研究目的:

系统评估超声引导下微波消融治疗子宫肌瘤的中期(12个月)治疗效果,包括病灶体积缩小率、症状改善程度及并发症发生情况;并综合评估患者基线临床特征(如年龄、肌瘤类型、肌瘤数目)、常规超声参数(肌瘤大小、位置、血流信号)及动态超声造影强化特征(增强模式、灌注缺损区等),采用多因素回归分析明确影响疗效的关键因素,从而为个体化治疗方案的选择提供影像学依据,优化子宫肌瘤的治疗选择;同时平衡疗效、安全性以及患者需求等多方面因素,推动微创技术的精准应用,为患者提供更为安全、优质以及精准化的医疗服务。  

Objectives of Study:

This study systematically evaluates the mid-term (12-month) therapeutic efficacy of ultrasound-guided microwave ablation for uterine fibroids, including the lesion volume reduction rate, symptom improvement, and incidence of complications. It comprehensively assesses baseline clinical characteristics (e.g., age, fibroid type, number of fibroids), conventional ultrasound parameters (fibroid size, location, blood flow signals), and dynamic contrast-enhanced ultrasound features (enhancement patterns, perfusion defects, etc.). Multivariate regression analysis is employed to identify key factors influencing treatment outcomes, thereby providing imaging-based evidence for individualized treatment planning and optimizing therapeutic options for uterine fibroids. Additionally, the study balances efficacy, safety, and patient preferences to promote the precise application of minimally invasive techniques, ultimately delivering safer, higher-quality, and more personalized medical care to patients.

药物成份或治疗方案详述:

(一)术前评估 所有患者需在接受治疗前的1周内进行术前常规检查,检查项目包括:妇科超声、盆腔MRI、常规心电图、超声心动图、血常规、凝血常规、输血八项、肿瘤妇科八项等,以排除治疗禁忌症。 消融治疗前需进行超声造影和超声引导下子宫肌瘤穿刺活检。超声造影可以评估肌瘤的血流灌注情况,帮助确定肌瘤范围;术前活检可以明确病理性质,避免对恶性病变误行消融治疗。 (二)超声引导下经腹子宫肌瘤微波消融术 治疗前禁食禁水6h,有严重便秘者可服缓泻剂导泻清理肠道。治疗前半小时插导尿管(夹闭)。需监测心率、血压、血氧饱和度等。麻醉方法为静脉清醒镇痛麻醉,必要时可采用硬脊膜外腔麻醉辅助穿刺点局部皮下0.1%利多卡因麻醉。 消融前,将0.9%生理盐水注入腹腔以产生人工腹水,旨在将子宫与邻近的关键器官(如膀胱、肠道和主要血管)分开。只有当病灶靠近皮肤并且穿刺路线可以完全避开这些器官时,才省略此步骤。随后,将微波针通过腹壁插入目标肌瘤的深部,微波针尖端位于距离肌瘤远端边缘0.5 cm的位置,以防止对子宫外组织的热损伤。消融手术采用杠杆撬离和移动消融等技术,从后到前逐层进行。初始消融以50W功率进行180秒。然后将微波针逐渐撤回2 cm以进行后续消融,直到消融期间产生的高回声云覆盖该部分的浅表部分。当微波针尖端接近肌瘤的深缘时,调整穿刺角度以使针头重新进入肌瘤,重复上述消融方案。在整个消融过程中,对肌瘤和微波针位置进行实时超声监测。消融后超声造影评估消融是否完全,若不完全则术中即刻补充消融。 消融结束,确认微波辐射停止,拔出微波针,清洁穿刺点皮肤,局部加压包扎。观察导尿管流出的尿液颜色,观察患者生命体征是否平稳。嘱患者禁食4h,卧床休息24h,保留心电监护4h,予抗生素预防感染、抑酸护胃、止痛、补液等对症治疗。 不良反应的处理: (1)疼痛:大部分患者可耐受,8h内可自行缓解,无需用药,个别患者需对症治疗。 (2)阴道排液:黏膜下子宫肌瘤消融后患者可出现阴道排液,呈淡粉色,多在1~2周内自行消失。 (3)恶心:可对症处理,可通过缩短麻醉时间来预防。 (4)宫腔(盆腔)或治疗区感染:严格掌握无菌的宫腔内侵入性操作,消融后应用抗生素预防感染。治疗后嘱患者1个月内避免性交和公共场所盆浴。 (5)肠道损伤:治疗后密切观察,如有肠道直接热损伤的证据应及时抗炎治疗及外科处理。
