Clinical evaluation of covered stents in the treatment of superficial femoral artery pseudoaneurysm in drug abusers.
The present study aimed to investigate the technical feasibility and initial clinical outcomes of a covered stent for the endovascular treatment of superficial femoral artery (SFA) pseudoaneurysm in drug abusers. A total of 29 drug abuse patients with SFA pseudoaneurysm, as confirmed by color Doppler sonography, were enrolled to the present study between January 2012 and May 2014. All patients were treated percutaneously by implantation of a covered stent. Physical examination and lower extremity computed tomography angiography were performed at 1 and 9 months postoperation. Furthermore, the ankle‑brachial index (ABI) of all patients was measured. The results indicated that placement of the covered stent was technically successful in all 29 patients. All of the ruptured pseudoaneurysms were successfully sealed with no cases of intraprocedural mortality. In addition, all patients' conditions improved rapidly; active hemorrhage subsidence and vascular bruit disappearance were immediately detected following implantation of the covered stent. During the follow‑up period, pain was markedly alleviated and pulsatile mass was decreased as time increased. No complaints or complications were documented. A total of 9 months postoperation, pain and pulsatile mass were not detected. The patency rate of the stent was 100%, and no migration, occlusion or infection was detected. In addition, the ABI was significantly improved, from 0.52±0.09 to 0.97±0.37 (P<0.01). In conclusion, the placement of a covered stent may be considered a promising approach to provide an effective, safe and minimally invasive option for the treatment of SFA pseudoaneurysm in drug abusers.
