Gerota's fascia flap: an alternative for aortic graft coverage

The greater omentum is commonly used when there is a surgical indication for a barrier between an aortic graft and the abdominal contents. There are few other options when the omentum is not available. A novel approach is described for this purpose-Gerota's fascia flap. It is a simple, durable technique that can readily be used to provide extra tissue in the retroperitoneum for coverage of an aortic graft or possibly an aortic stump.
