Thromboendarterectomy was performed under cardiopulmonary bypass and a highly organised embolus was taken out from her right main pulmonary artery.

Note that the atheromatous plaques of the pulmonar artery intima at the right are indicative of the effect of such embolization--pulmonary hypertension.

This is an atheromatous plaque in a coronary artery that shows endothelial denudation with disruption and overlying thrombus formation at the right.
