The distal anastomoses are completed in an end-to- Aortoiliac Occlusive Disease 21 side fashion using flushing maneuvers before completing the anastomoses. It is very important to alert the anesthetic team before releaseing the clamp, to be prepared to avoid blood pressure drop with reperfusion. Once hemostasis is sufficient, the abdomen is irrigated and the retroperitoneum is closed. If adequate retroperitoneal coverage is not possible, particularly with an end-to-side proximal anastomosis, a sleeve of omentum should be fashioned to cover any exposed segment of the anastomosis and to separate the graft from the adjacent bowel.

The groin wounds are copiously irrigated with antibiotic solution, and the deeper tissue is closed in several layers using absorbable Vicryl sutures. Confirm adequate distal perfusion and ensure that no distal embolization has occurred. Although aortobifemoral bypass is easier and has better long term patency compared to aortobiiliac bypass, in certain circumstances performing an aortobiiliac bypass remains advantageous.

In patients with hostile groin creases from prior surgery or radiation therapy, or are obese, diabetic patients with an intertriginous rash at the inguinal crease and patent external iliac arteries, the impact of synchronous SFA disease on the results of AI revascularization remains undefined. Pulmonary complications are most likely to occur in the elderly or those with chronic obstructive pulmonary disease.

Acute renal failure following aortic reconstruction for occlusive disease is relatively uncommon in patients with normal preoperative renal function.

Adequate hydration and avoiding repetitive aortic cross-clamping and perioperative hypotension are valuable prophylactic maneuvers; the adjunctive use of mannitol and furosemide Lasix prior to aortic cross-clamping is less documented despite its wide use.

Intraoperative injury to the ureters during dissection, graft tunneling, intraoperative injury to the small and large bowel can usually be avoided with careful surgical technique. If compromised bowel perfusion is recognized intraoperatively inferior mesenteric artery reimplantation is indicated. Maintaining a high index of suspicion and having a low threshold for performing sigmoidoscopy during the early postoperative period are critical 50 Spinal cord ischemia is a devastating complication of aortic surgery and the main component of prophylaxis is careful preservation of hypogastric perfusion.

Fortunately, this complication is uncommon, occurring in only 0. If successfully restored, revising the distal anastomotic site with a profundaplasty or extension of the graft may prove necessary.

If restoring the flow through the graft is unsuccessful a femorofemoral or axillofemoral graft usually suffices as a secondary source of inflow.

Prosthetic graft infection is a particularly feared complication of aortic reconstruction, given its high associated morbidity and mortality.

Diagnosis can be established with CT if there is clinical suspicion. Once infection is diagnosed, graft excision is usually indicated and inflow established with extra anatomical bypass. The most common pathophysiologic process is erosion of the proximal aortic suture line through the third or fourth portion of the duodenum, although fistulae between the iliac anastomoses into the small bowel or colon are also well described.

Commonly presented with a small, self-limited bleed then become large or massive bleeding. Treatment is usually similar to that for graft infection; extra-anatomic bypass and graft removal are usually required, covering the aortic stump with adequate tissue coverage and repair of the involved gastrointestinal tract.

They arise secondary to a weakening in the suture line as a result of structural fatigue or fabric degeneration. Undue tension, poor suturing technique, and focal weakening of the recipient arterial wall have been implicated as causative factors.

Infection undoubtedly plays a role in many cases, despite the frequent absence of any obvious clinical signs; Staphylococcus species are the predominant organisms identified in culture. Femoral anastomotic false aneurysms are most common and typically present as a slowly enlarging, asymptomatic groin bulge.

Proximal anastomotic false aneurysms are often Aortoiliac Occlusive Disease 23 discovered incidentally or noted when they rupture. Enthusiasm for the procedure dimmed, however, with the introduction of prosthetic graft. An obvious benefit of endarterectomy is the elimination of the need for a prosthetic graft, making it an appealing alternative in the setting of infection.

Advocates have likewise pointed to the advantages of endarterectomy for younger patients or those with small vessels who are less than ideal candidates for endovascular therapy or aortobifemoral grafting. In patients with localized aortoiliac disease, aortoiliac endarterectomy may be suitable options and have excellent long-term patency rates, compare with aortic bypass grafting, have been reported. The increasing popularity of endovascular therapy is further decrease the small proportion of patients considered suitable for this reconstructive approach.

