Multilevel musculo-fascial defect magnetic resonance study of female pelvic floor: retrospective case control study in women with pelvic floor dysfunction after the first vaginal delivery.

INTRODUCTION: Magnetic resonance imaging (MRI) provides a detailed display of the pelvic floor structures responsible for normal pelvic floor anatomy. The aim of the study is to assess the appearance of musculo-fascial defects in women with pelvic floor dysfunction following first vaginal delivery. MATERIAL AND METHODS: Analysis of axial T3 (Tesla 3) MRI scans from a case control study of symptomatic (n = 149) and asymptomatic (n = 60) women after first vaginal delivery. Presence and severity of pelvic organ support and attachment system defects in three axial pelvic planes were assessed. RESULTS: In the symptomatic group, major muscular defects were found in 67.1% (for pubovisceral muscle complex) and 87.9% (for iliococcygeal muscle). Only 6.7% of major pubovisceral and 35.0% of major iliococcygeal defects were identified in the controls (p = 0.000). Prolapse patients had an odds ratio (OR) of 22.1 (95% CI 8.94-54.67) to have major pubovisceral muscle complex defect and OR of 4.9 (95% CI 1.51-15.71) to have major iliococcygeal muscle defect. Fascial defects were found in 60.4% and 83.2% the symptomatic group, respectively. Those with prolapse had an OR of 29.1 (95% CI 9.77-86.31) to have facial defect at the level of pubovisceral muscle complex and an OR of 16.9 (95% CI 7.62-37.69) to have fascial defect at the level of iliococcygeal muscle. Uterosacral ligaments detachment was associated with prolapse with an OR of 10.1 (95% CI 4.01-25.29). For the model based on combination on all MRI markers, the area under the receiver operating characteristic curve is 0.921. CONCLUSIONS: This study provides comprehensive data about first vaginal delivery-induced changes in the levator ani muscle and endopelvic fascial attachment system. These changes are seen also in asymptomatic controls, but they are significantly less expressed.

Telemedicine in prenatal care.

Telemedicine, as a health service provided remotely, is increasingly becoming a common part of health care. Telemedicine is defined as "an umbrella term for health activities, services and systems operated remotely through information and communication technologies to promote global health, prevention and health care, as well as education, health management and health research". It also describes telemedicine as "the provision of services where distance is a critical factor, using information and communication technologies to exchange valid information for the diagnosis, treatment and prevention of disease and injury, for research and evaluation, and for the continuing education of healthcare providers to improve the health of individuals and communities". Both definitions imply that two of the hallmarks of telemedicine include the use of communication and information technologies to overcome distance as a critical factor, a factor that is well known to us, not least from the recent months of the COVID-19 pandemic. Distance medicine can thus act as a tool for improving access to health care and also complement health care itself in a very appropriate way.

Role of umbilical interleukin-6, procalcitonin and C-reactive protein measurement in the diagnosis of fetal inflammatory response syndrome.

OBJECTIVE: Fetal Inflammatory Response Syndrome (FIRS) is a serious complication accompanied by increased neonatal mortality and morbidity. Early dia-gnosis of FIRS is essential to detect high risk infants. The aim of the study was to evaluate the correlation between interleukin-6 (IL-6), procalcitonin (PCT), C-reactive protein (CRP) in cord blood and histologically proven funisitis;chorioamnionitis in high-risk infants after preterm birth. METHODS: Blood sampling for the measurement of inflammatory bio-markers was performed immediately after placental delivery and umbilical cutting. Umbilical and placental inflammatory changes were assessed using a recently released scoring system (Amsterdam Placental Workshop Group Consensus). RESULTS: One hundred preterm infants (30.5 ± 2.5 gestational week, birth weight 1,443 ± 566 grams) and 21 health term infants were analyzed. Histologic chorioamnionitis was confirmed in 19% cases and chorioamnionitis with funisitis in 7% cases. Thirty-three infants (33%) fulfilled criteria of FIRS (funistis and/ or umbilical IL-6 > 11 ng/ L). The presence of FIRS correlated significantly with maternal leukocytosis (P < 0.001), preterm premature rupture of membrane (P < 0.001) and preterm uterine contraction (P < 0.0001). In comparison to preterm and healthy term infants we found statistically significant higher levels of umbilical inflammatory bio­markers (IL-6, PCT, CRP) in FIRS group (P < 0.0001). Composite mortality and morbidity (bronchopulmonary dysplasia, intraventricular haemorrhage, periventricular leukomalacia) was higher in FIRS group (28.1 vs 22.4% in preterm group). However, the difference was not statistically significant (P = 0.53). CONCLUSION: Our study confirmed the correlation of umbilical inflammatory bio­markers levels (IL-6, PCT, CRP) and the presence of FIRS. We did not find significant adverse impact of FIRS on neonatal mortality and morbidity. Nevertheless, our results could be influenced by the size of study group and strict inclusion criteria (only cases after C-section were analyzed).

