Differential Flows in the Aortic Graft following Open Surgery of Infra-renal Aortic and Iliac Aneurysm

Vikas Deep Goyal, Rajkumar Sharma, Shelly Rana, Saurabh Sood.


We present a case of combined abdominal and iliac artery aneurysm in 60-year-old male patient who previously had
undergone bilateral below knee amputation of both legs due to embolization and subsequent gangrene. Patient was a chronic
smoker and was also suffering from hypertension. Computed tomographic (CT) angiogram showed large aneurysm of
the infrarenal aorta and right common iliac artery. Surgical intervention in the form of aneurysmorrhapy and aorto-biiliac
grafting was done using 20 mm × 10 mm knitted gelatin impregnated bifurcation Dacron graft. The patient recovered
well and was discharged after 10 days, post-operative CT angiogram done after 1 month showed difference of contrast
enhancement in the anterior and posterior aspects of the graft, probably due to differential flows, turbulence, and stasis
and thereby increasing the risk of graft thrombosis.

Key words: Aneurysmorrhapy, aortic aneurysm, aorto-biiliac grafting, differential flows, iliac artery aneurysm, open surgery
