ABSTRACT
Objective To investigate the clinical application and value of retrograde catheterization via superficial femoral artery for the treatment of limb chronic total occlusive disease (CTO). Methods Fifty-nine patients with proximal and middle occlusive lesions of superficial femoral artery from Jan. 2013 to Jan. 2015 in department of emergency surgery were retrospectively analyzed. Percutaneous transluminal angioplasty (PTA) together with stent implantation was performed to reopen the all narrowed or obstructed superficial femoral artery.Seventeen patients received ipsilateral retrograde catheterization via superficial femoral artery together. The length of the diseased artery ranged from 6.5 to 13.4 cm, with a mean of (8.3 ± 2.9) cm, including right (11 cases)and left (8 cases) femoral arteries. After the interventional therapy patients were followed up for 1- 24 months. Results All patients were treated successfully. The proximal and middle occlusive lesions of superficial femoral artery were reopened.No serious complications were found including nerve and vessel damage+After the treatment, the ischemic symptoms were markedly improved or even disappeared. In 14/19 of patients the superficial femoral arteries remained patent during the follow-up period. The ankle preoperative brachial index (ABI) was 0.20 to 0.51 (0.39 ± 0.06), while the postoperative ABI was 0.65 to 1.15 (0.74 ± 0.13). The difference in ABI between pre-operation and post-operation was statistically significant (P<0.05). Conclusions Retrograde catheterization via superficial femoral artery is an effective alternative to treat proximal and middle occlusion of ipsilateral superficial femoral artery. It has high successful rate and safety.
