Spontaneous dissecting aneurysm of the renal arteries. A case and a review of the literature

Giant renal artery aneurysms: decision-making dilemmas

A case of a 10 cm giant renal artery aneurysm in an 81-year-old lady is herein reported. The patient presented as an incidental finding on an abdominal ultrasound with an aneurysm which was large, soft, egg-shell-like, and bilobular with a cauliflower-type pattern invading the parenchyma of the renal substance and extending caudally. A right nephrectomy was carried out, and the patient made an uneventful recovery. This paper reviews the options for treatment of giant renal artery aneurysms and highlights the benefit of a planned nephrectomy once there is adequate renal reserve in the opposite kidney using a midline approach for right-sided giant renal artery aneurysms and a left-sided flank approach for left-sided aneurysms.

The role of interventional radiology in the management of abdominal visceral artery aneurysms

Abdominal visceral artery aneurysms (VAA) include true and false aneurysms. The majority are asymptomatic and are discovered on cross-sectional imaging performed for unrelated clinical indications. With the maturation of techniques and devices used for embolization procedures and the treatment of aneurysms in other locations, most VAAs are now suitable for treatment by minimally invasive transcatheter techniques. The choice of technique used greatly depends on the local anatomy of the VAA and the experience of the interventional radiologist in complex vascular interventional techniques.
