case_images: Preoperative CT angiography revealed (A) the pseudoaneurysm located at the anterior wall of the ascending aorta (indicated by the white arrow), with an adhered thrombus of maximum thickness 23 mm observed on its external surface. (B) Morphological measurements of the lesion were obtained from 3D reconstructed images, showing a maximum pseudoaneurysm neck diameter of 6 mm, maximum pseudoaneurysm sac diameter of 18 mm, and a distance of 39 mm from the aortic sinus to the pseudoaneurysm.

case_images: The diameter of the neck of the pseudoaneurysm measured 6 mm, whereas its maximum sac diameter reached up to 18 mm, with an adhered thrombus with a maximum thickness of 23 mm observed on its external surface (Figure 1).
case_images: Intraoperative angiogram displayed (A) the anterior wall location of the aortic pseudoaneurysm and (B) clear visualization upon contrast administration. Following coil embolization, the angiogram demonstrated (C) complete occlusion of the pseudoaneurysm sac with coils, leading to exclusion from arterial blood flow (indicated by the white arrow).

case_images: Interlock coils of varying sizes were introduced into the pseudoaneurysm cavity, including one measuring 20-400 mm, two measuring 15-400 mm, and two measuring 10-250 mm. Intraoperative angiography confirmed complete occlusion of the pseudoaneurysm sac with coils, effectively excluding it from arterial blood flow (Figure 2).
case_images: Postoperative CT angiography at the 1-year follow-up depicted (A) complete thrombosis and reduction in the size of the pseudoaneurysm sac. (B) 3D reconstructed image showed secure positioning of the coils without any evidence of migration (indicated by the yellow arrow).

case_images: Subsequent assessment by CTA 1-year postoperatively demonstrated complete thrombosis and reduction in the size of the pseudoaneurysm sac (Figure 3).

case_images: Currently, the patient is being followed up at regular intervals. Cardiac surgery will only be considered in case of occurrence serious, late postoperative complications (The timeline with relevant data from the episode of care is presented in Figure 4).
