RESUMO

Cerebral cavernous malformation is a rare but important cause of cerebral hemorrhage in pregnancy and puerperium. In pregnancy, cavernomas can more easily bleed as a result of increased female hormones and growth factors such as vascular endothelial growth factor. We present the case of a pregnant woman who had been diagnosed with a cerebral cavernoma about ten years previously, after repeated headache episodes; at the 28th week of pregnancy the woman was hospitalized for epileptic seizures and active bleeding from the anterior cerebral artery. We describe the management of the case, the decision for a preterm delivery and for a resolutive neurosurgical procedure.

RESUMO

Fetal alcohol spectrum disorder (FASD) is a set of conditions resulting from prenatal alcohol exposure (PAE). FASD is estimated to affect between 2% and 5% of people in the United States and Western Europe. The exact teratogenic mechanism of alcohol on fetal development is still unclear. Ethanol (EtOH) contributes to the malfunctioning of the neurological system in children exposed in utero by decreasing glutathione peroxidase action, with an increase in the production of reactive oxygen species (ROS), which causes oxidative stress. We report a case of a mother with declared alcohol abuse and cigarette smoking during pregnancy. By analyzing the ethyl glucuronide (EtG, a metabolite of alcohol) and the nicotine/cotinine in the mother's hair and meconium, we confirmed the alcohol and smoking abuse magnitude. We also found that the mother during pregnancy was a cocaine abuser. As a result, her newborn was diagnosed with fetal alcohol syndrome (FAS). At the time of the delivery, the mother, but not the newborn, had an elevation in oxidative stress. However, the infant, a few days later, displayed marked potentiation in oxidative stress. The clinical complexity of the events involving the infant was presented and discussed, underlining also the importance that for cases of FASD, it is crucial to have more intensive hospital monitoring and controls during the initial days.

RESUMO

(1) Background: Genitourinary syndrome of menopause (GSM) is a medical condition that can affect breast cancer survivors (BCS). This is a complication that often can occur as a result of breast cancer treatment, causing symptoms such as vaginal dryness, itching, burning, dyspareunia, dysuria, pain, discomfort, and impairment of sexual function. BCS who experience these symptoms negatively impact multiple aspects of their quality of life to the point that some of them fail to complete adjuvant hormonal treatment; (2) Methods: In this systematic review of the literature, we have analyzed possible pharmacological and non-pharmacological treatments for GSM in BCS. We reviewed systemic hormone therapy, local hormone treatment with estrogens and androgens, the use of vaginal moisturizers and lubricants, ospemifene, and physical therapies such as radiofrequency, electroporation, and vaginal laser; (3) Results: The data available to date demonstrate that the aforementioned treatments are effective for the therapy of GSM and, in particular, vulvovaginal atrophy in BCS. Where possible, combination therapy often appears more useful than using a single line of treatment; (4) Conclusions: We analyzed the efficacy and safety data of each of these options for the treatment of GSM in BCS, emphasizing how often larger clinical trials with longer follow-ups are needed.

RESUMO

BACKGROUND: Endometriosis is a chronic, estrogen-dependent, inflammatory disease, whose pivotal symptoms are dysmenorrhea, dyspareunia, and chronic pelvic pain (CPP). Besides the usual medical treatments, recent evidence suggests there are potential benefits of oral N-acetylcysteine (NAC) on endometriotic lesions and pain. The primary objective of this prospective single-cohort study was to confirm the effectiveness of NAC in reducing endometriosis-related pain and the size of ovarian endometriomas. The secondary objective was to assess if NAC may play a role in improving fertility and reducing the Ca125 serum levels. METHODS: Patients aged between 18-45 years old with a clinical/histological diagnosis of endometriosis and no current hormonal treatment or pregnancy were included in the study. All patients received quarterly oral NAC 600 mg, 3 tablets/day for 3 consecutive days of the week for 3 months. At baseline and after 3 months, dysmenorrhea, dyspareunia and CPP were assessed using the Visual Analog Scale score (VAS), while the size of the endometriomas was estimated through a transvaginal ultrasound. Analgesics (NSAIDs) intake, the serum levels of Ca125 and the desire for pregnancy were also investigated. Finally, the pregnancy rate of patients with reproductive desire was evaluated. RESULTS: One hundred and twenty patients were recruited. The intensity of dysmenorrhea, dyspareunia and CPP significantly improved (p < 0.0001). The use of NSAIDs (p = 0.001), the size of the endometriomas (p < 0.0001) and the serum levels of Ca125 (p < 0.0001) significantly decreased. Among the 52 patients with reproductive desire, 39 successfully achieved pregnancy within 6 months of starting therapy (p = 0.001). CONCLUSIONS: Oral NAC improves endometriosis-related pain and the size of endometriomas. Furthermore, it decreases Ca125 serum levels and may improve fertility in patients with endometriosis.

