The value of 3D TOF MRA in evaluation of anomalous vertebral artery in healthy adults
摘要
Abstract
Objective: To describe 3D-TOF MRA features of anomalous vertebral artery(VA) and evaluate its clinical significance in healthy adults who were accepted physical examination. Methods: A total of 442 cases in which 3D-TOF MRA was performed were retrospectively reviewed to discuss the incidence and relationship between VA origin and course variation. Results: Among this 442 cases, the incidence of origin variation was 4.75%(21/442) in which all cases were unilateral(19 cases in the left and 2 cases in the right). In these cases, the anomalous VA originated from the aortic arch or the right common carotid artery. All of the 21 cases with origin variation had the aberrant entrance position into the transverse foramen (4th or 5th). The incidence of abnormal entrance position into the transverse foramen was 9.50%(42/442),of which most cases(95.24%, 40/42)were unilateral. Of 40 cases, the incidence of both sides was the same(50.00%(20/40)). Conclusion: The VA origin variation always happened in the left side, and often combined with the course variation. 3D-TOF MRA plays an important part in the detection of the anomalous vertebral artery in healthy adults. It can provide useful information for the surgery and the therapy of related diseases.关键词
