Fertility and pregnancy outcomes following hypogastric artery ligation for severe post-partum haemorrhage

BACKGROUND: Hypogastric artery ligation is a therapeutic option for severe post-partum haemorrhage. Little is known about the outcomes of subsequent fertility and pregnancy. We studied these parameters in women who required hypogastric artery ligation for severe post-partum haemorrhage in our institution over a 13-year period. METHODS: All patients who required hypogastric artery ligation for severe intractable post-partum haemorrhage from January, 1989 to April, 2001 were included. Data were retrieved from medical files and telephone interviews. RESULTS: A total of 68 patients required hypogastric artery ligation during the study period. Seventeen patients had 21 pregnancies with 13 term deliveries, two ectopic pregnancies, three miscarriages, and three abortions. Twenty-eight patients did not want a new pregnancy and one patient refused the interview. Twenty-three (34%) patients were lost to follow up. None of the patients suffered subsequent infertility and pregnancy was achieved in <12 months once planned. Pregnancy outcomes were normal. Fifty-four percent had vaginal deliveries. Three patients suffered a threatened post-partum haemorrhage that was easily treated medically. CONCLUSIONS: This is the largest reported series of pregnancies following hypogastric artery ligation. Hypogastric artery ligation for post-partum bleeding >1 l appears to be a safe procedure that does not impair subsequent fertility and pregnancy outcomes.     

Prenatal diagnosis of a complete mole coexisting with a dichorionic twin pregnancy: case report

A complete mole coexisting with dichorionic twins was diagnosed by the combined use of sonography and chorionic villus sampling at 10 weeks gestation. The pregnancy resulted in the death of one fetus at 31 weeks from presumed feto-maternal haemorrhage, while the other fetus survived in good condition. A summary of the available literature, combined with this report, reveals a total of seven pregnancies with twins and a coexistent complete mole. Only two out of 14 fetuses survived. Maternal complications included one case of pre-eclampsia and one persistent trophoblastic tumour. Accurate diagnosis of complete mole is possible by genetic analysis of chorionic villi obtained with standard transabdominal sampling. Twins with a coexistent complete mole will usually undergo miscarriage. However, fetal survival is possible and the maternal risks seem limited. A concomitance between gestational trophoblastic disease and the occurrence of feto-maternal haemorrhage is observed.     

Influence of maternal infections with viral agents or Toxoplasma gondii during pregnancy on fetal IgE production

The importance of maternal infections with Toxoplasma gondii , cytomegalovirus (CMV), Parvovirus B19, respiratory syncytial virus (RSV), and influenza A and B on fetal IgE synthesis was studied in 153 pregnant women. No case of specific IgM activity or viral DNA in cord blood, indicating a congenital infection, was found. From gestational week 15 to delivery, maternal IgG-Ab seroconversion to Parvovirus B19, RSV, influenza A, or influenza B occurred in 47 women. At delivery, serologic signs of past infection with T. gondii were observed in 29 (19%) women, and the corresponding figure for CMV was 117 (77%). The number of women with positive IgG seroconversion during pregnancy or positive IgG-Ab activity toward the studied infectious agents at delivery did not differ significantly among infants with an increased (≥1.3 kU/1; n =51) or with an undetectable (<0.1 kU/l; n =102) cord-blood IgE level. These results show that genetic and other environmental factors probably have a greater influence on fetal IgE synthesis than do maternal infections during pregnancy.     

Alternative Treatment to Lymphocyte Immunization for Treatment of Recurrent Spontaneous Abortion: Immunotherapy With Intravenous Immunoglobulin for Prevention of Recurrent Pregnancy Loss: European Experience

PROBLEM: Due to its strong “immunomodulating” effect in several well established disorders, high-dose intravenous immunoglobulins (IVIG) has been proposed as an alternative for immunotherapy with allogeneic leucocytes in patients with unexplained recurrent spontaneous abortion. This paper is intended to provide an overview on the European experience in this field. METHOD: Five European pilot studies with a total of 172 patients as well as one controlled double-blind multicenter study including 64 patients were considered. In the latter, 5% human albumin was used as placebo. RESULTS: Success rates of the pilot studies varied from 68 to 87%. In the German controlled study, a significant specific effect of IVIG could not be verified. However, success rates for both IVIG and albumin were in the same range as for allogeneic leucocytes. CONCLUSION: At present, it is not sufficiently proven that IVIG is an appropriate tool for immunotherapy of recurrent spontaneous abortions. It is suggested that success rates of both IVIG and albumin are due to a placebo effect. However, we cannot exclude that albumin itself provides immunomodulating capacity.     

Pregnancy outcome after blastocyst transfer as compared to early cleavage stage embryo transfer

BACKGROUND: Retrospective cohort study to evaluate differences in outcome when embryo transfer was performed either on day 2-3 (cleavage stage, CS-group) or on day 4-5 (blastocyst stage, BS-group). METHODS: A total of 1259 consecutive cycles yielding 500 live born babies performed at a single centre in Bregenz, Austria, were included. Main outcome measures were implantation and (multiple) pregnancy rates and neonatal outcome including birth defects. RESULTS: Total Pregnancy rate was 44% vs 28% (P < 0.001) and the total 'take home baby rate' was 37% vs 22% in the BS-group and the CS-group, respectively. Rate of multiple gestations (34% vs 17%, P = 0.001) was significantly higher among the BS-group, resulting in a higher rate of preterm deliveries < 36 weeks (26% vs 17%, P = 0.045). Female factor causing infertility (40% vs 21%, P < 0.001) was significantly higher among the BS-group. For the CS-group, rate of singleton pregnancies (83% vs 66%, P = 0.001) and idiopathic cause of infertility (34% vs 22%, P = 0.012) were significantly higher. No statistically significant differences were found in sex, Caesarean section rate, Apgar score and umbilical artery pH-values, total mean birth weight, admission rate to intensive care unit, days of hospitalization and number of minor and major birth defects. CONCLUSIONS: Our data suggest that blastocyst transfer may lead to a higher pregnancy rate with an overall better take-home baby rate (THBR) at the cost of higher rates of multiples and preterm deliveries.     

