Cerebrovascular accident pattern and distribution of different types based on computed tomography

ABSTRACT

This study was undertaken to determine the pattern and distribution of various types of C. V.As in 110 patients who underwent C.T. for suspected C.V.A. The percentage of all C.V.A. by pathological type was Ischaemic cerebral infarction [I.C.I.] 55.4% localized primary intracerebral haemorrhage [P.l.C.H.] - 37.3% generalized subarachnoid haemorrhage [S.A.H.] 5.5% and cerebellar haematoma 1.8%. Right side was affected in 33 patients [30%] and left in 52 [47.2%]. Seventeen patients [14.6%] had multiple areas involved. It was also noted that ischaemic stroke was common in older age group [70-85%]. The most common area of brain involved for all types of C. V.A. was internal capsule and basal ganglia 31 [28.1%] followed by parietal region 17 [15.4%]. frontal region 7 [6.36%], frontotemporal 3 [2.7%], frontoparietal 12 [10.9%], temporal 4 [3.6%], temporoparivtal 10 [9%], parietooccipital 8 [7.2%] and occipital 2 [1.8%]. We recommend C.T. scan of all patients with C.V.A. for proper assessment. A national project to determine its incidence, risk factors, pattern and complications should be undertaken
