Antidiastole Value of Three-dimensional Ultrasonography and Power Doppler between Uterine Parenchyma Lumps and Endometrial Cancer:A Retrospective Study

Sometimes endometrial polyps,submucosal myomas,and endometrial cancer show similar findings under ultrasonography.The aim of this study was to assess the antidiastole value of blood flow parameters using three-dimensional(3D)power Doppler ultrasonography angiography(PDA)between endometrial cancer and uterine parenchyma lumps.The data of the blood flow indices in 3D-PDA including the vascularization index(VI),flow index(FI),and vascularization flow index(VFI)in 40 patients with endometrial cancer and 41 patients with uterine parenchyma lumps(endometrial polyps and submucosal myomas)were retrospectively analysed and compared utilizing Virtual Organ Computer-aided AnaLysis(VOCAL)software.The results showed that all the blood flow parameters(VI,FI,VFI)were significantly higher in women with endometrial cancer than in those with uterine parenchyma lumps(P<0.001).The area under the curve of ROC of VI,FI,and VFI was 0.98,0.84,and 0.97,respectively.Thus,the best predictor of endometrial carcinoma was VI with a sensitivity of 97.0% and a specificity of 91.0%.The optimal cutoff value of VI was 4.06%.Our data demonstrated that all of the blood flow signal parameters(including VI,FI,and VFI)in 3D power Doppler ultrasonography had significant antidiastole values between endometrial cancer and uterine parenchyma lumps to assist clinicians in properly diagnosing patients.

The Prognostic Value of BMI, Serum Glucose, Endometrial Echo Pattern and Uterine Artery Doppler Velocimetry as a Predictor for Endometrial Pathology in Women with Postmenopausal Bleeding (Prospective Observational Study)

Background: Post-menopausal bleeding is a warning sign that accounts for about 5% of all outpatient gynaecologic visits and is a common indication for referral to rapid access clinics because of the fear of underlying malignancy. Endometrial malignancies differ from other malignancies in that early symptomization is common, allowing early cure. Patients and Methods: During the study period, 100 women with post-menopausal bleeding having inclusion criteria were evaluated in Al Hussein University Hospital. For each patient full history, general, abdominal and pelvic examination was performed. Routine pre-operative investigations were done. Patients were divided into four groups: Group 1 included 29 patients with endometrial polyp. Group 2 included 34 patients with endometrial hyperplasia. Group 3 included 21 patients with atrophic endometrium. Group 4 included 16 patients with endometrial carcinoma. Results: As regards the predictive value of BMI, in the study there was a high statistical significance in comparison between the endometrial carcinoma group and all other benign groups. When discussing the predictive value of blood glucose level, in the study there was a high statistical significance in comparison between the endometrial carcinoma group and all other benign groups. It is worth to mention that the predictive value of endometrial thickness, in the study, was with high statistical significance in comparison between the endometrial carcinoma group and all other benign groups providing the highest specificity and sensitivity. At the last the predictive value of uterine artery velocimetry, in the study, was with high statistical significance in comparison between the endometrial carcinoma group and all other benign groups. Conclusion: BMI, blood glucose level, endometrial thickness and uterine artery velocimetry indices, improve the prediction of endometrial carcinoma in women with post-menopausal bleeding.

Doppler Study of Uterine Artery and Ultrasonography of Endometrial Thickness in Perimenopausal and Postmenopausal Bleeding

Background: Transvaginal color Doppler sonography of the uterine artery has been reported useful for evaluation of abnormal uterine bleeding in peri-/post-menopausal women. It may differentiate physiological from malignant endometrial changes. Objective: Evaluating the endometrial thickness and uterine artery Doppler as an initial diagnostic tool to identify patients with abnormal endometrial pathology. Methods: This is a prospective case control study consisted of total 50 women with peri-(n = 35) and post-(n = 15) menopausal bleeding, with 20 women consisting control group (no bleeding) (peri-(n = 10) and post-menopausal (n = 10)). Double layer endometrial thickness and uterine-artery-Doppler waveforms were measured, with the latter being S/D ratio, RI and PI. These were related to histological findings (endometrial biopsy). Result: Patients with abnormal uterine bleeding (both peri- and postmenopausal) had a significantly higher mean endometrial thickness than the control women. Study group showed a significantly lower value of all Doppler indices (S/D ratio, RI and PI). In study group, patients with malignant endometrial pathology showed significantly thicker endometrium and significantly lower Doppler indices than those with benign pathology. Conclusion: The combination of endometrial thickness and uterine artery color Doppler pattern might predict uterine endometrial malignancy, although whether it can discriminate (screen) patients requiring endometrial biopsy is not evident. Further study is needed.

