[Combined superior-transseptal approach to left atrial myxoma].

A 60-year-old woman was referred to our hospital for treatment of an intracardiac tumor Echocardiography revealed a 47 x 30 mm tumor in the left atrium which had a short stalk attached to the atrial septum. At operation, a large left atrial myxoma was extirpated using a combine superior transseptal approach. Through this incision, exposure of the left atrial myxoma and it stalk was excellent and removal of the myxoma was easily performed with minimal minpulation. Postoperative arrhythmias related to the operative procedures were not observed. The patient recovered uneventfully. The operative technique and indications of the combined superior transseptal approach to the left atrium are discussed in this paper.

Aortic valve replacement for aortic regurgitation due to Kawasaki disease. Report of two cases.

Two cases of severe aortic regurgitation due to Kawasaki disease are reported. Both patients were diagnosed as having Kawasaki disease in their infancy, and were followed up by a pediatrician. Aortic regurgitation was detected 18 months in one case and 36 days in the other case after onset of the illness. With the passage of time, the aortic regurgitation increased and aortic valve replacement was scheduled in both patient at the age of 13. On admission, two-dimensional echocardiography showed thickening of the aortic cusps, and severe aortic regurgitation was detected by color flow Doppler studies. Successful aortic valve replacement was performed, and histological studies of the cusps showed sequelae of valvulitis. In conclusion, aortic regurgitation is a rare complication of Kawasaki disease, and the aortic valve function, especially occurrence of aortic regurgitation, should be carefully observed in patients with a past history of Kawasaki disease.

[Surgical treatment for active infective endocarditis].

Between April 1975 and December 1995, 33 patients with active infective endocarditis underwent surgical treatment at our hospital. The location of diseased valve was shown as ; 18 in aortic, 11 in mitral, and 4 in aortic and mitral position. Of these, 14 patients had an annular abscess or mycotic aneurysm. All patients achieved antibiotic therapy previously, and predominant indication for operation was congestive heart failure. All patients underwent valve replacement. The reconstructive procedures for 14 patients with paravalvular involvement were as follows ; direct closure : 5 cases, direct closure+tilted prosthesis technique : 5 cases, and another 4 cases were, patch closure of VSP resulting from a septal abscess, patch closure+translocation, translocation, and reconstruction of annulas with pericardial patch. There were five (15.2%) operative and hospital deaths and actuarial survival rate was 81% and 61% at 5 and 10 years after operation. Including one who died early after operation, there were 5 cases with postoperative paravalvular leakage and its main cause were persistent infection. In conclusion, it considered that the principles of treating active infective endocarditis is to decide the optimal timing for operation, debride the infected tissue, and close the defect completely.

[A case of a traumatic diaphragmatic true hernia manifesting itself 12 years after the accident].

A case of surgical treatment of a traumatic diaphragmatic true hernia was presented, which manifested itself as symptoms of left chest oppression 12 years after the accident. The patient was a 66-year-old woman, who met traffic accident in 1976. She was first pointed out abnormal shadow on the chest X-ray in 1981 and began to feel chest oppression in 1988. Barium examination of the upper gastrointestinal tract and chest CT scan revealed a part of corpus ventriculi and colon herniated into the left hemithorax. Diaphragmatic hernia was diagnosed and the operation was performed through the thoracic approach in June 1991. The diaphragm was found to have a hernia sac and a defect at the central tendon. The hernia sac containing the stomach and colon was opened to reduce it's contents into the abdominal cavity. The defect was closed by mattress suture with pledgets and continuous over and over suture. The patient ran a favorable post operative course. A true type among traumatic diaphragmatic hernia is a very rare case in the literature.

[A case of recurrent lung cancer complicated acute interstitial pneumonia, just after injected peplomycin].

A 77-year-old man with recurrent lung cancer was administered peplomycin (PEP) 15 mg 1A only one time, from a link in the chain of chemotherapy. But just after it was occurred dyspnea, and heard crepitus by auscultation. And it was recognized of ground glass appearance and air-bronchogram in the entire lung field by chest X-ray photograph, so made a diagnosis of acute diffuse interstitial pneumonia by clinical. He died two days after in spite of emergency treatment, that is high dose steroid, O2 flow etc. We discussed the acute pulmonary side effect of peplomycin which is one of the carcinostatic antibiotic, according to this clinical progress.

[Useful CT findings in a case of idiopathic perforation of the descending colon].

Idiopathic perforation of the descending colon is an uncommon disease. The disease has tendency to complicate with severe pan-peritonitis at relatively early stage. So early diagnosis and treatment is required. We encountered a 83-years-old female patient with idiopathic perforation of the descending colon. CT revealed the findings suggestive of free air in the retro-peritoneal space. We thought CT may be useful diagnostic approach to make correct diagnosis of the perforation of the colon.
