Transsternal bilateral thoracotomy for pericardiectomy after coronary artery bypass grafting

Abstract

Surgery for constrictive pericarditis was conducted through a transsternal bilateral thoracotomy in a 45-year-old man who developed the condition 12 months after coronary artery bypass grafting with left internal thoracic artery and vein grafts. The grafts ran just beneath the sternum. To avoid injury to the bypass grafts during sternotomy and mediastinal dissection, we conducted a transsternal bilateral thoracotomy, which provided excellent exposure of the heart Complete pericardiectomy was done safely without cardiopulmonary bypass. Constrictive pericarditis following cardiac surgery is an uncommon complication posing difficult problems for the surgeon. The presence of a patent left internal thoracic artery bypass is particularly challenging. Transsternal bilateral thoracotomy is a useful approach in patients with constrictive pericarditis in whom a median sternotomy is contraindicated.
