Distribution By Location of CT-Diagnosed Primary Intracerebral Hemorrhage In Isfahan
Abstract
Background: Intracerebral hemorrhage (ICH) is the third most frequent cause of stroke and accounts for 10 to 15 percent of all strokes in whites and 30 percent of them in blacks and Asian Population. The commoner sites of hemorrhages are different among populations and complications of them are different too.
Methods: In the present descriptive observational study, we studies 226 ICH patients admitted in Al-Zahra Hospital in Isfahan, Iran, from November 2001 to November 2003 and evaluated them for their symptoms and signs according to size and location of their hemorrhages recognized by CT-scan at the time of admission.
Results : From our 226 patients (126 men and 100 women ) , 38.5% of them had thalamic hemorrhage , 24% had lobar hemorrhage , 22.5% had putaminal hemorrhage , 8% had pontine hemorrhage , 6% had cerebellar hemorrhage, and 1.3% had internal capsular hemorrhage . Seizure was commoner in lobar and putaminal hemorrhages. Vomiting was present in 100% of cerebellar hemorrhage cases. Headache was present in 100% of cerebellar hemorrhage cases and between 66-83% of cases with hemorrhage cases in other sites. Coma was common in pontine hoemorrhage .
Conclusion: ICH accounts for 28.5% of our all stroke admissions.The incidence of intracerebral hemorrhage increases with age , reaching a maximum between the ages of 60 and 80 years old, and is higher in men than women and right side than the left side . We found that thalamic hemorrhage was the commonest site of hemorrhage among our patients second by lobar hemorrhage and more than half of our patients had headache or vomiting on the day of admission. Overall acute mortality rate depends mainly on the position and size of hemorrhage, which we can estimate them by the CT- scan. Diabetes mellitus is not considered as a risk factor, in contrast to hypertension.
