Aim: to summarize 7 patients undergoing pulmonary thromboendarterectomy (PTE) in Peking Union hospital and Chaoyang hospital.

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

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