Medical appraisal of Chinese military aircrew with abnormal results of coronary computed tomographic angiography

Figure 1 Transport pilot coronary computed tomographic angiography examination reveals coronary artery stenosis. A: All coronary artery images show mixed plaques with four vessel lesions and mild to moderate stenosis of the lumen; B: Right coronary artery, mixed plaques in the proximal segment, calcified plaques in the middle segment, soft plaques in the distal segment, and mild to moderate narrowing of the lumen; C: Obtuse marginal branch mixed plaques in the proximal and middle segments, with mild to moderate narrowing of the lumen; D: Left anterior descending of coronary artery, mixed plaques in the proximal and middle segments, with mild to moderate narrowing of the lumen.

Figure 2 Coronary angiography, obtuse marginal branch 2. A: Preoperative bead like stenosis of 50%-60% in the proximal and middle segments; B: After drug balloon dilation percutaneous transluminal coronary angioplasty treatment, the narrowing of the lumen was significantly improved after dilation, showing A-type dissection and thrombolysis in myocardial infarction III blood flow.

Figure 3 Coronary angiography, right coronary artery. A: Before surgery, the stenosis in the proximal and middle segments was about 50%, the stenosis in the middle segment was limited by 50%, and the stenosis in the middle and middle segments was 40%-50%. Localized eccentric stenosis in the distal segment is about 80%. Visible posterior descending artery and posterior branch of left ventricle emissions; B: After drug balloon dilation percutaneous transluminal coronary angioplasty treatment, the lumen showed significant improvement after dilation, with visible A-type dissection and thrombolysis in myocardial infarction III blood flow.
