Sirenomelia synonyms

Sirenomelia, also known as mermaid syndrome, is an extremely rare congenital malformation characterized by the fusion of the lower limbs, resulting in a single lower limb resembling a mermaid's tail. This condition affects approximately one in every 100,000 live births, making it an exceptionally rare occurrence.

Sirenomelia is a complex disorder that involves various abnormalities in the affected individual's lower body. The fusion of the legs is often accompanied by severe malformations of the genitourinary system, gastrointestinal tract, and spine. These abnormalities can lead to life-threatening complications, including kidney and bladder malformations, absence of certain organs, and spinal cord abnormalities.

Diagnosis of sirenomelia is typically made during prenatal ultrasound examinations, where the characteristic fusion of the lower limbs can be observed. However, due to the severity of the condition, most affected pregnancies result in stillbirth or neonatal death. Survival beyond infancy is extremely rare, and those who do survive face significant challenges in terms of mobility and organ function.

Treatment options for sirenomelia are limited and primarily focus on managing associated complications. Surgical interventions may be performed to address specific abnormalities, such as kidney or bladder malformations. However, the prognosis remains poor, and the overall management of sirenomelia requires a multidisciplinary approach involving various medical specialists.

In conclusion, sirenomelia, also known as mermaid syndrome, is an exceptionally rare congenital malformation characterized by the fusion of the lower limbs. It is associated with various abnormalities and life-threatening complications. Early diagnosis and a comprehensive medical approach are crucial in managing this complex condition.
