Reoperations were performed due to infection(n=10), after valve surgery (n=16), after coronary surgery(n=9), due to Marfan syndrome(n=3), after aortic surgery(n=7), after congenital surgery(n=4), and for other reasons. In the reoperations, the same surgical site was exposed in 65%, the femoral vessels were exposed before re-sternotomy in 77%, the inflow was on the ascending aorta in 35%, and cardiopulmonary bypass was initiated before re-sternotomy in 37%. Systemic cooling was needed in 4 patients and some maneuvers for patent internal thoracic artery grafts in 6 patients. The operation time of 9.6±2.5 h and the cardiopulmonary bypass time of 295±111 min, respectively. We experienced intraoperative injuries in 16 patients(31%). Platelet transfusion was needed in 90% and a second CPB in 15%. Postoperative complications included hemorrhage(14%), infection(13%), stroke(4%), respiratory failure(44%), and renal failure(1%). The hospital mortality was 7.7%(4/52)due to uncontrolled infection, liver failure, pulmonary hemorrhage, and left ventricular rapture. The 2-year survival rate was 83.1% with the mean follow-up of 24±18 months. In conclusion, although the risk of injuries at re-sternotomy was not high, limited surgical field due to adhesions resulted in fatal injuries and in the cardiac reoperations we experienced. We need to improve our strategies for further reduction in mortality and morbidities in reoperations. Jpn. J. Cardiovasc. Surg.
A 72 year-old man presented with aortic pseudoaneurysm and aortopulmonary fistula, due to dehiscence of the both coronary button anastomosis, at 15 years after aortic root replacement with Carrel patch procedure for annuloaortic ectacia. At reoperation, a fistula was found on the pulmonary trunk. The pulmonary artery defect was closed with interrupted 3-0 polypropylene sutures placed through strips of Teflon felt. The left and right coronary button had completely detached from the graft. The coronary ostial hole of composite valve graft was closed using a new prosthetic patch. Two coronary artery bypass were placed on LAD and RCA using saphenous vein grafts.Coronary pseudoaneurysm with fistulization to the pulmonary artery after a modified Bentall operation is a rare complication, only a few cases has been previously reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
