腘动脉陷迫综合征的影像学诊断与手术治疗

Imaging diagnosis and surgical treatment of popliteal artery entrapment syndrome

摘要:

目的 总结腘动脉陷迫综合征(popliteal artery entrapment syndrome,PAES)的影像学诊断与手术治疗经验.方法 本组11例(13条下肢)PAES患者,经CTA和MR(A)等检查确诊.其中男8例,女3例,平均年龄(28±19)岁;2例累计双下肢.间歇性跛行是最主要的症状.12条肢体术前踝肱指数(ankle brachial index,ABI)平均为0.47±0.27.结果 影像学结果 证实:6条患肢为Ⅰ型,3条患肢为Ⅱ型,3条患肢为Ⅲ型,另外1条患肢为Ⅳ型.11例患者中12条患肢接受了腘动脉探查或周围组织松解术,其中7条因动脉闭塞或动脉瘤同时施行了大隐静脉旁路移植术.本组随访11例(12条患肢),随访时间0个月至6年,平均(19 ±20)个月.术后平均ABI为0.81±0.30,较术前显著提高(P<0.05),其中1例患者术后第1天死于肺栓塞,1例患者(1条患肢)术后腘动脉血栓形成,其他手术肢体间歇性跛行症状治愈.结论 腘动脉陷迫综合征的早期确切的影像学诊断和及时的外科治疗是至关重要的.

Objective To summarize the experience on imaging diagnosis and surgical treatment for popliteal artery entrapment syndrome (PAES). Methods From 2004 to 2010, 11 patients (12 limbs) diagnosed as PAES by CTA and MR ( A) underwent surgery. There were 11 patients with a mean age of (28 ±19) years, eight patients were male, three patients were female. Two patients were found to have bilateral involvement. Intermittent claudication was the most frequent presenting symptom. Six limbs were type Ⅰ , three limbs were type Ⅱ , three limbs were type Ⅲ , one limb was type Ⅳ. The preoperative mean ABI was 0.47 ± 0. 27. Results Popliteal artery exploration surgery or peripopliteal artery lysis was performed in 12 limbs, and this procedure was combined with a great saphenous vein bypass graft in seven limb because of arterial occlusion or aneurysm. After a median follow-up of ( 19 ± 20) months (0 month to 6 years) , the mean ABI improved to 0. 81 ±0. 30, which was significantly higher than that of preoperation( P < 0.05),one patient died of pulmonary embolism one day after operation, one patient (one limb) had popliteal artery thrombosis after operation. Intermittent claudication symptoms disappeared in all other patients. Conclusions Timely imaging diagnosis and surgical intervention is very important for patients of PAES.
