We report the case of a 37-year-old man who suffered from biventricular failure due to left isomerism, inferior vena cava interruption with azygos vein continuation, bilateral superior vena cava, double outlet of right ventricle, complete atrioventricular septal defect, pulmonary stenosis, and isolated dextrocardia. Heart transplantation in patients with systemic venous anomalies often requires the correction and reconstruction of the upper & lower venous drainage. We present a case of heart transplantation in a patient with left isomerism, highlighting technical modifications to the procedure, including the unifocalization of the caval veins and reconstruction with patch augmentation.

Thromboembolic complications (TECs) are clinically important sequelae of nephrotic syndrome (NS). The incidence of TECs in children is approximately 2%-5%. The veins are the most commonly affected sites, particularly the deep veins in the legs, the inferior vena cava, the superior vena cava, and the renal veins. Arterial thrombosis, which is less common, typically occurs in the cerebral, pulmonary, and femoral arteries, and is associated with the use of steroids and diuretics. Popliteal artery thrombosis in children has been described in cases of traumatic dissection, osteochondroma, Mycoplasma pneumoniae infection, and fibromuscular dysplasia. We report of a 33-month-old girl with bilateral iliac and popliteal arterial thrombosis associated with steroid-resistant NS due to focal segmental glomerulosclerosis. Her treatment involved thrombectomy and intravenous heparinization, followed by oral warfarin for 8 months. Herein, we report a rare case of spontaneous iliac and popliteal arterial thrombosis in a young child with NS.

A one year old spayed female Bichon Frise dog presented with gait abnormalities and seizure. Serum biochemical results showed elevated levels of alkaline phosphatase, alanine aminotransferase, and ammonia. Serum bile acid level was also increased to be over 30 μmol/L on preprandial. Urinalysis identified the presence of ammonium urate crystal. Abdominal ultrasonography and CT revealed aberrant, tortuous, and multiple small vessels connected to the caudal vena cava between left kidney and caudal vena cava. Macroscopic specific findings associated with extrahepatic congenital portosystemic shunts (PSS) or other liver diseases were not identified. Liver biopsy was performed. Histopathologic evaluation revealed hepatic lobular hypoplasia with portal arterial duplication and vascular shunts. Based on these finding, this case was diagnosed as multiple acquired PSS secondary to hepatic microvascular dysplasia (HMD) and hepatic encephalopathy. A liver biopsy is recommended to differentiate HMD from other liver diseases and to confirm HMD when a young dog has multiple acquired PSS.

Scimitar syndrome is a rare congenital anomaly that is characterized by hypoplasia of the right lung and the right pulmonary artery with anomalous pulmonary venous drainage to the inferior vena cava. The scimitar vein is usually visible on chest radiographs, but may be obscured by the heart. It is essential for surgical correction to establish the point of drainage of the anomalous vein and associated anomalies. There are recent reports of familial total anomalous pulmonary venous return suggesting heritable forms of this anomaly. Although genetic factors are believed to have important roles in congenital heart disease, few genes involved in heart development have been located. We report a case of familial chromosome 9 inversion with Scimitar syndrome in an offspring who presented with dextrocardia. Evaluation with magnetic resonance cineangiograph imaging demonstrated an anomalous pulmonary vein draining into the inferior vena cava above the diaphragm and hypoplasia of the right lung and the right pulmonary artery. Chromsome analysis showed pericentric inversion of chromosome 9, inv 9 (p13, q21), in the patient and his mother as well. A brief review of the related literature is also included.

