A case of distal aortopulmonary septal defect associated with aortic origin of right pulmonary ar- tery, patent ductus arteriosus and hypoplasia of aortic isthmus in a 50-day-old female infant is presented. Ligation of patent ductus arteriosus, resection and end-to-end anastomosis of hypoplasia of aortic isthmus, implantation of rlght pulmonary artery to main pulmonary artery and autologous peri- cardial patch repair of aortopulmonary septal defect were performed under cardiopulmonary bypass as one-stage approach. Deep hypothermic total circulatory arrest was applied during repair of hypoplasia of aortic isthmus. The p stoperative course was uneventful.

Confusion of a patent ductus arteriosus (PDA) for the descending thoracic aorta is a fatal error occurring occasionally in infants or neonates. As a result, the left pulmonary artery (LPA) may be misconceived as the PDA, and ligated. This surgical mishap of other hospital leads to serious congestive heart failure and loss of left lung function due to the underdevelopment in the peripheral vascular and alveolar structures in neonates and premature infants. In this report, 3 cases of LPA ligation and subsequent treatment are presented.

Bronchial artery aneurysm is a rare but life-threatening disease when it ruptures, and it requires prompt treatment to prevent from catastrophic ruptures. A 78-year-old woman was referred to our hospital to evaluate mediastinal massfound on chest computed tomography. We did a selective bronchial artery angiography and diagnosed as bronchial artery aneurysm. Aneurysmectomy with division of afferent and efferent arteries was performed through standard thoracotomy without cardiopulmonary bypass. The patient recovered uneventfully and was discharged on postoperative 8th day without any complications.

Aberrant right subclavian artery (ARSA) is an anomaly with a reported incidence of 0.5% to 2%. Most patients with an ARSA remain asymptomatic; however about to% of adult patients have compressive symptoms. A case is reported of a 64-year old female patient who had a few years of history of dysphagia and recurrent pneumonia. Angiography was performed, which demonstrated an ARSA with common origin of the right and left carotid arteries. Surgical correction was performed via right thoracotomy. The proximal aberrant artery was mobilized behind the esophagus. The distal, right subclavian artery was exposed, transected, and transposed with reimplantation into the aortic root by graft bypass.

We experienced six cases of pseudoaneurysm of the peripheral artery which occurred after stab wound or after diagnostic and operative procedures. Among 6 cases, 4 cases of pseudoaneurysm were developed in the femoral arteries, and others were the subclavian and the axillary artery. Two of 6 cases were combined with previous arterio enous fistula. Doppler imaging and angiogram were performed for the dignosis and an operation. Operative procedures were resection of the aneurysm, ligation of the involved arteries and reconstruction of the artery with the autogenous saphenous vein or the cephalic vein graft. Each operations were successfully performed without any disability.

This is a case report of an operation for the pulmonary arteriovenous fistula supplied from the systemic arteries instead of the pulmonary artery. The operation of systemic arteriovenous pulmonary fistula has formidable technical challenges due to its extensive collateral circulations. A 16 year-old female patient, diagnosed as systemic arteriovenous fistula with multiple tortuous feeding vessels and with hereditary hemorrhagic telangiectasia, was initially managed with arterial embolization before the operation. A 15${\times}$8cm sized huge vascular malformation was removed by RML and RLL bilobectomy. During the operation, we encountered annoying massive bleeding and pulmonary congestion originated in its extensive collateral circulation. The patient was discharged after conservative management without specific problem on the 15th postoperative day. For the safe operation as well as good operative result, it seemed that meticulous ligation of the multiple collateral vessels should be performed prior to that of pulmonary veins.

Heart-lung transplantation is a widely accepted treatment for Eisenmenger'syndrome. The patient is a 41-years-old male diagnosed with Eisenmenger'syndrome due to patent ductus arteriosus. The pressures were checked as follows: aorta 130/80 mean 100 mmHg, pulmonary artery 130/80 mean 109 mmHg, and right ventricle 130/20 mmHg, right atrium mean 20 mmHg. The patient needed heart-lung transplantation due to enlarged right pulmonary artery (diameter 7.5 cm). The donor was a 24 years-old male diagnosed as brain death due to subdural hematoma. Ligation of patent ductus arteriosus was performed under the cardiopulmonary bypass followed by heart-lung transplantation. Patient was extubated on postoperative day one, transferred to the general ward on day 3, and was discharged on postoperative day 33. Cardiac and lung biopsy was performed on postoperative day 41 with no signs of rejection.

We report a case of a 46-year-old man with end-stage renal failure who developed a giant aneurysm after a brachiocephalic arteriovenous shunt. The patient had complaints of pulsating pain and swelling of his left upper extremity The patient had abandoned use of the arteriovenous shunt and had a second arteriovenous shunt procedure over his right extremity. The giant venous aneurysm was removed just distal to his anastomosis. The patient's postoperative course was uneventful.

Atrial natriuretic peptide (ANP) is associated with the variety of disorders of myocardial function. The effect, however, of myocardial infarction (MI) on ANP has not been fully described. Thus, this study investigated the effect of experimental MI, induced by left coronary artery ligation, on ANP secretion. Male Sprague-Dawley rats aged 60 d underwent ligation of the left anterior descending coronary artery to induce MI and were compared with a group that underwent a sham operation. Rats of sham operation had a similar procedure without having the suture tightened around the coronary artery. Animals were sacrificed at 1, 3, 6, 12, and 18 h or 1, 3, 5, 7, 14, and 30 d after the procedure. MI size was assessed by planimetry and perimetry, and plasma ANP levels were determined by radioimmunoassay. Mean infarct size was 39.6-44.5% of the left ventricle after coronary occlusion in experimental groups. No significant differences were observed in infarct size among groups. In contrast, the concentration of plasma ANP was significantly higher at 1, 3, 6, 12, 18, and 24 h after left coronary artery ligation than in sham animals. This parameter, however, did not differ significantly at 3, 5, 7, 14, and 30 d after ligation compared with sham-ligated controls. These results demonstrate that plasma ANP levels are markedly increased in the early phase of MI in the male rat and can be a useful biomarker for diagnosis in acute MI.

Recently we operated on two cases of PDA in premature infant. In both cases, indomethacin therapy had failed to close the PDA. The extremely small baby(body weight 540gm) died 28hrs postoperatively by unexpe ted intrathoracic bleeding probably due to coagulopathy related to septic condition and thrombocytopenia. The clinical course of the second case(body weight 1395gm) was complicated by ileal perforation sec- ondary to necrotizing enterocolitis. The baby underwent segmental resection of ileum with ileostomy on the 8th hospital day. On the 34th hospital day surgical closure of the PDA was done and the ile'ostomy was repaired simultaneously. Ventilator weaning was possible on the postoperative 6th day. The baby discharged on the postoperative 33th day with the body weight of 2050gm.
