- Abstract
We describe a case of a right broad-necked posterior communicating artery (PcomA) aneurysm with a fetal posterior cerebral artery (PCA) incorporated in the aneurysm neck. We performed waffle cone stent-assisted coiling and achieved almost complete occlusion of the aneurysm. At 18-month follow-up angiography, the aneurysm was recanalized and further coiling was needed. The same waffle cone method of coiling might be expected to produce the same unsatisfactory results on follow-up, so we decided to use retrograde stent navigation and placement through the anterior communicating artery (AcomA) from the contralateral internal carotid artery (ICA) to the ipsilateral ICA and fetal PCA. The stent delivery microcatheter from the contralateral ICA could not be introduced in the AcomA. So 2mg nimodipine was infused through the stent delivery microcatheter to the AcomA and the stent delivery microcatheter was passed through the AcomA easily and could be navigated to the ipsilateral A1, ICA, and to the fetal PCA. With this additional stent, the aneurysm was completely separated from the fetal PCA and ICA. Further coiling could be performed safely through the microcatheter in the ipsilateral ICA. The patient had stable aneurysm occlusion at the six-month follow up.