Hemodynamic studies confirm that one iliac artery can support both legs, at least at rest, in the absence of flow-limiting lesions in the planned donor iliac arterial system. The majority of the studies published have found that iliofemoral bypass yields somewhat better patency than femorofemoral bypass, assuming the presence of an appropriate common iliac artery for inflow to the graft.

Kretschmer and colleagues found no difference between femorofemoral bypass and unilateral iliofemoral bypass with respect to patency. Longitudinal incisions and less frequent oblique incisions are generally used to expose and control the femoral arteries on both sides.

The graft is tunneled from one groin incision to the other within the abdominal wall superior to the pubis. The tunnel is created bluntly with fingers, a large clamp, or a tubular tunneler. The graft tunneled in the prefascial subcutaneous plane or in the preperitoneal position if unfavorable conditions exist in the abdominal wall, such as prior surgery, radiation-damaged skin or other skin changes, an unusually thin subcutaneous fat layer, or obesity.

Kinking of the graft should be avoid by taking the graft lower on the common femoral to the origin of the profunda parallel to the artery.


A prosthetic graft is now used in nearly all cases. Exposure for the iliac site of the anastomosis usually done through suprainguinal curved incision which is simple also in the obese patient avoid the groin and the graft is more deepley placed and more cushioned than in the femoro femoral bypass.

It is not surprising that endovascular procedures to improve suboptimal donor iliac arteries might be considered prior to or concomitant with femorofemoral bypass. Axillofemoral bypass is an essential tool for the treatment of many patients with infected aortic or prosthetic arterial grafts or aortoenteric fistulae 53,54 Axillofemoral bypass is nearly always performed with general anesthesia.

Supine position. Either axillary artery can be chosen as a donor unless there is disease in the subclavian or axillary artery. The axillary artery on the side with the higher blood pressure is chosen if there is a 10 mm Hg or greater systolic pressure discrepancy between the arms. The pectoralis major muscle fibers are pushed superiorly and inferiorly, exposing the deep fascia and, beneath that, the fat containing the axillary vein, artery, and brachial plexus elements.

The axillary artery is exposed from the clavicle medially to the pectoralis minor muscle laterally, often requiring the ligation of crossing veins or small arterial branches.

Conventional longitudinal or oblique groin incisions are used for femoral artery exposure. It is very important to place the axillary graft anastomosis as medially as possible to avoid tension on the axillary anastomosis when the arm is abducted. The anastomosis of the proximal end of the graft to the side of the axillary artery is generally performed first.


The distal anastomosis is conventionally performed end to side to an appropriate artery in the groin. It is important to ensure adequate outflow.

It is also essential to ensure adequate blood flow in the donor arm beyond the axillary anastomosis. Patient with claudication do better than limb salvage patients because of the inherent outflow restriction in the latter group.

Patients with a previous distal bypass have better results. Patency was inferior to that expected with more conventional reconstructions. Nevertheless, this technique is occasionally the only reasonable approach to patients with groin sepsis.

However, its role in vascular surgery has yet to be defined. Several authors report aorto iliac surgical reconstruction performed laparoscopic ally or hand assisted.

It is likely that even patients with more advanced aortoiliac occlusive disease will be candidates for endovascular therapy by means of stent- 26 Vascular Surgery grafts and hybrid open-endovascular approaches. The indication for therapy is similar to the indication of open surgery. Patients with disabling claudication constitute the largest group of patients who undergo aortoiliac endovascular revascularization.

Patients with critical limb ischemia CLI manifesting as either rest pain or tissue loss frequently have multilevel occlusive disease. In patients with a significant CFA disease burden, combined femoral artery endarterectomy and patch angioplasty with simultaneous aortoiliac stenting or stentgrafting often provides adequate perfusion to treat CLI. Juxta renal aortic occlusion, circumferential heavy calcification, hypo plastic aortic syndrome, and adjacent aneurysmal disease.

Renal insufficiency is also a relative contraindication owing to potential contrastinduced nephropathy, although preventive regimens and minimal contrast techniques have reduced the impact of this complication.


Good-risk patients with TASC type C disease can also be treated with open surgery, depending on patient preference. Surgery is usually recommended for TASC D lesions, but advanced endovascular approaches are now being applied in these lesions as well, with good results.Peplau September 1, — March 17, [1] was an American nurse and the first published nursing theorist since Florence Nightingale.
