Epigastric heteropagus is a very rare form of conjoined twins. It results from an ischemic atrophy of the body structure of the monozygotic conjoined twins at an early gestational age. Diagnosis is made by prenatal echography which must look for congenital heart disease associated in 28% of epigastric heteropagus. Cesarean section is indicated to prevent for mechanical dystocia. The autosite component of epigastric heteropagus can successfully be treated with early minor surgery. Autosite twin survival is good. Discussion with the family is important to avoid needless terminations. We report a rare prenatal diagnosis of epigastric parasitic twinning in which the parasite had pelvis with lower limbs. At birth, the autosite had omphalocele containing only bowel loops from the parasite.
上腹部寄生胎是连体双胞胎中一种非常罕见的形式。它是由单卵连体双胞胎在孕早期身体结构的缺血性萎缩导致的。通过产前超声检查进行诊断,这种检查必须查找28%的上腹部寄生胎所伴发的先天性心脏病。剖宫产术适用于预防机械性难产。上腹部寄生胎的自体部分可通过早期小型手术成功治疗。自体双胞胎的存活率良好。与家属进行讨论对于避免不必要的终止妊娠很重要。我们报告了一例罕见的产前诊断上腹部寄生孪生,其中寄生胎有骨盆和下肢。出生时,自体部分有脐膨出,仅包含来自寄生胎的肠袢。
