For high-risk patients, axillofemoral bypass (extra-anatomic technique) and percutaneous angioplasty are also viable alternatives (2, 3).
Aortic endograft infection (AGI) is a serious complication of aortic repair, and treatment involves prolonged antimicrobial drug therapy and complete or partial graft explantation with subsequent in situ or extra-anatomic arterial reconstruction.
For surgical treatment, the approaches included in situ reconstructions, extra-anatomic bypass, and endovascular stent repair.
For frankly infected grafts, surgical explantation with in situ reconstruction, or extra-anatomic bypass for high-risk patients has been shown to be feasible [8].
Recently, we successfully treated a young man affected by end-stage liver disease with grade 3b PVT performing an extra-anatomic jump graft from the right colic vein.
Current treatment approaches of PADF are en bloc resection and reconstruction with aortic graft, extra-anatomic bypass, and endovascular repair.
Unstable patients might benefit from stent graft (Level 4, Recommendation C); stable patients with aortoenteric fistula should receive staged procedure with extra-anatomic bypass first (Level 2c, Recommendation B); and finally stable patients without aortoenteric fistula (patients that do not have direct communication between proximal anastomosis and bowel but infected paraanastomotic sinus) should receive in situ revascularization using autogenous superficial femoral vein or aortoiliac allograft (Level 2c, Recommendation C) (2).

Open surgery techniques involve simple arterial ligation or ligation associated with femorofemoral bypass, direct suture, extra-anatomic bypass surgery, or angioplasty by patch [4].
An extra-anatomic femorofemoral bypass graft was constituted surgically in order to cure the claudication.
The vascular defect can be repaired by an open approach: local reconstruction, ligature of the vessel with or without extra-anatomic reconstruction (this reconstruction includes a femoro-femoral crossover bypass).
(7) Therefore, the authors of recently published treatment algorithms advocate endovascular therapy as a temporizing measure to stabilize the patient until the surgeon can perform a further workup to determine the risk of a cerebrovascular accident after occlusion or the need for an extra-anatomic bypass.
