CTICasesChronic thromboembolic pulmonary hypertension (CTEPH) treated with thromboendarterectomy
Imaging findings
CT angiogram and V/Q perfusion scan demonstrate complete occlusion of the right interlobar pulmonary artery and left upper lobe pulmonary artery branches. Post-operative CT following pulmonary thromboendarterectomy shows dramatic recanalization of the vessels, decreased main pulmonary artery caliber, and resolved pulmonary hypertension.
Key takeaways
CTEPH is a progressive form of pulmonary hypertension caused by non-resolving pulmonary emboli. Surgical pulmonary thromboendarterectomy is curative, providing dramatic restoration of vessel patency and hemodynamic improvement.
