瘤并感染的外科治疗

目的探讨毒品注射所致假性动脉瘤伴感染的外科治疗处理方法。方法回顾性分析因毒品注射所致假性动脉瘤患者27例共28条肢体的临床资料。1例为肱动脉假性动脉瘤,余26例为股动脉假性动脉瘤。2例未行手术,23例24条肢体行瘤体切除、瘤腔清创及人工血管移植术,2例行动脉破口修补术。结果死亡2例;4例出现移植物感染,3例行移植物取出并结扎动脉,1例行扩创引流加换药后保肢成功;其余手术患者术后均无肢体血供障碍,3个月后16例行彩超检查示人工血管通畅。结论彻底清创、血管重建、控制感染是治疗吸毒所致假性动脉瘤的有效方法,移植物感染通过结扎动脉或建立通畅的引流能避免截肢。     

注射毒品致感染性假性股动脉瘤破裂19例外科治疗

目的 探讨注射毒品致感染性假性股动脉瘤破裂的外科治疗方法.方法 回顾分析19例注射毒品致感染性假性股动脉瘤破裂患者的临床资料,术前应用彩超或下肢血管造影诊断;8例采用人工血管行旁路髂外动脉和股浅动脉端端吻合术,11例行单纯瘤体两端股动脉结扎术.结果 全部病例手术成功,无继发肢体坏死;血管移植者术后复查彩色多普勒超声显示移植血管通畅.结论 瘤体切除+人工血管移植仍是治疗注射毒品所致假性股动脉瘤的理想方案;但在无条件行血管移植时,瘤体切除+股动脉结扎术是治疗的有效方法之一;不提倡行破裂瘤体修补术.     

注射毒品致股动脉感染性假性动脉瘤的外科治疗

目的：探讨注射毒品致股动脉感染性假性动脉瘤的外科治疗。方法：回顾性分析因注射毒品致股动脉感染性假性动脉瘤患者63例的临床资料。结果：假性动脉瘤破裂52例,住院期间再次或多次出血者26例。行髂外动脉—股浅动脉旁路带环人工血管重建术49例,行髂外动脉或股动脉结扎术14例。围手术期无死亡。1例住院期间出现移植物感染,5例随诊期间出现移植物感染,感染的移植物取出后同时行髂外动脉或股动脉结扎保肢成功。1例行股动脉结扎患者术后出现肢体坏死行大腿截肢。其余手术患者均恢复良好。36例复诊彩超检查示人工血管通畅。结论：尽早外科手术是抢救因注射毒品致感染性假性动脉瘤患者生命的唯一途径;彻底清创引流、髂外动脉—股浅动脉旁路带环人工血管重建以及控制感染是治疗的有效方法;在感染严重且局部条件无法重建血管的情况下,结扎髂外动脉或股动脉也是一种救治患者的可行选择。

Infected femoral pseudoaneurysms in intravenous drug abusers: a decade of experience from a Singapore tertiary centre

INTRODUCTIONA pseudoaneurysm (or false aneurysm) is a haematoma that communicates with an artery through a disruption in the arterial wall. The femoral artery is the most common injection site among drug users, and infected femoral pseudoaneurysms are the most common vascular complications.METHODSA retrospective review of medical records of intravenous drug abusers (IVDAs) who presented with infected femoral pseudoaneurysms from January 2006 to December 2016 was carried out. Patients who had pseudoaneurysms due to other aetiologies or trauma were excluded.RESULTSA total of 27 patients with infected femoral pseudoaneurysms were identified. The majority were male (92.6%) and of Malay ethnicity (55.6%). Median age was 50 (range 31–62) years. Commonly abused drugs were buprenorphine (or Subutex; 59.3%) and midazolam (or Dormicum; 51.9%). Groin pain and swelling (100.0%), fever (66.7%) and presence of a pulsatile mass (51.9%) were the most common presenting symptoms. Diagnosis was confirmed via computed tomography angiography in all patients. 25 patients underwent upfront arterial ligation with debridement, among whom three patients required concurrent surgical revascularisation. Only two patients underwent ultrasonography-guided thrombin injection – one eventually required surgery and the other was lost to follow-up. Postoperative complications included wound infection (42.3%), bleeding (11.5%) and necrotising fasciitis eventually resulting in limb loss (3.8%). There were no associated mortalities.CONCLUSIONInfected pseudoaneurysms in IVDAs pose a unique challenge to vascular surgeons. We found that simple ligation and debridement was a safe and effective option for such patients.     

