Rupture of false aneurysm of the femoral artery caused by blunt trauma

The successful surgical repair of a ruptured false aneurysm of the left femoral artery in a 44-years-old male is presented. He was admitted to this hospital with the chief compliant of marked swelling accompanied with severe pain of the left thigh and the past history of a blunt trauma 7 years ago on the left groin? He had also severe anemia with hb 4.4 g/dl. An aneurysm measuring 15 by 8 cm was detected on the arteriogram. The aneurysm was treated by resection and implantation of Gore-Tex graft with good result. The pathological findings strikingly suggested that the false aneurysm was caused by the old blunt trauma. A false aneurysm of femoral artery caused by a blunt trauma is very rare and it's complications include acute arterial occlusion, subsequent ischemic change of lower limb and massive bleeding by the rupture. In conclusion, early diagnosis and surgical treatment are essential for a false aneurysm of femoral artery.     

A secondary bleeding false aneurysm of the superomedial genicular artery after distal femoral epiphysiodesis: a case report

A 16-year-old male developed a false aneurysm of the superomedial genicular artery five weeks after medial distal femoral epiphysiodesis. The aneurysm was revealed by inexhaustible bleeding from the medial aspect of the knee and the presence of acute hemorrhage which resolved spontaneously. Physical examination disclosed disunion of the surgical wound at the apex of a pulsatory tumefaction over the medial aspect of the knee. AngioCT enabled the diagnosis of a false aneurysm of the superomedial genicular artery. Emergency surgery was undertaken to drain the hematoma and exclude the false aneurysm by ligating the superomedial genicular artery.     

Risk of rupture of postangiographic femoral false aneurysm.

The surgical management of 50 false aneurysms caused by transfemoral arterial catheterization was reviewed to document the incidence and effects of rupture before repair. Twelve false aneurysms ruptured, leading to shock in six patients, distal ischaemia in three and stroke in one. The mean(s.d.) time from catheterization to rupture was 2.8(1.7) (range 1-6) days. Postoperative complications occurred in seven patients with ruptured and eight with non-ruptured aneurysms (P < 0.04). The mean(s.d.) age of patients with ruptured aneurysms was 67.2(6.3) (95 per cent confidence interval 63.5-70.8) years and those without 58.5(9.1) (95 per cent confidence interval 55.3-61.7) years (P < 0.008). On multiple regression analysis, age, peripheral vascular disease and raised plasma liver enzyme levels on admission were found to be significant independent predictive variables for rupture (all P < 0.05). It is recommended that patients with these risk factors undergo urgent operative correction of femoral false aneurysm.     

注射毒品所致假性股动脉瘤18例的外科治疗

目的 探讨注射毒品所致假性股动脉瘤的外科疗法。方法 对18例注射毒品所致辞假性动脉瘤患者的临床资料进行回顾分析。13例直接采用ePTFE人工血管行旁路髂外动脉和股浅动脉端侧吻合术；3例采用自体大隐静脉间置移植术，其中１例吻合口破裂出血改用ePTFE人工血管行旁路髂外动脉和股浅端侧吻合术；2例股动脉结扎术。结果 全部病例保肢成功。血管移植术后复查彩色多普勒超声显示移植血管通畅。结论 在患者不能提供合适的自体大隐静脉移植时，人工血管移植仍是治疗假性股动脉瘤的有效方法。术中彻底清创及避免污染是预防术后人工血管并发感染的最主要措施     

Reoperation for femoral anastomotic false aneurysm. A 15-year experience.

