Epidemiological characteristics and causes of death after Aneurysmal Subarachnoid Hemorrhage – SAH

Abstract

This study analyzed the epidemiological characteristics and causes of deaths after SAH in patients admitted to a referral hospital in southern Brazil. A hospital database was used, comprising the years 2006-2018, composed of 148 patients. Cross-tabulations and Logistic Regression were performed to determine the odds of death of epidemiological characteristics. Ruptured aneurysms had a higher incidence in women, aged between 41 and 60 years. Headache is the predominant symptom in 95% patients. Hypertension (61%) and smoking (47%) are the prevalent risk factors. The age group with the highest frequency of deaths is 71 to 80 years old. The causes of death are: external ventricular shunt (34%), ischemic injury (9%), bleeding (7%), cerebral edema (8%), sepsis (28%) and pneumonia (24.3%). Knowing the risk factors and complications involved provide important insights that help in understanding their genesis, treatment and prevention.
