Giant saccular superior vena cava aneurysm: a rare clinical case

Background: Superior vena cava (SVC) aneurysm is a rare clinical disease. Only around 50 cases have been reported in the medical literature.

Case presentation: We report a 22-year-old man with SVC aneurysm with cardiac arrest as the first symptom accompanied by typical superior vena cava syndrome.

Conclusion: We suggest that patients with giant SVC aneurysm should avoid sudden changes in posture, and that surgical treatment should be implemented urgently.
