Aortoiliac occlusive disease and abdominal aortic aneurysm in patients with renal insufficiency on hemodialysis can significantly influence the success of renal transplantation. In the recent past, advanced atherosclerosis was considered as contraindication for renal transplantation. Complicated creation of vascular anastomoses and progression of occlusive or aneurysmal disease were the main reasons.

Aortoiliac occlusive disease, which is also referred to as Leriche syndrome, is a chronic atherosclerotic occlusive disease that occurs at the level of the aortic bifurcation. It is often thought to present with a triad of clinical symptoms: (1) intermittent lower extremity vascular claudication, (2) impotence, and (3) weak/absent femoral pulses.
We report a case of a 47-year-old Caucasian woman who presented with an acute inferior ST-elevation myocardial infarction.

Femorofemoral crossover bypass is a surgical arterial revascularization modality which is commonly performed for unilateral aortoiliac occlusive disease. It is primarily applied to patients with intermittent claudication or critical limb ischemia in whom underlying anatomic constraints rule out endovascular means of restoring in-line flow and those who do not qualify for anatomic reconstruction due to the comorbid conditions that preclude a more invasive open surgical approach. This surgical procedure may be also used as a complementary component of endovascular repair of abdominal aortic aneurysms when one aortoiliac arterial system is occluded to ensure exclusion of the aortic aneurysm.

Endovascular intervention has become the mainstay for treatment of most patients suffering from peripheral vascular disease. We describe a patient with a known nickel allergy who underwent placement of a stainless steel stent for aortoiliac occlusive disease. Despite our attempt to avoid a nickel-containing stent, the patient developed a diffuse rash consistent with a nickel or metal allergy.

Critical limb ischemia (CLI) often results from multilevel occlusive disease. There are occasions where a patent profunda femoral artery (PFA) is the only target artery that can be used as outflow during reconstruction to bypass aortoiliac disease (AOID), with no further option for infrainguinal revascularization. We aim to report results of the use of PFA as the sole target vessel for the treatment of these patients.

Surgical management of advance aortoiliac occlusive disease is time-tested and a widely practiced strategy, particularly when there is significant coronary artery disease associated with aortoiliac occlusive disease. The technological advances in the field of percutaneous techniques have facilitated the use of nonsurgical endovascular alternatives for peripheral arterial disease in patients with significant comorbidities at high surgical risk, as illustrated in our case report. We report a case of chronic total occlusion of the aorta that was treated percutaneously with endovascular stenting.

Fenestrated and branched endovascular aneurysm repair (FB-EVAR) is a valid option to treat juxtarenal and pararenal abdominal aortic aneurysms and thoracoabdominal aortic aneurysms. Because successful deployment depends on complex maneuvers, hostile iliac artery anatomy (HIA) can prejudice the FB-EVAR outcome. The aim of the study was to evaluate the impact of HIA on FB-EVAR outcome.

According to the 2007 TransAtlantic Inter-Society Consensus (TASC II) guidelines, surgery is the preferred treatment for extensive (TASC II type C and D) aortoiliac occlusive disease (AIOD). Recent studies, however, have shown that endovascular management can be an effective first-line treatment option for TASC II type C and D categories. While endovascular therapy is now commonly performed in patients with TASC II type D lesions, very few studies have investigated the feasibility and effectiveness of extending endovascular therapy to the most severe subcategory of TASC II D lesions, chronic infrarenal aortoiliac occlusion (CIAO).

Covered Endovascular Reconstruction of Aortic Bifurcation (CERAB) is a new technique to treat extensive aortoiliac occlusive disease with covered expandable stent grafts to rebuild the aortoiliac bifurcation. Post stenting Doppler ultrasound (DUS) measurement of maximum peak systolic velocity (PSV) in the stented segment is widely used to determine patency and for follow up surveillance due to the portability, affordability and ease of use. Anecdotally, changes in hemodynamics created by CERAB can lead to falsely high PSVrequiring CT angiography (CTA) for further assessment.

Treatment of thoracic aortic aneurysms constitutes high mortality and morbidity rates despite improvements in surgery, anesthesia, and technology. Endovascular stent grafting may be an alternative therapy with lower risks when compared with conventional techniques. However, sometimes the branches of the aortic arch may require transport to the proximal segments prior to successful thoracic aortic endovascular stent grafting.

Collateral pathways in aortoiliac occlusive disease are essential for arterial blood flow to the abdomen, pelvis, and lower extremities. These pathways can be broadly divided into systemic-systemic, visceral-visceral, and systemic-visceral collateral networks. MDCT angiography is the most commonly used modality for the diagnostic evaluation of patients with aortoiliac occlusive disease, allowing excellent evaluation of stenotic arterial segments, as well as beautifully illustrating resulting collateral pathways (particularly when utilizing 3D reconstruction techniques).

Vladimir Lakhter, Vikas Aggarwal
Aortoiliac occlusive disease (AIOD) is widely prevalent and leads to significant limitations in patient quality of life. All patients with aortoiliac occlusive disease should be managed with approved medical therapies in addition to a supervised exercise program. Persistence of significant symptoms despite noninvasive therapy should prompt further management with endovascular revascularization.

Chronic aortoiliac occlusive disease most often affects the common iliac arteries and distal aorta but can progress all the way to the renal arteries, occluding the inferior mesenteric artery. A compensatory collateral network typically develops to preserve lower body perfusion. Inadvertent compression or ligation of such collaterals during surgery can have catastrophic consequences.
