Key result
Multiphase spiral CTA successfully identifies active vein graft bleeding in recurrent delayed cardiac tamponade post-CABG.
Why the study?
Delayed cardiac tamponade following cardiac surgery presents major diagnostic challenges, and recurrent tamponade physiology creates further management difficulty in medically complex patients.

CTA is a valuable diagnostic modality for identifying the source of bleeding and assessing graft patency in patients with delayed, recurrent cardiac tamponade after CABG when transthoracic echocardiography is insufficient.
May warrant vigilance for recurrent tamponade after post-CABG drainage; extends sparse case reports on this rare complication.
Delayed cardiac tamponade after cardiac surgery is a rare complication with significant diagnostic challenges. The recurrence of cardiac tamponade physiology after initial intervention creates another degree of difficulty in the management of already medically complex patients. We present the case of a 65-year-old male who underwent four-vessel coronary artery bypass grafting that was complicated by the delayed presentation of cardiac tamponade requiring mediastinal exploration. Following this he developed a recurrence of cardiac tamponade with bleeding from a vein graft identified on multiphase spiral computed tomography angiography.

Gorton et al. (2023) conducted a case report in Delayed cardiac tamponade after coronary artery bypass grafting (n=1). Computed tomography angiography (CTA) was evaluated. Multiphase spiral computed tomography angiography successfully identified active bleeding from a vein graft in a patient with recurrent delayed cardiac tamponade after coronary artery bypass grafting.
