一位十三歲大的女孩於左前臂發現一腫塊,造成局部腫脹、壓痛並且無法做拇指的外展動作。經超音波檢查後,發現此腫塊具有典型的影像學特徵,因此診斷為靜脈血管畸形。在超音波導引下,我們對此病灶以經皮酒精注射的方式完成栓塞治療。此病患的症狀在治療後即得到緩解。在治療後八個月的追蹤中,此病灶的大小持續的下降,血流性也回復到正常基準。我們認為經皮酒精栓塞對於靜脈血管畸形所引起的症狀可以做有效的控制。
A 13-year-old girl had a venous malformation at her abdductor pollicis longus muscle of right forearm, with clinical presentation of local swelling, tenderness and inability to abduct her thumb. Under sonographic guidance, we treated this lesion with percutaneous intralesional ethanol injection. Her symptoms soon resolved after the treatment. In a follow-up period of 8 months, persistently decreased size of the lesion was observed without recurrence of symptom. We believe that US-guided ethanol injection is an easy, effective and safe therapy in relieving symptom associated with the venous malformation.
