An aneurysm is an abnormal bulging or weakness in the wall of an artery. Aneurysms can occur in the arteries supplying the kidneys and gut, and in arteries supplying the pelvis and legs. Aneurysms are typically asymptomatic and can enlarge over time. Risk factors include smoking and hypertension. Aneurysm rupture can be life threatening, but fortunately most can be repaired through minimally invasive endovascular techniques.
Aneurysm Embolization and Stent Placement
Vascular embolization is a minimally invasive procedure used to treat aneurysms that are at risk for rupture and bleeding. Using X-ray guidance, interventional radiologists navigate a catheter, or tiny tube, through the arteries to the aneurysm. The abnormal artery is then filled with small metal coils, blocking blood flow to the aneurysm and preventing the risk of rupture. In some cases, depending on the location of the aneurysm, a graft is used to create an internal bridge (stent) for blood flow, depressurizing the aneurysm and also preventing the risk of rupture.
Aortic Aneurysm Endograft Repair
Aortic Endograft Repair is a minimally invasive procedure that can be used to treat aortic aneurysms. Interventional radiologists insert endografts (stents covered with impermeable fabric) through a small puncture in the thigh. Under live X-ray guidance, the endografts are positioned to create an internal conduit, or bridge, for blood flow, thereby depressurizing the aneurysm and eliminating the risk of rupture.
