Abstract: Heterokaryotypic monozygotic twins are rare. We report a set of monochorionic diamniotic twins complicated with lethal malformations and hydrops in one fetus at menstrual age of 16 weeks’. Sonographic appearances and genetic am-niocentesis result suggested for 45,X and 46,XY heterokaryotypic twins. Coexisting polyhydramnios found in the sac of severely malformed 45,X fetus threatened miscarriage and premature delivery. To salvage the phenotypically normal male fetus, the hydropic 45,X co-twin was selectively terminated by occlusion of its umbilical cord with bipolar dia-thermy. Complete cessation of funicular flow was achieved, resulting in normalization of total amniotic fluid volume. A healthy 2200-gram baby boy was born at 38 weeks’. His neurodevelopment was intact at 2 years of age. His physical examination was significant for slight growth delay (15 percentiles), with 6% of 45,X mosaicism found in his peripheral blood. Owing to the rarity of the cases, limited data is available regarding an optimal treatment for heterokaryotypic monochorionic twins with discordant lethal malformation. Intrauterine intervention may be offered should demise or permanent disabilities are imminent to the apparently normal fetus.
Acardiac Parabiotic Twin: A Case Report

Iranian Journal of Radiology , 2007,
Abstract: The incidence of anomalies is high in multiple gestations especially in monochorionic twins. This paper reported a case of an acardiac parabiotic twin, a rare deformed fetus which occurs typically in monochorionic twin gestations. It is a severely deformed fetus without heart and limited development of the upper half of the body.
Epigastric Heteropagus Twin

APSP Journal of Case Reports , 2011,
Abstract: Parasitic twining is a rare type of monozygotic monochorionic monoamniotic asymmetrical conjoined twin. We report a case of epigastric heteropagus twin. An ultrasound scan showed a defect of 1.5 cm in the epigastrium. CT showed soft tissue lobulated mass with fat and air components coming out of the epigastric defect. At operation rudimentary alimentary canal with no viscera, was found in the parasite. The parasite was easily separated from the host.
Undiagnosed xiphopagus twins: a perinatal malady

Clinics and Practice , 2012, DOI: 10.4081/cp.2012.e23
Abstract: Conjoined twins are a very rare entity. It is associated with poor survival rate in the presence of vital organ sharing. The entity can be diagnosed as early as the first trimester. A conjoined twin diagnosed late in labor is a malady with high perinatal mortality and maternal morbidity. We present one such case of xiphopagus twins. The management of a case diagnosed late in labor can be very challenging. Such obstetric challenges can be avoided by a meticulous early scan with a high index of suspicion, especially in the absence of separating membrane while scanning multiple pregnancies.

Abstract: The twin-to-twin transfusion syndrome (TTTS) is a severe complication of monochorionic twin pregnancies, caused by inter-twin transfusion of blood from one fetus (the donor) towards the other fetus (the recipient) through placental anastomoses. Twin to twin transfusion complicates about 15-30% of monochorionic twin gestations and is responsible for 17% of the perinatal mortality in multiple pregnancies. The donor twin become anemic, hypovolemic and looses amniotic fluid where as the recipient becomes plethoric, hypervolemic and gains excess amniotic fluid .Both fetuses are at risk due to adverse hemodynamic changes following abnormal vascular communication . Severe TTTS has a 60-100% fetal or neonatal mortality rate. Mild-to-moderate TTTS is frequently associated with premature delivery. Fetal demise of one twin is associated with neurologic sequelae in 25% of surviving twins. We report a rare case of twin to twin transfusion syndrome in a primigravida ,who fulfilled the diagnostic criterias of the condition .Patient had miscarriage at 27 weeks of gestation due to severe uteroplacental insufficiency.Aetio-pathology ,hemodynamic alterations ,diagnostic modalities ,management options and prognosis is discussed in the report.
Fetus in Fetu (Pre-surgical dilemma: Review of literature and a case report)
Om Prakash Sharma, Senthil Shanmugam
Asian Journal of Medical Sciences , 2011, DOI: 10.3126/ajms.v2i1.3208
Abstract: Fetus in fetu is an extremely rare developmental anomaly, due to disorganised embryogenesis in a diamniotic monochorionic pregnancy. Approximately 87 reports have been documented in the literature to date. We describe such an entity in two months old boy, who presented with abdominal distension and features of obstruction. Plain X ray abdomen and CT scan helped in correct pre operative diagnosis. The literature on this rare entity is reviewed, and the diagnosis and pathogenesis of the disease are discussed.

Abstract: objective: to report our initial institutional experience with fetoscopic laser photocoagulation of placental anastomoses in severe twin-twin transfusion syndrome using a 1.0 mm endoscope. methods: between july 2006 and june 2008, 19 monochorionic diamniotic twin pregnancies complicated by severe ttts (quintero stages iii and iv) underwent fetoscopic laser therapy. perinatal data were prospectively collected and compared according to the quintero stages. results: nine patients were classified as stage iii and ten as stage iv. the mean gestational ages at diagnosis and procedure were 20 (range: 17-25) and 22.0 (range: 19.0-26.0) weeks, respectively, with no statistical difference between the two groups. preterm premature rupture of the membranes occurred in two cases (10.5%), and spontaneous preterm delivery in eight (42.1%). overall mean gestational age at delivery was 32.1 (range: 26.0-38.0) weeks. prematurity was more severe in stage iv patients (p<0.01). among all cases, the overall survival rate was 52.6%, and the percentages of pregnancies with survival of both babies and at least one twin were 26.3% and 78.9%, respectively. in the case of stage iii patients, the overall survival rate was 61.1%. of the stage iii pregnancies, 33.3% resulted in both babies surviving, and 88.9% of these pregnancies resulted in at least one surviving twin. for stage iv, as the corresponding statistics were 45.0%, 20.0% and 70.0% respectively. conclusions: our initial institutional experience with 1.0 mm fetoscopic laser therapy for severe ttts showed results similar to those reported in the literature for larger endoscopes.

Abstract: Our objective was to evaluate which demographic factors or assisted reproductive technologies were associated with IVF triplet gestations where one of the embryos split, resulting in a dichorionic triplet gestation. This was a case-control study of dichorionic versus trichorionic triplet gestations that underwent assisted reproductive technology over the last 5 years at our fertility center. There were 53 cases of dichorionic triamniotic triplet gestations compared to 119 trichorionic triplet controls. There were no significant demographic differences between the cases and controls. 51/53 dichorionic triplets and 86/119 trichorionic triplets were conceived through IVF, the remaining utilized intrauterine insemination. ICSI was performed in virtually all patients that underwent IVF. Of the potential risk factors studied, hatching was used in 70.6% of dichorionic compared to 89.5% of trichorionic IVF triplets (p = 0.005); embryo transfer was performed on Day 5 or 6 compared to Day 3 in 88.0% dichorionic vs 71.8% trichorionic (p = 0.028). Frozen sperm was utilized more frequently with dichorionic than with trichorionic triplets, 26.0% vs 10.9% (p < 0.011). Only 4 (7.5%) of the IVF cases underwent pre-implantation genetics. Certain assisted reproductive technologies appear to be associated with embryo splitting and a dichorionic triplet gestation. More research is needed in this area to further elucidate these findings.
