Angiographic findings and clinical implications of persistent primitive hypoglossal artery.

Vlychou M, Georganas M, Spanomichos G, Kanavaros P, Artinopoulos C, Zavras GM - BMC Med Imaging (2003)

Bottom Line: BACKGROUND: The primitive hypoglossal artery (PHA) is a rare vascular anomaly, which belongs to the group of carotid-basilar anastomosis that may occur in adults.Additionally, the diagnostic alternatives for detection and assessment of PHA and the spectrum of diseases related to its presence are discussed.CONCLUSIONS: The presence of a persistent PHA can be recognized as an incidental finding in a cerebral angiography without any other clinical implication or may be associated with certain clinical entities such as aneurysm formation and atherosclerotic disease.

ABSTRACT
BACKGROUND: The primitive hypoglossal artery (PHA) is a rare vascular anomaly, which belongs to the group of carotid-basilar anastomosis that may occur in adults. CASE PRESENTATION: Herein is presented a case of a patient with a PHA, who had undergone a cerebral angiography due to investigation of subarachnoid hemorrhage. Additionally, the diagnostic alternatives for detection and assessment of PHA and the spectrum of diseases related to its presence are discussed. CONCLUSIONS: The presence of a persistent PHA can be recognized as an incidental finding in a cerebral angiography without any other clinical implication or may be associated with certain clinical entities such as aneurysm formation and atherosclerotic disease.

Figure 3: Catheterisation of the right vertebral artery, which appears hypoplastic.

Mentions: The angiography performed by Seldiger percutaneous puncture of the right femoral artery and selective catheterization of the right and left carotid artery and both vertebral arteries. There was no aneurysm or arteriovenous malformation demonstrated at this study. Instead, the selective catheterization of the left carotid artery disclosed a large persistent PHA originating from the internal carotid artery at the level of C2, which continued as basilar artery (Fig. 2). The catheterisation of the left subclavian artery demonstrated absence of the left vertebral artery whereas the right vertebral artery appeared hypoplastic (Fig 3). The right carotid artery appeared normal. Both posterior communicating arteries were visualised. The first angiogram in this particular patient did not reveal any vascular pathology. The patient repeated the angiography three weeks later, without any new other finding. Based on the findings of the two angiograms, the PHA was considered as an incidental finding and the etiology of the stroke in this patient was attributed to "nonaneurysmal" SAH.
