Persistent hypoglossal artery: An anomaly leading to false-positive carotid duplex sonography

Ann Vasc Surg. 1992 Mar;6(2):176-8. doi: 10.1007/BF02042743.

Abstract

Duplex ultrasonography is becoming increasingly popular as the sole diagnostic test in the evaluation of carotid artery bifurcation disease. We present a patient with a persistent hypoglossal artery, a rare primitive internal carotid-basilar anastomosis, masquerading as an internal carotid artery stenosis on ultrasound. The operative management of this anomaly is reviewed.
