Kissing covered stents versus aortobifemoral bypass in patients with Leriche syndrome

Background: Leriche syndrome is the most challenging type of occlusive aortoiliac disease for the surgical treatment. Historically, it has been treated by open surgical repair with good results on patency rates. Endovascular surgery appeared as a safe and feasible technique with lower rates of morbimortality than open repair. In the last years, endovascular devices and techniques have evolved as such as the experience of the vascular surgeons. Endovascular approach with kissing covered stents is presented as a safe and reliable alternative to open repair in patients with Leriche syndrome. Objectives: To compare primary patency rates in 5 years term of endovascular with kissing covered stents vs. aortobifemoral bypass in patients with Leriche syndrome. Secondary objectives are to analyse the mortality within the first 30 days, the need for conversion to open surgery, the need for reintervention, the secondary patency and the impairment of kidney function. Methods: Randomized, controlled clinical trial. Patients with Leriche syndrome who meet all the criteria will be randomized for surgical treatment with aortobifemoral bypass or endovascular approach with kissing covered stent