Persistent occiput posterior position and stress distribution in levator ani muscle during vaginal delivery computed by a finite element model.

INTRODUCTION AND HYPOTHESIS: Objective of this study was to develop an MRI-based finite element model and simulate a childbirth considering the fetal head position in a persistent occiput posterior position. METHODS: The model involves the pelvis, fetal head and soft tissues including the levator ani and obturator muscles simulated by the hyperelastic nonlinear Ogden material model. The uniaxial test was measured using pig samples of the levator to determine the material constants. Vaginal deliveries considering two positions of the fetal head were simulated: persistent occiput posterior position and uncomplicated occiput anterior position. The von Mises stress distribution was analyzed. RESULTS: The material constants of the hyperelastic Ogden model were measured for the samples of pig levator ani. The mean values of Ogden parameters were calculated as: µ1 = 8.2 ± 8.9 GPa; µ2 = 21.6 ± 17.3 GPa; α1 = 0.1803 ± 0.1299; α2 = 15.112 ± 3.1704. The results show the significant increase of the von Mises stress in the levator muscle for the case of a persistent occiput posterior position. For the optimal head position, the maximum stress was found in the anteromedial levator portion at station +8 (mean: 44.53 MPa). For the persistent occiput posterior position, the maximum was detected in the distal posteromedial levator portion at station +6 (mean: 120.28 MPa). CONCLUSIONS: The fetal head position during vaginal delivery significantly affects the stress distribution in the levator muscle. Considering the persistent occiput posterior position, the stress increases evenly 3.6 times compared with the optimal head position.

Ultrasound cesarean scar assessment one year postpartum in relation to one- or two-layer uterine suture closure.

INTRODUCTION: This study compared healing of the scars after cesarean section during the first postpartum year using a single- or double-layer suturing technique. Scarring was assessed by a transvaginal ultrasound. We explored the appearance and localization of uterine scars with regard to the obstetric history. Our aim was to compare the position of the scar or defect, if present, its dimensions, and any residual myometrium with respect to the suturing technique during the cesarean section. MATERIAL AND METHODS: Women with uncomplicated singleton pregnancies indicated for elective or acute cesarean section were randomly allocated to the uterine closure technique group. During the first postpartum year, their lower uterine segment was examined with a transvaginal ultrasound in three consecutive visits at 6 weeks, 6 months and 12 months. RESULTS: 324 women attended the 12-month visit; of these, 149 underwent single-layer closure of the uterine incision and 175 double-layer technique. A higher proportion of the defects is seen in the single-layer closure technique of suturing. Defects in the single-layer group were wider (0.002) and the residual myometrial thickness in the single-layer group were thinner (0.019). Women who underwent cesarean section at the stage of full cervical dilation had scars that were closer to the external cervical os (0.000). The position of the uterus varies greatly between controls (0.000). The combination of uterine position and scar defect presence changed significantly between controls (0.001), and was significantly dependent on the suturing method (0.003). Defects with or without contact with the uterine cavity changed statistically between controls (0.017). Both types of defects were more common in the single-layer closure technique group. CONCLUSIONS: The findings of this study demonstrate that double-layer technique with the first continuous nonlocking suture followed by a second continuous nonlocking suture is associated with better suture healing and greater residual myometrial thickness. No difference was observed between single- and double-layer closure for the presence of maternal infectious morbidity, wound infection or blood transfusion.

