Profile of extracranial cerebrovascular disease in Kelantan: a study by continuous wave Doppler ultrasonography.
The present study outlines the clinical profile and patterns of extracranial vascular abnormalities detected by continuous wave doppler ultrasonography (CWDU) in 100 patients with cerebrovascular insufficiency states. Males outnumbered females (65:35); completed stroke (CS) was a more common mode of presentation than transient ischaemic attacks (TIA); carotid strokes were more common than vertebro-basilar ones; and hypertension was the most common predisposing factor. The CWDU evaluation revealed extracranial vascular disease in 73% of patients. Vascular occlusions were more common in patients with TIA. Overall, 33% of the patients had evidence of proximal obstruction of the cerebral vessels below the neck. The clinical prediction of vascular territory (carotid or vertebro-basilar) matched with the findings on CWDU, but evidence of subclinical multiple-vessel involvement could be detected in 48% of the patients.
