2. Fig 1
A typical example of selective left pulmonary angiogram. A, Before embolization. B, After embolization of multiple-curled coils and tissue adhesive in the main left pulmonary artery and the first 3 cm of the left lower lobar artery. The angiogram shows a complete obstruction of left pulmonary artery.

Surfaces of the left lungs of 2 representative piglets. One of the control group (A) and the other 5 weeks after left pulmonary artery obstruction with chronic thrombus (B). Large systemic arteries are visible on the lung surface under the visceral pleura on (B).

4. Fig 3
A typical example of pulmonary thromboendarterectomy in a piglet. The whitish chronic thrombus is adherent to the intima, and the thromboendarterectomy has to be performed through the media. Note extensions of the thrombus into the upper and the lower arteries.

6. Fig 5
Cross sections of obstructed pulmonary in a piglet. Note the disruption of the intima by the thrombus, the recanalization of the thrombus by mutiluminal channels, the infiltrate of the thrombus by fibroblasts and inflammatory cells, and the hypertrophy of the vasa vasorum within the arterial wall. (Hematoxylin and eosin stain; original magnification, ×12.5.)
