Abstract
- PURPOSE
Popliteal artery entrapment syndrome (PAES) is rare but major cause of non-atheromatous popliteal arterial insufficiency in young. Because of its rareness, it is often neglected or misdiagnosed as thrombosis or embolism. Consequently surgeons would lose the appropriate time of treatment. METHOD: We reviewed 11 cases of PAES from 1994 to 2002 regarding to clinical characteristics, image findings, management and their results. RESULT: Two of 11 patients had bilateral involvement. All patients were male and aged 12 to 45 year old (mean; 32.1). Intermittent claudication was presented as initial symptom in all. One had toe gangrene. Conventional arteriography (11 cases) was used as initial diagnostic method. CT (7 cases) and MR (4 cases) angiography were also used to make diagnosis. Type II PAES were most common in 7 limbs. 11 limbs of 10 patients underwent operation. One was managed conservatively because of advanced liver cirrhosis. Resection of medial head of gastrocnemius and popliteal arterial bypass were performed in 7 limbs. One myectomy with femoroposterotibial bypass, one femoropopliteal bypass without myectomy, and myectomy with patch angioplasty were performed. Postoperative complication occurred in two limbs. One had occlusion of graft, another had occluded segment of endarterectomised popliteal artery. Primary graft patency at 6 mo, 1 yr and 3 yr were 81% 81%, 81% respectively.
CONCLUSION
In young patients with claudication who have localized lesion at popliteal artery, clinicians should pay attention to rule out PAES. Accurate diagnosis can be achieved by CT or MR angiography. Early surgical correction is recommended to minimize surgical procedure and reduce complication of the disease.