Complications of planned home births in the Czech Republic between 2016‒2017.

OBJECTIVE: This study aimed to analyze the complications of planned home births treated at healthcare facilities in the Czech Republic. METHODS: This prospective cohort observational study is based on analysis of women hospitalized with complications related to planned home deliveries in the Czech Republic between 2016 and 2017. The data were collected using an online form made accessible to the directors of all maternity hospitals in the Czech Republic. The results were statistically evaluated. RESULTS: We identified 45 complications during planned home deliveries. Complications occurred most often among women living in largely populated cities with higher levels of education. Overall, 40% of patients did not receive routine antenatal care, and 38% of women gave birth after the 41st week of pregnancy. In 60% of cases, no professionals attended the birth. Hospital transfer frequencies were 42% after delivery, 36% at third-stage labour, 11% first-stage labour, 9% second-stage labour, and 2% before delivery. We recorded four neonatal deaths and one severe newborn morbidity. There was one maternal death unrelated to the home-birthing process and six cases of severe maternal haemorrhagic shock requiring intensive care. CONCLUSION: Complications of planned home births occurred more frequently in women living in largely populated cities and with higher education levels. Planned home births were also observed among women who were at a higher risk of complications. Risk factors included nulliparity, postdate pregnancy, and lack of prenatal care. Hospital transfers occurred most often in the third stage of labour and postpartum.

The effect of the first vaginal birth on pelvic floor anatomy and dysfunction.

INTRODUCTION AND HYPOTHESIS: First vaginal delivery severely interferes with pelvic floor anatomy and function. This study determines maternal and pregnancy-related risk factors for pelvic floor dysfunction (PFD), including urinary incontinence (UI), urgency, anal incontinence (AI), pelvic organ prolapse (POP) and levator ani muscle (LAM) avulsion. METHODS: This is a single-centre prospective observational cohort study on healthy women in their first singleton pregnancy. All underwent clinical and 3D transperineal ultrasound examination at 6 weeks and 12 months postpartum. Objective outcomes were POP-Q and presence or absence of LAM trauma. Functional outcomes were measured by the ICIQ-SF and PISQ 12. Multivariate regression was performed to determine birth and maternal habitus-related risk factors for UI, urgency, AI, dyspareunia, LAM avulsion and ballooning. RESULTS: Nine hundred eighty-seven women were included. Risk factors for UI were maternal age per year of age (OR: 1.09; 95% CI: 1.04-1.13; p = 0.0001) and BMI before pregnancy (OR: 1.08; 95% CI: 1.04-1.13; p = 0.001); for POP stage II+ maternal age (OR: 1.08; 95% CI: 1.08-1.14; p = 0.005). Avulsion was more likely after forceps (OR: 3.22; 95% CI:1.54-8.22; p = 0.015) but less likely after epidural analgesia (OR: 0.58; 95% CI: 0.37-0.90; p = 0.015) and grade I perineal rupture (OR: 0.50; 95% CI: 0.29-0.85; p = 0.012). Ballooning was more likely at increased maternal age (OR: 1.08; 95% CI: 1.02-1.13; p = 0.005), epidural (OR: 1.64; 95% CI: 1.06-2.55; p = 0.027) and grade I perineal rupture (OR: 1.79; 95% CI: 1.10-2.90; p = 0.018). CONCLUSION: Though maternal characteristics at birth such as age or BMI increase the risk of PFD, labour and birth factors play a similarly important role. The most critical risk factor for MLA avulsion was forceps delivery, while an epidural had a protective effect.

Interposition of the mesorectal flap as prevention of rectovaginal fistula in patients with endometriosis.

