Abstract
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.
Highlights
ID of the PCo-A refers to funnel-shaped widenings with a diameter less than 3 mm at the junction of the posterior communicating artery and the internal carotid artery [1,2,3]
Aggressive treatment is preferred for most patients presenting with hemorrhage [2,3,4,5,6], but little is known about the endovascular treatment of this condition
We report a case of ruptured ID of the PCo-A successfully treated by endovascular embolization
Summary
ID of the PCo-A refers to funnel-shaped widenings with a diameter less than 3 mm at the junction of the posterior communicating artery and the internal carotid artery [1,2,3]. ID of the PCo-A was regarded as normal anatomical variants with a low risk of rupture [4]. With increasing reports of ruptured ID of the PCo-A, bleeding is found to occur in cases of ID of the PCo-A. Aggressive treatment (i.e., surgical clipping) is preferred for most patients presenting with hemorrhage [2,3,4,5,6], but little is known about the endovascular treatment of this condition. We report a case of ruptured ID of the PCo-A successfully treated by endovascular embolization
