Thrombotic lesion

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

A thrombus is a blood clot in an intact blood vessel. The presence of angiographically evident thrombus (AET) is associated with embolization and impaired myocardial perfusion.^[1]^[2]

Thrombus Grading

In order to more objectively and quantitatively characterize thrombus on a coronary angiogram, the PERFUSE study group developed the following thrombus grading system:^[3]

Management of the Thrombotic Lesion

The presence of angiographically apparent thrombus is associated with poorer outcomes in patients undergoing PCI. Thrombus often embolizes distally and causes no reflow and associated myonecrosis. There are two broad strategies to reduce thrombus burden: mechanical strategies and pharmacologic strategies.
