case_images: Imaging and pathological data of the patient. (A-C) Lung window (A), mediastinal window (B), and 3D window (C) of CTPA after admission showing simultaneous filling of the pulmonary artery and pulmonary vein in the right lung and the lower lobe of the left lung fill. (D) X-ray of the chest on the first postoperative day showing exudative changes in both lungs. (E) Pathological examination showing dilated blood vessels, different thicknesses of the blood vessel wall, partial anastomosis of the dynamic venous blood vessel wall, thickening of the intima of some blood vessels, and congestion and bleeding in the lung, conforming to the standard of PAVF with hemorrhage and secondary pulmonary hypertension. Scale: x40. (F) Chest CT showing a small amount of pleural effusion on both sides, slight enlargement of the hilum of both lungs after double-lung transplantation, interstitial changes in both lungs with exudation, local pericardium thickening, and locally thickened pleura on both sides.

case_images: After admission, CTPA indicated simultaneous filling of the pulmonary artery and pulmonary vein in the right lung and the lower lobe of the left lung, scattered patchy fuzzy shadows in both lungs, especially in the upper lobe of the right lung, and high-density shadows in the posterior mediastinal area (Figure 1A-C). Pathological examination showed the typical histological appearance of PAVF with hemorrhage and secondary pulmonary hypertension in both lungs (Figure 1E). On the first postoperative day, an X-ray of the chest showed exudative changes in both lungs (Figure 1D). Multislice spiral CT of the chest showed a small amount of pleural effusion on both sides, slight enlargement of the hilum of both lungs after double-lung transplantation, interstitial changes in both lungs with exudation, local pericardium thickening, and locally thickened pleura on both sides (Figure 1F).
