Coronary angiography and brain computed tomography were preoperatively performed to evaluate the clinical condition of coronary artery disease and cerebrovascular disease in 101 patients (mean age, 68.4 years) with revascularization for arteriosclerosis obliterans. Eighty patients had hypertension, 12 had diabetes, and 26 had hyperlipidemia. Seventy-one patients (70.3%) had coronary stenosis. Significant stenoses in major coronary artery branches were confirmed in 35 patients, including 13 patients with old myocardial infarction. Coronary artery bypass grafting and percutaneous coronary angioplasty were performed in 2 and 7 patients with critical stenosis, respectively. Of 57 patients, who underwent brain computed tomography, abnormalities were found in 52 patients (91.2%), including cortical infarction in 9, lacunar infarction in 35, and leukoaraiosis in 27 patients. During the follow-up period 13 patients died (including 3 cases of myocardial infarction and 3 cases of stroke). Actuarial survival rate at 5 years was 80.4%. The influence of ischemic heart disease and cerebrovascular disease on early and late mortality after surgical reconstruction for peripheral occlusive vascular disease is significant. Using visual diagnostic techniques, such as coronary angiography and brain computed tomography, long term survivor should be closely observed for multiple arteriosclerotic vascular diseases.

A 64-year-old man with arteriosclerosis obliterans with huge multiple ulcers of the left leg was admitted for surgery. He had ichthyosis, and was diagnosed as X-linked ichthyosis by reduced steroid sulfatase activity and clinical examinations. Angiography revealed occlusions of the left common and external iliac arteries, left femoral artery, and right femoral artery. Aorto-left femoral bypass with a gelatin impregnated Dacron prosthesis and left femoro-popliteal bypass with a reversed saphenous vein graft were performed. Postoperatively the leg ulcers gradually healed and the patient was discharged in good condition. Leg ulcers with arteriosclerosis obliterans in patient with X-linked ichthyosis should be treated by the arterial reconstruction in the same way as in case with normal skin.

Hemolysis, hemoglobinuria, skin eruption and hypotension were noticed following transfusion of 11 units of fresh blood during mitral valve replacement in a 57-year-old man. Irregular antibody incompatibility was suspected. Further investigation revealed anti Lewis-a antibody. Three of 11 units of transfused blood were positive for the indirect Coombs test. The patient recovered without renal failure, and was discharged. One year later, he had urgent re-MVR due to malfunction of the prosthetic valve. Hemolytic transfusion reaction had occured after the administration of donor blood which had been showed to be compatible by cross matching. This means that antibody titer diminishes with time, and that posttransfusion screening tests should minimize the unexpected hazards of incompatible blood transfusion. We recommend that antibody screening tests should be routinely performed after open heart surgery, to minimize the risk of hemolysis during future reoperation.

Problems with postoperative respiratory management of three patients after division of double aortic arch are described. Tracheomalacia was present in two of three cases with intracardiac anomalies of different types. Intracardiac anomalies of each patient were as follows: Patient 1, ventricular septal defect (VSD), atrial septal defect and pulmonary valve stenosis (PS); Patient 2, VSD, corrected transposition of the great arteries with PS; Patient 3, VSD with pulmonary hypertension (PH). In patient 1 and 2, no concomitant surgical intervention was performed for tracheomalacia. In these patients respiratory support had been continued for 41 and 60 days respectively. In patient 3, remaining VSD with PH was the cause of unexpected respiratory problem even after the successful division of the double aortic arch, and necessitated emergency VSD closure 49 days after the initial operation. The patient was extubated on postoperative day 12. Tracheomalacia is a life-threatening problem even after surgical division of the double aortic arch. Although prolonged respiratory support was needed, our two cases were successfully extubated without concomitant surgical intervention of tracheomalacia. Severe cases should be operated on simultaneously with the relief of vascular ring and tracheomalacia. Intracardiac anomalies are also the causes of prolonged intubation. Patient 3 should have been treated by pulmonary artery banding along with the division of aortic arch. In conclusion, precise evaluation of the existence and severity of the tracheomalacia and intracardiac anomalies is of utmost importance to overcome postoperative respiratory failure and for eventual satisfactory results.

From January 1979 through May 1982, 36 premature infants less than 2.5kg and less than 35 weeks of gestation, including 24 patients with respiratory distress syndrome, underwent ligation of patent ductus arteriosus (PDA) due to being unresponsive to medical treatment. Ten patients died postoperatively mainly from intracranial hemorrhage and necrotizing enterocolitis. Surviving 26 patients were examined for developmental sequelae based on questionnaire survey. One infant died of respiratory failure secondary to severe bronchopulmonary dysplasia 28th month after operation. We found no evidence of recurrent ductal patency following ligation during the follow-up period. Twenty four patients exhibited normal motor and mental development to attend the ordinary elementary school everyday, but one patient shows mental retardation. Most of patients suffered from the frequent upper respiratory infection in childhood to require rehospitalization. There are no patients with hoarseness, but 2 patients developed funnel chest and one required the operation. One third of the patients had ophthalmological handicap (myopia or strabismus). Surgical ligation of PDA in premature infants seems to reduce the duration of postoperative mechanical ventilation and the incidence of bronchopulmonary dysplasia. Analyzing long-term follow-up indicates that infants who undergo PDA ligation grow almost normally and do not appear to be at increased risk for sensorineural handicaps. Therefore we emphasize that surgical ligation of PDA is an effective and appropriate treatment of choice for significant PDA in premature infants.

A 63-year-old woman who was diagnosed a having impending rupture of abdominal aortic aneurysm underwent urgent anatomic reconstruction. Histopathological findings revealed abscess formation around the aneurysmal wall, and a definitive diagnosis of mycotic aneurysm was established. Successful management of this rare aortic disease depends on early accurate diagnosis, control of infection and careful surgical management.

Objective:
There have been a few reports on the specificity of the meridians and Acupuncture-points. In order to identify the specific effects of the meridians and Acupuncture-points, the functional relations between “the gallbladder Meridian and gallbladder” were investigated using the gallbladder's form as an index.
Materials and Methods:
Ten healthy male adult volunteers participated in the experiments in fasting conditions. The target organ was the gallbladder, and its form was measured with the ultrasonic diagnostic apparatus (Toshiba SSA-90A). The images of the gallbladder form were taken at the point when the major long axis of the cross-section of the gallbladder reached the peak. The cross-sectional area of the gallbladder was measured with the image analyzer. The measurement of the gallbladder form was conducted after 15 minutes lying on the back, taking images for 10 minutes before stimulation, for 30 minutes during and after stimulation, every two to five minutes. The acupuncture stimulation was given at the points of G34, G36, G37, G40 and G44 on the right side of the body. After getting the deqi, 1 minute of sparrow pecking needle technique and 1 minute of leaving needle technique were conducted three times. The effect of the G40 under the egg yolk loading were also investigated.
Results:
1) The stimulation of the G34, G36, G37, and G44 showed no effects on the gallbladder form. 2) The stimulation of the G40 caused the distension of the gallbladder form. 3) The stimulation of the G40 showed the suppressive effect on the contraction of the gallbladder due to the load of egg yolk.
As described above, the results of this study showed that there is an acupuncture-point on the gallbladder meridian to cause the distension of the gallbladder specifically. It suggests the existence of the specificity of acupuncture-point.