INTRODUCTION AND HYPOTHESIS: Endometriosis is a gynecological condition characterized by endometrial tissue outside of the uterus. It affects up to 15% of women of reproductive age. In the case of bowel infiltration, about 90% of lesions are localized on the sigmoid colon or the rectum and may interfere with bowel function. Three surgical approaches are possible: (1) shaving technique, (2) discoid resection of the nodule, and (3) segmental resection with end-to-end anastomosis. A rectovaginal fistula is feared as a postoperative complication mainly in simultaneous resection of the vaginal and the rectosigmoid nodules. Its prevention is a two-step surgery (the first operation on the vagina and the second on the colon) or a preventive colostomy, both of which are often thought to be too invasive for a benign condition. Herein, we suggest a one-step surgery to prevent its development. METHODS: In three women, a concomitant laparoscopic resection of the vaginal and rectosigmoid endometrial nodule was completed with interposition of a mesorectal flap. RESULTS: All surgeries were uncomplicated with no rectovaginal fistula in the postoperative period. CONCLUSION: In the hands of skilled surgeons, this one-step technique can be used to prevent rectovaginal fistula development.

Finite element model focused on stress distribution in the levator ani muscle during vaginal delivery.

INTRODUCTION AND HYPOTHESIS: During vaginal delivery, the levator ani muscle (LAM) undergoes severe deformation. This stress can lead to stretch-related LAM injuries. The objective of this study was to develop a sophisticated MRI-based model to simulate changes in the LAM during vaginal delivery. METHODS: A 3D finite element model of the female pelvic floor and fetal head was developed. The model geometry was based on MRI data from a nulliparous woman and 1-day-old neonate. Material parameters were estimated using uniaxial test data from the literature and by least-square minimization method. The boundary conditions reflected all anatomical constraints and supports. A simulation of vaginal delivery with regard to the cardinal movements of labor was then performed. RESULTS: The mean stress values in the iliococcygeus portion of the LAM during fetal head extension were 4.91-7.93 MPa. The highest stress values were induced in the pubovisceral and puborectal LAM portions (mean 27.46 MPa) at the outset of fetal head extension. The last LAM subdivision engaged in the changes in stress was the posteromedial section of the puborectal muscle. The mean stress values were 16.89 MPa at the end of fetal head extension. The LAM was elongated by nearly 2.5 times from its initial resting position. CONCLUSIONS: The cardinal movements of labor significantly affect the subsequent heterogeneous stress distribution in the LAM. The absolute stress values were highest in portions of the muscle that arise from the pubic bone. These areas are at the highest risk for muscle injuries with long-term complications.

Complications in right-sided paraaortic lymphadenectomy: ventral tributaries of the inferior vena cava.

The purpose of this study was to describe the distribution and structure of ventral tributaries leading into the inferior vena cava where right-sided paraaortic lymphadenectomy is performed. The study examined 21 retroperitoneal specimens by graphic reconstruction, statistical evaluation, and histological examination of ventral tributaries (VTs). Seventy VTs were identified. The average number per specimen was 3.33. There were 20, 40, and 40% of VTs found in Levels I, II, and III, respectively. During the preparation, we observed an unusual arrangement of the IVC wall, into which VTs were led through a preformed sleeve-like channel and anchored near the lumen. This finding is a key mechanism that explains the ease with which VTs are extracted during surgery. Knowledge of the distribution and histological structure of VTs allows proper orientation of the retroperitoneal area of the front wall of inferior vena cava, which is essential for uncomplicated right-sided paraaortic lymphadenectomy. The histological structure of the VT ostium within the wall of the inferior vena cava explains why injury is easy during the procedure.

Complications of planned home births in the Czech Republic.

