We reviewed all cases of uterine perforations which occurred at or were referred to the Boston Hospital for Women, Lying-In Division, over the 2 year period from mid-1975 to mid-1977. There were 25 uterine perforations; twenty patients were pregnant and five were not. In the pregnant patients, 16 perforations involved the cervix or the lower uterine segment, whereas only four were located in the uterine fundus; in the nonpregnant patients, all five were fundal perforations. In the pregnant patients, 12 required laparotomy, eight had serious lacerations of the uterine artery, and three had hysterectomy while none of the nonpregnant patients had lacerations or required subsequent procedures. Thus, there is a significant anatomic difference between those perforations which occurred in the pregnant patients and in the nonpregnant patients, the manner in which they presented clinically, and the need for intervention via laparotomy, subsequent morbidity, and outcome as reflected in future reproductive capability. Perforation at or near the cervix may be more common than previously assumed. Furthermore, two distinct clinical entities of cervical perforation exist in pregnant patients as based on the anatomic location of the defect. The anatomy of cervical perforations, their recognition, and their management are discussed. © 1979.
