Cardiac tamponade caused by a ruptured coronary aneurysm treated with open-chest hemostasis after esophageal cancer surgery: a case report.

Cardiac tamponade is a rare postoperative complication of esophagectomy, with no previous reports of association with coronary artery aneurysm rupture. We present a case of cardiac tamponade caused by coronary aneurysm rupture following esophageal cancer surgery. A 68-year-old man with no history of heart disease underwent robotic subtotal esophagectomy for esophageal squamous cell carcinoma. He experienced intermittent chest pain on postoperative day (POD) 17. Echocardiography revealed increasing pericardial fluid, and pericardiocentesis on POD 34 revealed bloody pericardial fluid. Contrast-enhanced computed tomography and coronary angiography revealed a ruptured coronary aneurysm causing cardiac tamponade. Emergency surgery with a median sternotomy achieved hemostasis, and the patient recovered successfully. Cardiac tamponade after esophageal surgery, particularly from coronary aneurysm rupture, is rare. Prompt diagnosis and treatment are crucial for patient survival. Despite its risks, median sternotomy was effective in achieving rapid hemostasis and patient recovery in this case.
