Transcatheter Arterial Embolization for Impending Rupture of an Isolated Internal Iliac Artery Aneurysm Complicated with Disseminated Intravascular Coagulation

A 90-year-old male, with impending rupture of an isolated internal iliac artery aneurysm (IIAA) complicated with disseminated intravascular coagulation (DIC) was successfully treated with transcatheter arterial embolization (TAE). After TAE, enlargement of the aneurysm was arrested and coagulation-fibrinolytic abnormalities induced by DIC improved without severe complications. Although IIAA is relatively rare, the post-operative mortality of patients with ruptures is reportedly high. We assessed the usefulness of this procedure for impending rupture of IIAA, especially for patients in high risk groups.(Internal Medicine 38: 27-30, 1999)
