The isolated coronary ostial stenosis is rare and a critical lesion which requires urgent surgical intervention. Recently direct angioplasty is assumed as a preferable approach to conventional bypass grafting. From Mar. 1990 to Aug. 1993, six patients underwent direct angioplasty in Sejong Heart Institute. The mean age of 6 patients was 48 years [range 37 to 63 and they consisted with 5 females and one male. All had severe angina [class III or IV of short duration [mean 5.3 months and a low incidence of risk factors. Despite the crucial location of the lesion, most patients had well preserved left ventricular function and normal wall motion. We performed direct angioplasty with autologous pericardium via anterior approach except one patient who underwent direct angioplasty and CABG. One patient died 4 hours after angioplasty probably due to acute coronary dissection. The survived 5 patients maintain normal life without symptoms during 26.2 months follow up [range 5 to 47 months .Our preliminary results suggest that angioplasty of isolated coronary ostial stenosis in highly selected patient can be carried out with good results and relatively low operative risks.

Author studied the pathogenesis of Sino-bronchiectasis with review of clincal and pathological findings of resected lungs in 24 eases of bronchiectasis,and the results were as follows: 1. Of the 24 eases of bronchiectasis, Sino-bronchiectasis were found in 11 cases and these cases most commonly, developed in first and second decade of life. In a majority of these cases,the main symptoms were the signs of wet bronchiectasis. 2. The typical roentgenograrn changes of plain chest x rays were increase in size and loss of definition of the markings and bronchographically revealed the cylindrical or tubular form in majority of these cases. 3. Pathologically Sino-bronchiectasis involved specific segmental areas of the lungs such as left basal and S4+5 segments and revealed commonly tubular dilatation. The most common findings of bronchial wall of dilated bronchus were the inflammatory cellular infiltration and cylindrical hyperplasia of mucus epithelial layers. 4. It was suspected that there were some causal relations in pathogenesis between chronic sinusitis and bronchiectasis.

We have experienced one case of hemoptysis which developed from both upper lung fields due to pulmonary aspergilloma combined with pulmonary tuberculosis. A 48 year old female patient was admitted with 10 years history of recurrent hemoptysis. Chest X-ray film revealed moderately advanced active pulmonary tuberculosis lesion on both upper lung fields, and cresentic radiolucent space between cavity wall and round radiopaque lesion on left upper lung field. Bronchial arteriogram showed hypervascularity and extravasation of contrast media in the right lung and it was treated by bronchial artery embolization. Hemoptysis recurred 7 months after embolization and repeat examination revealed greatly increased bronchial vasculature in the left upper lobe and therefore underwent left upper lobectomy. The pathologic result was compatible with aspergillosis, and the postoperative recovery was uneventful.

A case of complete interruption of aortic arch with aortopulmonary window, patent ductus arteriosus, and aberrantly originated right subclavian artery from proximal descending aorta, in a four year old boy is reported in detail. This is the only reported case in Korea, who has had a successful one-stage total anatomical correction of this combination of defects. Under deep hypothermia and total circulatory arrest, aortic continuity was established using patent ductus arteriosus and anterior wall of pulmonary artery, which was anastomosed obliquely to anteromedial side of ascending aorta. Aortopulmonary window was closed using Impra patch via pulmonary arteriotomy. Then pulmonary arteriotomy was reconstructed primarily except at the junction of right pulmonary artery and main pulmonary artery, where a small piece of pericardium was used to close the defect to prevent kinking and narrowing of right pulmonary artery. Postoperative cardiac catheterization demonstrated a good reconstruction.

Though esophageal cancer was not a common disease, early metastasis and direct extension to adjacent organ were important on the treatment of disease. Therefore, palliative operation was often useful in advanced esophageal cancer. Between June 1985 through July 1985, we treated three cases of inoperable esophageal cancer with Celestin`s endo-esophageal tube by esophageal intubation. Three operations were done under general anesthesia. Celestin`s tube were inserted via oral cavity and additional traction on stomach were applied. After complete insertion of tube was done, the distal end of Celestin`s tube was modified in length. Also stay suture was applied between tube and stomach wall was applied. Postoperative esophagogram revealed good esophageal patency through Celestin`s tube. Clinically, swallowing difficulty was much improved after operation.

