SIRENOMELIA: AUTOPSY OF TWO CASES
Daisy Dwivedi and *Bal Chander
Sirenomelia is one of the unusual congenital disorders characterized by varying degree of lower limbs fusion along with visceral anomalies. We are presenting two cases with stress on the lower limb musculature and vascularity. Almost all major thigh muscles could be identified except sartorius which was not well delineated. A single midline artery starting from pubic region and ending around distal ends of tibia and fibula was noted. The artery bifurcated into larger anterior and smaller posterior branches around upper thigh. The anterior branch further bifurcated below knee into larger anterior and smaller posterior branches. Femur along with tibia and fibula were present in pairs. Owing to abnormal vascular features, such cases can be challenging to manage.
