Temporary Gutter Endoleak to Reduce Renovisceral Ischemia During Urgent In Situ Laser Fenestrated Paravisceral Aortic Aneurysm Repair: Technical Note

The above-described techniques for gutter endoleak creation during emergent pAA repair with ISLF can potentially reduce reno visceral ischemia and increase the ISLF technique's safety.Clinical ImpactThe ISLF technique for pAA repair typically requires coverage of the visceral arteries with unpredictable ischemia time until laser fenestrations are established. The gutter endoleak technique reduces the renovisceral ischemia and potentially increases the safety of the ISLF repair.
