A case of unilateral pulmonary vein atresia with absent right superior vena cava in 9 years-old boy is described with a discussion. Clinical findings were similar to other reports and consisted of hemoptysis, dyspnea and anemia. A chest X-rary revealed irregular vascular marking on left lung fiedld and increased interstitial marking on right upper lung field. The diagnosis could be confirmed with radionuclide perfusion study, MRI scan of heart and great vessels and angiography which demonstrated a small right pulmonary artery, pruned its peipheral branches, stasis of contrast material and nonvisualization of draining righ pulmonary veins. Pneumonectomy, patch angioplasty of diaphargm excision will be necessary.

We report a case of Mycobacterium(M.) fortuitum infection in a 65-year-old female who presented with erythematous to purplish colored tender nodules and plaques with curst and purulent discharge on both upper and lower extremities along the sites of acupuncture. The culture of surgically excised specimen in 3% Ogawa media yielded slightly yellowish colored colonies within 2 days. Several tests for identification of the species were performed and growth on 5% NaCl, negative niacin test, positive results in nitrate reduction, catalase, urease and iron uptake tests were noted. Excision of the lesions followed by administration of minocycline and ciprofloxacin showed no sign of relapse to data a year after treatment.

PURPOSE: This study was perfomed to evaluate the success rate and complications of transcatheter closure of patent ductus arteriosus with the Rashkind PDA Occluder System (USCI). METHODS: Between February 1993 and January 1996, 24 patients (6 men and 18 women, median age 4 years, range 10 months to 51 years) were treated with the Rashkind PDA Occluder System for occlusion of patent ductus arteriosus at Dong-A University Hospital. The rate of presence of residual shunt and complications associated with the ductus occlusions in these patients were investigated. RESULTS: At pre-occlusion cardiac catheterization, mean Qp/Qs was 1.49+/-0.48 and mean pulmonary artery pressure was 18.1+/-4.93mmHg. The narrowest diameters of ductus ranged from 1.2mm to 6mm (mean 2.8+/-1.3mm). The most frequently encountered ductal shape was Krichenko type A (16 patients, 66.6%). Three patients required dilatation of ductus with 3mm balloon catheter to cross with 8Fr long sheath. Seventeen 12mm and seven 17mm devices were successfully placed in twenty-four patients. Mean pulse pressure was decreased from 45.5+/-7.11mmHg to 38.8+/-8.98mmHg (p<0.05). After occlusion, the continuous murmurs were disappeared from all but one. From the immediate (20 minute) postocclusion aortogram, 12 of 24 patients (50%) had evidence of residual left to right shunt through the ductus. Four of these 24 patients (17%) demonstrated residual shunt by echocardiogram which performed within 2 weeks after the procedure. Of 20 patients with 3 patients who had residual shunt at previous study, having returned for follow up echocardiogram at 6 months after occlusion, only one (5%) had residual shunt. There were no significant differences in incidence of residual shunt according to size of devices or ductal shape. In 2 patients, Doppler study revealed mild pressure gradient at origin of left pulmonary artery. CONCLUSIONS: In selective candidates, transcatheter closure of the patent ductus arteriosus using the Rashkind PDA Occluder System is a safe and effective method in the nonsurgical management of patent ductus arteriosus.

For some cyanotic children with deficient pulmonary blood flow, the Blalock-Taussig shunt is a life-saving or temporizing form of palhation. Extensive experience has been gathered, and mortality and morbidity as well as the incidence of shunt stenosis and thrombosis have significantly decreased. However, even nowadays, the most frequently encountered complication excluding mortality in early postoperative course is occlusion of the shunt. We experienced a case of Blalock-Taussig shunt occlusion with thrombus. We diagnosed him as ventricular septal defect with pulmonary atresia by echocardiography and performed a right classic Blalock-Taussig shunt at 7th day of age, Oxygen saturation was gradually decreased since the 6th day postoperative. He was diagnosed as thrombosis of shunt at 12th day postoperative by cardiac angiography, and then was treated with a local low-dose urokinase infusion(1,000U/kg/hr) through Cobra catheter(Cook. In. Co.). After 21 hours, thrombolysis of shunts was comfirmed. We stopped the urokinase and medicated low-dose aspirin(5mg/kg/day). After the eighth day, shunt flow by echocardiography was patent.

PURPOSE: We conducted this study to evaluate the efficacy of Doppler study by examining obstruction at the site of anastomosis in patients with total anomalous pulmonary venous return(TAPVR). METHODS: Retrograde analysis of the postoperative echocardiography results was done in 14 patients with simple TAPVR, who were operated at Dong-A University Hospital from January 1993 to July 1998. The peak systolic velocities, peak diastolic velocities and flow patterns of the 14 patients were compared with those of 9 control cases. Among the 14 patients, 2 cases showed evidence of obstruction at the anastomosis site. RESULTS: Pulmonary venous flow patterns of normal infants were biphasic, varying with the cardiac cycle. The peak velocities during systole and diastole were 40 to 60cm/sec(mean 51+/-9cm/sec) and 45 to 78cm/sec(mean 59+/-9cm/sec), respectively. The flow patterns of patients without postoperative stenosis were also biphasic. The peak velocities during systole and diastole was 38 to 115cm/sec(mean 71+/-27cm/sec) and 55 to 140cm/sec(mean 111+/-28cm/sec), respectively. The diastole peak velocity was significantly higher than normal(P=0.0002). The flow patterns of patients with postoperative stenosis was continuous, non-phasic or increased peak velocity even though it was phasic. CONCLUSION: Postoperative Doppler echocardiographic evaluation of pulmonary venous return in patients with TAPVR is useful in examining obstruction at the site of anastomosis. But a study on the Doppler echocardiographic normal range of postoperative patients will be needed.
