CT scanning and prognosis in patients with hypertensive intracerebral hemorrhage:a retrospective analysis

Abstract

Objective To investigate the relationship between CT scanning results and clinical prognosis in patients with hypertensive intracerebral hemorrhage(HICH) and to provide clinical evidence for recurrence, stroke prevention, and the management of high risk HICH people. Methods The data of 425 patients (male 269, female 156) with HICH admitted to our hospital from January, 2000 to December, 2004 were collected and the relationships among bleeding locations, volumes of bleeding, age, gender and their prognosis were examined. These data were analyzed with SPSS 10.0 software. Results In all patients with HICH, supratentoriai intracerebral hemorrhage (SICH, 87.53%) was mainly showed with an average volume of bleeding of (30.042±27.905) ml and 39 death (10.5%);infratentorial intracerebral haemorrhage (IICH, 8.94%) appeared with an average volume of bleeding of (7.838±5.761) ml and 2 death (5.3%). As to bleeding location, the basal ganglia ranked first (65.65%), the lobe of brain accounted for 20.71% and following ones were the brain stem (6.12%), the ventrieular system (3.29%), the cerebellum (2.82%), the corona radiate (0.71%), the corpus eallosum (0.47%) and multi-site hemorrhage (0.24%). Bleeding locations significantly differed among different age groups (X =22.080, P=0.001). Conclusions Mortality of HICH is higher in patients with SICH than that in patients with IICH. Volume of bleeding is one of the most important risk factors and 40 mL is the maximum bleeding. The more volume of bleeding is;the higher mortality is. Morbility and age are positively correlative, while younger group have significantly higher morbility of IICH than elder group because their circuitous and dilated vertebral artery may be a kind of protective mechanism which can reduce the development of HICH to some extent. Early CT scanning can note bleeding location and volume of bleeding, and then help to determine proper treatment and predict clinical prognosis.
