In this study, we performed 16 surgical cases of popliteal artery aneurysms in 14 patients. Acute limb ischemia (ALI) was the most frequent initial symptom seen in 10 cases, which accounted for 10.5% of all our ALI cases over the same period. Included in the ALI group were patients with both acute and chronic symptom. 12 limbs within this group expressed limb ischemia. Operative technique was determined according to the site of aneurysm and whether it was a thrombosed popliteal artery aneurysm or not. On three limbs we performed exclusion and bypass grafting, in other cases we performed aneurysmectomy and graft interposition. There was no significant difference in relation to efficacy between two operative techniques. In cases that had symptoms of ALI, we added image-guided thrombectomy. There were no cases that resulted in limb necrosis or that required for amputation.

Treatment of the post-thrombotic syndrome (PTS) is mainly conservative therapy such as patient education that utilizies self-management techniques and compression therapy, but its impact sometimes is limited. We performed endovascular therapy (EVT) of the iliofemoral vein using a balloon and a stent for two cases of PTS (CEAP clinical class 3, contraindication for compression therapy). Thrombolytic agent was not administered because of the thrombus was organized. After successful EVT, leg swelling receded within three days. EVT for PTS is an effective therapy for symptomatic patients.
