Abstract:
Branches of the extracranial internal carotid artery are very rare. A case is reported wherein an aberrant artery originated from the bulb of the internal carotid artery (ICA) approximately 2 cm from the bifurcation. The ICA was occluded distal to the branch's origin. Arteriography in this case gave the appearance of a carotid "string sign". Vascular surgeons and radiologists should be aware of this anomaly when interpreting carotid arteriograms.
