Why the study?
Does the angiographic appearance of the carotid bifurcation differ among patients aged 50-59 with transient ischaemic attacks, completed stroke, or cerebral tumour?
Does the angiographic appearance of the carotid bifurcation differ among patients aged 50-59 with transient ischaemic attacks, completed stroke, or cerebral tumour?
Angiographic findings differ by cerebrovascular presentation, with carotid stenosis being more common in transient ischaemic attacks and carotid occlusion more common in completed strokes.
Suggests distinct carotid lesions by event type; hypothesis-generating and should not yet change practice.
The angiographic appearance of the carotid bifurcation was compared in groups of patients aged 50-59 suffering from transient ischaemic attacks (40 cases), cerebral infarction with completed stroke (44 cases), and cerebral hemisphere tumour (66 cases). Carotid occlusion was found in 14% of those with infarcts and 5% of those with transient ischaemic attacks. Carotid stenosis was found in 40% of those with ischaemic attacks and 14% of those with infarcts. Minor irregularity of the carotid arterial wall was equally common in all three groups.
