Long-Term Outcomes of Endovascular Aortic Repair with Parallel Chimney or Periscope Stent Grafts for Ruptured Complex Abdominal Aortic Aneurysms

: Treatment of ruptured complex abdominal aortic aneurysm with the PGEVAR technique is associated with acceptable perioperative and long-term outcomes with high PG patency rates. Early proximal T1aELs are observed with a relevant frequency, requiring early reintervention with successful sealing of most relevant endoleaks. To note, limitation of the number of parallel stent grafts implanted at the proximal aortic sealing sites, sufficient PG sealing length, and adequate main aortic SG oversizing are most relevant to avoid T1a (gutter) ELs. The selection of juxtarenal aortic aneurysms and evidence for aneurysm sac diameter regression after PGEVAR had a prognostic impact.