RESUMO

Perforation of the ileum in the antepartum period resulting in meconial peritonitis is a condition that, although rare, is burdened by several complications. In 80-90% of cases, meconial ileus is the first manifestation of a disease, cystic fibrosis. In the remaining 10-20% of cases, it is caused by other situations, such as prematurity. In most cases, the diagnosis of meconial ileus occurs after birth, although in some cases it can be suspected prenatally, with the finding of a hyperechoic intestine on second trimester ultrasound. The prognosis depends on the gestational age, the location of the obstruction and the presence of fetal abnormalities. Mortality is very high and the recovery of intestinal function in the postoperative course is very high risk. In this case series, we describe two meconial peritonitis and our experience at the center.

RESUMO

INTRODUCTION: The use of mifepristone and misoprostol for the induction of a second-trimester abortion is common and effective. However, its safety in women with previous cesarean delivery is still controversial, given the potentially higher risk of uterine rupture. CASE PRESENTATION: We present the case of a 30-year-old woman (G2P1) who experienced vesicouterine rupture with escape of the dead fetus into the bladder during second-trimester induced abortion after prior cesarean delivery. She was successfully managed with conservative surgery. CONCLUSION: This case highlights the challenges of early diagnosis of vesicouterine rupture during second-trimester medical abortion. We argue that a close monitoring of patients with prior cesarean section is mandatory, particularly if uterine contractions suddenly stop or the fetal head fails to descend. A prompt conservative surgical approach allows preservation of fertility.

RESUMO

OBJECTIVE: Combined oral contraceptives (COC) and progestogens are widely used for the treatment of endometriosis. The objective of the study is to compare the efficacy of dienogest 2 mg vs continuous oral levonorgestrel/EE (levonorgestrel 0.1 mg/ethinyl estradiol 0.02 mg) on ovarian endometriomas, deep infiltrating endometriosis (DIE), chronic pelvic pain (CPP), dyspareunia, analgesic use, quality of life (QoL), compliance and side effects. METHODS: Prospective cohort study. Two cohorts of patients with endometriosis, 50 taking dienogest (group A) and 50 taking continuous levonorgestrel/EE (group B), were evaluated at the beginning of therapy (t0), after 3 (t3) and 6 months (t6). Size of endometriomas, DIE, QoL, pain symptoms, and side effects were assessed. RESULTS: Dienogest was significantly effective on CPP (p = .002), dyspareunia (p = .021) ovarian endometriomas (p = .015) and DIE lesions reduction (p = .014). Levonorgestrel/EE was significantly effective on dyspareunia (p = .023). Analgesics consumption significantly decreased in both groups (p < .001). Both treatments significantly improved the QoL. Over 6 months a significant improvement was found, more frequently in patients taking dienogest. The only side effect that both groups complained about was vaginal bleeding, present in the first 3 months of treatment (p < .001). CONCLUSIONS: Both treatments are effective and safe for patients with endometriosis. Patients compliance and side effects are similar in both groups, however, there was a significantly higher reduction in endometriotic lesions, pain symptoms, and improvement of the QoL in women taking dienogest than in women taking continuous COC.

RESUMO

Adnexal masses are not common in pregnancy. They are often discovered incidentally during routine ultrasound examinations. In general, 24%-40% of the cases are benign tumors; up to 8% are malignant tumors. Adnexal masses are usually asymptomatic, but sometimes can be responsible for abdominal or pelvic pain. Transvaginal and transabdominal ultrasound is essential to define the morphology of pelvic masses and to distinguish between benign and malignant cases. Magnetic resonance imaging can be a complementary examination when ultrasound findings are equivocal and a useful additional examination to better define tissue planes and relations with other organs. Patient counseling can be challenging because there is no clear consensus on the management of adnexal masses during pregnancy. Treatment options consist of observational management (in case of asymptomatic women with reassuring instrumental findings) or surgery (via laparoscopy or laparotomy). Surgery can be offered as a primary tool when cancer is suspected or when acute complications such as ovarian torsion occur.

