Successful Vaginal Delivery in Locked Twins: A Case Report

Abstract

Locked twins is a rare and dangerous multiple pregnancy and generally occurs in about 1 in every 1000 twin births. A 23‑year‑old female with gravida 1, para 0 pregnancy was admitted. The head of the first fetus was locked to the chin of the second fetus (alive) at the top of the symphysis pubis. The uterus was relaxed with isoflurane. The legs and the back of the baby were extended to the symphysis pubis. The head of the second baby was gently positioned to the posterior walls of uterine cavity on the upper side of it. So, the locked head of the first baby was released and both fetuses were delivered vaginally. The second baby was in good condition. By recognizing the probable cases, radiological diagnosis, and punctual cesarean delivery, it is possible to avoid the fetal morbidity and mortality in locked twins.
