Abstract：Objective To analyze the magnetic resonance angiography(MRA) feature of persistent primitive trigeminal artery (PPTA) and to evaluate the utility of MRA in the diagnosis of this vascular anomaly. Methods 3D TOF MRA in 12 patients of persistent primitive trigeminal artery were retrospectively reviewed. Results In 12 cases of PPTA 7 cases occurred in the left side,5 cases in the right side. According to Saltzman classification,6 cases were type I,including 4 cases with anastomosis prox-imal basilar artery dysplasia,2 cases of basilar artery in normal development,1 patient with PPTA aneurysm;2 cases were type II,with anastomosis proximal basilar artery dysplasia;4 cases were type III,the left posterior cerebral artery was supplied by PP-TA in four patients,and the right posterior cerebral artery was supplied by the right posterior communicating artery,in which 3 ca-ses presented with anastomosis proximal basilar artery dysplasia,1 case with basilar artery in normal development. Conclusion 3D TOF MRA can clearly display and diagnose persistent primitive trigeminal artery,thereby providing the necessary vascular as-sessment for surgery.
