ABSTRACT

We present a rare case of cardiac surgery for coronary artery single vessel disease and aortic valve stenosis after substernal gastric interposition for gastric cancer. An 80-year-old man, who had undergone esophagectomy and substernal gastric interposition 7 years previously, was referred to our institute for surgical treatment of coronary artery disease and aortic valve stenosis. Through a median sternotomy with cardiopulmonary bypass, we performed aortic valve replacement and coronary artery bypass grafting to the right coronary artery without injury to the gastric tube. Postoperatively, the patient was on respirator care and catecholeamine support for several days. Although urinary tract infection occurred, he recovered with antibiotic therapy. Finally, he was discharged on postoperative day 40. For cardiac surgery after substernal gastric interposition for esophageal cancer, even though the substernal gastric tube may preclude the usual median approach, median sternotomy is an appropriate alternative with close preoperative examination and careful dissection of substernal gastric tube.

ABSTRACT

During the past 7 years from January 1991 through October 1997, we treated 30 cases of aortic root reconstruction by the Carrel patch method. The cases included annulo-aortic ectasia (AAE), root aneurysm with aortic regurgitation (AR), aortic dissection with AR, and true aneurysm (ascending and arch) with AR. The surgical treatment consisted of 28 modified Bentall operations and 2 aortic root remodelings, similar to the Yacoub operation. The aortic root and valve were resected, the coronary arteries were dissected free, mobilized, and then implanted into the composite graft. Coronary anastomosis was performed by mattress suture reinforced by Teflon felt strips. In 5 cases it was necessary to undergo coronary artery bypass grafting for myocardial ischemia. Blood transfusion was unnecessary in 11 cases. Post operative death was seen in only one patient who underwent an emergency operation for cardiac tamponade due to aortic dissection on the 25th postoperative day. The operative mortality rate was 3.3%. The complications of anastomosis, for example leakage and dilatation of the coronary ostia, were not seen in our experience. Reoperation and late death were not observed during the follow-up period (average 23 months). Cerebral hemorrhage occurred in only one case, at 5 years after the operation, and all other patients had an uneventful postoperative course. The event-free rate is 75% (<i>n</i>=1) at 6 years. The operative procedure is considered feasible in any anatomic variation of aortic root diseases, even if dislocation of the coronary ostia is minimal, and this method holds hope for the prevention of anastomotic pseudoaneurysm formation and long-term survival. Although further long-term follow-up study is necessary, our experience suggests that the Carrel patch procedure has few late term complications.
