Definition of Microinfarction

Tiny arterial occlusions that briefly block the flow of blood to the brain, causing transient ischemic attacks (TIAs), or to the heart. What microinfarction lacks in initial effect it makes up through frequency.

It may also affect other key organs such as the kidneys and liver.

Conditions that can result in microinfarction include severe atherosclerosisperipheral vascular disease (pvd)coronary artery disease (cad)intermittent claudication, and deep vein thrombosis (dvt).

Microinfarction also may occur after surgical operations or major trauma, when clot fragments break away from healing wounds. Doctors use anticoagulation therapy.
