Abstract:
Cerebrovascular accident (CVA) is the most common cause of neurologic disorder accompanying grave prognosisand its mortality above 50%. Prior to introduction of the CT, the diagnosis have been depended on clinicalfindings and spinal puncture. Radiologic diagnostic methods, such as angiography, ventriculography andradioisotope scanning are invasive and less sentitive in diagnosis of CVA than CT. The size, location andextension of the intracranial pathology and ventricular penetration are accureately and rapidly portrayed by CT.Consequently, CT plays impotant role in effective tratement and evaluation of prognosis in CVA. Authors analyzed63 cases of diagnosed CVA who were performed CT scan in Korea General Hospital from November 1981 to April 1982.The results were as follows. 1. The most prevalent age group of CVA was 6th decade, and then 7th and 5th decadesin decreasing order. The sex ration between male and female was 1.2:1. 2. The causes of CVA were hypertensivehemorrhage (50.8%), vascular occlusive disease(22.2%), anurysm ruture (4.8%), arteriovenous malformation (3.2%)and hemorrhage of unknown etiology (19.0%). 3. The most common site of hemorrhage was basal ganglia (34.6%) andthen thalamus(21.8%) and cerebral lobes(20.5%). In infarction, the common sites were the lobes(64.7%) and thebasal ganglia (35.3%) 4. Round or oval shaped hematomas of high density (85.9%) were frequent findings ofhemorrhage and mass effect occured in 75.6%. 5. All infarctions were low in density ; Most of the lesion wasinhomogeneous(70.6%) and the rests were homogeneous. Mass effects were seen in 29.4%.
