Accuracy of CT angiography in detection of blood supply dominance of posterior cerebral artery in patients with posterior communicating artery aneurysm

There are many potential anatomical variations in the connection between the internal carotid artery and the posterior circulation through the posterior communicating artery (PCoA). We describe the endovascular treatment of an aneurysm arising near the origin of the PCoA belonging to a transitional type posterior cerebral artery. Coil embolization subsequently resulted in thrombo-occlusion of the adjacent PCoA causing thalamic infarction even though sufficient retrograde flow had been confirmed pre-operatively by Allcock's test.

The authors report a case of a posterior cerebral artery aneurysm arising from an aberrant arterial branch that was found to be splitting the oculomotor nerve. This 63-year-old man presented with headaches, and CT imaging revealed subarachnoid hemorrhage primarily within the basilar cisterns. Formal angiography and CT angiography revealed a saccular aneurysm arising from the posterior cerebral artery. Intraoperatively, the third cranial nerve was found to be fenestrated with the artery and aneurysm.

Contralateral Internal Carotid Artery

Treatment of recurrent ruptured aneurysms incorporating a branch vessel arising from the dome is challenging. Here, we attempted horizontal stent-assisted coil embolisation via a retrograde route from the contralateral internal carotid artery to treat a small ruptured posterior communicating artery aneurysm incorporating a foetal variant posterior cerebral artery after clipping.
