Anomalous External Carotid Artery-Internal Carotid Artery Anastomosis in Two Patients with Proximal Internal Carotid Arterial Remnants.

Kim CH, Cho YD, Kang HS, Kim JE, Jung SC, Ahn JH, Han MH - Korean J Radiol (2015)

Bottom Line: The ICA remnant of one patient (identifiable immediately upon bifurcation of the common carotid artery) was hypoplastic, and that of the other patient was an occluded arterial stump.These features are not typical of non-bifurcating ICA.The occipital artery originated from an anomalous connection in one instance and from the main trunk of the ECA (just past the ECA-ICA connection) in the other.

ABSTRACT
Two angiographic instances of anomalous external carotid artery (ECA) and internal carotid artery (ICA) anastomosis are described, each occurring at the C2-3 level and bearing remnants of proximal ICA. The ICA remnant of one patient (identifiable immediately upon bifurcation of the common carotid artery) was hypoplastic, and that of the other patient was an occluded arterial stump. These features are not typical of non-bifurcating ICA. The occipital artery originated from an anomalous connection in one instance and from the main trunk of the ECA (just past the ECA-ICA connection) in the other.

Mentions: A 60-year-old male was admitted to further evaluate a cerebral aneurysm incidentally discovered by an MRA during a medical check-up. Diagnostic angiography showed a right middle cerebral artery (MCA) bifurcation aneurysm, roughly 3 mm in size, with an anomalous left ECA-ICA anastomosis at the C2 level. At the C4 level, an arterial stump of the ICA was evident (Fig. 2). The occipital artery originated from the ECA main trunk, just past the anomalous connection. Surgical clipping of the right MCA bifurcation aneurysm was elected.
