Analysis of the impact of intraventricular hemorrhage on the functional outcome of ruptured anterior cerebral artery aneurysm after clipping

Abstract

Various clinical symptoms and variables have been suggested as potential indicators of outcomes in patients with subarachnoid hemorrhage (SAH) resulting from ruptured intracranial aneurysms. The detailed discussion of the consequences of intraventricular hemorrhage (IVH), frequently reported in cases of anterior communicating artery (ACoA) aneurysms, is still pending. The study aimed to assess the results of aneurysm surgery performed early versus delayed in patients with SAH, specifically focusing on the occurrence of IVH. This study involved patients with ACoA aneurysms who experienced SAH and underwent microsurgical clipping of the aneurysm. A retrospective review was conducted on the patients’ medical records. The modified Rankin score was compared between two groups of patients based on the presence or absence of IVH. Ninety-one participants (52 males and 39 females) were included in the study. The initial computed tomography scan showed that 20 patients (with a mean age of 51 ± 13.7 years) had IVH, while 71 patients (with a mean age of 45.8 ± 11.7 years) did not have any signs of IVH. The proportion of patients with poor functional outcomes after six months was 55% in the presence of IVH, compared to 25.4% in patients without IVH, indicating a significant difference in outcome between the two groups (P < 0.016). Patients with SAH having aneurysms located in the ACoA associated with the intraventricular hemorrhage had a poor functional outcome.
