Abstract
- Ischemic stroke accounts for 70% to 80% of all strokes, but hemorrhagic stroke has greater fatality. For the information about the clinical features and distributions of each subtype of hemorrhagic stroke, we conducted a prospective investigation on all the cases of hemorrhagic strokes treated in Chonnam National University Hospital (CNUH) during the 18-month period since October 2002. We enrolled 456 patients with hemorrhagic stroke, which consisted of 219 intracerebral hemorrhage (ICH) and 237 subarachnoid hemorrhage (SAH). Among patients with ICH (male, 53.8%; mean age, 59.1+/-12.4), history of hypertension was found in 51.1% and diabetes in 10%. According to the anatomical locations of the hemorrhage, putamen (39.9%) was the most common site of ICH, followed by thalamus (27.4%), pons (12.8%), lobar (11.9%), cerebellum (6.4%) and caudate (2.3%). Intraventricular hemorrhage (IVH) was combined in 40.2% of the ICH cases. Among the onset symptoms of ICH, loss of consciousness (44.3%) was the most common, followed by paralysis (42.5%), nausea/vomiting (18.3%) and headache (16.9%). In SAH group (male, 40.9%; mean age, 57.7+/-11.9), history of hypertension was found in 40.1% and diabetes in 4%. Headache (58.4%) was the most common symptom of SAH, followed by nausea/vomiting (47.1%) and loss of consciousness (38.2%). SAH was found more common in women, whereas no sexual preference was detected with ICH.
