Abstract

The aortoaortic concept for endovascular repair (EVAR) of infrarenal abdominal aortic aneurysms (AAAs) is nearly forgotten but may constitute a valuable option for focal pathologies. Herein, we describe our experience using custom-made (CM) unibody conical endografts for saccular AAAs with narrow (≤20 mm wide) aortic bifurcation (AB) in three patients. Given the narrow AB, the option for a bifurcated stent graft was reputed not optimal. Therefore, we decided to further suggest the construction of a CM unibody conical stent graft with respect to unique anatomical characteristics of the patients. Technical success rate was 100%, and computed tomography angiography at first-month follow-up showed complete sealing proximally and distally with excellent conformability of the endografts in all the cases. All the patients were free from any-type endoleak (EL) and had no evidence of any endograft-related complication (i.e., fracture, thrombosis, or migration) or required any reintervention at their longest follow-up. We conclude that in the proper anatomic setting, the use of CM unibody conical endografts for elective EVAR of saccular AAAs with narrow AB is technically feasible with excellent short-term safety regarding ELs or migration.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
