Recurrent rupture of a hypogastric aneurysm caused by spontaneous recanalization of an Amplatzer vascular plug.

A patient with a ruptured hypogastric aneurysm was treated via an endovascular approach with coils in the outflow vessels and an Amplatzer vascular plug (AVP) in the main trunk. After 4 weeks, the patient was readmitted with a recurrence of rupture of the hypogastric aneurysm caused by recanalization of the AVP. Final occlusion of the hypogastric artery was achieved by placement of a stent-graft and additional coils. In consideration of this experience, it is recommended that additional coils or several AVPs be used and early contrast medium-enhanced computed tomography follow-up be performed.
