Surgical correction of cervical incompetence

Results obtained with a modified surgical cerclage technique in 80 patients suffering from isthmic cervical incompetence are analyzed. The operation was performed once in 58 patients and twice in 22, giving a total of 102 pregnancies treated. The technique is described in detail, emphasizing its advantages. In 73 pregnancies (71.5%) the outcome was satisfactory (the newborn babies survived) despite the fact that in 66 instances (65%) cervical modifications were present at the time of the operation.
