Late quadriplegia after adult coarctation repair

Quadriplegia developed suddenly 1 month after coarctation repair in a 53-year-old human. Cervical cord ischemia caused by thrombosis in an enlarged anterior spinal artery collateral was diagnosed on magnetic resonance scan and spinal angiography. After urgent cord decompression and anticoagulation there was neurologic improvement over a period of several months. Urgent investigation of neurologic abnormalities occurring late after coarctation repair may enable intervention to avert permanent neurologic sequelae.
