Persistent cauda equina syndrome following bilateral aortoiliac dissection as a complication of cardiac angiography.

Cardiac angiography is accepted as an invasive yet safe procedure with well-characterized complications. We present a complication heretofore not described to our knowledge, in which a patient experienced the cauda equina syndrome following bilateral aortoiliac dissection during cardiac angiography. Similarities are noted between this complication and those documented in abdominal aortic aneurysm repair surgery.
