RESUMO
BACKGROUND: Vascular complications are frequent in the context of transcatheter aortic valve replacement and may require the implantation of a covered stent graft in the common femforal artery. However, common femoral artery is considered to be at high risk of stent fracture or occlusion due to high mobility of the hip joint. PATIENTS AND METHODS: We analyzed medical records of patients with transcatheter aortic valve replacement related vascular complications between 2015 and 2018, treated with commom femoral artery transluminal angioplasty or surgery. Vascular complications or suspect symptoms were followed up by phone calls. RESULTS: Among 552 patients, 43 patients were included. Twelve (11.6 %) were managed by prolonged balloon inflation, 5 (11.6 %) by first line surgery and 26 (60.4 %) by the implantation of a covered stent graft. Among the latter group, the covered stent graft was efficient in 24 patients (92.3 %). The median follow-up was 430 days [3-1499]. The first-line surgery group had a higher risk of red blood cell transfusion and all causes mortality. At follow-up, no patient had suspicious symptoms of vascular covered stent complication. Four patients (9.3 %) had US-doppler or CT vascular imaging at follow-up, showing no evidence of stent fracture or occlusion. CONCLUSION: In our study, the implantation of a covered stent graft in the common femoral artery was an efficient and safe strategy for the management of transcatheter aortic valve replacement related vascular complications.
