Aorto-bifemoral revascularisation after radiation, peritonitis and colostomy.

The success of all vascular interventions depends mainly on the chosen strategy and access, especially in patients with severe co-morbidities, preceding operations or infection. In these cases the combination of retroperitoneal approach and extra-anatomical bypasses makes the revascularization possible. We present a clinical case of a patient after radiotherapy, peritonitis and colostomy with persistent pain in the lower extremities and angiographic finding of bilateral occlusion in the aorto-iliac segment. We did a right retroperitoneal aorto-femoral reconstruction and a crossover femoro-femoral bypass. It is also possible to perform visceral and renal arterial reconstructions with the retroperitoneal approach. In addition, symptomatic and ruptured aneurysms, as well as infected aortic grafts can be operated on with optimal results, without a notable increase in mortality.