An experience on the surgical treatment of anastomotic false aneurysms during the last 15 years was reviewed. Fifty-nine were femoral anastomoses complicated by false aneurysm appearance requiring surgical excision. They represented 2.9% of all femoral anastomoses performed, whereas they represented 3.3% when considering reconstruction in which the femoral artery was the distal anastomosis. Reconstructions with distal anastomosis performed on the femoral artery were primarily involved (58 of 59), whereas grafts with "take off" from the femoral artery were rarely affected (p less than 0.05). A higher incidence of false aneurysm formation was demonstrated in hypertensive patients (p less than 0.05) as well as those who previously had femoral thromboendarterectomy (p less than 0.01). Infection was considered a causative factor even if it developed before (6-14 months) false aneurysm appearance. When a false aneurysm was resected, the best hemodynamic reconstruction, to avoid recurrence, was considered a bypass with distal anastomosis performed end-to-end on the femoral artery (p less than 0.05). The surgical treatment of choice was false aneurysm resection and graft interposition. However, a reanastomosis in the presence of small false aneurysms, when technically possible, has been successfully performed. Both treatments allowed good long-term results.     

Common femoral artery injury secondary to bicycle handlebar trauma

Blunt trauma from bicycle handlebars is associated with well-described injuries of the abdominal viscera. These injuries result from the forceful compression of the relatively immobile abdominal organs between the handlebar end and the vertebral bodies. The common femoral artery is also immobile as it passes anterior to the superior pubic ramus, rendering this vessel susceptible to a similar mechanism of injury. We have treated two children who sustained thrombosis of the common femoral artery caused by bicycle handlebar trauma. The lack of familiarity with this uncommon mode of injury may contribute to delayed diagnosis and increased morbidity. We therefore wish to draw attention to this mechanism of injury.

Surgical policy in false aneurysm of proximal anastomosis secondary to reconstruction of aortofemoral segment

The results of surgical treatment of 10 patients with a false aneurysm of the proximal anastomosis are analyzed. An average time for development of a false aneurysm made up 57.2 months. Fluorlon-lavsan vascular woven prosthesis of Russian produce was used in primary reconstruction. Bacteriological examination of operation material was carried out in 9 patients. 8 cases revealed the growth: of Staph. aureus (4) epidermal staphylococcus flora (3) and Proteus vulg. (1). The authors suggest that surgical treatment of patients with false aneurysms of the proximal anastomosis should consist in resection of the aneurysms and revascularization of the extremities from the proximal segment of the aorta with partial or total removal of the old vascular prosthesis. The application of this method in 7 patients allowed to avoid the repeated development of false aneurysms during a mean follow up period of 4.1 years.     

注射毒品致股动脉感染性假性动脉瘤的血循环功能重建

目的探讨注射毒品致股动脉感染性假性动脉瘤的血循环重建方法。方法 2003年11月-2009年5月,收治84例因注射毒品致股动脉感染性假性动脉瘤患者。其中男67例,女17例;年龄19～51岁,平均34.6岁。注射毒品时间1～11年,平均2.7年。13例股动脉缺损3～10 cm,其余患者股动脉破口范围1.0 cm×0.3 cm～3.0 cm×0.7 cm。5例行ePTFE人工血管旁路转流,29例行自体大隐静脉移植,24例行股动脉破口修补,26例行股动脉结扎。结果 2例患者术中下肢深静脉血栓脱落致肺栓塞死亡。8例术后出现切口感染,拆除部分或全部缝线,经换药后切口愈合,其余患者切口均Ⅰ期愈合。56例行血管重建或修补的患者,术后足背动脉搏动恢复或增强,无远端肢体骨筋膜室综合征发生;26例行股动脉结扎的患者,术后1周行CT下肢动脉血管重建或下肢动脉造影显示肢体远端均有丰富来自同侧髂内动脉、臀上动脉以及对侧髂内动脉的侧支循环。82例术后获12～36个月随访,平均17.3个月。3例出现间歇性跛行,经扩血管,活血化瘀等药物治疗后好转,肢体功能良好;其余行走正常。结论注射吸毒致股动脉感染性假性动脉瘤应尽早外科手术治疗,彻底清创引流、髂外动脉-股浅动脉旁路带支撑环人工血管或大隐静脉重建以及破口修补,是有效的治疗方法。在感染严重、局部条件无法重建血管的情况下,结扎股动脉也是一种可行选择。
