Emergency peripartum hysterectomy in a tertiary Istanbul hospital.

OBJECTIVE: To evaluate the incidence, risk factors, indications, outcomes and complications of emergency peripartum hysterectomy performed after cesarean and vaginal deliveries. METHOD(S): We analyzed retrospectively 28 cases of emergency peripartum hysterectomy operations performed between February 2001 and February 2007 at the Istanbul Goztepe Training and Research Hospital, which is a teaching hospital operating under the Turkish Ministry of Health. The indications, risk factors and the associated complications were compared with control groups. Statistical analysis was performed using the STATA version 7.0 statistical package (Stata Corporation, College Station, TX, USA). RESULT(S): The overall incidence of emergency peripartum hysterectomy at our hospital is 0,37 in 1,000 deliveries. Abnormal placental adherence and uterine atony comprised 85% of the indications for peripartum hysterectomy. Postoperative maternal morbidity occurred in 15 cases (54%). Most had a febrile morbidity and depression. Seven patients underwent postpartum histerectomy due to consumptive coagulopathy. There was one maternal mortality (4%) and five perinatal mortalities (18%). The maternal death was due to consumptive coagulopathy after placental abruption. All patients had to receive blood transfusions. The median number of postoperative hospitalization days was 7. CONCLUSION(S): Peripartum hysterectomy is still a dramatic life-saving operation with high risks. The most common reason for abnormal placental adherence is previous uterine procedures.

The relation of increased uterine artery blood flow resistance and impaired trophoblast invasion in pre-eclamptic pregnancies.

OBJECTIVE: To assess the association between histopathologically confirmed vascular abnormalities developed during pre-eclampsia and abnormal arterial blood flows recorded during Doppler sonographies. MATERIALS AND METHODS: From pregnant women who attended our clinic between 01/03/2002 and 01/07/2002, a detailed medical history was obtained and routine biochemical blood tests, fetal ultrasonography and UA Doppler scans were performed. In addition, from pre-eclamptic and normal pregnant women who underwent cesarean sections, placental bed biopsies were taken. Thirty two pre-eclamptic [12 mild, 20 severe cases according to American College of Obstetricians and Gynecologists (ACOG) criteria] cases and as a control group 20 normal pregnancies were included in the study. In our study trophoblast invasion into decidual spiral arteries was observed in 75% of mild (9/12), and 55% of severe (11/20) pre-eclampsias. In the control group all the cases demonstrated trophoblast invasion in decidual spiral arteries. Trophoblast invasion in myometrial spiral arteries was noted in 50% (6/12) of mild and 25% (5/20) of severe pre-eclamptic pregnancies. It was seen in 16 cases out of 20 (80%) pregnancies. In the control group, decidual spiral artery invasion manifests significant differences (P<0.01) among groups studied. Invasion in decidual spiral arteries was seen in all normal pregnancies of the control group. There is not any significant difference between mild and severely pre-eclamptic groups (P>0.05). CONCLUSION: Doppler ultrasonography is not only a non-invasive method for evaluating fetal status in pre-eclamptic pregnancies, but it also correlates with partial trophoblastic invasion in spiral arteries, which contributes to the pathophysiologic mechanisms involved in pre-eclampsia.
