BackgroundEarly rebleeding after coiling of a ruptured intracranial aneurysm (IA) may cause disability or death. The incidence and predictors of early rebleeding have previously been sparsely investigated.PurposeTo assess the incidence and risk factors of early rebleeding after coiling of a ruptured IA and to analyze the outcome of the patients suffering early rehemorrhage.Material And MethodsThe data of 194 consecutive acutely (within 3 days) coiled patients with saccular ruptured IAs were analyzed. Age, gender, hypertension, aneurysm multiplicity, Hunt et Hess (HH) grade, intracerebral hematoma (ICH), intraventricular hematoma (IVH), external ventricular drainage (EVD), aneurysm location and size, and the grade of the initial aneurysm occlusion were tested to find the risk factors for early rebleeding. The outcome of the patients suffering rehemorrhage was verified.ResultsEarly rebleeding after coiling occurred in 7 patients out of 194 (3.6%). The presence of an ICH at admission and HH grade 3–5 before coiling were significant risk factors for rebleeding. An early rehemorrhage appeared as an enlargement of the initial ICH in all of these patients. Six of seven patients had good outcome (Glasgow Outcome Scale, GOS, 3–5). Logistic regression analysis did not find any other statistically significant risk factors.ConclusionThe incidence of early rebleeding after acutely coiled ruptured IA was 3.6%. Risk factors for post-procedural rehemorrhage were the presence of ICH on the initial CT and HH grade 3–5 before coiling. Early rebleeding appeared exclusively as an enlargement of the initial ICH and not an increased amount of blood in the subarachnoid space.
