Abstract:
Objective To discuss the feasibility, safety and validity of the use of ViabahnTM self-expanding covered stent in endovascular repair of peripheral traumatic pseudoaneurysm (TPA). Methods During the period from June 2012 to April 2014, a total of 8 patients with peripheral TPA were admitted to the Department of Vascular and Endovascular Surgery of Shanghai Changzheng Hospital . The clinical data were retrospective analyzed. The lesions were located at the common carotid artery (n=4), vertebral artery (n=1), subclavian artery (n=1) and superficial femoral artery (n=2). On the basis of acute and chronic TPA classification and different therapeutic principles, endovascular repair with ViabahnTM self-expanding covered stent was employed in 8 patients. Intraoperative angiographic findings, the size and number of the implanted stent, and the immediate angiographic results after stent implantation were recorded. All the patients were followed up to evaluate the improvement of the symptoms, the effectiveness of the repair of TPA cavity, and the occurrence of endoleak or restenosis. Results Successful implantation of ViabahnTM self-expanding covered stent was accomplished in all 8 patients, with a technical success rate of 100%. Angiography performed immediately after stent implantation showed that complete repair of TPA cavity was obtained in all patients, the distal segment of the parent artery was patent, and no endoleak was observed. The sizes of the stent used in the patients were 8×50 mm (n=2) and 9×50 mm (n=2) in common carotid artery, 6×50 mm (n=1) in vertebral artery, 11×100 mm (n=1) in subclavian artery, and 8×100 mm (n=2) in superficial femoral artery. The patients were followed up for 6-30 months (mean of 14.3 months), and the clinical symptoms disappeared in all patients. CT angiography indicated that there was no endoleak or restenosis. Conclusion Based on the different therapeutic principles, the use of ViabahnTM self-expanding covered stent in endovascular repair of peripheral TPA is technically simple and micro-invasive, and clinically feasible with reliable effect and safety. Therefore, this technique can be employed as a first-line therapy option for peripheral TPA.
