Proximal Aortic Coverage and Clinical Results of the Endovascular Repair of Juxta-/Para-renal and Type IV Thoracoabdominal Aneurysm with Custom-made Fenestrated Endografts

Juxta- (JAAA)/para (PAAA)-renal and type IV-thoracoabdominal (TAAA) aneurysms can be repaired by custom-made fenestrated endografts (CM-FEVAR). Differently from open repair, a relatively long segment of healthy proximal aorta needs to be covered to achieve a durable sealing, and this may be considered a disadvantage of the endovascular approach. We aimed to quantify the additional proximal aortic coverage in JAAAs, PAAAs, and type-IV TAAAs treated with CM-FEVAR and to evaluate its impact on early/follow-up clinical outcomes.