Study on the uterine artery and fetal umbilical artery hemodynamics in patients with HDP

Objective:To explore the uterine artery and fetal umbilical artery hemodynamic change in patients with HDP.Methods:A total of 80 patients with HDP who came to our hospital from July, 2015 to July, 2016 for pregnancy examination were included in the study and served as the observation group, while 80 healthy pregnant women who came for pregnancy examination in the same period were served as the control group. The pregnant women in the two groups were performed with sequential color Doppler ultrasound at gestation 30-40 weeks. The two-dimensional ultrasound apparatus was used to detect the uterine artery and umbilical artery. PI, RI, and S/D were recorded. The fetal BPD, head girth, femur length, and abdominal girth were measured. ELISA was used to detect 8-iso-PGF2α. The immunoturbidimetry was used to detect Cys-C and CRP.Results:The uterine artery PI, RI, and S/D in the observation group were significantly higher than those in the control group. The umbilical artery PI, RI, and S/D in the observation group were significantly higher than those in the control group. The fetal BPD, head girth, femur length, and abdominal girth in the observation group were significantly less than those in the control group. 8-iso-PGF2α, Cys C, and CRP levels in the observation group were significantly higher than those in the control group.Conclusions:The uterine artery and umbilical artery blood flow resistance in patients with HDP are significantly elevated, which can severely affect the placental blood perfusion and fetal growth and development, while the color Doppler ultrasound can provide a non-invasive diagnosis for fetal distress in uterus.

Transvaginal color Doppler monitoring of medicinal termination of early pregnancy: analysis of prolonged bleeding and choice of indications

Objectives:To observe trophoblastic and other blood flows after medicinal abortion, to analyze factors of prolonged bleeding, and to determine indications for medicinal termination of early pregnancy. Methods:Transvaginal color Doppler (TVCD) observation in combination with β--hCG determination in clinical trial involving 145 early pregnant women. Results: In cases of prolonged bleeding trophoblastic blood flow (TBF) is more significant. After aspiration of retained tissues, parallel to disappearance of TBF, prolonged uterine bleeding is stopped. Ectopics, lower--situated myoma and scar--site--implantation are relatively contraindicative for medicinal abortion. Too early pregnancy with too small embryonic--sac is not favourable. The sac is more difficult to be expelled. Prolonged bleeding can occur in cases of amenorrhea or recovery of menstruation due to retention of decidual tissues with microvilli. Conclusion: Retention of decidual tissues with microvilli plays an important role in the mechanism of prolonged uterine bleeding during medicinal termination of early pregnancy. TVCD is very helpful in monitoring this method. Ectopic pregnancy should be contraindicated. In cases of myoma or with history of cesarean section the location of implantation and myoma or scar should be examined by ultrasound before decision. Pregnancy of 6--7 weeks is more favorable for medicinal abortion.

Hemodynamic changes in arterial flow velocities throughout the first six months of pregnancy in buffalo heifers by Doppler ultrasonography

Objective: To assess blood flow parameters as well as Doppler indices at the first six months of pregnancy in buffalo heifers. Methods: A total of 15 healthy, cycling, buffalo heifers were examined twice per month. Examination of Doppler ultrasonography started from the first month till the sixth months of pregnancy. All animals were subjected to transrectal Doppler ultrasonography to assess ovarian and uterine blood flow. Resistance index, pulsatility index, peak systolic velocity, end diastolic velocity, and blood flow rate were measured of both ipsilateral and contralateral to the fetus side. Results: The resistance index was positively correlated with the pulsatility index (r=0.62, P<0.01) but negatively correlated with all other parameters. For both ovarian and uterine arteries ipsilateral and contralateral to the fetus, there was a reduction in the resistance index, with a significant increase (P<0.01) in peak systolic and end diastolic velocities in both ovarian and uterine arteries. The peak systolic and end diastolic velocities of the ipsilateral ovarian and uterine arteries increased linearly till the six months of pregnancy with increased growth demands of the fetus. The same for the uterine branch of the ovarian artery was done in the middle uterine artery and umbilical artery ipsilateral to the fetus side. Conclusions: This study provides reference data of the hemodynamic changes in both ovarian and uterine arteries that could be a valuable tool to evaluate all hemodynamic changes in the developing placenta/fetus. Transrectal Doppler ultrasonography proves to be a useful non-invasive method to assess utero-ovarian blood flow during pregnancy.

