Clinical Analysis of Prognostic Factors for Hypertensive Intracerebral Hemorrhage

ABSTRACT

The authors reviewed medical records of 219 patients who were admitted due to the hypertensive intracerebral hemorrhage(HICH) between January 1993 and December 1994. The relationship between the patient's age and sex, Glasgow Coma Scale(GCS) on the admission, location and volume of intracerebral hematoma, Graeb score, ventriculocranial ratio(VCR) and the maximum transverse diameter of fourth ventricle were analyzed. The neurological outcome for survivors was determined two years after admission. Forty normal brain scans were obtained to determine the normal range of VCR and the maximum transverse diameter of fourth ventricle. From reviewing the cases, the authors found; the most common age group of HICH was 7th and 8th decades with slight male preponderance(10.75); VCR of the lateral ventricle and maximum transverse diameter of the 4th ventricle were 0.16 and 1.14 cm in 40 normal brain scans, respectively; basal ganglia(42%) and thalamus(29.2%) were the most common sites of HICH hemorrhage in 219 patients followed by subcortex(13.7%), pons(7.3%) and cerebellum(4.6%); the fourth ventricular dilation(>1.35cm in diameter) and increased VCR(>0.24) were the most significant predictors for poor outcome.
