Abstract
- PURPOSE
The present study investigated clinical features of popliteal artery aneurysm (PAA) and evaluated clinical factors which cause poor outcomes of surgical management.
METHODS
From January 2004 to January 2011, 17 patients underwent surgical treatment at Asan Medical Center. Patient medical records and radiographic findings were retrospectively reviewed.
RESULTS
Twenty one PAAs were treated in 17 patients, consisting 15 men (88.2%) and 2 women (11.8%) and were diagnosed at a median age of 59 years (range: 24-88). The mean PAA diameter was 2.73+/-1.88 cm (range: 1.1-7.1 cm). Ten patients (58.8%) had bilateral PAAs. Four patients (19.0%) had abdominal aortic aneurysms, and 9 patients (42.9%) had other peripheral artery aneurysms. Acute limb ischemia was the initial presentation symptom in 9 patients (42.9%), and chronic limb ischemia was present in 9 patients (42.9%). One patient (4.8%) was asymptomatic. All patients received interposition or bypass surgery. The graft patency and limb salvage rate were 81.0% and 90.5%, respectively. Two of 3 cases (66.7%) of no distal run-off developed graft obstruction, while only 2 of 18 cases (11.1%) of patent distal run-off showed graft obstruction. However, no statistical significance was observed between graft obstruction and lack of distal run-off (P=0.080). The risk factor for amputation was no distal run-off (P=0.014).
CONCLUSION
The patency of distal branches was a contributing factor for improving the outcome of surgical management.
