Conjoined Twins in a Triplet Pregnancy: A Case Report

Background. Conjoined twins are a rare complication of monozygotic twinning and are associated with high perinatal mortality.Case. Here we present a case of conjoined twins in a triplet pregnancy diagnosed at 13 of weeks gestation. With the aid of 3D ultrasound and MRI images, the parents were counseled regarding the management options, including continuation of pregnancy, termination of pregnancy, or selective fetocide. They chose selective fetocide of the conjoined twins and went on to deliver the remaining triplet at term.Conclusion. This case represents to our knowledge the only MRI images of conjoined twins in a triplet pregnancy and demonstrates how 3D imaging can be used to better counsel patients about management options.

Ultrasonographic Examination

Objective. Conjoined twin is a rarely seen congenital anomaly together with severe mortality and morbidity. The more common types of conjoined twins include the thoracopagus type, where the fusion is anterior, at the chest, and involves the heart. We are reporting one case of conjoined thoracopagus twins diagnosed by ultrasonography at 11 weeks. Case Report. In a multigravid pregnant woman who has been admitted to our clinic with a diagnosis of conjoined twins, thoracopagus, by ultrasonography at an 11-week gestation, termination of the pregnancy was performed. Conclusion. Making an early diagnosis with ultrasonographic examination gives the parents a chance to elect pregnancy termination.

Surgical Separation

Conjoined twins are a very rare complication of monochorionic monoamniotic pregnancies, associated with severe mortality and morbidity. Ultrasonography has made early diagnosis of conjoined twins possible, allowing prompt management and counselling of parents. The diagnosis should be suspected when monozygotic fetuses are shown to consistently hold the same fixed position relative to each other. The location and extent of fusion between the twins determine the potential for surgical separation and postnatal survival. The authors report a case of conjoined thoraco-omphalopagus twins, diagnosed by ultrasonography at 10 weeks of gestation. Due to high complexity of fetal fusion, termination of pregnancy was performed upon patient´s request.

Present Case Study

In the present case study we are reporting a case of thoracoomphalopagus conjoined twins. A 24 years old gravida two para 0+1 carrying thoracoomphalopagus conjoined twins was diagnosed by ultrasonography at early second trimester with single placenta attached posteriorly and low lying. The mortality and morbidity of conjoined twins are high so making the early diagnosis with ultrasonographic examination provides the parents a chance to elect for pregnancy termination.

Abstract Background Conjoined twins are a rare and serious complication of monochorionic twins. The total incidence is 1.5 per 100,000 births, and about 50% are liveborn. Prenatal screening and diagnosis of conjoined twins is usually performed by ultrasonography. Magnetic resonance imaging can be used to assist in the diagnosis if necessary. Conjoined twins in dichorionic diamniotic triplet pregnancy are extremely rare. Case presentation We reported three cases of dichorionic diamniotic triplet pregnancy with conjoined twins. Due to the poor prognosis of conjoined twins evaluated by multidisciplinary teams, selective termination of conjoined twins was performed in three cases. In case 1, selective reduction of the conjoined twins was performed at 16 gestational weeks, and a healthy female baby weighing 3270 g was delivered at 37 weeks. In case 2, the conjoined twins were selectively terminated at 17 weeks of gestation, and a healthy female baby weighing 2760 g was delivered at 37 weeks and 4 days. In case 3, the conjoined twins were selectively terminated at 15 weeks and 2 days, and a healthy female baby weighing 2450 g was delivered at 33 weeks and 6 days. The babies of all three cases were followed up and are in good health. Conclusion(s) Surgical separation is the only treatment for conjoined twins after birth. Early determination of chorionicity and antenatal diagnosis of conjoined twins in triplet gestations are critical for individualized management options and the prognosis of normal triplets. Expecting parents should be extensively counseled by multidisciplinary teams. If there are limitations in successful separation after birth, early selective termination of the conjoined twins by intrathoracic injection of potassium chloride may be a procedure in dichorionic diamniotic triplet pregnancy to improve perinatal outcomes of the normal triplet.