OBJECTIVES: This study evaluated complications that can occur during planned home births that require transfer to the hospital. These factors were assessed to improve the current status of deliveries performed outside health care facilities in the Czech Republic. MATERIALS AND METHODS: This prospective cohort study included data on 105 cases of complicated home births during 2017 to 2021 using an online form accessible to all hospital maternity wards in the Czech Republic. RESULTS: Planned home births were complicated by fetal/neonatal causes, maternal causes, and combined fetomaternal complications in 28 (26.7%), 20 (19%), and 2 (1.9%) cases, respectively. The need for transfer was most often realized after the birth of the fetus (86; 81.9%); however, it was realized during birth in 19 (18.1%) cases. The following complications were noted most often: postpartum hemorrhage (23; 21.9%); neonatal asphyxia (17; 16.2); placental retention (14; 13.3%); birth injury (12; 11.4%); neonatal hypothermia (5; 4.8%); and placental birth (5; 4.8%). Indications for transfer during labor were as follows: labor obstruction (10; 9.5%); fetal hypoxia (5; 4.8%); bleeding during labor (2; 1.9%); preeclampsia (1; 0.9%); and fetal malformation (1; 0.9%). Perinatal death occurred in 8 (7.6%) cases. Permanent neonatal morbidity occurred in 4 (3.8%) cases. CONCLUSIONS: Patients with home birth complications were transferred to the hospital most often after the birth of the fetus. The low proportion of transfers during childbirth is caused by the unprofessional management of planned home births, resulting in a high number of perinatal deaths and high rate of permanent neonatal morbidity.

A severe case of pemphigoid gestationis persisting after labour - case report and review of the literature.

BACKGROUND AND AIM: Pemphigoid gestationis (PG) is a rare skin disease of pregnancy. Given its incidence in pregnant women, physicians and especially obstetricians may not encounter this diagnosis in their entire career. We find this to be a major problem and there is an obligation to report it in as much detail as possible along with recommended treatments with proven efficacy. CASE REPORT: We describe the case of a 27 year old patient who was referred to the dermatology department with severe dissemination of blisters in the 9th week of pregnancy. She was diagnosed with pemphigoid gestationis in her first pregnancy. High doses of corticosteroids were initiated but due to inadequate effect cyclosporine was added. The pregnancy was complicated with gestational diabetes. The patient gave birth in her 33rd week by caesarian section due to premature rupture of the membrane. Vesicles were seen on the newborn immediately after birth which diminished spontaneously over 2 weeks. Blisters were still seen on the patient 1 month after labor even with the combination of systemic corticosteroids with cyclosporine. CONCLUSION: PG is a rare dermatosis of pregnancy. The course of the disease can be severe, necessitating systemic therapy. As described in this patient, systemic corticosteroids may not be sufficient and adding another immunosuppressive treatment may be needed. If pemphigoid gestationis has occurred during a previous pregnancy it is advised to reconsider another pregnancy.

In vitro simulation of acute feto-fetal transfusion in case of single intrauterine fetal death in monochorionic twins.

INTRODUCTION: Thanks to shared circulation in monochorionic twins, single intrauterine fetal death (IUD) may lead to acute feto-fetal transfusion (aFFTR). The objective of the study was to describe our model of aFFTR simulation after IUD in monochorionic (MC) twins. METHODS: Prospective study analyzed 99 fresh MC placentas with the physiological course. A specially designed protocol was used for the preparation and analysis of the placentas. A pair of infusion sets fixed together using a mechanical mercury sphygmomanometer cuff was connected to the cannulated umbilical arteries. The tonometer was pressurized up to 30 and 40 mmHg. A positive finding of aFFTR was determined as the amount exceeding 1 ml of dye flowed out of the umbilical cord simulating a dead fetus. The number and types of anastomoses, types, and distances between cords insertions, and the size of the placental areas for each fetus were also statistically analyzed. The placental angioarchitecture with and without proven aFFTR was statistically compared, odds ratio (OR) and multivariable logistic analysis were performed. RESULTS: A total of 49/99 (49.5%) cases of aFFTR was proven, and the average transfusion time of 1 ml was 30 s (19-46 s). aFFTR was present in 49/78 (62.8%) of placentas with arterio-arterial (AA) anastomosis. The median diameter of AA anastomoses with the present, and absent aFFTRF was 2.0 mm and 1.0 mm, respectively. The proven interfetal transfusion was 8%, 31%, and 61% in AA anastomoses with a diameter below 0,5 mm, 0,5-1,5 mm, and above 1,5 mm, respectively (p < 0,001). AA anastomoses diameter >1.5 mm had OR of 44.2 (95% CI 5.54-352.39). In the case of coexistence of AA anastomosis and umbilical cord distance ≤5th percentile, the aFFTRF occurred in 90.9%. DISCUSSION: The potential risk of aFFTR in monochorionic twins is mainly due to the presence and nature of AA anastomoses. The diameter and length of the vessels play a crucial role, which is clinically related to the distance of the umbilical cords insertions.

