Left axillary incision (minithoracotomy) for PDA division.

From 1955 to 1975, 417 patent ductus arteriosus (PDA) operations were performed at Sapporo Medical University. The last 118 operations (28.3%) were done by division through the left axillary incision without mortality. Forty patients were less than 2 years old and 14 were less than 1 year old. The ratio of girls to boys was 3.5:1. Because the majority of patients with PDA are girls, parents commonly show considerable concern over the size of the operative scar. Our clinical experience demonstrates clearly the feasibility and safety of an axillary incision in dividing a PDA, even in premature infants. A minithoracotomy through the axilla is recommmended.

Angiographic evidence of myocardial squeezing accompanying tachyarrhythmia as a possible cause of myocardial infarction.

The coronary arteriogram of a 52-year-old man with Basedow's disease and who was suffering from myocardial infarction following rapid atrial fibrillation, showed severe myocardial squeezing without organic stenosis. Angiographically, the functional obstructive lesion was always observed both at systole and diastole during atrial pacing, 150 beats per minute, and suggests that myocardial squeezing may be the cause of myocardial infarction following tachyarrhythmia.

Long-term results of bypass grafts for atypical coarctation of the thoracic aorta.

Long-term results of bypass grafts for atypical coarctation of the thoracic aorta are presented. Six of the 13 patients with atypical coarctation were treated with long bypass from the descending thoracic aorta to the abdominal aorta. One of them had correction of right renal stenosis with a saphenous vein graft. Late clinical results of surgery (average follow-up time 4 years, 5 months and the longest over 10 years) were excellent, except for one patient who died 3 1/2 years postoperatively of acute abdomen. This experience suggests that atypical coarctation of the aorta can be treated satisfactorily by the long thoraco-abdominal bypass graft technique. If unilateral or bilateral renal artery stenosis is found simultaneously, renal revascularization is also necessary to obtain normalization of the blood pressures.
