We report the first case of a fetus with sirenomelia or mermaid syndrome, whose Afghanian parents were heavy user of a special form of snuff. The case was diagnosed as a mermaid syndrome but some of the features were common to both symmelia dipus and symmelia apus, for example, the single lower extremity had the normal femur, tibia and fibula, but the single foot was rotated medially. The digestive tube ended to a massive closed saclike structure and the anus was absence. The external genital organs were rudiment and the normal testes were undescended. Aorta was divided to branches, such that the external iliac arteries were very small in comparison to the internal iliac arteries. Inferior Vena cava was placed on to the left side of the aorta and unlike the majority of reported mermaid syndrome, the bladder was present. So, the researchers believe that the present case is a rare variant of the mermaid syndrome.
我们报告了首例患有并腿畸形或美人鱼综合征的胎儿，其阿富汗父母是一种特殊形式鼻烟的重度使用者。该病例被诊断为美人鱼综合征，但某些特征在双足并腿畸形和无足并腿畸形中都很常见，例如，单一的下肢有正常的股骨、胫骨和腓骨，但单足向内旋转。消化道终止于一个巨大的封闭囊状结构，且肛门缺失。外生殖器发育不全，正常的睾丸未降。主动脉分为分支，与髂内动脉相比，髂外动脉非常小。下腔静脉位于主动脉左侧，与大多数已报道的美人鱼综合征不同，膀胱存在。因此，研究人员认为本病例是美人鱼综合征的一种罕见变体。