RESUMO

INTRODUCTION: Cerebral cavernomas malformations (CCMs) are vascular malformations that occur with an incidence of 0,4-0,8 % in general population. The most feared complication is cerebral hemorrhage. Currently there are no guidelines for pregnant women with CCMs. Some authors claimed that many physiological changes related to pregnancy could be linked to an high risk of rupture and bleeding of the cerebral cavernoma. However, more recent studies highlight that the presence of cerebral cavernomatosis is not a contraindication for pregnancy and that the risk of bleeding is similar in pregnant and in non-pregnant women. AIM OF THE STUDY: The purpose of our work is to analyze, through the study of controversial findings in literature, all the information currently available trying to establish a common approach for management of women with cerebral cavernomatosis in pregnancy, during childbirth and in the puerperium. FINDINGS: In accordance with existing literature, pregnancy does not appear to be a significant risk factor for the worsening of clinical manifestations associated with the presence of CCMs. Vaginal delivery is not contraindicated in patients with CCMs and there is no indication to perform cesarean section to reduce the incidence of hemorrhage. The only indication for neurosurgery of CCMs in pregnancy is the presence of rapidly progressive symptoms and should be postponed to the puerperium if arises after 30 weeks. The puerperium is a critical time for the woman with cavernomas for the possibility of bleeding and clinical observation must be continued. CONCLUSION: The patients with a diagnosis of a CCMs can have a pregnancy without any particular risk to themselves and the fetus but should be addressed to highly specialized obstetrics center to assesses the initial individual risk related to their pathology and to follow the pregnancy.

RESUMO

OBJECTIVES: The aim of this study was to evaluate obstetrical and perinatal outcomes in fetuses with short femur length diagnosed before or after 24 weeks of gestation. STUDY DESIGN: This was a prospective cohort study on singleton pregnancies with a diagnosis of fetal femur < 5 centile. Included patients were divided into two groups: patients with a first diagnosis of femur length < 5th percentile at 14-24 weeks (group A) and those with the first diagnosis made at > 24 weeks (group B). RESULTS: 147 patients were included for the analysis. Group A and group B included 66 (44.9%) and 81 (55.1%) cases. Abnormal fetal karyotype and skeletal dysplasia rates were significantly higher (27.3% vs 3.7%,P < 0.001 and 19.7% vs 3.7%, P = 0.002) in group A. Women in group B had a higher incidence of small for gestational age and intrauterine growth restriction (7.6% vs 24.7%, P = 0.007 and 19.7% vs 44.4%, P = 0.002). There was a significant higher incidence of live births in group B (34.9% vs 97.5%, P < 0.001), while the rate of termination of pregnancy was increased in group A (56.1% vs 1.2%, P < 0.001). No significant difference was found in perinatal outcomes of live births, when comparing group A and B. CONCLUSIONS: The incidence of abnormal karyotype and skeletal dysplasia is higher when short femur length diagnosed earlier in gestation, while the incidence of small for gestational age, intrauterine growth restriction and the rate of live births are significantly increased when short femur length is diagnosed later during pregnancy.

