Abstract
Objective: In this report, a case with a true posterior communicating artery aneurysm that showed rapid growth and repetitive recanalization after coiling and that was successfully obliterated using a double-microcatheter technique via two different routes is presented.
Case: A 52-year-old woman who had undergone a coil embolization for a ruptured, saccular aneurysm arising at a non-branching site of the left posterior communicating artery two months previously presented with the sudden onset of a headache. A CT scan revealed a subarachnoid hemorrhage, and cerebral angiography showed recanalization in association with the rapid growth of the aneurysm. The aneurysm continued to grow despite two additional coil embolizations. Finally, the aneurysm was successfully embolized using coils through two microcatheters navigated via the ipsilateral internal carotid artery and the left vertebral artery.
Conclusion: This is the first report of coiling using the double-microcatheter technique via two distinct routes. This method is a safe and effective treatment option for true posterior communicating aneurysms.
