Post EVAR endovascular revision of late onset stent graft collapse due to Type 1 endoleak in a complicated case with left limb occlusion and solitary kidney

Abstract

Type 1 endoleak is one of the most frequent complication usually seen at the initial phase of EVAR procedure. B alloon dilatation is mostly used to oversize the proximal or the distal part of the orifice to stabilize the attachment of the graft stent to the aortic wall. Late onset of type 1 endoleak with graft stents may cause severe lumen compression of the stent and aneurysm enlargement which might cause a serious problem especially in a patient whose graft stents left iliac branch is thrombosed and the left leg is supplied by the bypass graft from right CFA. Although operation was advised by the endovascular specialists the procedure was done in our hospital as the patient preferred the endovascular method instead of open surgery.
