Heterotopic pregnancies are rare and difficult to be diagnosed early. A patient with combined intrauterine pregnancy and cervical pregnancy was admitted in Qingdao Municipal Hospital in 2019. The patient complained of abnormal vaginal bleeding after menopause and was misdiagnosed as simple intrauterine pregnancy. She underwent artificial abortion and suffered intraoperative hemorrhage. To stop bleeding, she received the treatment of uterine artery embolization immediately. Afterwards, cervical residual pregnancy tissues started necrosis, blood β-human chorionic gonadotropin level and the cervix appearance gradually returned to normal. This report suggests that cervical heterotopic pregnancy inclines to be mis diagnosed. Correct diagnosis should be made as soon as possible. Selective uterine artery embolization is an effective measure to prevent and treat massive bleeding.

uterine artery Doppler indices, and fetal presentation.RESULTS: We established a specific protocol for the measurement of cervical elastography using the E cervix program. For all elastographic parameters, the intra-observer intraclass correlation coefficient (ICC) ranged from 0.633 to 0.723 for single measures and from 0.838 to 0.887 for average measures, and the inter-observer ICC ranged from 0.814 to 0.977 for single measures and from 0.901 to 0.988 for average measures. Regression analysis showed that the measurement of the elastographic parameter was not affected by baseline clinical factors.CONCLUSION: We present a standardized protocol for the measurement of cervical elastography using intrinsic compression. According to this protocol, reproducibility was acceptable and the measurement of elastographic parameters was not affected by the baseline clinical factors studied.]]>

Arteriovenous malformations (AVM) are vascular disorders with a mixture of arterial, venous and small capillary-like channels with fistulous connections. Uterine arteriovenous malformations are rare cause of abnormal uterine bleeding with only a few reported cases. They may arise from pregnancy, miscarriage, previous cesarean section or other uterine surgery and gestational trophoblastic disease. Diagnosis can be made through angiography or doppler ultrasonography. Traditionally, uterine AVMs are treated with hysterectomy but with the advances in technology, minimally invasive conservative approaches such as radiologic arterial embolization or laparoscopic uterine artery ligation have become available. We present a case of a 29-year-old, G2P1 (1011) who had a three- month history of heavy, intermittent vaginal bleeding from uterine arteriovenous malformation after a miscarriage. Laparoscopic bilateral uterine artery occlusion, offered a minimally invasive treatment with high symptomatic effectiveness.

Uterine arteriovenous vascular malformation (UAVM) is a disease that causes excessive bleeding. The symptoms do not subside without proper treatment and this can lead to life-threatening situations. The correct diagnosis of UAVM can be complicated if the patient's uterus did not completely discharge everything during abortion (in broader terms, retaining remnants of the products of conception). In this case, Doppler ultrasonography and computed tomography angiography with 3-dimensional rendering were used to analyze the cause of bleeding and provide proper treatment of this patient. Then, uterine artery embolization, dilatation, and curettage were performed safely and successfully. The patient no longer had symptoms of vaginal spotting during the planned follow up care. UAVM is uncommon; however, if reproductive-age women show repeated abnormal vaginal bleeding after dilatation and curettage, a diagnosis of UAVM must be considered based on the medical history and examination.

OBJECTIVE: To evaluate the outcome of re-pregnancy in women with uterine artery embolization(UAE)for postpartum hemorrhage(PPH). METHODS: Clinical data of 117 pregnant women with previous PPH admitted in Ningbo Women and Children's Hospital from January 2010 to January 2016 were retrospectively analyzed. Among them 40 cases were treated with UAE (UAE group) and 77 cases were not treated with UAE (control group). The outcomes of re-pregnancy were followed up and compared between two groups. RESULTS: There were significant differences in the incidence of induced abortion in early pregnancy and cesarean scars pregnancy (CSP) between the two groups (<0.05 or <0.01). In the UAE group, the incidence of PPH, placental accretion and hysterectomy rate was significantly higher than that of control group (<0.05 or <0.01). Multivariate analysis showed that UAE was independent risk factor for CSP, placenta accretion, PPH and hystere-ctomy (<0.05 or <0.01). CONCLUSIONS The overall fertility and re-pregnant outcomes in women with previous UAE for PPH are favorable. However, the risk of CSP, placenta accretion and associated recurrence of PPH and hysterectomy is higher in women receiving UAE during subsequent pregnancy.

Objective To study the anatomical variations of the origin of uterine artery(UA)by three-dimensional(3D)reconstructed computed tomography angiography(CTA)and facilitate the preoperative evaluation for gynecological surgeries or interventional therapies. Method The CTA findings of 112 patients with an average age of(31.4±6.6)years old who had received a pelvic CTA and undergone 3D reconstruction of the uterine artery were retrospectively analyzed. Results The average uterine volume was(95.6±26.8)cm .Of the UA 224 sides,144 sides(64.3%)arose from the interior gluteal artery and 51(22.8%)from internal iliac artery;in 29 sides(12.9%),the uterine artery,the inferior gluteal and the superior gluteal arteries arising as a trifurcation.The origin of UA was consistent between left and right sides in 68 patients(60.7%)and not in 44 patients(39.3%). Conclusion As a rapid,noninvasive,and economic technique,CTA can effectively display the anatomical variations of the origin of UA and thus can be used to guide interventional therapies and gynaecological surgeries.

