颈动脉假性动脉瘤的DSA诊断

目的:加深对颈动脉假性动脉瘤DSA表现特点的认识,探讨其诊断价值。方法：由两名有经验的放射学医师对16例颈动脉假性动脉瘤的血管造影及临床资料进行同顾性分析。结果：16例患者经DSA检查均能明确诊断,其中颈总动脉者1例,颈动脉分叉处9例,颈内动脉5例,颈外动脉1例。DSA主要表现为：所有瘤腔内造影剂滞留,瘤腔内形成涡流者12例,动脉瘤开口处“喷射征”17例,颈动脉分叉角度增大,颈内、外动脉移位者12例。结论：DSA是诊断颈动脉假性动脉瘤最有价值的检查方法,它有利于临床治疗方式的选择。

DSA Diagnosis of the Carotid Artery Pseudoaneurysm

Objective: To make a further understanding of the DSA features of the carotid artery pseudoaneurysm (CAPA) and to explore the clinical value of DSA diagnosis of it. Methods: Sixteen eases of CAPA with clinical and angiographic data were analyzed retrospectively. The DSA appearances in all of the patients were observed dynamically by two experienced radiologists together and formed a consensus interpretation. Results: DSA can establish definitive diagnosis in all cases. The parent artieries included the common carotid artery (1 case), common carotid artery bifurcation (9 cases), internal carotid artery (5 cases) and external carotid artery (1 case). The DSA features of the CAPA were: the contrast media retained in the aneuysm in all cases; the aneuysm lumen with turbulent flow in 9 cases; the "jetting sign" at the leak of the parent artery in 7 cases; increase of bifuraction angles of internal and external carotid arteries in 12 cases. Conclusion: DSA is the most valuable examination method in diagnosis of CAPA, and it can not only make definitive diagnosis, but also play an important role in selection of therapeutic planning.
