Pregnancy in a non-communicating rudimentary horn of a unicornuate uterus.

BACKGROUND: The non-communicating rudimentary horn of a unicornuate uterus is the rare result of abnormal development of the Müllerian ducts during embryogenesis.  Case description: We report a rare condition of a pregnancy of eight weeks of gestation in a non-communicating rudimentary horn of a unicornuate uterus, which was diagnosed without specific symptoms and treated through laparoscopy. CONCLUSION: Early diagnosis and treatment are essential to prevent the high maternal risk of life-threatening bleeding complications. HIPPOKRATIA 2019, 23(2): 92-94.

Quality Requirements for the early Fetal Ultrasound Assessment at 11-13+6 Weeks of Gestation (DEGUM Levels II and III).

The early fetal ultrasound assessment at 11 - 13(+6) weeks of gestation remains the cornerstone of care despite the progress in diagnosing fetal chromosomal defects using cell-free fetal DNA (cffDNA) from the maternal circulation. The measurement of nuchal translucency (NT) allows the risk calculation for the fetal trisomies 21, 18 and 13 but also gives information on those fetal chromosomal defects which are at present unable to be detected using cffDNA. Nuchal translucency is the only auditable parameter at 11 - 13(+6) weeks and gives thus information on the quality of the first trimester anomaly scan. In addition it gives indirect information on the risks for fetal defects and for cardiac anomalies. Also the chances for a healthy live baby can be estimated. As experience with first trimester anomaly scanning increases, and the resolution of the ultrasound equipment has increased substantially, more and more details of the fetal anatomy become accessible at the first trimester scan. Therefore fetal anatomical defects and complex anomalies have become amenable to examination in the first trimester. This guideline describes compulsory and optional parameters for investigation at the first trimester scan and outlines a structured method of examining a first trimester fetus at 11 - 13(+6) weeks of gestation.

Cranial and cerebral signs in the diagnosis of spina bifida between 18 and 22 weeks of gestation: a German multicentre study.

OBJECTIVE: The aim of this article is to study secondary cranial signs in fetuses with spina bifida in a precisely defined screening period between 18 + 0 and 22 + 0 weeks of gestation. METHOD: On the basis of retrospective analysis of 627 fetuses with spina bifida, the value of indirect cranial and cerebral markers was assessed by well-trained ultrasonographers in 13 different prenatal centres in accordance with the ISUOG (International Society of Ultrasound in Obstetrics and Gynecology) guidelines on fetal neurosonography. RESULTS: Open spina bifida was diagnosed in 98.9% of cases whereas 1.1% was closed spina bifida. Associated chromosomal abnormalities were found in 6.2%. The banana and lemon signs were evident in 97.1% and 88.6% of cases. Obliteration of the cisterna magna was seen in 96.7%. Cerebellar diameter, head circumference and biparietal diameter were below the 5th percentile in chromosomally normal fetuses in 72.5%, 69.7% and 52%, respectively. The width of the posterior horn of the lateral ventricle was above the 95th percentile in 57.7%. The secondary cranial and cerebral signs were dependent on fetal chromosome status and width of the posterior horn. Biparietal diameter was also dependent on the chromosome status with statistical significance p = 0.0068. Pregnancy was terminated in 89.6% of cases. CONCLUSION: In standard measuring planes, lemon sign, banana sign and an inability to image the cistern magna are very reliable indirect ultrasound markers of spina bifida. © 2014 John Wiley & Sons, Ltd.

Does Non-Placement of a Drain in Breast Surgery Increase the Rate of Complications and Revisions?

Purpose: Although surgical therapy for breast cancer has become less radical, intrasurgical placement of drains and the use of compression bandages is still standard practice. However, evidence for the clinical benefit of wound drains is controversial, and use of drains is associated with increased pain and longer hospital stays. This raises the question whether, given the latest surgical techniques, wound drainage is still medically necessary. Material and Method: A retrospective analysis was done of patients with breast cancer treated surgically between January 2009 and April 2012 in the Breast Centre Hohenlohe (n = 573). Complication rates and revision following surgery with and without placement of wound drains were compared for patients who had breast-conserving surgery (n = 425) and patients who underwent mastectomy (n = 148). Results: The baseline characteristics (age, number of resected lymph nodes, numbers of patients who had sentinel lymph node resection, tumour characteristics, receptor status and affected side) were comparable for the investigated patient groups. The overall rate of complications was 4 %. There was no significant difference with regard to complication rates after surgery with and without placement of wound drains between the group of patients with breast-conserving surgery and the group of patients with mastectomy (p = 0.68 and p = 0.54, respectively). Conclusion: Our data indicate that non-placement of a wound drain does not influence complication or revision rates after breast-conserving surgery or mastectomy.

Feto-amniotic shunting -- experience of six centres.

