Abstract

A 45-year-old woman, who had had rheumatoid arthritis for 12 years, had three attacks of cerebral embolism over two months and died after the final attack. Intensive clinical laboratory investigations did not disclose any specific origins of emboli, but an autopsy revealed a nodule at the base of the aortic valve which was pathologically proved to be a rheumatoid nodule. The thrombi were present from the distal part of left internal carotid artery up to the proximal part of the left middle cerebral artery. They were rich in fiber, but poorly organized endothelial cell, raising the possibility that they originated from other parts and have recently reached there. On the top of the rheumatoid nodule, a thrombus was present. It was easily ablated and a small amount of fibrin stuck the nodule. Based on these results, we concluded that cerebral emboli were originally generated at the top of a rheumatoid nodule in the heart. In patients with RA, rheumatoid nodules are rarely seen in the heart. If present, they usually cause cardiac failure or atrioventricular block, and seldom result in cerebral infarction. This is the first case in which an autopsy proved rheumatoid nodule in the heart which had caused multiple cerebral emboli. We s...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Acute Stroke

A stroke occurs when blood supply to the brain is interrupted depriving the brain of oxygen and nutrients. This feed focuses cerebrovascular accidents including ischemic and paralytic stroke.
