We report the case of a 64-year-old man with superior vena cava (SVC) syndrome due to tumor thrombus from recurrent hepatocellular carcinoma (HCC). He presented with new onset of facial swelling for 10 days. HCC was detected ten years ago. He has undergone repeated transcatheter arterial embolization (TAE) and chemotherapy. Chest computed tomography (CT) demonstrated tumor thrombus in the SVC extending to right atrium. He underwent whole body F-18 fluorodeoxyglucose(FDG) positron emission tomography/computed tomography (PET/CT) scanning for assessing the effect of TAE in HCC. F-18 FDG PET/CT showed increased uptake in the residual liver mass indicating viable tumor. There was another intense F-18 FDG accumulation in SUV extending to right atrium to suggest tumor thrombus. This case illustrates that F-18 FDG PET/CT is useful to identification of distant metastases as well as assessment of response to therapy in long-term survival HCC patients.

We operated on a 41-year-old man using venous bypass shunt for superior vena cava (SVC) syndrome caused by mediastinal fibrosis. The patient had substantially high venous pressure and high risk of postoperative neurologic deficits. The collateral veins were deemed to be interrupted during the surgical reconstruction of SVC. Treatment included resection of the obstructed SVC and innominate vein and reconstruction with an autologous pericardial tube graft. During the operation, venous drainage from upper body was maintained with an extraluminal bypass shunt. The shunt was effective at prompt relief of venous hypertension, eliminating the time constraints, and preventing the postoperative complications.

The hot spot on liver scan was demonstrated by many authors in various conditions such as SVC obstruction, Budd-Chiari syndrome, liver abscess, hemangioma of liver, hepatic venoocclusive diseases, IVC obstruction, and tricuspid insufficiency. And the appearance of hot spot in SVC obstruction is due to unsual collateral circulation. But there was no report of this hots pot on liver scan in our country. We have recently observed one patient with SVC obstruction who shows well-defined area of increased radioactivity between right and left lobe of liver on liver scan using $^{99m}Tc-tin$ colloid, and demonstrated collateral circulations with RI venography using $^{99m}Tc-O_4$. The injection site of radiocolloid was left antecubital vein. This hot spot did not appear when the radiocolloid was injected into right leg vein. We report here this hot spot on liver scan in SVC obstruction with review of some liter atures.

A 36-year-old man was studied because of signs and symptoms of superior vena caval syndrome. Chest computerized tomography showed $10{\times}8{\times}6$ cm sized lobulated anterior mediastinal mass, compressing superior vena cava. Fine needle aspiration cytology revealed seminoma. There was no detectable tumor mass in the testes. We report a case of primary mediastinal seminoma presenting with superior vena caval syndrome.

A 68-year-old woman was admitted after suffering facial edema with neck vein engorgement for approximately 2 months. A chest X-ray showed a mild widening of the superior mediastinum and a luminal obliteration of the superior vena cava(SVC) was noted on a computed tomograph. Venography showed that both subclavian veins were obstructed at the level of the proximal clavicle with a nonvisualization of the SVC. The SVC, both the innominate and the left internal jugular veins were completely obstructed with extensive cord-like fibrotic changes despite the absence of mediastinal involvement. The microscopic features showed a chronic granulomatous inflammation with a fibrosis minimally invading the mediastinal fat, which is consistent with fibrosing mediastinitis.

Eaton Lambert Syndrome(ELS)is a disorder of neuromuscular transmission. The defect of neuromuscular transmission is due to decrease in the release of acetylcholine guanta from nerve terminal. This syndrome is frequently associated with bronchogenic carcinoma. The diagnosis is established by electromyography, which characteristically shows 1) low amplitude of evoked compound muscle potential to a single supramaximal stimulus on nerve, 2) significant decremental response at low rates of stimulation 3) marked incremental response at high rates of stimulation. Our patient is 52year old man with dyspnea, coughing and muscle weakness of proximal lower limbs. He has small cell lung cancer and associated with ELS, Superior venacava syndrome and has metastatic lesion on right supraclavicular lymphnode confirmed by pathology. Metastatic mass and SVC syndrome are marked improved following chemotherapy and radiotherapy, however follow up EMG finding does not improved. We are here reporting one case which considered compatible for ELS, with a few elementary reviewed literatures.

