[A case of left lung cancer associated with an aneurysm of the thoracic aorta].

A 61-year-old man was admitted to our hospital because of a left lung cancer. The chest x-ray film showed an irregular mass in the left upper lung field and the ill-defined left upper mediastinal border. A large portion of the aorta seen in the CT section above the aortic arch was understood to be aortic elongation.

[Three cases of catamenial pneumothorax].

Three cases of catamenial pneumothorax were presented. A 42-year-old woman with intrapelvic endometriosis had recurrent right-sided pneumothorax with menstruation more than six times. At the operation only a bleb was noted at the apex of the right lung.

[A case of medial pneumothorax in the aged].

A 81-year-old man was admitted because of left recurrent pneumothorax with pleural adhesion. A drainage tube was inserted through the left lateral thoracic wall. The lung seemed to be fully expanded in the AP chest X-ray film but his dyspnea was not relieved.

[A successful treatment of Cabrol's procedure for annuloaortic ectasia with an acute aortic dissection (Stanford type A)].

A 67-year-old female who has an Annuloaortic ectasia with an acute aortic dissection was urgently admitted to our hospital. She was also suspected to have developed into an acute cardiac tamponade. An aortic dissection was arised from just above the right coronary artery orific and extended to the innominate artery and the right common carotid artery.

[A successful one stage treatment in angina pectoris and intermittent claudication of both legs].

A successful surgical case of concomitant aorto-coronary bypass grafting and aorto-right iliac, left femoral bypass grafting was presented. A sixty-two years old male admitted to our institution with complaints of angina pectoris and intermittent claudication of both legs who had a history of acute inferior myocardial infarction for which emergency percutaneous coronary balloon dilatation was carried out prior to this admission. In this admission, he was found out to have diabetes mellitus moreover and he hoped to have one staged operation for two different type of the disease.

Measurement of regional myocardial blood flow. Application of the electrolytic hydrogen clearance method in man.

To assess myocardial perfusion intraoperatively and to evaluate the adequacy of coronary bypass grafting, we measured regional myocardial blood flow by the electrolytic hydrogen clearance method in 49 patients. Group I comprised 10 patients with nonischemic heart disease and group II, 39 patients with ischemic heart disease undergoing coronary bypass grafting. Group II was subdivided according to the percent stenosis of the coronary arteries supplying the ventricular regions: group IIa, less than 75% stenosis; group IIb, greater than or equal to 75% stenosis.

Intraoperative evaluation of coronary bypass grafts by measuring myocardial blood flow using the electrolytic hydrogen clearance method.

The regional myocardial blood flow (MBF) was measured in 33 patients who underwent coronary bypass graft surgery in order to evaluate the efficiency of coronary bypass grafts in restoring MBF. MBF was measured by the electrolytic hydrogen clearance method during the coronary bypass surgery. The mean prebypass MBF was 161 +/- 19, 162 +/- 12, 80 +/- 12, 43 +/- 14, 104 +/- 18 ml/min/100 g in segments supplied by the left anterior descending coronary artery (LAD) showing less than or equal to 50 per cent, 75 per cent, 90 per cent, 99 per cent, and 100 per cent stenosis with collaterals, respectively.
