Figure 1 Computed tomography pulmonary angiograms and vascular Doppler ultrasound. A-C: Computed tomography pulmonary angiograms showing extensive bilateral filling defects in the segmental arteries of the right upper lobe (A), segmental arteries of the right lower lobe (B), and segmental arteries of the left lower lobe (C); D: Doppler ultrasound revealed a deep venous thrombosis in the brachial vein of the right upper limb.

Figure 2 Computed tomography pulmonary angiograms, vascular Doppler ultrasound, and surgical wound. A: Computed tomography angiography demonstrated massive thrombosis in the segmental arteries of the right upper lobe, segmental arteries of the left upper lobe, and segmental arteries of the left lower lobe (red arrow heads); B: CT angiography revealed filling defects in the segmental arteries of the middle lobe and segmental arteries of the right lower lobe (red arrow heads); C: Doppler ultrasound revealed a venous thrombosis in the right vena basilica; D: Subcutaneous ecchymosis caused by anticoagulant therapy.
