脑动静脉畸形的血管造影诊断

Angiographic diagnosis of cerebral arteriovenous malformations

目的 加深对脑动静脉畸形的血管造影表现特点的认识,探讨其诊断价值。方法 回顾性分析98例脑动静脉畸形的选择性动脉造影资料,由两名医生对其DSA表现进行动态观察、共同分析,并达成一致意见。结果 DSA均可显示供血动脉、畸形血管团和引流静脉,获得明确的诊断。98例脑AVM中,病灶最大直径4 0cm以下者57例,位于深部4 6例,单支供血动脉1 7例,深部引流1 6例,单支引流静脉37例。结论 DSA检查是脑动静脉畸形合理而可靠的诊断方法,有利于估计其预后并制订治疗方案。

Objective To make a futher understanding of DSA appearances of the cerebral arteriovenous malformations and to evaluate the clinical value of DSA diagnosis of it. Methods Ninety-eight patients with cerebral arteriovenous malformations(AVMs) underwent selective angiography were analyzed retrospectively. The DSA appearances in all of the patients were observed dynamically in a double blind method by two experienced radiologists together and formed a consensus interpretation. Results Of the 98 patients who underwent selective DSA, the supplying artery, nidus and draining veins were clearly shown. Among the 98 cases, the greatest diameter were less than 4.0 cm in 57 cases, the central location in 46 cases, the single supplying artery in 17 cases, the deep draining vein in 16 cases and the single draining vein in 37 cases. Conclusion DSA is one of the ideal and reliable diagnoses methods,and it is very important to assess the prognosis and to work out the therapy plan.
