Example scans for a typical patient with operable chronic thromboembolic pulmonary hypertension. a) Perfusion (Q′) and b) ventilation (V′) lung scans. R: right; L: left; ANT: anterior; POST: posterior; LPO: left posterior oblique; RPO: right posterior oblique. c) Computed tomography pulmonary angiography scan. d) Pulmonary angiogram.

a) Longitudinal incision in the right pulmonary artery, exposed between the superior vena cava and aorta. b) Developing the endarterectomy dissection plane in the left pulmonary artery. c) Removing the occluded endarterectomy “tails” from the left upper lobe segmental vessels.

Classification of pulmonary occlusive disease
Type Description Operable? 1 Major vessel clot Yes Readily visible on opening pulmonary arteries 20% of cases 2 Only thickened intima can be seen Yes Endarterectomy plane initially raised in the main, lobar or segmental vessels ∼70% of cases 3 Distal disease Yes Confined to segmental and subsegmental branches ∼10% of cases 4 Intrinsic small-vessel disease No Secondary thrombi may occur from stasis -
