Contribution of spiral artery blood flow changes assessed by transvaginal color Doppler sonography for predicting endometrial pathologies

Abstract

Objective: To investigate the diagnostic value of blood flow measurements in spiral artery by transvaginal color Doppler sonography (CDS) in predicting endometrial pathologies. Methods: Ninety-seven patients presenting with abnormal uterine bleeding and requiring endometrial assessment were included in this prospective observational study. Endometrial thickness, structure and echogenicity were recorded. Pulsatility index (PI) and resistive index (RI) of the spiral artery were measured by transvaginal CDS. Endometrial sampling was performed for all subjects. Sonographic and hystopathologic findings were compared. Results: The histopathological diagnoses were as follows; 39 cases (40.2%) endometrial polyp, 9 cases (9.3%) endometrial hyperplasia, 10 cases (10.3) submucous myoma, 7 cases (7.2%) endometrium cancer, and 32 cases (33%) nonspecific findings. The spiral artery PI in endometrium cancer group was highly significantly lower than other groups (p

Endometrial patolojileri öngörmede transvajinal renkli Doppler ultrasonografi ile belirlenen spiral arter akım değişikliklerinin katkısı

Abstract

Amaç: Endometrial patolojilerin değerlendirilmesinde transvajinal renkli Doppler ultrasonografi (RDU) ile spiral arter akım parametrelerinin katkısını araştırmak. Yöntemler: Anormal uterin kanama ile başvurmuş ve endometrial değerlendirme ihtiyacı olan 97 hastanın katıldığı prospektif gözlemsel bir çalışmadır. Endometrial kalınlık, yapı ve ekojenite kaydedildi. Transvajinal RDU ile spiral arter pulsatilite indeksi (Pİ) ve rezistif indeksi (Rİ) ölçüldü. Tüm olgulara endometrial örnekleme yapıldı. Ultrasonografik ve histopatolojik bulgular karşılaştırıldı. Bulgular: Histopatolojik tanılar; 39 olgu (%40,2) endometrial polip, 9 olgu (%9,3) endometrial hiperplazi, 10 olgu (%10,3) submuköz myom, 7 olgu (%7,2) endometrium kanseri, 32 olgu (%33) nonspesifik bulgular. Endometrial kanser olgularında spiral arter Pİ istatistiksel olarak yüksek anlamlılıkta düşük bulundu (p