Since its introduction in 1995, uterine artery embolization (UAE) has become an established option for the treatment of leiomyomas. Identification of a leiomyoma using arteriography improves the ability to perform effective UAE. UAE is not contraindicated in a pedunculated subserosal leiomyoma. UAE in a cervical leiomyoma remains a challenging procedure. A leiomyoma with high signal intensity on T2-weighted imaging responds well to UAE, but a malignancy with similar radiological features should not be misdiagnosed as a leiomyoma. Administration of gonadotropin-releasing hormone agonists before UAE is useful in selected patients and is not a contraindication for the procedure. The risk of subsequent re-intervention 5 years after UAE is approximately 10%, which represents an acceptable profile. UAE for adenomyosis is challenging; initial embolization using small particles can achieve better success than that by using larger particles. An intravenous injection of dexamethasone prior to UAE, followed by a patient-controlled analgesia pump and intra-arterial administration of lidocaine after the procedure, are useful techniques to control pain. Dexmedetomidine is an excellent supplemental sedative, showing a fentanyl-sparing effect without causing respiratory depression. UAE for symptomatic leiomyoma is safe and can be an alternative to surgery in most patients with a low risk of re-intervention.

OBJECTIVE: To evaluate the performance of the preeclampsia (PE) screening algorithm of the Fetal Medicine Foundation (FMF) during the first trimester in a Brazilian population using maternal characteristics, mean arterial pressure (MAP), and uterine artery Doppler data. METHODS: This is a prospective cohort study that evaluated 701 pregnant women during the first trimester ultrasound screening for chromosomal abnormalities (11–13+6 weeks). All patients provided information regarding clinical and obstetric history, MAP, and mean uterine artery pulsatility index (mean PI). Patients were assigned to four groups based on the presence of PE and gestational age at delivery: group 1 (control), patients without hypertensive disorders (n=571); group 2, PE and delivery before 34 weeks of gestation (n=7); group 3, PE and delivery before 37 weeks of gestation, including patients from group 2 and patients that presented PE with delivery between 34 and 37 weeks (n=17); and group 4, PE and delivery before 42 weeks of gestation, including patients from both groups 2 and 3 and patients that presented PE with delivery between 37 and 42 weeks of gestation (n=34). RESULTS: After the exclusion of 96 patients, we evaluated the data of 605 patients. By combining maternal characteristics, MAP, and the mean uterine artery PI for the detection of PE, we found a sensitivity of 71.4% in group 2, 50% in group 3, and 41.2% in group 4 (false positive rate=10%). CONCLUSION: Using maternal characteristics, MAP, and uterine artery Doppler data, we were able to identify a significant proportion of patients who developed preterm PE.

OBJECTIVE: Bilateral uterine artery ligation (UAL) is a fertility-preserving procedure used in women experiencing postpartum hemorrhage (PPH). However, the long-term effects of this procedure on ovarian function remain unclear. The aim of this study was to investigate whether bilateral UAL compromised ovarian reserve and ovarian blood supply. METHODS: This prospective study included 49 women aged between 21 and 36 years who had undergone a cesarean section for obstetric indications. Of these, 25 underwent uterine bilateral UAL to control intractable atonic PPH. The control group consisted of 24 women who had not undergone bilateral UAL. Standard clinical parameters, the results of color Doppler screening, and ovarian reserve markers were assessed in all participants at 6 months after surgery. The clinical parameters included age, parity, cycle history, body mass index, and previous medication and/or surgery. Color Doppler screening findings included the pulsatility index (PI) and resistance index (RI) for both the uterine and ovarian arteries. The ovarian reserve markers included day 3 follicle-stimulating hormone (FSH) levels, antral follicle count, and anti-Müllerian hormone (AMH) levels. RESULTS: There were no significant differences in the ovarian reserve markers of day 3 FSH levels, antral follicle count, and AMH levels between the study and control groups (p>0.05 for all). In addition, no significant differences were observed in the PI and RI indices of the uterine and ovarian arteries (p>0.05 for all). CONCLUSION: In this study, we showed that bilateral UAL had no negative effects on ovarian reserve or ovarian blood supply, so this treatment should be used as a fertility preservation technique to avoid hysterectomy in patients experiencing PPH.

OBJECTIVE: To sonographically evaluate the dominant fibroid nodule vascularity and flow velocity pattern of perifibroid and intrafibroid arteries. METHODS: We recruited 140 women with uterine fibroids. Their uteri were scanned to determine the vascularity of fibroid nodules and the Doppler indices of the fibroid arteries. RESULTS: The median volume of the dominant leiomyoma nodule was 133 cm3 (range=1.5–2,575 cm3). Eighty-three subjects (59.3%) had a dominant leiomyoma nodule volume of ≤200.0 cm3 while the volume of the dominant leiomyoma nodule was >200.0 cm3 in 57 (40.7%) subjects. The dominant fibroid nodule was vascular in 137 (97.9%) subjects and avascular in 3 (2.1%). All the perifibroid artery indices (except the end-diastolic velocity [EDV] and diastolic average ratio [DAR]) are significantly higher than those of the intrafibroid artery. The mean Doppler indices of perifibroid vs. intrafibroid arteries as follows: peak systolic velocity (PSV; 52.1 vs. 45.4 cm/s); EDV (21.1 vs. 22.4 cm/s); time-averaged maximum velocity (TAMX; 31.5 vs. 30.4 cm/s); time- averaged mean velocity (Tmean; 14.3 vs. 13.8 cm/s); pulsatility index (PI; 1.1 vs. 0.8); resistive index (RI; 0.6 vs. 0.5); systolic-diastolic ratio (SDR; 2.7 vs. 2.1); impedance index (ImI; 2.7 vs. 2.1); and DAR (0.66 vs. 0.74); P < 0.001 for all indices. CONCLUSION: The predominant pattern of fibroid vascularity is peripheral vascularity and the perifibroid artery indices (except EDV and DAR) are significantly higher than those of the intrafibroid artery. Recurrent fibroids in women with previous myomectomy had significantly higher intrafibroid PI, RI, SDR, and ImI than those without previous myomectomy.
