Tratamiento de la hemorragia subaracnoidea aneurismática en el Hospital Clínico de la Universidad de Chile Translated title: Subarachnoid hemorrhage caused by intracranial aneurysms, experience in 82 patients

Translated abstract

Background: One third of patients with subarachnoid hemorrhage caused by intracranial aneurysms, die. Aim: Review of medical records of patients with subarachnoid hemorrhage treated at a clinical hospital. Material and Methods: Review of medical records of patients discharged from the hospital between 2006 and 2011 with the diagnosis of subarachnoid hemorrhage. Patients initially or subsequently treated elsewhere were not analyzed. Results: The medical records of 82 patients aged 24 to 100 years (77% females), were analyzed. The clinical diagnosis at the onset of the condition was correct in 82% of cases. In 95% of patients, an angiographic study and subsequent surgical intervention of the aneurysm were carried out within 24 hours of diagnosis. Global mortality was 23%. Twelve patients died prior to any possible treatment, due to the severity of the disease. Seventy six aneurysms in 70 patients were treated with clips or coils in 37 and 39 cases, respectively. Seven patients died. Forty seven patients had a Rankin disability score of two or less. Conclusions: The presence of an intracranial hematoma or acute hydrocephaly on admission and clinical vasospasm during evolution were associated with a bad prognosis.
