Clinical application of covered stent in peripheral vascular disease

Objective: To evaluate the clinical application of covered stent in peripheral vascular disease by retrospective analysis of 11 patients. Methods: 11 patients(male 5, female 6, mean age 45y)were undertaken angiography and diagnosed as aneurysm in 8 patients, arteriovenous fistula in 2, and vascular injury in 1; with 2 involving subclavian artery, 1 common carotid artery, 1 renal artery, 5 iliac artery, 1 femoral artery, and 1 anterior tibial artery. All the patients underwent covered stent implantation to isolate the diseased segment from the vascular trunk through percutaneous femoral artery approch. Results: All the patients were successfully implanted with covered stent, and the lesions vanished on angiography after operation. During the procedure, 1 patients showed vasospasm but no other complications such as thrombosis or angiorrhexis. No recurrence and no vascular occlusion were found after follow-up of 3-6 months by B ultrasonic or DSA. Conclusions: Covered stent implantation is safe, efficient for treatment of peripheral vascular disease and worthy to be recommended. (authors)
