Question on triple A repair

[rearviewmirror, BSN, RN]

Hello, sirs and madams. Where better is there for me to ask about operations than in the forum packed with OR geniuses!?

As the video I youtubed for better understanding of the surgery showed, it seemed like the vessels distal and proximal to the aortic aneurysm was mechanically obstructed with some hemostat-like surgical instruments, thereby isolating the aneurysm and the blood and contents inside it so the surgeon could incise, removed ruptured tissues and suture up the synthetic plastic looking vessel for bypass (apologies for layman's term, I'm not familiar with OR terms :)) My question is, how does the OR team handle the back flow that occurs due to purposeful obstruction? Thanks for your time

Most AAA's are now repaired endoscopically, in hybrid OR's where grafts are placed through the femoral with x-rays-even if ruptured, so back to your question. The backflow is handled by limiting the clamp time, doctor's must move fast. Also anesthesia regulates the blood pressure and fluid replacement during the case. It is not so much the backflow but the obstructive issues with lack of circulation to the periphery dependent on the aortic level of the aneurysm. Open abdominal aneurysm repair continues to have a high morbidity and mortality rate. The key is to have a physical to detect an aneurysm before it becomes the size of an orange.
