INTRODUCTION: Traditional diagnostic workup for Endometrial carcinoma in women with post-menopausal bleeding (PMB) involves endometrial biopsy. Addition of colour and power Doppler ultrasound to transvaginal ultrasonography (TVS) might help in differentiating subset of women who are at high risk of carcinoma. The aim of this study was to determine the diagnostic value of Pulsatility Index (PI) and Resistance Index (RI) of uterine and spiral artery in PMB and to determine the diagnostic value of power Doppler flow mapping in them.
MATERIAL AND METHODS: A prospective study was done amongst 50 women with PMB. All women were subjected to TVS including uterine artery and spiral artery Doppler velocimetry, power Doppler flow mapping of spiral artery, hysteroscopy and endometrial biopsy.
RESULTS: Uterine artery PI and RI values were overlapping between benign and malignant endometrial pathologies. Whereas spiral artery PI ≤ 0.33 and RI ≤ 0.5 helps in differentiating malignant frombenign pathology. Power Doppler multiple vessel pattern is also found to have a better diagnostic ability in picking endometrial cancer.
CONCLUSION: Addition of spiral artery velocimetry and power Doppler flow mapping to those with thickened endometrium, aids in differentiating endometrial malignancy from benign pathology. This might be helpful in counselling the women for endometrial biopsy, as histopathological analysis is the gold standard diagnostic modality.