Purpose: The purpose of this study was to report the treatment results of patients with traumatic cardiac tamponade after the opening of Jeju Regional Trauma Center. Methods: We analyzed the treatment outcomes of patients with traumatic cardiac tamponade who were treated at Jeju Regional Trauma Center from January 2018 to August 2022. Results: Seven patients with traumatic cardiac tamponade were treated. The male to female ratio was 1.33:1 (four male and three female patients) and the average age was 60.3±7.2 years. The mechanism of injury was blunt trauma in six cases and penetrating injury in one case. Upon arrival at the emergency department, pericardiostomy was performed in four cases, and an emergency operation was performed in six cases. Pericardiostomy alone was performed in one patient, who had cardiac tamponade due to extrapericardial suprahepatic inferior vena cava rupture. The causes of cardiac tamponade were right atrium appendage rupture in one case, right ventricle rupture in one case, inferior vena cava rupture in two cases, right atrium and left atrium rupture in one case, both atria and left ventricle rupture in one case, and intercostal artery rupture in one case. In three cases, intraoperative cardiopulmonary bypass was required. Two of the seven patients died (mortality rate, 28.5%). Conclusions: Relatively favorable treatment results were observed for traumatic cardiac tamponade patients after Jeju Regional Trauma Center was established.

Epithelioid hemangioendothelioma (EHE) is a low-grade malignant vascular neoplasm that can occur anywhere in the body. EHE has a low annual incidence (0.38/10⁶) and prevalence (< 1/10⁶), and primary mediastinal EHE is exceedingly rare. We report a case of EHE in a 53-year-old female which manifested as an incidentally discovered mass in the right paratracheal region. In this report, authors describe the pathological and radiological findings of primary mediastinal EHE invading the superior vena cava in the right paratracheal area.

Cholangiocarcinoma is a heterogeneous group of aggressive tumors that correspond to the second most common primary liver tumor. They can be classified according to their anatomical position concerning the biliary tree, and each subtype demonstrates different behavior and treatment. A 38-year-old male patient presenting solely right lumbar pain was diagnosed with a 7 cm hepatic tumor involving segments I, Iva, and VIII associated with involvement of the hepatic veins. He underwent a bloc resection of hepatic segments I, II, III, IV, partial V, partial VII, and VIII; right, middle, and left hepatic veins; and inferior vena cava segment, with perfusion of the remaining liver in situ with a preservation solution. As the patient had a large accessory inferior right hepatic vein draining the remaining liver, no reimplantation of hepatic veins was necessary. He remained clinically stable in outpatient follow-up, with excellent performance status-current survival of 2 years 6 months after surgical treatment.

From June 1989 to July 1992, we used centrifugal Biomedicus pump[CBP] in 20 patients In 9 cases, CBP was used as ventricular assistance after heart surgery for those who could not be weaned off bypass even with intra-aortic balloon counter-pulsation and with maximal inotropic support In 8 patients, CBP was used as partial left heart bypass during repair of aortic aneurysms or congenital aortic anomalies. And in 3 patients, CBP was used as vena caval bypass during resection of renal cell carcinoma with tumor extension into the inferior vena cava. In 2 of 9 patients with ventricular assistance, they were weaned off the device successfully after 16 hours and 7 days respectively. But the patients died of intracranial hemorrhage and sepsis, 7 and 29 days after weaning from cardiac support, respectively. In all the patients who underwent aortic of vena caval surgery using CBP as shunt, there were no complications such as postoperative bleeding necessitating reoperation, renal failure or neurologic sequelae. In conclusion, the centrifugal type of ventricular assistance may be potentially life saving treatment modality in patients with severe postoperative low cardiac output syndrome. The CBP can be safely employed for resection of renal cell carcinoma with vena caval tumor extension and for repair of aortic aneurysms.

A 34-year-old man was admitted to the hospital because of ascites, abdominal fullness. computed tomography and cavography revealed inferior vena cavil occlusion just above the hepatic vein and diagnosed as Budd-Chiari syndrome. conservative medical therapy failed to control the symptoms produced from both portal hypertension and versa caval stasis. Therefore, under extracorporeal circulation with moderate hypothermia and normal cardiac contraction, membranoto y and inferior vena casa venoplasty with Gore-tex (10mm) was performed. Postoperatively, physical examination revealed oral ulceration, subcutaneous thrombophlebitis, folliculitic lesions. uveitis And increased reactivity of the skin to needle punctures. 10 month later, superior vena ciiva obstruction symptom was found. Hehcet's disease was diagnosed.