Peripartum rupture of renal artery aneurysm - case report.

We present a case of silent rupture of the renal artery aneurysm in a pregnant woman brought to the maternity hospital in shock. Renal artery aneurysms (RAA) are rare and account for 0.01-0.5% of all aneurysms with an incidence of approximately 0.09%. Rupture of the renal artery aneurysm is a rare and severe complication associated with extremely high morbidity and mortality in both mother and fetus. Thanks to the improvement and effectiveness of medical care in the 21st century, fetal mortality decreased by 70-80%, and 60-70 % for the mother. The essence of a successful management of this serious, life-threatening condition is a close cooperation between obstetricians, midwives, anesthesiologists, general surgeons, and vascular surgeons.

TVT-S for surgical treatment of stress urinary incontinence: prospective trial, 1-year follow-up.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to evaluate the effectiveness of and morbidity associated with the tension-free vaginal tape-secur (TVT-S) procedure in women with stress urinary incontinence (SUI). METHODS: We performed a prospective trial, examining 86 women with primary SUI. Eighty-two patients had a 1-year follow-up (dropout rate = 4.6%). The preoperative evaluation included urinalysis, urodynamic studies, and validated questionnaires. The 1-year outcome evaluation also included a 1-h pad testing. RESULTS: At the 1-year follow-up, 43 (52.4%) women were objectively cured, and 14 (17.1%) women were objectively improved. Subjectively, 49 (59.7%) patients did not experience urine loss, and 18 (22.2%) women improved in this respect. Postoperative de novo urge incontinence symptoms developed in 24.4% (n = 20) of patients. Vaginal defect healing occurred in 6.1% (n = 5) of patients, and one (1.2%) case of urethral erosion was reported. CONCLUSION: Objective and subjective cure rates following TVT-S are inferior to other tape procedures.

TVT and TVT-O for surgical treatment of primary stress urinary incontinence: prospective randomized trial.

INTRODUCTION AND HYPOTHESIS: A study was conducted to compare the efficacy and complications of TVT and TVT-O. METHODS: This study is a prospective randomized trial involving 300 women with primary SUI; 149 received TVT, and 151 patients were treated with TVT-O. At the 1 year follow-up, 141 TVT patients and 147 TVT-O patients (dropout, 5.3% and 2.6%) were evaluated using urodynamic studies, validated questionnaires, and a 1-h pad test. RESULTS: The mean operating time was shorter in the TVT-O group (p < 0.001). Urinary retention was not significantly different (p > 0.05). Inner thigh discomfort was reported by 5.4% of TVT-O patients. In the TVT and the TVT-O groups, respectively, 90.1% and 88.4% women were objectively cured. The satisfaction with the surgical outcome reflects the significant decrease in the questionnaire mean symptom scores in both groups. Postoperative de novo urgency was significantly more common in the TVT-O patients (p = 0.015). CONCLUSION: The groups showed comparable objective and subjective cure rates.

Prenatal three-dimensional sonographic findings associated with annular pancreas.

Annular pancreas is a rare developmental anomaly that accounts for 1% of neonatal intestinal obstructions. For the first time, we describe 3D sonographic findings associated with this condition. In addition to stringent diagnostic criteria based on 2D ultrasound, this case suggests the possible contribution of 3D ultrasound in rare cases of suspected annular pancreas. Verification of prenatal findings was performed during the postnatal surgery.

Assessment of endometrial and ovarian characteristics using three dimensional power Doppler ultrasound to predict response in frozen embryo transfer cycles.

