Since February 1987, coronary angiography has been performed on 103 patients with aortic and peripheral vascular disease. In this study these patients were evaluated for risk factors and operation procedures. There were 77 patients with arteriosclerosis (ASO), 25 with aneurysm, and one with ASO plus aneurysm. Forty our of 77 ASO patients and 13 out of 25 aneurysm patients had over 50% coronary artery stenosis. The patients with significant coronary diseases had hypertension, diabetes mellitus (DM) or 2 of the following factors; smoking, hypertension, hyperlipidemia, and DM. CABG was performed on 8 cases prior to operation for vascular disease. Conclusion; The patients with aortic and peripheral vascular disease had a high frequency of coronary artery disease, 52%. The patients with risk factors had a high possibility of coronary artery disease. As a rule, a two-step approach was employed, namely, operation for a peripheral vascular disease was preceded by CABG or PTCA, if it could be indicated.

A 72-year-old man was admitted because of right hypochondralgia. A tumor in the right retroperitoneal space was revealed by abdominal ultrasonography, CT and MRI. Blood pressure was normal (140/86 mmHg) before operation, but during operation, systolic blood pressure suddenly rose to 240 mmHg. At this time, it was suspected that the tumor was an ectopic pheochromocytoma. Histological findings showed pheochromocytoma and bilateral normal adrenal glands were visualized on postoperative131I-adosterol scintigraphy.

Large ventricular septal defect (VSD) repair has been performed in 43 infants under two years of age. Twostaged repair was done for 11 infants and the primary definitive repair for the remaining 32. One hospital death occured among the 43 infants. Postoperatively, the incidence of cathecolamine dosing was, significantly higher, and a prolonged mechanical ventilation was required in the infants under 12 months (Group I), compared to those over 12 months of age (Group II). Regression of pulmonary hypertension after repair was similarly achieved in the two groups. Complete right bandle block tended to occure more frequently in Group I. Exhocardiographic evaluation of the left ventricular function revealed that left ventricular diastolic dimension and ejection fraction returned within normal limits one or two years after surgical repair in both groups. These data suggest that eraly surgical repair for VSD in the first two years of life is an appropriate surgical treatment where satisfactory clinical results can be expected.
