Polymorphonuclear leukocytes occlude capillaries following middle cerebral artery occlusion and reperfusion in baboons.

Abstract

The finding of capillary-obstructing polymorphonuclear leukocytes in the microvascular bed following middle cerebral artery reperfusion in focal ischemia in this model satisfies an essential requirement for postulating their role in early microvascular injury and the "no-reflow" phenomenon.
