case_images: Preoperative and postoperative data. (A,B) are preoperative pulmonary artery CTA images showing an aneurysmal dilation of the pulmonary artery, with a maximum width of 5.55 cm. (D,E) are postoperative pulmonary artery CTA images demonstrating restoration of normal diameter in the main pulmonary artery, approximately 2.6 cm. Images (C,F) are intraoperative images, with (C) showing the pulmonary artery aneurysm under direct visualization, and (F) displaying the pulmonary artery after vessel replacement.

case_images: The computed tomography angiography (CTA) scan of the pulmonary arteries revealed significant aneurysmal dilation of the main pulmonary artery and the bifurcation lumen (about 5.6 cm at the wider part), which was considered to be a pulmonary aneurysm; the walls of the main pulmonary artery and its branches appeared smooth and continuous, with no apparent filling defect within the lumen (Figures 1A,B). Additionally, there is aneurysmal dilatation of the pulmonary arteries (Supplementary Figure S1). Intraoperatively, it was noted that the main pulmonary artery exhibited significant dilatation from 2 cm above its origin to the bifurcation of the right and left pulmonary arteries, with a maximum diameter of approximately 5.5 cm, and no palpable thrill was detected at the root, and there was a slight dilation observed in the left and right pulmonary arteries (Figure 1C). The artificial blood vessel was re-sutured and wrapped (Figure 1F). Postoperative follow-up pulmonary artery CTA showed that the diameter of the main pulmonary artery returned to normal (Figures 1D,E).
case_images: Pulmonary artery vascular management schematic. (A) Direct excision and suturing of the dilated pulmonary artery. (B) Replacement of the ascending pulmonary artery with an artificial blood vessel and wrapping. (C) Replacement of the ascending pulmonary artery with an artificial blood vessel without autologous vessel wrapping. (D-F) represent schematic illustrations of involvement of the left pulmonary artery, right pulmonary artery, or bilateral pulmonary artery branches, respectively, with subsequent replacement.

case_images: Pathological findings showed thinning of the pulmonary artery wall with no other significant abnormalities (Supplementary Figure S2).
