Multiple Territory Ischemic Stroke Aggravated by Severe Anemia

While acute anemia is regarded as a precipitating factor of ischemic stroke, there have been few reports on the evolution of infarction in the acute period of ischemic stroke by anemia. We describe a 71-year-old man with acute multiple territory infarction who had progressive neurologic deficits of paraparesis and dysarthria. This case suggests that sustained severe anemia due to intractable intestinal bleeding is an important cause of aggravation of ischemic stroke.

Recurrent Cerebral Infarction in Polycythemia Vera

Polycythemia vera (PV) is a chronic myeloproliferative disorder that is characterized by increased production of leukocytes, erythrocytes, and platelets. Arterial and venous thromobotic complications are common in the clinical course of this disorder. There have been a few reports of acute ischemic stroke with PV. A case of PV associated with progression of middle cerebral artery stenosis and recurrent ischemic stroke is presented herein.
