  • Background: There is evidence that platelet is activated in chronic obstructive pulmonary disease and activated platelet with injured endothelium contribute to the pathogenesis of pulmonary hypertension, prognostic factor of chronic obstructive pulmonary disease. So, we have investigated platelet function further in chronic obstructive pulmonary disease and effect of platelet activation on pulmonary hypertension. Method: We studied platelet aggregation ratio and alpha-granule products such as platelet factor 4(PF4) and beta-thromboglobulin (${\beta}$-TG) in control subjects and COPD without and with pulmonary hypertension subjects. Result: 1) The platelet aggregation ratio (PAR) was $0.99{\pm}0.04$ in control subjects, $0.98{\pm}0.05$ in COPD without pulmonary hypertension subjects and $0.89{\pm}0.08$ in COPD with pulmonary hypertension subjects. The platelet aggregation ratio of COPD subjects was tend to decrease than that of control subjects and the ratio of COPD with pulmonary hypertension subjects was significantly lower than that of control subjects. 2) The platelet factor 4 (PF4, IU/ml) was $4.7{\pm}1.2$ in control subjects, $18.6{\pm}4.9$ in COPD without pulmonary hypertension subjects and $57.2{\pm}12.7$ in COPD with pulmonary hypertension subjects. The level of COPD subjects was significantly higher than that of control subjects and the level of COPD with pulmonary hypertension subjects was significantly higher than that of COPD without pulmonary hypertension subjects. 3) The beta-thromboglobulin (${\beta}$-TG, IU/ml) was $34.4{\pm}5.8$ in control subjects, $80.4{\pm}18.1$ in COPD without pulmonary hypertension subjects and $93.0{\pm}14.0$ in COPD with pulmonary hypertension subjects. The level of COPD subjects was significantly higher than that of conrtrol subjects and the level of COPD with pulmonary hypertension subjects was tend to increase than that of COPD without pulmonary hypertension subjects. 4) There was no correlation between the clinical parameters and PAR, PF4 and ${\beta}$-TG but there was significant correlation among PAR, PF4 and ${\beta}$-TG. Conclusion: The platelet is activated in chronic obstructive pulmonary disease and the platelet of COPD with pulmonary hypertension is tend to be activated more than that of COPD without pulmonary hypertension. So, activated platelet may involve in the pathogenesis and maintenance of pulmonary hypertension in COPD subjects and modulation of platelet activity that might reduce pulmonary hypertension needs to be determined.

  • Primary sarcomas of the pulmonary arteries are and the clinical presentation closely resembles several more common conditions, Therefore they are seldomly diagnosed preoperatively without a pathologic esxamination of sufficient surgical specimen. Treatment of these tumors remains primarily surgical as possible and the role of the adjuvant chemotherapy and radiotherapy is not yet evident We report a case of primary sarcoma of pulmonary artery clinically suspected of carcinoid partially involving the pulmonary parechyme and the bronchus mainly in the left main pulmonary artery and the vein with left intrapericardial pneumonectomy.

  • Pulmonary atresia with VSD is uncommon congenital anomaly with high mortality in neonatal period. Recently we experienced surgical correction of 2 cases of pulmonary atresia with VSD. The first case was 7-year old female patient and diagnosed as pulmonary atresia with VSD combined PDA. So, total correction was undertaken which consisted of PDA ligation, patch repair of VSD, transannular enlargement of RVOT with woven Dacron vascular graft, and closure of PFO. Postoperative systemic Rt. ventricular and radial artery pressure ratio was 0.44 and her postoperative course was uneventful. The second case was 6-year old male patient diagnosed as pulmonary atresia with VSD and large systemic-pulmonary collateral arteries. There were two large systemic-pulmonary collaterals, one was simply controlled by ligation, but the other was considered to supply Rt. upper lung. So end to side anastomosis was performed to the RVOT patch. Postoperative systolic Rt. ventricular and radial artery pressure ratio was 0.54. During the follow up period he showed clinical picture of Rt. heart failure, which is relatively well controlled with anticongestive therapy.

  • We experienced a case of anomalous origin of right pulmonary artery from the ascending aorta associated with pulmonary atresia, ventricular septal defect, absence of left pulmonary artery afld multiple major aortopulmonary collateral artery (MAPCA). At ten month of age, left pulmonary artery creation with unifocalization and right pulmonary artery banding were performed as the Urst stage, followed by coil embolization of right MAPCA 1 month later, and 1 year later, the total correction was done. After total repair, the patient showed good postoperative course and excellent angiographic and hemodynamic results at 1 year follow-up study.

