Endovascular Embolization of Ruptured Infundibular Dilation of Posterior Communicating Artery : A Case Report

Abstract EN

Hemorrhage due to the rupture of the infundibular dilatation of the posterior communicating artery (ID of the PCo-A) occurs infrequently.

The preferred treatment of such hemorrhages is surgical clipping through craniotomy.

There are few reports about endovascular coil embolization in such cases.

We report such a case treated by endovascular embolization.

A 35-year-old man, who had experienced 2 episodes of subarachnoid hemorrhage (SAH), was found to have a ruptured ID of the PCo-A by head computed tomography angiography (CTA) and digital subtraction angiography (DSA).

We performed stent-assisted endovascular coil embolization through a combined anterior and posterior circulation approach.

Postembolization angiography showed absence of contrast filling of the ID of the PCo-A and nonleakage of the contrast agent.

The patient recovered well with no complications.

SAH recurrence was not recorded during the 1-year followup.

The postoperative angiographic result was good.

To our knowledge, this is the first case of hemorrhage due to ruptured ID of the PCo-A that was treated by such a technique.
