RESUMEN
OBJECTIVE: To determine the efficacy of ultrasonogram in the detection of cornual pregnancy and the factors that might be affected on early diagnosis. METHOD: We studied 26 cases which were diagnosed as a cornual pregnancy from Jan, 1, 2000 to Dec, 31, 2004 at department of Obstetrics and Gynecology, St. Vincent's Hospital, the Catholic University of Korea. We compared two groups about clinical characteristics and outcomes. One group (A group) was diagnosed as cornual pregnancy before beginning of treatment, another group (B group) was not diagnosed as cornual pregnancy until operation. RESULTS: A group was 8 cases (30.8%) and B group was 18 cases (69.2%). There were no significant differences in age (33.0+/-6.21 years : 31.0+/-5.82 years), duration of amenorrhea (7.32+/-1.07 weeks : 8.90+/-5.44 weeks), previous cesarian section history (25.0% : 27.8%), present myoma (12.5% : 11.1%) and abdominal pain (50% : 77.78%), vaginal bleeding (50% : 55.6%), shock (0% : 27.8%) between two groups. There were significant differences in parity (1.63+/-0.74 : 1.0+/-0.77, p=0.032), number of abortions (2.25+/-1.16 : 1.11+/-1.18, p=0.016), previous history of ectopic pregnancy (37.5% : 0%, p=0.022). Of the method of treatments, only cornual resection (50% : 94.4%) showed significant differences between two groups. CONCLUSION: 30.8% of cornual pregnancy was early diagnosed by ultrasonogram. The important early detective factors for cornual pregnancy might be parity, previous ectopic pregnancy history and abortion history. Therefore if the patient has the previous ectopic pregnancy and abortion history, she can visit early to the hospital and the doctors do pay attention to the possibility of cornual pregnancy.
