【摘要】:研究背景: 子宮肌瘤是育齡女性最常見的良性腫瘤,發(fā)病率為20-40%,其中50%的患者有臨床癥狀而需要治療,高強(qiáng)度聚焦超聲(HIFU)能安全有效用于消融子宮肌瘤,并且作為一種非侵入治療手段,得到了越來越多的認(rèn)可。但如何進(jìn)一步提高HIFU消融效果,縮短治療時(shí)間,一直是臨床研究的重點(diǎn)。超聲造影劑(聲諾維),主要成分為六氟化硫微泡,超聲微泡可改變聲環(huán)境。回顧性研究顯示使用超聲造影劑(聲諾維)在超聲消融治療子宮肌瘤時(shí)可能起到增效作用,但目前尚未見超聲造影劑(聲諾維)提高HIFU消融子宮肌瘤效率的前瞻性研究的報(bào)道。 目的: 探討超聲造影劑(聲諾維)在高強(qiáng)度聚焦超聲消融治子宮瘤時(shí)的增效作用及安全性評(píng)價(jià)。 資料和方法: 使用由重慶海扶技術(shù)有限公司研制的高強(qiáng)度聚焦超聲腫瘤治療系統(tǒng)(JC200),在遂寧市中心醫(yī)院選擇確診的80例單發(fā)子宮肌瘤患者,隨機(jī)分為造影劑組(40例)和非造影劑組(40例)。造影劑組在HIFU手術(shù)前后均靜脈推注1.5ml超聲造影劑(聲諾維),非造影劑組僅在HIFU術(shù)后靜脈推注1.5ml超聲造影劑(聲諾維),比較造影劑組和非造影劑組的團(tuán)塊狀灰度變化出現(xiàn)率、EEF、消融率以及HIFU術(shù)中、HIFU術(shù)后即刻不良反應(yīng)發(fā)生率等。 結(jié)果: (1)造影劑的40例患者中有33個(gè)(82.5%)肌瘤治療時(shí)出現(xiàn)團(tuán)塊狀灰度變化, EEF(消融單位體積病灶組織所需的超聲能量)為9.1±9.9(范圍:0.4-56.8)J/mm3,消融率為90.4±8.3(范圍:66.4-100)%;在未使用造影劑的40例患者中,有20個(gè)(50.0%)肌瘤治療時(shí)出現(xiàn)團(tuán)塊狀灰度變化,EEF為12.9±15.7(范圍:1.5-71.1)J/mm3,消融率為82.8±13.3(范圍:53.4-100)%,其P值分別為0.002、0.029、0.006,均0.05,有統(tǒng)計(jì)學(xué)差異。 (2)HIFU術(shù)中造影劑組:放射痛12.5%、骶尾部痛60%、皮膚燙57.5%、治療區(qū)痛57.5%、腹股溝痛5.0%、無臀部皺褶痛、肛門墜脹2.5%、恥骨聯(lián)合痛2.5%、臀部痛2.5%,非造影劑組:放射痛87.5%、骶尾部痛72.5%、皮膚燙77.5%、治療區(qū)痛67.5%、腹股溝痛17.5%、臀部皺褶痛10%、肛門墜脹2.5%、無恥骨聯(lián)合痛、無臀部痛,其P值分別為:0、0.469、0.056、0.356、0.077、0.051、1、0.314、0.314,均0.05,無明顯差異。 (3)HIFU術(shù)后即刻造影劑組:無發(fā)熱、下腹痛47.5%、骶尾部痛。25.0%、無下肢感覺異常、陰道排液5.0%、皮膚損傷2.5%、無肛門墜脹,非造影劑組:無發(fā)熱、下腹痛42.5%、骶尾部痛30.0%、無下肢感覺異常、陰道排液7.5%、無皮膚損傷、肛門墜脹2.5%,其P值分別為:1、0.653、0.617、1、0.644、0.314、0.314,均0.05,,無明顯差異。 結(jié)論: 超聲造影劑(聲諾維)能提高HIFU消融子宮肌瘤的作用,減少HIFU治療的能量,無明顯不良反應(yīng),具有很好的臨床應(yīng)用價(jià)值,值得進(jìn)一步推廣研究。
[Abstract]:Research background:
Uterine leiomyoma is the most common benign tumor of women of childbearing age, the incidence rate was 20-40%, of which 50% of the patients had clinical symptoms and the need for treatment of high intensity focused ultrasound (HIFU) is safe and effective for ablation of uterine fibroids, and as a non-invasive treatment, has been more and more recognized. But how to further improve the HIFU the ablation effect, shorten treatment time, has been the focus of clinical research. Ultrasound contrast agent (SonoVue), is mainly composed of six sulfur hexafluoride microbubbles, ultrasound microbubbles can change the acoustic environment. A retrospective study showed that the use of ultrasound contrast agent (SonoVue) in ultrasound ablation in treatment of uterine fibroids may play a synergistic effect. But there is no ultrasound contrast agent (SonoVue) to improve the prospective study of HIFU ablation for uterine fibroids efficiency reports.
Objective:
Study of ultrasound contrast agent (SonoVue) ablation synergistic effect and safety evaluation of the treatment of uterine tumor with high intensity focused ultrasound.
Information and methods:
The use of high intensity focused ultrasound tumor therapy system developed by Chongqing Haifu Technology Co. Ltd. (JC200), were chosen in Suining Central Hospital 80 cases of patients with single uterine fibroids were randomly divided into the contrast group (40 cases) and contrast group (40 cases). Contrast group in the HIFU vein before and after operation infusion of 1.5ml ultrasound contrast agent (SonoVue), non contrast group only at HIFU after intravenous injection of 1.5ml ultrasound contrast agent (SonoVue), contrast agent group and the mass of gray change non contrast agent group occurrence rate, EEF, HIFU and ablation rate during operation, postoperative adverse reactions immediately HIFU occurrence rate.
