Hemodynamic Infarction Associated with Coil Embolization of Intracranial Aneurysm / 대한뇌혈관외과학회지

ABSTRACT

We report a case of borderzone infarction which was developed after the coil embolization of unruptured internal carotid-posterior communicating artery aneurysm. Post-procedural angiography and brain computerized tomographic scan did not reveal any abnormality. However, brain magnetic resonance image (MRI) showed a wedge-shaped borderzone cerebral infarction between left middle cerebral artery and left anterior cerebral artery territory. It was suspected to be a manifestation of hypoperfusion in the internal carotid artery territory, caused by hemodynamic instability during the procedure. In order to prevent this unexpected serious complication, using the continuous hemodynamic monitoring during aneurysmal coil embolization, such as transcranial doppler ultrasonography, should be considered.
