Endoport-Assisted Microsurgical Treatment of a Ruptured Periventricular Aneurysm

Figure 1

Cerebral angiography, (a) lateral and (b) AP projections of a right internal carotid artery injection and (c) lateral projection of a right vertebral artery injection, shows an aneurysm (arrowhead) arising from the medial posterior choroidal artery branch of the right posterior cerebral artery, with stagnation of contrast in the late arterial phase. Preoperative CTA, (d) axial, (e) sagittal, and (f) coronal views, shows a 5 × 4 × 3 mm periventricular aneurysm (arrowhead), projecting into the atrium of the right lateral ventricle with multiple adjacent collateral vessels.
