Endovascular Treatment of a Renocaval Arteriovenous Fistula Induced Inferior Vena Cava Aneurysm

摘要

Caval aneurysms are very rare but potentially lethal. Discussion about the need for treatment rises on individual basis. Based on the underlying etiology, a well-considered treatment plan should be made. Possible complications for invasive treatment and conservative management should be carefully weighed against each other. We present a patient with a caval aneurysm due to an arteriovenous fistula which we treated with endovascular embolization. Six months after treatment the patient is asymptomatic and the aneurysm size is decreased.
