目的:探讨经阴道彩色多普勒超声(TVCDS)对子宫内膜癌肌层浸润程度诊断的价值,为合理选择治疗方案提供科学依据。方法:用TVCDS观察40例子宫内膜癌患者病灶的二维图像特征及血供特点,判断病灶与肌层的关系,并与术后病理结果相对照。结果:40例患者的子宫内膜平均厚度为20.3 mm,超声影像显示强弱不等回声,边缘不整,部分病例伴有不同程度的宫腔积液。有无肌层浸润的总准确率为85.7%。对无肌层浸润的准确率为83.3%,对浅肌层浸润的准确率为90%,对深肌层浸润的准确率为75%,其敏感性为85%,特异性为91.3%。结论:TVCDS能清晰显示病灶的大小、边缘、内部回声及其与肌层的关系及病灶的血供特点,对内膜癌肌层浸润程度的诊断准确率高,可作为术前判断内膜癌肌层浸润程度的首选检查方法。
Objective: To investigate the value of transvaginal color Doppler ultrasound (TVCDS) in the diagnosis of myometrial invasion in endometrial cancer and provide a scientific basis for rational choice of treatment. Methods: Two-dimensional image features and blood supply characteristics of 40 patients with endometrial carcinoma were observed by TVCDS to determine the relationship between the lesion and the myometrium, and compared with the postoperative pathological results. Results: The average thickness of endometrium in 40 patients was 20.3 mm. Ultrasound images showed unequal echoes and irregular edges. Some cases were accompanied with varying degrees of uterine effusion. The total accuracy of myometrial invasion was 85.7%. The accuracy of myometrial invasion was 83.3%, the accuracy of myometrial invasion was 90%, the accuracy of myometrial invasion was 75%, and the sensitivity and specificity were 85% and 91.3% respectively. Conclusion: TVCDS can clearly show the size of the lesion, the edge, the internal echo and its relationship with the muscular layer and the blood supply characteristics of the lesion. The accuracy of the diagnosis of endometrial carcinoma is high, which can be used as a preoperative diagnosis of endometrial cancer Myocardial infiltration degree of the preferred method of examination.
