本文报告44例臂丛神经撕脱后继发疼痛患者行背侧入路区(DREZ)毁损术的远期疗效，平均临床随访时间63个月。术后镇痛效果由患者判断为良(疼痛减少75%以上)、一般(疼痛减少25%~75%)或较差(疼痛减少0~25%)。根据这些标准，35名患者(77%)在最后一次随访时疼痛持续良好(30例，68%)或可(5例，11%)。8例(18%)有持续性的神经功能障碍，尽管这些通常是轻微的。DREZ热凝术是一种有效的缓解去传入疼痛的方法。术后早期产生的止痛作用似乎可以长期维持。
The long-term results of 44 patients who underwent dorsal route entry zone (DREZ) lesioning for pain secondary to brachial plexus avulsion are reported with a mean clinical follow up period of 63 months. The postoperative analgesic effect was judged by the patients as being good (greater than 75% pain reduction), fair (25-75% pain reduction), or poor (0-25% pain reduction). With these criteria 35 patients (77%) had continuing good (30 cases, 68%) or fair (five cases, 11%) pain relief at the time of final follow up. Eight cases (18%) had persisting neurological deficits, although these were generally mild. DREZ thermocoagulation is an effective procedure for relieving deafferentation pain. The analgesic effect which is produced in the early postoperative period seems to be maintained in the long-term.
