[An aged case of coronary-aorta bypass grafting surgery (CABG) with severe chronic obstructive pulmonary disease]

This paper reports CABG which was successfully performed on a male patient of 70-year-old with severe chronic obstructive pulmonary disease (FEV1.0% 43%) and diabetes mellitus. The patient necessitated reintubation because of hypercapnea on 18 POD in spite of bronchodilator and physical therapies. Long respiratory care was continued after tracheotomy, and finally he could wean from the mechanical respiratory care utilizing acetazolamide (carbonic anhydrase inhibitor) on 59 POD.
