经阴道彩色多普勒超声鉴别卵巢肿瘤的临床价值

Clinical Value of Transvaginal Color Doppler Ultrasound in Differential Diagnosis of Benign and Malignant Ovarian Tumor

目的:探讨经阴道彩色多普勒超声检查在鉴别卵巢良性和恶性肿瘤方面的价值。方法:选取在我院就诊的卵巢肿瘤患者81例作为研究对象,所有对象术前均行经阴道彩色多普勒超声检查,以观察患者瘤内血流分级情况及肿瘤内动脉血流参数。结果:卵巢良性肿瘤组患者瘤内血流分级以0级和Ⅰ级为主,占90.00%,而卵巢恶性肿瘤组患者瘤内血流分级以Ⅲ级为主,占68.52%,与卵巢良性肿瘤组患者相比,卵巢恶性肿瘤组患者的血流分级明显升高;交界性肿瘤患者的瘤内血流分级以Ⅱ级和Ⅲ级为主,与卵巢良性肿瘤组患者比较有明显差异(P<0.05),与卵巢恶性肿瘤组患者相比无明显差异(P>0.05)。与卵巢良性肿瘤组患者相比,卵巢恶性肿瘤组患者的动脉血流阻力指数和搏动指数明显降低(P<0.05)。结论:血管分级、动脉血流阻力指数及波动指数有助于鉴别卵巢良性和恶性肿瘤。

Objective：To study the clinical value of transvaginal color Doppler ultrasound in differential diagnosis of benign and malignant ovarian tumor.Methods：A total of 81 patients with ovarian tumor were enrolled into this study in our hospital.Before operation,all the subjects were received the transvaginal color Doppler ultrasound in order to detect parameters including the arterial vascular parameters and the vascular grading.Results：90.00% benign ovarian tumors were categorized as grade 0and gradeⅠ,while 68.52% malignant ovarian tumors were difined as hyper-vascularity（gradeⅢ）.Significant differences were found in the vascular grading between the two groups.Most borderline tumors were categorized as gradeⅡ or gradeⅢ,which were similiar to malignant tumor（P〉0.05）but significantly different from the benign tumor（P〈0.05）.Compared with those of the benign tumor,the artery resistance index and pulsation index of the malignant tumor was significant lower（P〈0.05）.Conclusion：In clinical decisions,the artery resistance index,pulsation index,and the vascular grading are useful indicators for the differential diagnosis of ovarian tumors.
