0 a thick mass of blood that forms in a blood vessel and may block the flow of blood in the blood vessel:
Arterial thrombosis is caused by a thrombus in an artery.
The thrombus seemed to resolve with the help of oral coumadin.
Further echocardiography 8 months later suggested that the thrombus had resolved.
In the other four patients with no symptoms of ischemia, the therapy was undertaken when thrombus was detected in a coronary aneurysm.
When no change in the state of the thrombus was detected after continuous intravenous infusion of urokinase for 10 days, the treatment was discontinued.
The duration of intravenous infusion of urokinase was determined by the disappearance of thrombus as judged by echocardiography.
The only means of detecting the earliest appearance of a thrombus in aneurysms, therefore, is intensive echocardiographic observation of the large aneurysms.
In the remaining six patients, cross-sectional echo did not demonstrate any formation of thrombus.
At autopsy, fibrous obstruction was noted proximal to the stent, and thrombus within the stent.
