Five patients with painful vascular malformations of the extremities that were refractory to standard treatment and were confirmed as low-flow malformations on dynamic contrast-enhanced magnetic resonance (MR) imaging were treated with MR imaging-guided high intensity focused ultrasound. Daily maximum numeric rating scale scores for pain improved from 8.4 ± 1.5 to 1.6 ± 2.2 (P = .004) at a median follow-up of 9 months (range, 4-36 mo). The size of the vascular malformations decreased on follow-up MR imaging (median enhancing volume, 8.2 mL [0.7-10.1 mL] before treatment; 0 mL [0-2.3 mL] after treatment; P = .018) at a median follow-up of 5 months (range, 3-36 mo). No complications occurred.
5例四肢疼痛性血管畸形患者，对标准治疗无效，动态对比增强磁共振成像（MR）证实为低流量畸形，采用MR引导下高强度聚焦超声治疗。在中位随访9个月（范围4 - 36个月）时，每日疼痛数字评定量表最高得分从8.4±1.5改善至1.6±2.2（P = 0.004）。在中位随访5个月（范围3 - 36个月）时，随访MR成像显示血管畸形大小减小（治疗前中位强化体积为8.2 mL [0.7 - 10.1 mL]；治疗后为0 mL [0 - 2.3 mL]；P = 0.018）。未发生并发症。