Monitoring infectious diseases for fishery species takes a key role in preventing disease emergence and spreading of cultured fishery species. This research has examined a total of 1,115 fishes of four species (leather carp, fancy carp, stone moroko, carassius auratus) at 23 farm in Jeollanamdo and Jeollabukdo in 2021 for pathogen infection. As a result of disease screening for three legally designated diseases (SVC, Spring viraemia of carp, EUS, Epizootic ulcerative syndrome, and KHVD, Koi herpesvirus disease), no infectious diseases were detected in all examined samples; cyprinid fish studied in Jeolla province would provide important information for declaring a disease-free nation or disease-free region.

Fibrosing mediastinitis is a rare disease that is characterized by the proliferation of dense fibrous tissue of the mediastinum. The pathogenesis of fibrosing mediastinitis is unknown in most cases. However, histoplasmosis, tuberculosis, autoimmune disease, radiation therapy, and other idiopathic fibroinflammatory diseases have been implicated in some cases. Most clinical features are related to an obstruction or compression of the mediastinal structure. Fibrosing mediastinitis is often progressive and occurs diffusely throughout the mediastinum. We encountered a case of fibrosing mediastinitis of a very focal lesion without evidence of mediastinal involvement. The condition was confirmed by biopsy and graft bypass surgery was performed because of SVC syndrome.

To access the result of radiation therapy for 8 years experiences, 21 patients who were treated with superior vena cava syndrome had been analysed according to dose fractionation and total dose. The results are as follows; 1. In high fractionate dose group, six of eleven patients $(54.5\%)$ exhibited relief of symptoms in 1-2 days, and additional three patients of nine $(81.7\%)$ within 34 days, while standard fractionated dose treatment is not effective to achieve initial relief of symptoms. 2. Graded response by total dose was correlated with total dose rather than dose fractionation. 3. Overall one year survival rate with superior vena cava syndrome was $9.1\%$ and mean survival was 4.2 months.

We reviewed our experiences on 33 patients who underwent a bidirectional cavopulmonary shunt[BCPS from February 1992 to July 1994. There were 19 male an 14 female patients, and their weight ranged from 4.4 to 13.3 Kg[mean weight 8.4 $\pm$2.9 Kg . The age ranged from 2 to 55 months [mean age 16.7 $\pm$15.5 months . Their diagnosis included single ventricle group in 16, unbalanced ventricles in 8 whose associated anomalies were double outlet right ventricle, transposition of great arteries and total anomalous pulmonary venous return, tricuspid atresia in 7, hypoplastic left heart syndrome in 1 who underwent a Norwood procedure and double outlet right ventricle with pulmonic stenosis and tricuspid stenosis in 1 who underwent biventricular repair. Among them 10 patients had received other palliative operation before [Norwood procedure 1, pulmonary artery banding 3, modified Blalock-Taussig shunt 6 . The BCPS operations were performed under the cardiopulmonary bypass. 16 patients underwent unilateral BCPS and 17 patients who had bilateral SVC underwent bilateral BCPS. Three patients whose associated anomalies were interruption of IVC underwent total cavopulmonary shunt. There were 5 operative deaths [mortality rate 15.1 % and 2 late deaths. The risk factor for the operation was high mean pulmonary artery pressure [p value<0.05 . The survivors showed good postoperative course and their postoperative oxygen saturation was increased significantly compared to that of preoperative status[p value<0.05 .Conclusively, BCPS operation is effective and safe palliative procedure for the many cyanotic complex congenital anomalies with decreased pulmonary blood flow especialy for the patients who have the high risk factors for Fontan operations.