RESUMO

OBJECTIVES: To analyze the diagnostic accuracy of two-dimensional (2D) and three-dimensional transvaginal ultrasound (3D TV-US) for evaluation of parametrial status in locally advanced cervical cancer patients after neoadjuvant chemotherapy (NACT), using histology as the gold standard. METHODS: Consecutive patients with histologically confirmed cervical cancer were staged according to FIGO (International Federation of Gynaecology and Obstetrics) criteria. All IB2-IIIB FIGO stage patients were examined by 2D and 3D TV-US and magnetic resonance imaging (MRI) at the diagnosis time (T0) and after NACT. At T0, the US evaluation of parametrial involvement was compared to MRI before treatment. The results of US and MRI examinations of parametrial status after NACT were compared with the histological specimen. RESULTS: We enroled 51 consecutive patients in the study. Before chemotherapy, clinical examination under anaesthesia identified parametrial involvement in 48 patients, ultrasonography in 46 patients, and MRI in 49 patients. The agreement between US and MRI was 94%. The sensitivity of US for parametrial status was 93.8%, with a positive predictive value of 97.8%, using MRI as the standard. The correlation between US and MRI was statistically significant (p = 0). After chemotherapy, histological examination of surgical specimens identified parametrial involvement in 3 patients. Ultrasonography correctly identified those cases with parametrial infiltration, recording a sensitivity of 100%, specificity of 90.9%, positive predictive value of 50%, and negative predictive value of 100%. The MRI had a sensitivity of 100%, specificity of 45.5%, positive predictive value of 14.3%, and negative predictive value of 100%, respectively. The concordance in the identification of the presence/absence of infiltration between US and MRI with histology was 90% (p = 0.001) and 61%, respectively, after chemotherapy treatment. Particularly, in defining the degree of infiltration, the agreement between US and MRI with histology was 90 and 58%, respectively. CONCLUSION: In locally advanced cervical cancer patients, 2D/3D TV-US can be considered accurate in the evaluation of parametrial infiltration to assess the response to NACT. It could be included as a diagnostic method in the preoperative work-up of cervical cancer.

RESUMO

Fetal alcohol spectrum disorders (FASDs) are a group of negative conditions occurring in children exposed to alcohol during gestation. The early discovery of FASD is crucial for mother and infant follow-ups. In this study, we investigated in pregnant women the association between urine ethylglucuronide (EtG-a biomarker of alcohol drinking) and indicators of the physical characteristics of FASD by prenatal ultrasound in the second trimester of gestation. We also correlated these data with the AUDIT-C, T-ACE/TACER-3, TWEAK, and food habit diary, screening questionnaires used to disclose alcohol drinking during pregnancy. Forty-four pregnant women were randomly enrolled and examined for ultrasound investigation during the second trimester of gestation. Urine samples were provided by pregnant women immediately after the routine interviews. EtG determinations were performed with a cutoff established at 100 ng/mL, a value indicating occasional alcohol drinking. Fifteen of the enrolled pregnant women overcame the EtG cutoff (34.09%). Analysis of variance (ANOVA) revealed that the fetuses of the positive EtG pregnant women had significantly longer interorbital distance and also significantly increased frontothalamic distance (P's < 0.02). Quite interestingly, no direct correlation was found between EtG data and both food diary and AUDIT-C. However, a significant correlation was observed between urinary EtG and T-ACE (r = 0.375; P = 0.012) and between urinary EtG and TWEAK (r = 0.512; P < 0.001) and a concordance with all questionnaire for EtG values higher than 500 ng/mL. This study provides clinical evidence that the diagnosis of maternal alcohol consumption during pregnancy by urine EtG may disclose FASD-related damage in the fetus.

RESUMO

PURPOSE: Potential risk of adverse obstetrical outcomes has been shown among breast cancer survivors. Therefore, the aim of this systematic review and meta-analysis was to evaluate the relationship between history of breast cancer (BC) and obstetrical outcomes. METHODS: PubMed, EMBASE, and Medline were searched from the inception of each database to April 2019. Selection criteria included prospective and retrospective cohort studies of BC pregnant survivors. The meta-analysis was performed by computing odds ratios (ORs) using both fixed and random-effects models. Quality assessment of the included studies was performed using the Newcastle-Ottawa Scale and the review was registered with PROSPERO number CRD42019127716. RESULTS: Four studies, including 1466 cases of BC survivors and 6,912,485 controls, were included. Compared with controls, a higher incidence of obstetrical complication was found in women with history of BC. The incidence of preterm birth (PTB) in the study group was 11.05% compared with 7.79% in the control group (1.68, 95% confidence interval 1.43-1.99). Breast cancer history was also associated with low birth weight (LBW) (study group: 9.26% vs. control group: 5.54%, 1.88, CI 95% 1.55-2.27), cesarean section (CS) (study group: 19.76% vs. control group 10.81%, 1.78, CI 95% 1.39-2.27), intrauterine fetal death (IUFD) (study group: 0.004% vs. control group 0.36%, of 1.25 CI 95% 0.36-4.35), and fetal anomalies (study group: 5.8% vs. control group: 4.26%, 1.45 CI 95% 1.01-2.09). CONCLUSIONS: History of BC was associated with adverse obstetrical outcomes.

