The utility of Prostar XL percutaneous vascular closure device after stent-graft implantation for infrarenal abdominal aortic aneurysms
Abstract
Introduction. Over time, endovascular techniques of abdominal aortic aneurysm repair became the principal methods of treatment of this potentially fatal disease. Currently, endovascular aneurysm repair (EVAR) constitutes an effective alternative to open surgery, also in cases of aneurysm rupture. Low degree of invasiveness is the main advantage of this method. Introduction of a system enabling percutaneous stent-graft implantation appears to be the next step in the development of endovascular AAA surgery. Aim of the study is to evaluate the Prostar XL® closure device with regard to clinical effectiveness, safety, cost-effectiveness. Material and methods. The study included 100 patients (from January 2013 to December 2015) subject to endovascular abdominal aortic aneurysm repair in the infrarenal region of the aorta with the application of the Prostar Xl® closure device. Most patients were operated under epidural anaesthesia. Local anaesthesia (1% Lidocaine) was used in 36 patients due to comorbidities. A possible application of the closure system depended on a preoperative assessment of common femoral arteries using ultrasonography. Presence of atherosclerotic plaque on the anterior wall of the vessel disqualified the patient from percutaneous endovascular aneurysm repair (PEVAR). The main part of the procedure consisted of stent-graft implantation into the abdominal aortic aneurysm. In the final stage, puncture site on the anterior wall of common femoral arteries was closed using previously placed sutures of the Prostar XL system. The wound in the inguinal region was closed with a skin suture. Results. The analysis of obtained results demonstrated significantly shorter mean hospitalization times in patients treated with PEVAR compared to EVAR. Low rates and types of observed complications in the study group (PEVAR) compared to the control group (EVAR) are strongly in favour the percutaneous technique (PEVAR) of endovascular aortic abdominal aneurysm repair in the infrarenal region of the aorta, confirming its minimally invasive character.
