Early angiographic occlusion of ruptured blister aneurysms of the internal carotid artery using the Pipeline Embolization Device as a primary treatment option

Abstract

Background: Data on the timing, durability and occlusion rate of treating ruptured blister cerebral aneurysms using the Pipeline Embolization Device (PED) are limited.

Clinical presentation: Three patients who presented with subarachnoid hemorrhages from ruptured blister aneurysms of the internal carotid arteries were treated with the PED.

Results: Aneurysmal occlusion with reconstruction of the parent vessels occurred angiographically using the PED as a primary treatment modality. All three patients were treated successfully without immediate or delayed complications and remained neurologically intact during the 6-month follow-up period.

Conclusions: Complete occlusion of a ruptured blister aneurysm can occur immediately after PED placement. In ruptured blister aneurysms with contrast stagnation after PED treatment, early angiographic occlusion was confirmed as early as 6 weeks and continued with medium-term durability.