RESUMO

The aim of the present study was to evaluate the effect of laparoscopic cystectomy on ovarian reserve by means of anti-Müllerian hormone (AMH) serial measurements and to compare AMH values with the number of inadvertently removed follicles in histological specimens. Fifty-two women were enrolled: 34 patients with endometriomas (group 1) and 18 patients with other benign ovarian cysts (group 2). All patients underwent laparoscopic cystectomy performed by a single experienced surgeon. The AMH was measured before, and 1, 3, and 6 months after cystectomy in group 1, and before and 6 months after surgery in group 2. Preoperative AMH levels (mean [standard deviation, SD]) in group 1 (3.39 [2.43] ng/mL) were not significantly different from group 2 (3.74 [2.57] ng/mL; P = .68). In group 1, a significant decrease in AMH levels of 43.4% was observed at 1 month (1.93 [1.36]; P = .003), and of 63.1% at 3 months (1.25 [1.00]; P = .007) postoperatively. The AMH increased not significantly between the third and sixth months in group 1 (+9.4%). Six months after surgery, AMH was reduced by 59.3% compared to baseline values in group 1 (P = .012), and by 29.5% in group 2 (P = .200). A significant difference in the AMH decrease was present between bilateral and monolateral endometriomas (P = .006). There was no correlation between the reduction rate of AMH and the number of follicles inadvertently removed in patients with endometriomas (P = .669). In conclusion, AMH decreases significantly after surgical excision of ovarian endometriomas. The postoperative decrease does not appear to correlate with the amount of ovarian tissue inadvertently excised with the endometrioma wall.

RESUMO

It is nowadays widely accepted that some tumors have a niche of cells endowed with stemness features, which may cause resistance to conventional anticancer therapies and relapse/recurrence of the malignancy. These cells are usually referred to as cancer stem cells (CSCs) and, different from normal cancer cells, are rather quiescent. Targeting CSCs is thus a highly challenging but promising strategy to counteract tumor growth, and to develop innovative anticancer agents. Here, we review the chemical, biological and multidisciplinary efforts that have been spent in targeting CSCsspecific signaling pathways Notch and Hedgehog (Hh) for anticancer drug discovery. In particular, the use of natural products as a valuable source of lead compounds or chemical biology tools is emphasized. Examples of natural products functionalization through semi-synthetic transformations or total syntheses, aimed at improving pharmacokinetics and/or pharmacodynamics properties of natural products in Notch or Hh inhibition, are provided as well.

RESUMO

INTRODUCTION: Two different types of vulvar intraepithelial neoplasia (VIN), HPV-related and HPV-unrelated, should be considered as two separate entities with different management options. The incidence of HPV-related VIN is increasing worldwide and is implicated in carcinogenesis. Our objective is to investigate the use of p16INK4a immunostaining or p16INK4a/p53 double staining for the detection of HPV-related disease to overcome the problem that histological criteria often have significant overlap. METHODS: A systematic literature search was carried out in the online databases PubMed, EMBASE, Cochrane Library, Clincaltrials.gov and Scopus. The key search terms were HPV, VIN, p16INK4a immunochemistry and p53. RESULTS: We found that nuclear and cytoplasmic immunostaining for p16INK4a was intense and diffuse in HPV-associated lesions and weak and focal in normal vulvar epithelium, nondysplastic lesions, lichen sclerosus and keratinizing vulvar squamous cell carcinoma. p53 nuclear immunostaining was always negative in HPV-related disease. CONCLUSIONS: Our findings indicated that p16INK4a or p16INK4a/p53 immunoreactivity, along with histological diagnosis, could be a convenient means to adequately classify VIN and its connection to HPV infection. Therefore, the clear recognition of HPV-associated VIN would lead to an appropriate strategy of treatment and follow-up.

RESUMO

PURPOSE: To compare sonohysterosalpingography (sono-HSG) with foam instillation (HyFoSy) versus saline solution (HyCoSy) in the evaluation of tubal patency. METHODS: We prospectively enrolled 37 infertile women, scheduled for laparoscopy. The women were randomized into two groups: HyFoSy (group I) and HyCoSy (group II). The patients of both groups underwent laparoscopy with dye test. We assessed the diagnostic performance (sensitivity, specificity, and overall accuracy) of HyFoSy and HyCoSy, compared with laparoscopy and dye test, in the assessment of tubal patency. RESULTS: Sono-HSG findings in tubal patency assessment obtained in the HyFoSy group were concordant with laparoscopic results in 94.4% of cases, with a sensitivity of 87.5% and a specificity of 100%, whereas in the HyCoSy group, concordance occurred in only 57.8% of examinations, with a sensitivity of 50% and a specificity of 66.6%. CONCLUSIONS: HyFoSy allows a more accurate diagnosis of tubal patency compared with HyCoSy. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 45:67-71, 2017.

