Abstract

To report a disconnection between the bare suprarenal stent and the main body of a Zenith endograft. A 79-year-old man with a history of successful endovascular repair of an aortic aneurysm presented a sudden episode of hypotension and hematuria. He had undergone implantation of a Zenith bifurcated device 8 years earlier in 2006. Plain abdominal radiography and computed tomography showed disconnection of the uncovered proximal stent, which led to endograft migration and type Ia endoleak. The patient also presented with distal endoleaks at the attachment sites in both common iliac arteries. The aneurysm sac diameter had increased from 52 to 96 mm. A proximal aortic cuff and bilateral iliac extensions were deployed via a common femoral artery access. Completion angiography did not show endoleak. After publication of a few such cases with the older Zenith device, the union between the suprarenal stent and main body was reinforced in 2002 to prevent this complication. Since modification of the device, this sequela had not been described. The reappearance of this complication underscores the need for continued surveillance, considering that these late events may require a reintervention to maintain the clinical success of the proced...Continue Reading

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.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm 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.

Aneurysm

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