Intravascular Sonography Assessment of a Type III Endoleak of an Aortic Endograft

Abstract

Abdominal aortic aneurysm (AAA) is a common disease in today’s older population. When AAAs grow large, the risk for rupture becomes high, and the AAA should be treated. It can be treated in one of two ways: open or endovascular repair. With endovascular repair, an endograft is placed within the aorta using angiographic guidance to exclude the AAA. Intravascular sonography (IVUS) can be used as an adjunct to angiography for the endovascular repair. The endograft must then be routinely followed for complications such as endoleak. This case report identifies a symptomatic type III endoleak and describes how IVUS is used in conjunction with computed tomography and angiography to treat type III endoleaks.
