| Popis: | The patient, a 13-year-old boy had been in good health until August '73. He was a base ball player in middle school. On Nov. '73 he runnel at full about 400m as physical exercise in school, he had suddenly suffered from dyspnea, chest pain and unconsciousness. He admitted to Hirosaki University Hospital for the precise examination of the chest pain on Feb. '74.Physical examination at this time revealed the patient to be 151.5cm tall and 39.5kg in weight. He was well-nourished, well developed. The lips were not cyanotic. Lungs were clear and no rales. Blood pressure were 110/52mmHg. Heart rate was regular and no thrills. A grade 2/6 systolic ejection murmur was heard at the left sternal border. A thoracic deformity was not noted. Abdomen was soft and not tender. The neurologic and visual fields were within normal limits. Laboratory findings included a hemoglobin of 11.7g/100ml, serum electrolytes, calcium and urinalysis were normal. An electrocardiogram after Master's double step exercise showed the ST-T segment depression in leads 2, 3, aVF, V4, V5 and V6. Roentgenogram of the chest demonstrated the round shadow of calcium in the cardiac shadow. On selective coronary angiogram, the diagnosis of the shadow of calcium was aneurysm of the left circumflex coronary artery. Operation was performed on June 11 '74 and he died in cardiac arrest 6 hours after.Postmortem examination revealed the heart which was 10×9.5×3.5cm. The coronary arteries had the usual anatomical distribution. There was thumb tip sized thrombus which was firm, gray and smooth in suface at the portion between circumflex coronary artery and obtuse marginal artery. The coronary artary was not thick-walled and was not associated inflammation. There were recanalized channels in the old coronary artery. Etiology of aneurysm formation and thrombus are unknown, and suggestion is made to be of hemostatic abnormality origin. |
