This study compares outcomes of FEVAR for juxta-/pararenal aortic aneurysms based on the location of the proximal seal: supraceliac (above the celiac artery) versus infraceliac (below the celiac artery). The study found that supraceliac sealing was associated with a lower risk of type-IA endoleaks but a higher risk of certain complications. The researchers concluded that while supraceliac sealing might offer some benefits, clinicians need to be aware of the increased risk of perioperative morbidity.
Clinicians should carefully evaluate patients undergoing FEVAR for juxta-/pararenal aneurysms to determine the optimal proximal sealing zone, considering the potential risks and benefits of supraceliac versus infraceliac sealing.
Given the increased risk of complications associated with supraceliac sealing, meticulous surgical technique and postoperative monitoring are crucial to minimize perioperative morbidity.
Longer-term studies are needed to evaluate the durability of FEVAR with different proximal sealing zones and to comprehensively assess the risks and benefits of utilizing a higher sealing zone within the visceral aorta.
