Abstract: ［Abstract］ Objective〖HTSS〗〓To investigate the relationship between microvessels and cervical cancer metastasis detected by color Doppler ultrasound.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Sixty  patients with cervical cancer were selected in this study. All patients were diagnosed by color Doppler ultrasound imaging and then treated with surgery. The number of lymph nodes removed after operation was recorded and the pathological examination was performed. The type of cervical cancer, vascular involvement, parametrial infiltration and interstitial infiltration depth were detected and recorded. The relationship between the blood flow richness of cervical cancer lesion and the type of cervical cancer, vascular involvement, parauterine infiltration and interstitial infiltration depth was analyzed. The logistic multiple regression analysis was used to analyze the risk factors of cervical cancer metastasis.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓A total of 29 cases(48.3%) of pelvic lymphatic metastasis were found by operation and postoperative pathological examination. A total of 25 cases(41.7%) of pelvic metastasis were found by color Doppler ultrasonography. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of color Doppler ultrasound were 82.76%, 96.77%, 90.00%, 96.00% and 85.74%, respectively. Compared with those without parametrial infiltration, no vascular involvement, interstitial infiltration depth(<10 mm) and no lymph node metastasis, the blood flow was abundant in patients with parametrial infiltration, vascular involvement, interstitial infiltration depth(≥10 cm) and lymph node metastasis. The logistic regression analysis showed that parametrial infiltration, vascular involvement, interstitial infiltration and lymphatic metastasis were the high risk factors for cervical cancer with abundant blood flow.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The color Doppler ultrasound imaging system has a good consistency with pathological results in lymphatic metastasis of cervical cancer patients, and lymphatic metastasis combined with the detection of blood flow richness has a good diagnostic value for cervical cancer metastasis.
