Endovascular aneurysm repair (EVAR) has become one of the most important treatments for aortic abdominal aneurysm. This method has some possible complications, including a type II endoleak (T2E). When coexisting with arteriovenous fistulas (AVF), T2E can lead to serious hemodynamic consequences and organ failure. This report describes the management of a patient with T2E coexisting with AVF following an EVAR and re-EVAR procedure. Although T2E itself may be treated with a conservative approach in some cases, in the presented patient an operative approach was necessary because of coexisting AVF. In addition, due to unusual hemodynamic conditions created by concomitant ACF and T2E, fistula closure was obtained as a result of transarterial inferior mesenteric artery embolization. Post-EVAR imaging, including ultrasound and computed tomography angiography, has proven to be essential when caring for these patients.

The development of aneurysms of thoracoabdominal aorta (TAAA) in a post-transplant patient is a rare clinical situation and requires special attention. Endovascular treatment is the most suitable option for these patients due to numerous comorbidities. Particular emphasis should be placed on the ejection fraction as one of the main criteria for qualifying for surgery. The treatment itself remains a major challenge relating to anatomical constrains; however, it is possible in select patients in experienced centers.