Operative morbidity and reproductive outcome in secondary myomectomy: a prospective cohort study

BACKGROUND: This prospective study was designed to evaluate the operative morbidity and reproductive outcome in patients who had secondary myomectomy for recurrent symptomatic uterine fibroids. METHODS: A total of 58 women were subjected to a secondary myomectomy via the abdominal route. The operative morbidity such as blood loss, presence of adhesions and febrile index were estimated and the pregnancy outcome over a 2-4 year period of follow-up. RESULTS: The mean age and standard deviation (+/- SD) of the women was 35 (+/- 2.4) years. Nineteen patients (33%) had a postoperative temperature vertical line 100 degrees F and the estimated blood loss ranged from 159-2500 ml (median 700 ml). Seven patients (12%) required blood transfusion and one had a hysterectomy due to haemorrhage. Nine women (15.5%) became pregnant but only five (56%) had live births. Those with successful pregnancies tended to be younger with a mean age of 31.8 (+/- 2.6) years versus 35 (+/- 1.8) years, (P = 0.08, non-significant) and had fewer uterine leiomyomata; median with range values, 2 (1-6) versus 7 (6-15). The variables which best predicted the postoperative likelihood of pregnancy were; age, presence of tubal adhesions and the number of uterine fibroids. CONCLUSION: This prospective study showed a high operative morbidity and a poor fertility outcome after a repeat myomectomy. The factors affecting successful outcome in a logistic regression model were age, tubal adhesions and number of uterine fibroids.     

Functional and morphologic studies of the adrenal cortex and kidney in ovine toxaemia of pregnancy

Functional and morphologic studies of the adrenal cortex and kidney have been carried out in pregnant sheep with spontaneous or dietary restriction-induced ovine toxaemia. It was found that proteinuria was an inconstant feature and no animal showed glomerular lesions analogous to those found in human preeclampsia; thus ovine toxaemia cannot be regarded as a precise experimental model for human toxaemia of pregnancy. The elevation of blood cortisol levels and the morphologic appearance of the adrenal zona fasciculata found in such animals suggest an adrenal response comparable to that caused by adrenocorticotrophic hormone. In addition, animals with severe disease showed evidence of stimulation of the renin-angiotensin-aldosterone system as reflected by elevated blood renin and aldosterone concentrations and raised renal juxtaglomerular indices. Ultrastructural changes in the adrenal zona glomerulosa and renal juxtaglomerular myoepithelioid cells in toxaemic animals resembled those described in non-pregnant sodium-depleted sheep. The finding of juxtaglomerular peripolar cell mitoses and granule exocytosis, the latter only being previously observed in sodium depleted sheep, together with the ultrastructural changes in the adrenal zona glomerulosa and juxtaglomerular myoepithelioid cells, suggest that sodium depletion may play a role in this disease.     

Fetoscopic photography

Fetoscopic visualization may be used for the prenatal diagnosis of external structural malformations of the fetus. Objective documentation of these fetoscopic findings would be desirable. The photographic equipment and techniques required for fetoscopic photography have been investigated, and the results of these investigations with standard fetoscopic instruments in current clinical usage are described. The factors evaluated include the light source, camera equipment, camera settings and film.     

The acrosome index, radical buffer capacity and number of isolated progressively motile spermatozoa predict IVF results

BACKGROUND: The accuracy by which a number of newly described semen variables can predict either total fertilization failure (TFF) or pregnancy outcome in IVF, has not previously been investigated. The study aim was, therefore, to determine prospectively the predictive value of these variables. METHODS: The semen variables investigated were the post-wash total progressively motile sperm cell count (TPMC(post-wash)), the acrosome index (AI), 'cytoplasmic residues' and normal sperm morphology, evaluated according to the strict criteria ('strict criteria'), as well as the fast and slow total radical trapping antioxidant potential ('fast TRAP' and 'slow TRAP' respectively). RESULTS: The study group (n = 87) showed a mean (+/- SD) number of 10.2 +/- SD retrieved oocytes, 12.6% TFF, a mean fertilization rate of 59.7% and a pregnancy rate of 19.5% (17/87). TFF was significantly predicted by TPMC(post-wash), 'strict criteria', AI and 'cytoplasmic residues' (all P < 0.05). The outcome after embryo transfer was significantly predicted by AI and 'fast TRAP'. Semen samples with an AI <5% and a 'fast TRAP' <1.14 mmol/l in particular did not result in any pregnancies after IVF-embryo transfer. CONCLUSIONS: Of all the measured and calculated semen variables, TPMC(post-wash) was the best predictor of TFF, whilst AI and 'fast TRAP' were the best predictors of pregnancy after IVF.