Colour Doppler Study of Umbilical Artery in Antenatal Women with Severe Preeclampsia and Foetal Outcome

Hypertensive disorders are the most common medical complications of pregnancy (7.15%). Doppler analysis of umbilical artery S/D ratio PI and RI, absent or reversal of EDV were evaluated and follow up results studied in severe preeclampsia women between 26 to 40 weeks. Doppler analysis of Uterine Artery and Middle Cerebral Artery is also studied. Doppler study guides in decision making and follows up in severe preeclampsia and guides in reducing perinatal morbidity and mortality. Period of Study: This is a prospective randomised study conducted at Niloufer Hospital for Women and Children Red Hills Hyderabad from September 2011 to June 2014. Material and Methods: 100 pregnant women with severe preeclampsia who attended Antenatal Out-Patient Department and got admitted in Emergency ward underwent Umbilical artery velocimetry by means of a Colour doppler vision (6000 Toshiba corp Tokyo Japan) using 3.5_5 MHZ Trasabdominal traducer. Results: Total number of 100 women were studied. In this 60 women had foetuses with abnormal umbilical artery flow velocimetry and 40 had normal umbilical artery flow velocimetry. The average birth weight and diagnosis to delivery interval were lower in foetuses with abnormal umbilical artery doppler. Admission to neonatal intensive care unit is high. The APGAR score at 1 minute is <7 in 20 women with abnormal umbilical artery doppler compared to 17 women with normal umbilical artery doppler. Compared to 32 women with normal umbilical artery doppler, the APGAR score is more than 7 in 31 women with abnormal umbilical artery Doppler. P = 0.639647 and chi-square statistic = 0.2192, the result is statistically not significant at p-value < 0.05, implying that APGAR scores are not dependent on doppler findings alone. Conclusion: Doppler study guides obstetrician to assess the physiological status of the foetus and it helps in identifying the changes in the foetal circulation. This study suggests that doppler assessment of foe to placental circulation including umbilical artery is a better prognostic indicator in severe PE and helps in timely intervention. The foetuses with normal artery flow velocimetry area at a lower risk of having poor APGAR score than those with abnormal velocimetry and NICU admissions are less with normal umbilical artery flow velocimetry. The average birth weight of neonates with abnormal umbilical artery was lower compared to neonates with normal umbilical artery velocimetry.

Female Contraception: Comparative Study of Biometrics and Vascularization of the Uterus at Sylvanus Olympio University Hospital (Togo)

Female contraception uses both hormonal and non-hormonal methods. The aim of the study is to determine the impact of female contraception on uterine vascularisation and the endometrium. Method: It was a descriptive comparative study with an analytical aim. It took place at the University Clinic of Obstetrics Gynaecology and the Radiology and Medical imaging Department of Sylvanus Olympio University Hospital in Lomé over a two-month period from May 15, 2023 to July 15, 2023. Group 1 included women using a modern contraceptive method and group 2 women not using a modern contraceptive method. Epidata 3.1 and R 4.0.4 software were used to process the data. Results: Each group included 50 women. There were no significant differences in uterine and endometrial biometrics. All women on contraception had their zone 1 vascularized, without vascularisation of zone 2, without significant difference with women without contraception The pulsatility index was greater than 3 in 51% (n = 51) of women, including 62.7% (n = 32) of women without contraception and 37.3% (n = 19) of women on contraception, with a statistically significant difference (p = 0.009). Conclusion: Contraceptive methods do not influence the biometry of the uterus. However, uterine artery Doppler indices can predict abnormal uterine bleeding.

