Randomized Controlled Trial Comparative StudyEffect of temporary clipping on frontal lobe functions in patients with ruptured aneurysm of the anterior communicating artery.
After surgery for ruptured anterior communicating artery (ACoA) aneurysm, several patients who have achieved a favorable neurological outcome yet have been observed to suffer from a poor cognitive outcome. The aim of this study was to explore the possible effects of temporary clip applications on frontal lobe functions in the patients with ruptured ACoA aneurysm. ⋯ The results emphasize that the negative effects of temporary vessel occlusion on cognitive changes occur before ischemic damage. Thus, such negative effects of temporary clipping on cognitive functions should not be neglected by surgeons during surgery.
