Question

Quizplus · Accepted Answer

A systolic bruit over the carotid artery is almost diagnostic for an arteriovenous malformation. The bruit is caused by blood flowing through the abnormal connection between arteries and veins in the malformation. Other clinical findings may be present, but the bruit is a strong indicator. Decreased level of consciousness and hypertension with bradycardia are not specific to arteriovenous malformations, and a diastolic bruit over the temporal artery may indicate temporal arteritis, but not arteriovenous malformations.