OBJECTIVE: To evaluate whether endometrial or ovarian parameters as measured using 3D power Doppler ultrasound would predict the outcome in frozen embryo transfer (FET) cycles. METHODS: Thirty women with no known gynecological pathology undergoing FET were recruited. The FET was carried out in the natural menstrual cycle 3-4 days after the first positive LH test result. Blood samples for hormonal analysis were collected, and three-dimensional (3D) ultrasonographic examination was performed on the day of the FET and repeated with analysis of the total hCG one week later. RESULTS: The demographic, clinical, and embryological characteristics were similar between the pregnant (15/30) and nonpregnant groups (15/30). There were no differences between the groups in endometrial/subendometrial thickness, volume, or vascularization index (VI). The endometrial triple-line pattern was more often present in the pregnant group on the day of the FET (93.3% vs. 40.0%, 95% CI 25.5-81.2%). No differences in the ovaries were observed on the day of the FET. At the second visit, the triple-line pattern was still more often present in those patients who had conceived (91.7% vs. 42.9%, 95% CI 18.5-79.1%), and their corpus luteum was more active as judged by the rise in 17-hydroxyprogesterone and estradiol levels. No differences were observed in the dominant ovarian vasculature. CONCLUSIONS: According to our results, measurement of power Doppler indices using 3D ultrasound on the day of the FET does not provide any additional information concerning the outcome of the cycle. The existence of the triple-line pattern on the day of the FET seems to be a prognostic sign of a prosperous outcome after FET. The dominant ovary in the pregnant group seems to be already activated one week after the FET.

Conservative management in three cases of prenatally recognized splenic cyst using 2D, 3D, multi-slice and Doppler ultrasonography.

The aetiology, differential diagnosis and management strategies of the foetal spleen affected with a cystic lesion are discussed. In the current literature, there are very few reports that relate to antenatally diagnosed splenic cyst. Our study presents 3 case reports that were first suspected due to anisoechogenic structures detected during routine ultrasonographic examination at the 27th, 31st and 34th weeks of gestation. All 3 cases were further characterized by the lack of pathological power Doppler findings inside and around the lesions, and were morphologically refined by prenatal 3D ultrasound imaging. All findings were reconfirmed postnatally. No complications such as cyst expansion, subcapsular bleeding or acute abdomen have developed, and all 3 cystic lesions have regressed spontaneously after birth.

Endopelvic fascia in women: shape and relation to parietal pelvic structures.

OBJECTIVE: The endopelvic fascia is a confluent suspensory apparatus of the female pelvic organs. The aim of the study was to construct a three-dimensional model of the endopelvic fascia, defining its shape and its connections to the surrounding parietal structures. METHODS: We created a three-dimensional multiple-source computer model to simultaneously visualize and analyze all the structures within the female pelvic floor. This model integrates data from magnetic resonance imaging of 15 nulliparas under age 30 with no symptoms of pelvic floor dysfunction. The model also includes data from direct observation in the dissection laboratory and in surgical rooms, together with the relevant scientific literature. RESULTS: The endopelvic fascia has the shape of a semifrontally oriented septum, which surrounds the vagina and part of the uterine cervix and divides the pelvic floor into the anterior and posterior compartments. This confluent septum has specific connections to the pubic bone, anterior perineal membrane, perineal body, and superior fascia of the levator ani muscle. Additionally, the uterosacral part of the septum has three subdivisions- the "vascular part," the "neural part," and the true uterosacral ligament. Each of these subdivisions has a different physical link to the parietal structures. Three-dimensional illustrations and schemes were created to facilitate the understanding of the anatomy of these complex structures. CONCLUSION: Connecting descriptions of the geometry of the organs visible by magnetic resonance imaging with descriptions of their individual connections to the endopelvic fascia gave us unique information about the three-dimensional representation of the anatomy of the female lesser pelvis. The endopelvic fascia divides the lesser pelvis in a manner that is similar to the way the urorectal septum divides the embryonic cloaca.
