The following publication was reviewed: ¿safety and efficacy of using the viabahn endoprosthesis for percutaneous treatment of vascular access complications after transfemoral aortic valve implantation¿ (ole de backer et al., the american journal of cardiology, accepted january 28, 2015).Over a 40-month period, a total of 380 patients underwent transcatheter aortic valve implantation (tavi) in a single-center using the self-expanding corevalve (medtronic, minneapolis, mn).Access-related complications (vac) leading to acute intervention occurred in 72 patients (20.3%) of the study population.Minor vascular injury at the puncture site was treated with either external compression or balloon angioplasty for 3 to 5minutes.If this strategy failed or when major extravasation was apparent on angiographic control, a 50-mm-long gore® viabahn® endoprostheses (vb) was inserted covering the vessel lesion, aiming to place the distal part of the stent proximal to the bifurcation of the common femoral artery (cfa) into superficial femoral artery (sfa) and deep femoral artery (dfa).Vb were used for different types of vac: stenosis (n=3), dissection (n=4), incomplete vascular closure due to closure device failure (n=36), and rupture/perforation (n=5).The use of vb was the primary choice in 38 patients, whereas in 10 other patients, stenting was preceded by balloon angioplasty with unsatisfactory result.It was stated that major or life-threatening bleeding was observed in 8.4% oft he vb subgroup.Blood transfusion was given to 22.9% patients in the vb subgroup.It is not described if the bleeding and required blood transfusion is related to the vb implant procedure is singularly related to the vac.
