Clinical research on the application of VIABAHN stent in the treatment of branching area lesions in lower extremity arterial diseases

Abstract

Objective To explore the security and the short term efficacy of VIABAHN stents in the treatment of branching area lesions in lower extremity arterial diseases. Methods The data of 16 patients (11 male and 5 female, aged 59.0 to 81.0 with median of 71.6) with lower extremity arterial occlusive disease from November 2014 to June 2015 were analyzed retrospectively. All lesions were located around the branching area of the lower extremity artery (3 cases in the internal iliac artery orifice, 6 cases in the deep femoral artery orifice and 7 cases in the vascular net around the knee). The short-term effects on these patients in the follow-up period, such as the success rate of surgical technique, the improvement of symptoms and the incidence of complications were summarized. Results Revascularization was technically successful in all 16 patients, and ischemic symptoms relieved significantly after the operation. The ABI were 0.36±0.12 before and 0.89±0.10 after the operation. The patients were followed up for 3 to 9 months (median 5.5 months). All the patients were achieved limb salvage and no complication occurred. Conclusions VIABAHN stent is safe and effective for the treatment of lower extremity arterial occlusive disease. The branches around the lesion can be covered with VIABAHN stents. Key words: Arterial occlusive diseases; Lower extremity; Cover stent
