Pulmonic autograft replacement of the aortic valve(Ross procedure) has been to have potential for growth in children, no complication of antiocagulation, and enhanced durability. Therefore, Ross operation is indicated in the young, in patients with an active life style, and when anticoagulation is contraindicated. However, late autograft valve has occurrd more frequently in patients with significant size discrepancy between the pulmonay valve annulus and the aortic valve annulus. In order to resolve this problem, we performed aortic annuloplasty with Duran ring for more accurate and strong reinforcement. We report a case using the Duran ring as a method of aortic annuloplasty during Ross procedure.

In small children with left ventricular outflow tract obstruction, a few methods of surgical treatment could be considrred. The pulmonary autogrart provides a promising options for aortic valve replacement as part of the aortoventriculoplasty procedure in children. We report a successfully treated congenital aortic stcnoinsufricicncy with severe left ventricular dysfunction in an early infant with the aortoventriculoplasty using thc pulmonary autograft (the Ross-Konno procedure).

Between July, 1990 and July, 1992, 6 male patients of truncus arteriosus, whose age ranged from 2 months to 18 months, underwent total surgical correction without a extracardiac conduit. Their anatomic types were type I in 3, type II in 2 and III, in one by the Collett-Edwards classification. Surgical techniques were similar to the first description by Lecompte except for the fact that distal pulmonary arterial stumps were approximated to ventriculotomy site without Lecompte maneuver in all cases. Also in all cases, mon-ocusps were placed using glutaraldehyde fixed autologous pericardial patch directly in right ventricular outflow tract. Three patients died postoperatively and the causes of death were myocardial failure, pulmonary hypertensive crisis and pulmonary complication due to progressive pulmonary vascualr obstructive disease respectively. The three survivors have been followed up for 6~10 months with good functional results.

Vocal fold scar disrupts structure of lamina propria and causes significant change in vocal fold tissue biomechanics, resulting in a range of voice problems that often significantly compromise patient quality of life. Although several therapeutic management have been offered in an attempt to improve vocal fold scar, the ideal treatment has not yet been found. Recently, several tissue engineering technique for vocal fold scar using growth factors, several cells, and scaffolds have been described in tissue culture and animal models. Several growth factors such as hepatocyte growth factor, basic fibroblast growth factor, and transforming growth factor beta 3 for therapy and prevention of vocal fold scar have been studied. Cell types to regenerate vocal folds in scarring tissue have been introduced autologous or scarred vocal fold fibroblast and adult mesenchymal stem cells. Decellularized organ matrix and several hyaluronic acid materials have used as scaffolds for vocal fold scar.

Membranous obstruction of the inferior vena cava[IVC] is a rare congenital anomaly that may present clinical features of Budd-Chiari syndrome caused by chronic obstruction of hepatic drain. We have experienced a case of IVC obstruction caused by hour-glass constriction and membrane in its center. Operative correction was accomplished using profound hypothermia [20%] and total circulatory arrest of 26 minutes. This technique permitted resection of membrane with direct vision and removal of thrombus of IVC and hepatic vein. After then constricted IVC was repaired with autologous pericardial patch. Total circulatory arrest was used intermittently for good visual field. Postoperative course was smooth and postoperative angiography showed unobstructed flow through the IVC in spite of slight constriction of cavoatrial junction and nearly complete disappearance of collateral vessels.

We have experienced a patient, 16 year-old male, with ventricular septal defect with tricuspid recur- gitation due to blunt chest trauma. He suffered from congestive heart failure after the trauma. Echocardiogram and cardiac catheterization revealed left to right shunt at the ventricular level (muscu- far portion of interventricular septum) and tricuspid regurgitation. At the time of the operation, marked systolic thrill was palpable over the rlght ventricle near the apex and a chorda tendina was seen sharply ruptured just near the medial papillary muscle. We repaired the ventricular septal defect with a Dacron patch and chordal reconstruction with autologous pericardium. The postoperative course was uneventful and the patient was discharged in good condition.

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.

While popliteal artery aneurysm is the most common form of peripheral artery aneurysm, it is a rare condition in the general population. Furthermore, a giant popliteal artery aneurysm has not previously been reported in Korea. A 67-year-old male presented with left thigh pain that had begun 4 months earlier and was aggravated when in a sitting position. We found a giant aneurysm on the left popliteal artery and performed a bypass from the common femoral artery to the distal popliteal artery below the knee, using the autologous greater saphenous vein, and excluded the aneurysm at the sites of anastomoses.

PHILOS plate fixation in osteoporotic proximal humerus fracture of old age is well-known for high complication rate, especially metal failure, providing various augmentation techniques, such as calcium phosphate cement, allogenous or autologous bone graft. We report a case of polymethyl methacrylate augmentation to provide appropriate reduction with a significant mechanical support. This can be a treatment option for displaced unstable osteoporotic proximal humerus fracture with marked bony defect.
