Pregnancy following rupture of the pregnant uterus

Abstract

Objectives: To review the cases of ruptured uterus at King Khalid University Hospital (KKUH) over the 11 years of the hospital's existence (1984–1994), to analyze the causative factors of uterine rupture with a view to its prevention, and to highlight the management approach in relation to maintaining the patients' future fertility. Methods: Case notes were reviewed for all patients with ruptured uterus at KKUH over a period of 11 years from January 1984 to December 1994. Relevant data relating to the clinical features, characteristics of labor, operative procedures, and maternal and perinatal outcome were assessed. Results: There were 11 cases of ruptured uterus, six of which occurred in patients with previous cesarean scars. Two patients were primigravidas, one of whom ruptured her uterus following a road traffic accident. In one patient with six previous preterm labors, rupture resulted from non-removal of cervical cerclage during labor. The rupture occurred in the fundus in one case, and in the lower segment in the remaining 10. Fetal heart abnormalities were observed in all cases in which the uterus ruptured during labor. Abdominal hysterectomy was performed in three cases, two of which were total and the third subtotal. The remaining eight patients had suture repair, all of whom became pregnant later and were delivered by cesarean section. Conclusion: Even though rupture of the uterus was a rare complication of pregnancy at KKUH, its occurrence should be suspected when there are sudden fetal heart abnormalities during labor, or unexplained postpartum shock. Suture repair should be considered whenever possible in order to preserve the patients' reproductive potential.
