超声引导下经皮微波消融治疗恶性胸、腹壁肿瘤

目的 观察超声引导下经皮微波消融（MWA）治疗恶性胸、腹壁肿瘤的效果。方法 对11例恶性胸、腹壁肿瘤患者行超声引导下经皮MWA治疗，共治疗14个病灶，腹壁6个，胸壁8个；术后随访，观察治疗效果及不良反应。结果 11例超声引导下MWA治疗均成功，技术成功率100%。术后1个月8例治疗有效，3例肿瘤残存。2例术后出现局部疼痛，经对症治疗后缓解；1例局部脂肪液化，予局部消毒换药1个月后痊愈。未见气胸、肠道损伤、皮肤烧伤等严重并发症。4例术前合并病灶周围神经痛，术后疼痛得到有效控制。术后随访4~28个月，中位随访时间8个月；期间2例失访、2例死亡；至随访终点7例疗效较好，未见复发及转移。结论 超声引导下经皮MWA治疗恶性胸、腹壁肿瘤安全、有效。

Ultrasound-guided percutaneous microwave ablation for malignant thoracic or abdominal wall tumors

Objective To observe the effect of ultrasound-guided percutaneous microwave ablation (MWA) for treatment of malignant thoracic and abdominal wall tumors. Methods Ultrasound-guided percutaneous MWA was performed in 11 patients with malignant thoracic or abdominal wall tumors. There were a total of 14 tumors, 6 at the abdominal wall and 8 at the chest wall. Postoperative follow-up was performed to observe the therapeutic effect and adverse reactions. Results All 11 patients were successfully treated with ultrasound-guided MWA, and the technical success rate was 100%. One month after ablation, effective treatment was observed in 8 cases, while remained tumors were found in the rest 3 cases. Local pain after ablation occurred in 2 patients, which relieved after symptomatic treatments. Local fat liquefaction occurred in 1 patient, which was healed after local disinfection and dressing change for 1 month. No severe complications such as pneumothorax, intestinal injury and skin burn occurred. The pains were effectively controlled in 4 patients with peripheral neuropathic pains. The patients were followed up for 4-28 months, with a median follow-up time of 8 months, during which 2 cases were lost to follow-up and 2 cases died. At the end of follow-up, good effect was observed in the remaining 7 patients, while no recurrence or metastasis was found. Conclusion Ultrasound-guided MWA was safe and effective for local treatment of malignant thoracic or abdominal wall tumors.