Management of infected femoral pseudoaneurysms in intravenous drug abusers: a review of 57 cases

BACKGROUND: The present study was carried out to evaluate the clinical characteristics and surgical methods used for the management of infected femoral pseudoaneurysms secondary to illegal drug injections. METHODS: Fifty seven consecutive patients who presented with infected pseudoaneurysm of the lower limb and were admitted to the emergency department of Sina Hospital during a 5-year period were enrolled in this study. Surgical methods performed consisted of vein angioplasty, simple ligation of femoral artery, and emergent or delayed revascularization. RESULTS: All participating patients were males with a mean age of 36.7 years. Three (5.3%) and two (3.5%) patients underwent primary repair and emergent vascular bypass, respectively; whereas delayed revascularization was performed in only eight (14%) cases. Forty four (77.2%) patients achieved a normal lifestyle without any vascular bypass. Early critical ischemia and late claudication was reported in two (3.5%) and eight (14%) patients, respectively. Other complications such as amputation and mortality were rarely reported. CONCLUSIONS: In our study, simple ligation of the external iliac or femoral artery was the most frequent management method for treating infected femoral pseudoaneurysms. Simple ligation of the external iliac or femoral artery seems to be a safe procedure in drug abusers presenting with infected femoral pseudoaneurysms.     

动脉穿刺致假性动脉瘤原因及治疗对策探讨

目的探讨动脉直接穿刺致假性动脉瘤的发生原因及治疗效果。方法分析本院介入诊疗中心2009年10月～2010年5月525例直接穿刺动脉导致的4例假性动脉瘤患者的临床及治疗情况。结果 4例均治愈,其中3例徒手压迫,1例行外科修补。结论股动脉直接穿刺术后患者发生股动脉假性动脉瘤与多种因素有关,治疗上可以采用直接压迫、外科修补、瘤腔内注射凝血酶的方法来治疗。     

Revascularization for Iliac-femoral Artery Pseudoaneurysm with Greater Saphenous Vein

Objective To investigate the role of revascularization procedures with autologous greater saphenous vein in surgical management of iliac-femoral artery pseudoaneurysm in parenteral drug abusers. Methods Twenty-one patients with iliac-femoral artery pseudoaneurysm caused by parenteral drug abuse from 2004 to 2007 were enrolled. Among them,15 patients were male and 6 were female; their average age was 31.3 years. The size of pseudoaneurysms ranged from 3.0 cm to 7.5 cm. Common femoral artery and distal external iliac artery were often involved. We performed arterial reconstruction on these patients with autologous greater saphenous vein as a graft after excising iliac-femoral artery pseudoaneurysm through a single curved inguinal incision. All patients were followed up,and the complications were recorded. Results The surgical procedures were finished without intraoperative mortality or perioperative complications. All patients were free of claudication symptoms after the surgery except one case with preoperative popliteal artery stenosis. One case of infection and wound tissue fistula was found later. One case had inguinal incisional hematoma and another complained of numbness in thigh skin. Conclusions The use of autologous greater saphenous venous grafts for arterial reconstruction after pseudoaneurysm excision in drug abusers is safe and effective. This technique offers more advantages than arterial ligation alone without revascularization. An optimal greater saphenous venous graft is a prerequisite for revascularization.     

注射海洛因致假性股动脉瘤的治疗(附6例报告)

目的：探讨注射毒品海洛因致假性股动脉瘤的手术治疗方法。方法：对6例注射海洛英致假性股动脉瘤的患者的临床资料进行总结分析。其中3例患者行假性动脉瘤近端和远端结扎术，2例行血管旁路移植术，1例患者行动脉成形术。结果：术后全部患者均无肢体血运障碍。但术后4例发生淋巴瘘。结论：注射海洛因所致的假性动脉瘤病史一般较长，且大多合并感染，人造血管移植手术有较大风险，应根据瘤体局部情况及肢体远端血运情况选择适当的手术。
