Case Reports
[A case report of hyperosmolar hyperglycemic non-ketotic coma after aortic valve replacement].
A 56-year-old man without a past history of diabetes mellitus underwent aortic valve replacement. On the 8th postoperative day, the patient became confused with a peak blood glucose level of 600 mg/dl and peak serum osmolarity level of 411 mOsm/l, without ketotic urine. The diagnosis of hyperosmolar hyperglycemic non-ketotic coma (HHNKC) was made, and the patient was immediately treated with massive infusion of 0.45% saline water and continuous insulin administration, and the patient could completely recover. It is important to prevent and keep in mind the complication of HHNKC for the postoperative care after open heart surgery.

Case Reports
[Surgical treatment of aortic arch aneurysm associated with the aberrant right subclavian artery].
A 64-year-old man, who had an aneurysm of aortic arch associated with the aberrant right subclavian artery, was treated successfully. He was pointed out to have an aneurysm of aortic arch three years ago. Three years later angiograms and computed tomography revealed that it became larger compared with the initial finding. ⋯ Aberrant subclavian artery was not involved in the aneurysm. But because the left subclavian artery was involved in it, a woven Dacron graft was interposed between the ascending aorta and left subclavian artery. Postoperative course was uneventful and there were no complications.
