Pelvic sonoangiography (PSAG) using transvaginal color Doppler was done on 16 postmenopausal patients with abnormal uterine bleeding. Seven women had no endometrial carcinoma and nine had carcinoma. No flow was detected around and within the endometrium in noncancer patients. PSAG showed a feeder artery (blood flow with pulsation that runs into and clings to the tumor) in all patients with endometrial carcinoma, and intratumor blood flow (a mixture of pulsating and constant flow within the tumor) was evident in 7 of 9 patients with endometrial carcinoma. These findings were confirmed by conventional pelvic angiography. In the diagnostic evaluation of PSAG for endometrial carcinoma, both sensitivity and specificity were 100%. We conclude that PSAG with transvaginal color Doppler can be used to detect endometrial carcinoma in postmenopausal women with abnormal uterine bleeding and that this method might be applicable to selecting patients who really require diagnostic surgery for endometrial cancer.
对16例绝经后子宫异常出血患者进行了经阴道彩色多普勒盆腔血管造影（PSAG）检查。7名女性无子宫内膜癌，9名患有癌症。非癌症患者的子宫内膜周围和内部未检测到血流。PSAG显示所有子宫内膜癌患者均有一条供血动脉（有搏动的血流进入并附着于肿瘤），9例子宫内膜癌患者中有7例肿瘤内部血流明显（肿瘤内部搏动性血流和持续性血流混合）。这些发现通过传统盆腔血管造影得到证实。在PSAG对子宫内膜癌的诊断评估中，敏感性和特异性均为100%。我们得出结论，经阴道彩色多普勒PSAG可用于检测绝经后子宫异常出血女性的子宫内膜癌，并且该方法可能适用于选择真正需要进行子宫内膜癌诊断性手术的患者。
