Stroke is defined as a focal neurological deficit of sudden onset due to a non-traumatic vascular lesion. Objective of this study is to study the prevalence of ischaemic versus haemorrhagic stroke in posterior circulatory stroke. To study the various risk factors in posterior circulatory stroke. To study the prognosis of patients with posterior circulatory stroke using glasgow coma scale at the time of admission. It was a prospective study. 50 clinical and imaging confirmed cases of posterior circulation strokes admitted to Medicine and Neurology departments in GGH, Kakinada are included. The diagnosis is confirmed by MRI/CT/MRA brain. A detailed Study of Clinical profile of each patient is done based on pre-designed protocol. Outcome was studied with reference to Glasgow Coma Scale score at the time of admission. In this study group 36 were male and 14 were female patients. The male to female ratio of stroke was 2.57:1 and both ischaemic and haemorrhagic strokes were more common in males. Stroke was more common in the middle aged and elderly. 70% of strokes are between age group of 51-70 years. The most frequent manifestation was motor dysfunction in 65.8% of ischaemic strokes and history of altered sensorium was 100% in haemorrhagic strokes. In ischaemic stroke the commonest risk factor was tobacco abuse (65.8%). But in the haemorrhagic strokes the commonest risk factors were hypertension (66.7%). GCS score showed an inverse relationship with the outcome. Patients with GCS score between 13-15 both in ischaemic and haemorrhagic stroke showed good outcome and recovered. Majority of the patients had ischaemic strokes. In ischaemic stroke the commonest risk factor was tobacco abuse. In the haemorrhagic strokes the commonest risk factors were hypertension. Patients with GCS score between 13-15 both in ischaemic and haemorrhagic stroke showed good outcome and recovered.
