Amniotic band syndrome (ABS) has an incidence of 1/15,000. Deformities vary from rare but bizarre craniofacial defects or truncal defects to the commoner limb defects. The pathogenesis of ABS remains controversial. The following is a case of a 3-month-old infant with amniotic band syndrome with the typical limb reduction defects, a constriction band on the thigh associated with a persistent sciatic artery and bifurcation of the femur and the duplication of the knee and tibia on the contra lateral side. The anatomy of the persistent sciatic artery is demonstrated in magnetic resonance angiography and digital subtraction angiography. The vascular anomaly was unilateral. The patient underwent surgical correction of the constriction band by excision and multiple Z plasty. This case is the first description of the coexistence of ABS and persistent sciatic artery. Persistent sciatic artery has angiographic incidence of 0.05%. Is this purely a coincidence? Or perhaps their coexistence may serve to further the understanding of the mechanism of ABS.

D000652	Amniotic Band Syndrome	A disorder present in the newborn infant in which constriction rings or bands, causing soft tissue depressions, encircle digits, extremities, or limbs and sometimes the neck, thorax, or abdomen. They may be associated with intrauterine amputations.

D001158	Arteries	The vessels carrying blood away from the heart.	Artery
D012584	Sciatic Nerve	A nerve which originates in the lumbar and sacral spinal cord (L4 to S3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the TIBIAL NERVE and the PERONEAL NERVE.

D015901	Angiography, Digital Subtraction	A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.	Digital Subtraction Angiography,Subtraction Angiography, Digital
D018482	Muscle, Skeletal	A subtype of striated muscle, attached by TENDONS to the SKELETON. Skeletal muscles are innervated and their movement can be consciously controlled. They are also called voluntary muscles.
