Coronary heart disease with pulmonary embolism: A case report

Figure 1 Changes in computed tomography pulmonary angiography after treatment. A and B: Computed tomography pulmonary angiography (CTPA) after admission, indicating thickening of the pulmonary arterial trunk and multiple low-density filling deficiencies in the pulmonary artery in the right middle lobe and in bilateral segmental arteries; C and D: CTPA after 2 mo of follow-up, showing slight thickening of the pulmonary trunk and striated filling defects with lumen stenosis in several segmental pulmonary arteries and their branches bilaterally. Notably, a reduction in the extent of filling defects within both pulmonary arteries is observed compared to the initial CTPA.
