Colcher-Sussman방법에 의한 X선골반계측에 관한 산과학적 연구 = A clinical study of X-ray Pelvimetry by colcher-sussman method

다국어 초록 (Multilingual Abstract)

The study was carried out retrospectively based on the clinical chart of 1746 obstetrical patients who received X-ray pelvimetry among a total of 14,000 patients admitted to the Dept. Of Ob. & Gy. from Sept. 1, 1968 to dec. 31, 1975 except 1969. The Colcher-Sussman technique was used to measure the various diameters of the pelvis while the biparietal diameter and weights of fetus were obtained postpartum. Even though pelvimetry has been widely used over the years and has been generally accepted as a clinical tool, this study was mainly concerned with relationships between pelvic diameters and fetal weight-size factors. 1. 1436 X-ray pelvimetry were taken in patients thought to have dystocia with a vertex presenting. In these patients, 53.6% had vaginal delivery, 4.2% had a mid forceps delivery and the remaining 42.1% received a cesarean section. 2. In the same group, when the A-P of the inlet was less than 10.0cm, the Cesarean section rate was 70.2% when between 10.0cm and 10.4cm the rate was 47.0% and above 10.5cm the rate was 30.5%. 3. Even better correlation is found in terms of type of delivery when the A-P of the inlet is related to the biparietal diameter of the infant. When the difference was between 1.0cm and 1.4cm the Cesarean section rate was 52.8% when the difference was between 1.5cm and 1.9cm the Cesarean section rate was 24.4% and above 2.0cm the rate was 14%. with the birth weight above 3500gm and the difference under 1.4cm the Cesarean section rate was around 58%. 4. When the transverse diameter of midpelvis was between 8.5-8.9cm the Cesarean section rate was 77.1% The mid-pelvic transverse diameter was much less accurate in predicting the method of delivery especially Cesarean section and mid-forceps delivery. 5. When used with nulliparous breech presentation the section rate was 46%. 6. In 1746 case who taken X-ray pelvimetey, 413 cases were spontaneous premature rupture of membrane, and the subsequent section rate was 40.4%.
