Anterior Choroidal Artery Syndrome occurring after endovascular coiling Treatment : Report of Two Cases / 대한뇌혈관외과학회지

ABSTRACT

Anterior choroidal artery (AChA) syndrome is widely known to be composed of a triad of hemiparesis, hemisensory loss and homonymous hemianopia. AChA syndrome is an unusual complication of aneurysmal treatment. This report documents two cases of AChA syndrome that occurred after an endovascular aneurysmal coiling procedure. Both cases showed complete recovery of the neurologic deficit at the time of discharge. To avoid this complication, meticulous caution is required to preserve the posterior communicating artery, the AChA and the various perforators during an endovascular procedure. When AChA syndrome occurs, immediate treatment is necessary, including vasodilators, thrombolytics and close observation of the patient's clinical status.