AIM: Foeto-amniotic shunting is an ultrasound-guided, therapeutic intervention for drainage of persistent intracavital fluid retention in severely affected foetuses with a high risk of mortality. In order to weigh up the comparatively high risk of intervention against the possible benefit, we evaluated the value of different indications, the complication rate and the time span of drains in situ. PATIENTS AND METHODS: We made a survey of all level III ultrasound centres of German-speaking countries from 1993 to 2001. Six level III centres returned the questionnaire: forty-seven foeto-amniotic shunting procedures were performed in 30 foetuses [megacystis in 18 foetuses (three of these with urinary ascites), hydrothorax in eight foetuses, hydronephrosis in two foetuses, cystic adenomatoid malformation of the lung in one foetus, ovarian cyst in one foetus]. RESULTS: The median gestational age at time of shunting was 23.5 (range 16 - 33) weeks, at time of delivery 35 (range 23 - 41) weeks. The median time span of drains in situ was 19 (range 0 - 170) days. Altogether 18 of 30 foetuses (60 %) had a benefit of foeto-amniotic shunting. CONCLUSION: The best possible selection of pregnancies which might profit from foeto-amniotic shunting is required. The decisive criteria are the underlying defect as well as the severity and progression of the disorder.

Prenatal diagnosis in a family with severe type I plasminogen deficiency, ligneous conjunctivitis and congenital hydrocephalus.

Severe type I plasminogen deficiency may cause severe ligneous conjunctivitis, a rare and unusual form of chronic pseudo-membranous conjunctivitis that usually starts in early infancy, but also pseudo-membranous lesions of other mucous membranes in the mouth, nasopharynx, trachea and female genital tract, and in rare cases congenital occlusive hydrocephalus. The index patient, the daughter of a consanguineous marriage, had suffered from severe ligneous conjunctivitis and had died from decompensated congenital hydrocephalus despite numerous shunt revisions. She was found to be homozygous for a non-sense mutation in exon 15 of the plasminogen gene (Trp597->Stop). In her next pregnancy, the mother asked for prenatal diagnosis of the plasminogen deficiency. Chorionic villus biopsy was performed at 12 weeks of gestation. DNA analysis of the plasminogen gene by PCR and single-strand conformation polymorphism (SSCP) revealed that the fetus exhibited an identical heterozygous band pattern as observed in the healthy mother. Therefore, the fetus was heterozygous for the Trp597->Stop mutation in plasminogen exon 15. In addition, the fetus was found to be male by cytogenetic analysis and by multiplex PCR analysis using two polymorphic X-chromosomal markers (DXS424, HPRT). These findings excluded the possibility of contamination by maternal DNA. It was concluded that the fetus was not at risk for ligneous conjunctivitis and its associated complications. After the birth of a healthy boy, plasminogen functional activity was shown to be 38 per cent. DNA analysis confirmed prenatal molecular genetic results.

Successful abdominal delivery in a woman with sonographic diagnosis of diffuse cavernous hemangioma of the uterus.

Diffuse hemangioma of the pregnant uterus is a serious lesion. We report the first case of a successful cesarean section at term following expectant management of pregnancy in a patient with presumed isolated diffuse cavernous hemangioma of the uterus and protein S deficiency. The sonographic diagnosis and clinical management of this condition is described. The presented successful pregnancy underlines that, under close surveillance, consideration should be given to a conservative approach to this sonographic finding during pregnancy, as even an abdominal delivery does not imply hysterectomy inevitably.

The shape of the endometrium evaluated with three-dimensional ultrasound: an additional predictor of extrauterine pregnancy.

The objective of this prospective follow-up study was to evaluate the potential utility of three-dimensional (3D) ultrasound to differentiate intrauterine from extrauterine gestations. Fifty-four pregnancies with a gestational age <10 weeks and with an intrauterine gestational sac <5 mm in diameter formed the study group. The configuration of the endometrium in the frontal plane of the uterus was correlated to eventual pregnancy outcome. After exclusion of three patients with a poor 3D-image quality the endometrial shape was asymmetrical with regard to the median longitudinal axis of the uterus in 84% of intrauterine pregnancies, whereas the endometrium showed a symmetry in the frontal plane in 90% of extrauterine pregnancies (P = 0.0000001). Intrauterine fluid accumulation may distort the uterine cavity, thus being responsible for false-positive as well as false-negative results. The evaluation of the endometrial shape in the frontal plane appears to be a useful additional means to distinguish intrauterine from extrauterine pregnancies, especially when a gestational sac is not clearly demonstrated with conventional ultrasound.

Fetal lung volumetry by three-dimensional ultrasound.

