Bilateral occipital-parietal hemorrhagic infarctions following chiropractic cervical manipulation.
A 26-year-old woman presented with acute headache and hand-motion vision in both eyes. One day prior to presentation she went to her chiropractor for cervical manipulation. The patient had received 20 chiropractic manipulations over the previous two years. CT scan and MRI showed bilateral, symmetric occipital-parietal hemorrhagic infarctions. Angiography revealed severe focal stenosis in the distal vertebral arteries bilaterally at the superior C1 level possibly representing dissections. There was also a pseudoaneurysm of the left vertebral artery at the C1 level. Risk factors included chiropractic manipulation, recent fever, and therapies for polycystic ovarian disease. The patient showed slow, steady improvement in her vision. Twenty days following admission, vision was 20/20 OU. The improvement in her vision most likely reflects the reduction in swelling and absorption of blood at the site of the strokes.
