Posterior Ischemic Optic Neuropathy

Background: The acute postoperative monocular vision loss following anterior communicating artery aneurysm clipping secondary to posterior ischemic optic neuropathy (PION) a rare presentation. Case Description: A 32-year old patient presented with a spontaneous holocranial thunderclap headache for 7 days, associated with vomiting. The SAH was diagnosed with a tiny saccular aneurysm arising from the anterior communicating artery. A left pterional craniotomy and clipping of aneurysm were done. On the 3rd postoperative day, he complained of left-sided complete blindness, and on the 5th postoperative day, his GCS dropped to E4V1M5 with right-sided hemiplegia. MRI brain showed normal optic apparatus with bilateral ACA and left MCA territory infarct. Conclusion: The PION must be kept in the differential diagnosis of post-clipping sudden visual deterioration, especially following anterior communicating artery aneurysm rupture.

Tuberculum Sellae

✓ This 70-year-old woman suffered a subarachnoid hemorrhage (SAH) from a ruptured anterior communicating artery aneurysm encased in a meningioma in the tuberculum sellae. Although preoperative magnetic resonance imaging disclosed that the aneurysmal complex was completely enclosed in the tumor, angiographic studies did not reveal arterial narrowing. The embedded aneurysm caused diffuse SAH rather than intratumoral hemorrhage. These factors indicated very little adhesion between the tumor and the encased arteries. Surgery was performed on the 20th day post-SAH. Intraoperative findings revealed that the tumor did not adhere to the enclosed vasculature except at the point of rupture of the aneurysm. The authors were able to clip the aneurysm safely after piecemeal removal of the tumor, which was finally extirpated without fear of aneurysm rupture. Careful stepwise procedures were essential to treat the aneurysm and the tumor simultaneously.

Rupture Site

AbstractComputational fluid dynamics (CFD) has been studied as a tool for the stratification of aneurysm rupture risk. We performed CFD analysis in a patient operated on for a ruptured anterior communicating artery aneurysm. The point of rupture was identified during surgery. The aneurysm and blood vessels were segmented from computed tomography angiography to prepare a model for simulations. We found that the streamlines showed a concentrated inflow jet directed straight at the rupture point, and high wall shear stress was found at the point of rupture in the aneurysm sac. Thus specific local hemodynamics may be indicative of the aneurysm rupture site.