The aim of this study was to establish a method for determination of fetal lung volume by three-dimensional ultrasound. The thoraces of a total of 113 fetuses (singleton pregnancies, 11-41 weeks of gestation without any signs of malformation or oligohydramnios) were examined by three-dimensional ultrasound. Volumetric evaluation of each lung was performed in each of three perpendicular planes (six measurements in total). There were significant differences in all three measurements between the left and right lungs. Especially in the second and third trimesters, measurement of the frontal and the sagittal planes was sometimes prevented by poor imaging conditions. The scan volume was always too small for fetuses above 34 weeks. With these problems considered, nomograms of fetal lung volume for the left and the right lung were calculated. Lung volumes in the present study showed good correlation with published autopsy findings. Three-dimensional ultrasonographic volumetry is a useful method for determining fetal lung volume and may have a role to play in the detection of pulmonary hypoplasia.

Transvaginal ultrasonography of pelvic masses: evaluation of B-mode technique and Doppler ultrasonography.

OBJECTIVE: The purpose of this study was to evaluate pelvic masses by B-mode and Doppler ultrasonography for identification of ovarian malignancies. STUDY DESIGN: A previously described scoring system for pelvic masses was applied in 310 women, and the lesions were classified into four groups according to the ultrasonographic structure. Pulsatility index values of vessels within the tumor and the contralateral ovary and of both uterine arteries were determined. RESULTS: A total of 259 masses were benign and 51 were malignant. The scoring system and classification into morphologic groups revealed similar sensitivity, specificity, and positive and negative predictive values. Intratumoral and opposite ovarian blood flow and ipsilateral and contralateral uterine blood flow did not differ in benign and malignant masses except in cases of benign lesions in postmenopausal women. In malignant lesions a lower pulsatility index (0.94 +/- 0.4) was measured than in benign lesions (1.06 +/- 0.4, p < 0.05), although a remarkable overlap was found. CONCLUSION: The results suggest that further refinement of assessment of pelvic masses with Doppler ultrasonography is needed.

[Premature termination of pregnancy in the 2nd and 3rd trimester. Serial administration of 1 mg gemeprost vaginal suppositories versus intravenous sulproston]. / Vorzeitige Schwangerschaftsbeendigung im II. und III. Trimenon. Serielle Applikation von 1 mg Gemeprost-Vaginalsuppositorien versus Sulproston intravenös.

Comparison of 1 mg Gemeprost-Vaginal Suppositories Serial Application versus Sulproston i.v.: Three different regimens for the termination of second and third trimester pregnancies by the use of prostaglandins (PG) were compared in a retrospective analysis. In group A (n = 16) terminations were attempted by continuous i.v. Infusion of Sulproston 9 hours after administration of a 3 mg-PGE2-vaginal tablet overnight. In group B (n = 22), i.v. Sulproston was started 2 hours after priming with 1 mg Gemeprost-vaginal suppositories. The outcome of these two regimens was compared with that of repeated administration of 1 mg Gemeprost-vaginal suppositories at 6-hourly intervals (group C, n = 25). In each group. If uterine contractions failed to appear after one day, the treatment was discontinued for a sleep rest over night and then resumed. Genetic disorders or fetal malformations were the most frequent reasons for termination. Patients with intrauterine fetal demise, rupture of the membranes, preterm labour or a ripe cervix (Bishop Score > 3) were excluded. Median time intervals from induction to abortion were 33 hours in group A and 23 hours in each Group B and C. The rate of fetal expulsions within 12, 24 and 36 hours in groups B and C were similar. Women of parity > or = 1 showed significantly shorter intervals than nulliparae in groups A and C. Only one woman (in group A) failed to expel after induction, in four other cases (in groups A and B) complications (local thrombophlebitis, bronchospasm) were noted. The serial administration of 1 mg Gemeprost-vaginal suppositories at 5-hourly intervals showed fewer side effects and seems to be as efficient as sulproston i.v. after cervical ripening.

Experience with laparoscopic assistance in vaginal hysterectomy.

OBJECTIVE: To determine safety and usefulness of laparoscopy intended to convert an abdominal into a vaginal hysterectomy. STUDY DESIGN: Forty-seven consecutive hysterectomies are retrospectively analyzed in which laparoscopy was used to accomplish a vaginal instead of an abdominal procedure which would have been performed without endoscopic surgery. RESULTS: In four patients the operation had to be converted to laparotomy due to difficult access (n = 3) or heavy bleeding (n = 1). Operation time declined during the study period, thus highlighting the importance of experience with laparoscopic technics. Major complications such as injuries of adjacent organs or delayed haemorrhage requiring a second intervention were not encountered. CONCLUSIONS: Laparoscopy in hysterectomy seems to be a valuable method to avoid laparotomy. In the future, guidelines to determine the route of surgery are to be established which include those conditions in which laparoscopy in addition to vaginal hysterectomy implies a benefit for the patient.
