We wish to report that 1 of our patients a 30-year-old nulliparous married woman was safely delivered by cesarean section on July 25 1978 of a normal healthy infant girl weighing 2700 g. The patient had been referred to 1 of us (P.C.S.) in 1976 with a history of 9 years infertility tubal occlusions and unsuccessful salpingostomies done in 1970 with excision of the ampullae of both oviducts followed by persistent tubal blockages. Laparoscopy in February 1977 revealed grossly distorted tubal remnants with occlusion and peritubal and ovarian adhesions. Laparotomy in August 1977 was done with excision of the remains of both tubes adhesolysis and suspension of the ovaries in good position for oocyte recovery. Pregnancy was established after laparoscopic recovery of an oocyte on November 10 1977 in-vitro fertilization and normal cleavage in culture media and the reimplantation of the 8-cell embryo into the uterus 2 1/2 days later. Amiocentesis at 16 weeks pregnancy revealed normal alpha-fetoprotein levels with no chromosome abnormalities in a 46 XX fetus. On the day of delivery the mother was 38 weeks and 5 days by dates from her last menstrual period and she had preeclamptic toxemia. Blood-pressure was fluctuating around 140/95 edema involved both legs up to knee level together with the abdomen back hands and face; the blood-uric-acid was 390 mcmol/l and albumin 0.5 g/l of urine. Ultrasonic scanning and radiographic appearances showed that the fetus had grown slowly for several weeks from week 30. Blood-estriols and human placental lactogen levels also dropped below the normal levels during this period. However the fetus grew considerably during the last 10 days before delivery while placental function improved greatly. On the day of delivery the biparietal diameter had reached 9.6 cm and 5 ml of amniotic fluid was safely removed under sonic control. The lecithin:sphingomyelin ratio was 3.9:1 indicative of maturity and a low risk of the respiratory-distress syndrome. We hope to publish further medical and scientific details in your columns at a later date. (full text)
