Background: Stillbirth has a complex pathophysiology, hence the difficulty in arriving at a specific cause. Objectives The study aimed to identify the probable causes of stillbirth in a tertiary hospital based on gross examination of the placenta and the fetus, as well as, to identify the demographic profile of the stillbirths.

Background: The contemporary obstetrician is increasingly put to the test by rising numbers of pregnancies with morbidly adherent placenta. This study illustrates our experience with prophylactic bilateral internal iliac artery occlusion as part of its management. Methods: Between January 2011 to January 2014, 13 consecutive patients received the intervention prior to scheduled caesarean delivery for placenta accreta. All cases were diagnosed by ultrasonography, color Doppler imaging and supplemented with MRI where necessary. The Wanda balloonTM catheter (Boston Scientific, Natick, MA, U.S.A) were placed in the proximal segment of the internal iliac arteries preceding surgery. This was followed by a midline laparotomy and classical caesarean section, avoiding the placenta. Both internal iliac balloons were inflated just before the delivery of fetus and deflated once haemostasis was secured. Primary outcomes measured were perioperative blood loss, blood transfusion requirement and the need for ICU admission. Results: The mean and median intraoperative blood loss were 1076mls±707 and 800mls (300-2500) respectively while mean perioperative blood loss was 1261mls±946. Just over half of the patients in our series required blood and/or blood products transfusion. Two patients (15.4%) required ICU admission. Conclusion: Our study suggests that preoperative prophylactic balloon occlusion of bilateral internal iliac arteries reduces both blood loss and transfusion requirement in patients with placenta accreta, scheduled to undergo elective caesarean hysterectomy. It is an adjunct to be considered in the management of a modern day obstetric problem, although the authors are cautious about generalizing its benefit without larger, randomized trials.
Placenta Accreta

The study described the use of human placenta as a dialyzing medium. This is a preliminary reportThe subject was a dog legated to produced uremia. A freshly delivered placenta was obtained. The two arteries and the vein of the umbilical cord were cannulated separately using glass cannules. The femoral vessels of the dog were exposed and cannulated on both sides. The cannulated vessels of the dog and the placent were connected to establish a closed circulation, such that the dogs blood flowed from the femoral arteries to the umbilical arteries through the placenta to the umbilical vein, then back to the femoral vein of the dog and its general circulationThe establishment of circulation through the placenta was satisfactory. The NPN and creatinine levels were determined and recorded.(Author)
