Paravisceral Abdominal Aortic Aneurysm Risk Factors for Mortality Following Open Repair

Purpose: To identify a patient with a paravisceral abdominal aortic aneurysm who may benefit from an endovascular repair based on the study of Gupta et al.

Description

Gupta et al identified risk factors for mortality following an open repair of a paravisceral abdominal aortic aneurysm. These can help to identify a patient who may be a candidate for endovascular repair with a fenestrated or branched stent graft. The authors are from Creighton University and the University of Nebraska.


 

A paravisceral aortic aneurysm may affect the origin of:

(1) one or both renal arteries

(2) a mesenteric artery

 

The 30-day mortality rate after open repair was 4.5%.

 

Risk factors for mortality following open repair:

(1) female gender

(2) peripheral arterial disease (PAD) requiring revasuclarization and/or amputation

(3) COPD

(4) prolonged anesthesia time (odds ratio 1.004 per minute; at 3 hours the odds ratio is 2.05)

 

The presence of one or more of these risk factors may justify an endovascular procedure.
