Our experience with staple aneurysmorrhaphy shows that it is an effective, safe, and durable procedure to preserve a functioning autogenous AVF with complicated aneurysmal degeneration. Key principles are to reduce the vein to normal adjacent diameter and to provide healthy skin coverage. The remodeled AVF has a low aneurysm recurrence rate and maintains the beneficial properties of superior patency and low infection. It is important to aggressively monitor for and treat proximal outflow venous stenoses to prevent aneurysm recurrence. The surgery can be done safely under local anesthesia in selected patients.

Retrograde superior mesenteric artery stenting (ROMS) represents a significant development in the treatment of acute mesenteric ischemia. Compared to traditional surgical mesenteric bypass, ROMS is a less invasive technique that avoids many complications associated with emergent mesenteric bypass. This case report illustrates that retrograde superior mesenteric artery (SMA) stenting is an option for the treatment of acute mesenteric ischemia for patients in extremis.