目的:探讨阴道彩色多普勒超声血流显像(CDFI)对子宫肌瘤的诊断效能及其图像特征.方法:选取 2020年1 月至 2022 年 12 月本院收治的 53 例子宫肌瘤患者为研究对象,纳入观察组.选取同期本院收治的 51 例子宫肉瘤患者作为对照,纳入对照组.比较两组经阴道CDFI检查的图像特征、瘤体内部血流信号,CDFI检查对两组患者的诊断效能.结果:观察组CDFI图像呈低回声、瘤体边界清楚、肌瘤内部实性患者,瘤体内部无血流信号、少量血流信号患者占比均大于对照组;瘤体边界欠清楚、肌瘤内部囊性患者、瘤体内部血流信号丰富患者占比,均小于对照组,差异均有统计学意义(P<0.05).阴道CDFI检查诊断子宫肌瘤和子宫肉瘤的特异度、灵敏度、准确率、阳性预测值、阴性预测值分别为 98.03%、96.22%、97.11%、98.07%、96.15%.结论:采取阴道CDFI检查对子宫肌瘤诊断具有较高诊断效能,可清楚显示子宫肌瘤患者图像特征.

经阴道与腹部彩超在鉴别诊断子宫肌瘤及子宫腺肌瘤中的临床意义

目的探讨经阴道与腹部彩超在鉴别诊断子宫肌瘤、子宫腺肌瘤中的临床意义。方法选取2017年1月至2020年1月萍乡市第二人民医院收治的40例子宫腺肌瘤患者作为子宫腺肌瘤组,另选取同期本院收治的40例子宫肌瘤患者作为子宫肌瘤组,两组均经手术病理学确诊。术前,两组均行经阴道与腹部彩超检查。比较两组经阴道与腹部彩超的检出率、血流指标(阻力指数、搏动指数),比较两种检查方法检查依从性。结果两组经阴道彩超检出率均高于经腹部彩超,差异有统计学意义(P<0.05)。两组经阴道与腹部彩超搏动指数比较差异无统计学意义;两组经阴道彩超阻力指数大于经腹部彩超,差异有统计学意义(P<0.05);子宫腺肌瘤组经腹部彩超、经阴道阻力指数、超声搏动指数均大于子宫肌瘤组,差异有统计学意义(P<0.05)。经阴道与腹部彩超检查依从性比较差异无统计学意义。结论经阴道与腹部彩超在鉴别诊断子宫肌瘤、子宫腺肌瘤效果显著,其中经阴道彩超检出率更高,且对于子宫肌瘤、子宫腺肌瘤血流动力学的检测更明显,值得临床推广应用。

彩色多普勒超声对子宫腺肌症和子宫肌瘤的鉴别诊断价值及检出率探究

目的探讨彩色多普勒超声在子宫腺肌症与子宫肌瘤临床诊断中的应用价值。方法选取2019年1月至2021年12月吉安市中心人民医院收治的70例子宫腺肌症与子宫肌瘤患者作为研究对象,根据疾病种类分为子宫腺肌症组(n=32)与子宫肌瘤组(n=38)。两组均接受彩色多普勒超声诊断检查。比较两组肿瘤内血液丰富程度分级、子宫腺肌症与子宫肌瘤的检出率、血流量(BFV)、子宫动脉阻力指数(RI)与搏动指数(PI)。结果子宫腺肌症患者的超声图像特征为子宫轻度弥漫性增大为主,彩色多普勒血流显像为病灶区域血流较少,可见短条状的稀疏血流;子宫肌瘤患者的超声图像特征为子宫增大,彩色多普勒血流显像为包块内存在条状或星状的血流信号。两组肿瘤内血液丰富程度分级比较差异无统计学意义;以临床病理检查结果为金标准,两组子宫腺肌症与子宫肌瘤检出率比较差异无统计学意义;子宫腺肌症组BFV慢于子宫肌瘤组,PI低于子宫肌瘤组,RI高于子宫肌瘤组,差异有统计学意义(P<0.05)。结论彩色多普勒超声检查在临床诊断中有利于鉴别子宫腺肌症患者与子宫肌瘤患者,对患者的确诊与治疗具有重要的指导意义。
