INTRODUCTIONPlacenta praevia is characterized by the abnormal placenta overlying the endocervical os, and it is known as one of the most feared adverse maternal and fetalneonatal complications in obstetrics.1 Women with placenta praevia are at an increased risk of second trimester vaginal bleeding.2 Placenta praevia is a source of drastic pregnancy, fetal and neonatal complications, e.g. peripartum hysterectomy, blood transfusion, postpartum hemorrhage, and placenta accreta for the mother, prematurity and intrauterine growth restriction for the fetus and increase in neonatal mortality rates in singleton pregnancies. 3Pathophysiology of placenta praevia is uncertain.Moreover, there appears to be an association between endometrial damage and uterine scarring and subsequent placenta praevia. We have conducted this study to find out the incidence of placenta praevia in Najran University Hospital. 4 METHODSThis study is a cross-sectional descriptive, one-year retrospective and one-year prospective study, carried out from April 2014 to April 2016. All pregnant women attended the antenatal care clinic in Najran University Hospital during the study period, were included. The data was collected in a designed questionnaire after informed consent from all patients in the prospective period.The patient's records in the retrospective period were the source of data. Abdominal Ultrasound scanning was ABSTRACT Background: Placenta praevia is a source of drastic pregnancy, fetal and neonatal complications. There was variable incidence in the literature in different parts of the world and within the same country regions. We carried out this study to find the impact in our area and the possible risk factors for this serious obstetric problem. Methods: This study is a cross-sectional descriptive, one-year retrospective one-year prospective study, carried out from April 2014 to April 2016. All pregnant women attended the antenatal care clinic in Najran University Hospital during the study period, were included. Results: The incidence of placenta praevia was found to be 2.7%. AMONG the study group, the most affected age group was between 20-29 years. Previous placenta praevia and previous caesarean section were the significant risk factors P=0.00 and 0,017 repectively. Conclusions:The incidence of placenta praevia in Najran KSA in this study was high, compared to other regions in Saudi Arabia and the majority of the international figures. Caesarean section and previous placenta praevia were the significant risk factors for placenta praevia in this study.

Intestinal obstruction during pregnancy is very rare. The mechanical intestinal obstruction was mostly due to adhesion from previous surgery.  Pregnancy may mask the symptoms of intestinal obstruction, and virgin abdomen adds to the ambiguity of the diagnosis. The mortality and morbidity increased for the mother and the fetus in the presence of bowel gangrene. We present a case of intestinal obstruction at mid-term pregnancy with extensive small bowel gangrene which necessitates right hemicolectomy and ends with a good outcome for the mother and fetus.