Interruption of the aortic arch may be defined as discontinuity of the aortic arch in which either an aortic vessel or a patent ductus arteriosus supplies the descending aorta. This anomaly is a rare congenital malformation that usually occurs with severe associated intracardiac congenital anomalies, such as ventricular septal defect, patent foramen ovale and abnormal arrangement of the brachiocephalic arteries. Rarely, transposition of the great vessel, truncus arteriosus are coexistent. We experienced a case of the interrupted aortic arch [Type A] associated with VSD, PDA and patent foramen ovale in a 16 years old female. One stage total correction was done under profound hypothermia with total circulatory arrest. Aortic continuity was established using patent ductus arteriosus with anterior wall of main pulmonary artery, which was anastomosed obliquely to anteromedial side of the ascending aorta. Ventricular septal defect was closed using Dacron patch and patent foramen ovale was closed directly. Postoperative course was uneventful, except mild hoarseness.

A 50-year-old male patient was admitted due to right ventricular & aortic foreign bodies with ascending aortic pseudoaneurysm. The patient had a history of Kirschner wire fixation of right sternoclavicular joint 3 months ago. Under cardiopulmonary bypass, two K-wires were removed and injured pulmonary valve leaflet and aortic wall were repaired successfully The postoperative course was uneventful and the patient was discharged on the 14th postoperative day.

in general rapid and complete resolution of pulmonary emboli, even massive, is the natural history. However, rarely, the emboli do not resolve but rather became fibrotic organization and densely adherent to the arterial wall, therefore, may lead to significant clinical disability. In patients with chronic pulmonary embolism, medical management usually has little effect and only surgical treatment can offer improvement. The case was 30-year-old man who had admission to the Hanyang University Hospital due to fall-down from 11th floor 407 days before operation and then transferred to our department for surgical management under the diagnosis of chronic pulmonary embolism, Pulmonary angiogram demonstrated multifocal thromboembolism with infarction and lung scans showed no improvement in spite of anticoagulant and thrombolytic therapy. At median sternotomy for pulmonary artery thromboembolectomy, the well organized and multiple septic emboli could be removed by gallstone forceps. But reoperation of left upper lobectomy was performed because of the repeated hemoptysis and suspicious pulmonary arterio-bronchial fistula 19 days postoperatively. Despite of ventilatory support and drug treatment, the patient died due to right heart failure associated with cor pulmonale 27 days after first operation. Discussion of the operative and perioperative problems are offered.

Direct anterior approach for lesions located anterior to the thecal sac is definitely superior to lateral or posterior approach in many respects. However, various anatomical obstacles and technical difficulties often hinder direct anterior approach. Thanks to ripe experience of retroperitoneal approach to the lumbar spine for anterior lumbar interbody fusion and total disc replacement, the authors could perform lumbar corpectomy and reconstruction by using midline retroperitoneal approach recently. During this approach, we repaired anterior longitudinal ligament also to reduce the risk of graft extrusion and to prevent erosion of vascular wall due to direct contact between metallic hardware, which was used for reconstruction of vertebral body, and major vessels.

There are three types of papillary muscle of the left ventricle[finger, tethered and mixed type] according to the morphology of the attachment to the ventricular wall. Especially finger type of the papillary muscle is more vulnerable to the injury than tethered or mixed type, because their blood supply is dependent upon the central artery whose diameter is less than 1mm and the papillary muscle itself is the end organ of the heart anatomically. There are several causes of papillary muscle rupture but few cases have been reported. Recently we have experienced 3 cases of papillary muscle rupture of the left ventricle with successful mitral valve replacement and the causes are postmyocardial infarction, percutaneous mitral valvulotomy and non-penetrating chest trauma. The common finding is the morphology of papillary muscle, that is the finger type and their rupture type is the complete type.
