子宫动脉甲氨蝶呤灌注和栓塞治疗子宫腺肌病

Uterine arterial methotrexate infusion and embolization in the treatment of uterine adenomyosis

目的探讨DSA引导下经导管子宫动脉内灌注甲氨蝶呤结合子宫动脉栓塞治疗不同类型子宫腺肌病的临床疗效。方法对33例根据临床症状、彩色B超初筛,在Seldinger方法完成子宫动脉超选择性插管造影,证实为弥漫型子宫腺肌病和局灶型子宫肌腺病的患者,用MTX50mg子宫动脉局部灌注,并加用PVA微球颗粒(直径350～560μm)栓塞治疗。比较两组病例月经量、痛经程度、子宫体积及性激素水平等的术后变化及两组间是否存在差异。结果MTX局部灌注结合子宫动脉栓塞术,无化疗药物不良反应;经治疗的全部病例,月经量减少,痛经程度减轻。弥漫型子宫肌腺病子宫体积进行性缩小,与局灶型子宫腺肌病比较,疗效更为显著(P<0.05)。结论微创介入技术和药物相结合的方法可用于弥漫型子宫腺肌病和局灶型子宫腺肌病的治疗,尤其适宜于弥漫型子宫腺肌病。

Objective To study the efficacy of treating different types of uterine adenomyosis with transcatheter local infusion of methotrexate （MTX）combined with uterine arterial embolization under guidance of digital subtraction angiography （DSA）. Methods 33 cases were primarily screened out according to clinical symptoms and color Doppler and then further diagnosis as diffuse or local adenomyosis were undertaken with super selective uterine arterial angiography. The patients were then treated with uterine arterial local infusion （50 mg MTX）and embolization with PVA mierosphere（diameter 450 - 650 μm）, individually, Finally, the comparison between the preoperative and postoperative menstruation volumes, the degrees of dysmenorrheal, uterine sizes and the levels of sexual hormones of diffuse and local adenomyosis was carried out. Results The uterine arterial local infusion of MTX combined with embolization showed no chemotherapeutic side effects. In all cases, there were decrease of menstruation amount, alleviated dysmenorrhea, reduction of uterine size, and the efficacy was more evident in diffuse adenomyosis （P 〈 0.05）. Conclusions Micro-invasive interventional technique combined with drug therapy is promising for diffuse and local adenomyosis especially for the former.