  • Pulmonary arteriovenous fistula can be either congenital or acquired. The vast majority are congenital, and about 60% have been associated with hereditary hemorrhagic telangiectasia [Rendu-Osler-Weber disease . Secondary or acquired pulmonary arteriovenous fistula occurs with trauma, schistosomiasis, long-standing hepatic cirrhosis, metastatic carcinoma, and actinomycosis. Pulmonary hemorrhage secondary to acquired pulmonary arteriovenous fistula is a rare event associated with mortality. We have experienced 64 year-old female patient with the hemoptysis secondary to acquired pulmonary arteriovenous fistula due to the infection of pulmonary parasite. The chest PA and CT scan was showed calcified nodule to the distal portion of lateral segmental bronchus of RML. The bronchial angiogram was demonstrated slightly hypertrophied bronchial artery supplying RML bronchus and the presence of hypervascularization around the calcified nodule, rapid A-V shunting is noted by fluoroscopy. The patient was successfully treated by the right middle lobectomy.

  • IgA nephropathy usually presents as asymptomatic microscopic hematuria or proteinuria or episodic gross hematuria after upper respiratory infection. It is an uncommon cause of end-stage renal failure in childhood. Pulmonary hemorrhage associated with IgA nephropathy is an unusual life-threatening manifestation in pediatric patients and is usually treated with aggressive immunosuppression. Pulmonary hemorrhage and renal failure usually occur concurrently, and the pulmonary manifestation is believed to be caused by the same immune process. We present the case of a 14-year-old patient with IgA nephropathy who had already progressed to end-stage renal failure in spite of immunosuppression and presented with pulmonary hemorrhage during oral prednisone treatment. His lung disease was comparable to diffuse alveolar hemorrhage and was successfully treated with plasmapheresis followed by oral prednisone. This case suggests that pulmonary hemorrhage may develop independently of renal manifestation, and that plasmapheresis should be considered as adjunctive therapy to immunosuppressive medication for treating IgA nephropathy with pulmonary hemorrhage.

  • A case of malignant fibrous histiocytoma [MFH] of left pulmonary artery was reported in the 27 year-old male. He was admitted because of hemoptysis for several times. Chest x-ray revealed nodular lesions in left hilar area and left upper lobe. A left thoracotomy was performed followed left upper lobectomy. The main tumor was originated from the pulmonary arterial bifurcation and proximal portion of the left pulmonary artery. By light microscopy, there were many pleomorphic giant cells, which displayed the storiform pattern. And in those area, dilated or compressed vascular channels were involved by tumor cells, suggesting origin of This tumor. Pulmonary artery angiography and chest CT revealed this tumor was originated from pulmonary artery. It would be the first reported primary malignant fibrous histiocytoma of the pulmonary artery in our country. Postoperative prognosis was uneventful, but recently he was suffered from dyspnea, that was noticed by OVD follow-up for 1 month, probably the heart failure sign due to pulmonary arterial flow obstruction.

  • Pulmonary thromboembolism originated mostly from the venous thrombus, especially deep vein thrombosis in the lower extremities, which migrated upward and lodged the pulmonary vasculatures, Massive pulmonary thromboembolism usually leads to in \ulcornerhospital mortality if the patient was not treated properly. Under the cardiopulmonary bypass, a 49-year old man was treated successfully by emergent pulmonary embolectomy of pulmonary thromboembolism, which originated from the deep vein thrombosis in the right leg. Ligation or filtering device insertion of the inferior vena cava was not performed. The patient’s postoperative course was uneventful and discharged on postoperative 15th day He continued to receive oral anticoagulation with aspirin and persantin, which had been started on the third postoperative day. And he was well till recent days through the outpatient follow-up. The clinical courses of this patient are described, and massive pulmonary embolism and its management are discussed.

  • Intralobar pulmonary sequestration is a rare congenital malformation characterized by a cystic portion of the lung that derives its arterial blood supply through aberrant vessel directly of systemic circulation. Two forms of pulmonary sequestration occur; intralobar sequestration is usually contained within the visceral pleura of a pulmonary lobe and its venous drainage to the pulmonary venous system. We presented on case of intralobar pulmonary sequestration with A-V fistula. The patient was 8 years old male and chief complaints are mild fever and exertional dyspnea. Aortogram revealed an aberrant artery originated from thoracic aorta just above the diaphragm and its vessel directly communicated pulmonary vein in sequestrated segment. At time of operation, sequestrated lobe measuring 6x5x5cm, well demarcated at the lower lobe was noted. Aberrant, measuring 1.0cm in diameter and 1cm in length and directly connected pulmonary vein. After division and ligation of the aberrant artery, only excision of sequestrated lobe was performed and complication is not during postoperative course.