RESUMO

This systematic review focuses on the literature evidence for residual ovarian function during treatment with hormonal contraceptives. We reviewed all papers which assessed residual ovarian activity during hormonal contraceptive use, using endocrine markers such as serum anti-Müllerian hormone (AMH) concentrations, FSH, LH, oestradiol, progesterone and sonographic markers such as antral follicle count (AFC), ovarian volume and vascular indices. We considered every type (oestroprogestin or only progestin) and dosage of hormonal contraceptive and every mode of administration (oral, vaginal ring, implant, transdermal patch). We performed an electronic database search for papers published from 1 January 1990 until 30 November 2015 using PubMed and MEDLINE. We pre-selected 113 studies and judged 48 studies suitable for the review. Most studies showed that follicular development continues during treatment with hormonal contraceptives, and that during treatment there is a reduction in serum concentrations of FSH, LH and oestradiol, and also a reduction in endometrial thickness, ovarian volume and the number and size of antral follicles. The ovarian reserve parameters, namely AFC and ovarian volume, are lower among users than among non-users of hormonal contraception; regarding the effect of hormonal contraception on AMH, there are still controversies in the literature.

RESUMO

PURPOSE: In a retrospective observational study, we evaluated the feasibility and safety of medical therapy with transabdominal ultrasound-guided injection of methotrexate (MTX) into the gestational sac (GS) in patients with interstitial ectopic pregnancies. METHODS: Fourteen interstitial ectopic pregnancies were treated with transabdominal ultrasound-guided injection of MTX (25 mg). All patients were hemodynamically stable. In all patients, the 10-cm distance between the GS and vaginal fornices was ≥10 cm, making transvaginal injection difficult. To evaluate feasibility and safety of the procedure, we assessed complications clinically and with imaging during a 1-year follow-up. RESULTS: In all 14 patients, MTX injected locally into the GS successfully terminated the interstitial pregnancy, thereby avoiding surgery. There was no complications during follow-up. CONCLUSIONS: The successful outcome in our patients suggests that the transabdominal route is feasible and safe as a nonsurgical option for terminating an ectopic interstitial pregnancy in patients in whom the transvaginal route is contraindicated or difficult, provided the patients are properly selected and operators have sufficient experience with the technique.

RESUMO

BACKGROUND: Aim of this prospective, case-control study was to evaluate uterine arteries' blood flow before and after laparoscopic surgery in patients with ovarian endometriosis and its possible correlation with infertility. METHODS: We prospectively enrolled 110 women of reproductive age; 69 with ovarian endometriomas and scheduled for surgery, and 41 controls. At enrolment, a detailed medical, gynecologic and obstetric history was collected. Fertility and pregnancy desire were assessed. All patients underwent complete physical and gynecologic examination. Transvaginal ultrasound with Doppler color flow was performed to evaluate Resistance Index (RI) of uterine arteries during the secretory phase, at enrolment (T0) and 3 months after laparoscopic surgery (T1). RESULTS: Among cases, 27 patients were excluded because they did not meet the inclusion criteria. At enrolment (T0) unilateral or bilateral flow alterations (RI ≥ 0.8) were found in 38 out of 42 patients with ovarian endometriosis (90%), whereas in the control group only 17 women (41%) had Doppler alterations. The difference in uterine artery RI values between cases and controls was statistically significant (P < 0.0001). A statistically significant improvement in uterine artery flow (P <0.0001) was found 3 months after surgical treatment of endometriosis. Nineteen patients with endometriosis (45%) were infertile before surgery; all of them presented uterine artery Doppler alterations at T0. After surgery the pregnancy rate was significantly higher in patients who presented uterine artery flow normalization than in those with persistent uterine artery flow alterations (p = 0.002). CONCLUSIONS: A strong correlation was found between uterine artery flow abnormalities and ovarian endometriosis. Uterine artery flow improvement following surgery seems to increase the probabilities of achieving pregnancy.
