经导管丝线线段混合明胶海绵颗粒栓塞治疗肢体高流量动静脉畸形的临床观察

Treatment of high flow arteriovenous malformations in the limbs with transcatheter embolization of silk segment and gelfoam granules

目的 探讨丝线线段混合明胶海绵颗粒血管内栓塞治疗肢体高流量动静脉畸形的效果.方法 对4例肢体高流量动静脉畸形患者,在数字减影血管造影下超选择性栓塞动静脉畸形病变血管.结果 超选择性栓塞动静脉畸形病变血管术后局部包快缩小,血管博动及病变区疼痛消失.术后追踪随访11～92个月,除1例25个月有复发外,其余3例均无复发.结论 经导管丝线线段混合明胶海绵颗粒栓塞治疗肢体高流量动静脉畸形安全有效.

Objective To evaluate the clinical effect and safety of transcatheter embolization of silk segment and gelfoam granules on treatment of high flow arteriovenous malformations （AVMs） in the limbs.Methods Four patients with AVMs were treated with superselective embolization of pathological arteriovenous vessels under digital subtraction angiography （DSA）.Results Immediate angiographic results showed the local mass decreased and vascular pulsation and pain disappeared.After 11 to 92 months following up,no recurrence of AVMs was observed by MRI or CT in all patients except for 1 patient with the right lower limb AVMs who developed a local mass caused by AVMs relapse at 25 months after embolization trentment.Conclusion For the high flow AVMs in the limbs,superselective transcatheter embolization with silk segment and gelfoam granules is an safe and effective treatment.
