OBJECTIVE: Focused transthoracic echocardiography (FTTE) is an emerging tool in the management of critically ill patients, but the lack of adequate training models has limited the expansion of this technology. Although basic FTTE training courses have been shown to be sufficient in developing echocardiography skills, limited data exist regarding skill retention. In an effort to develop an adequate FTTE training model, we sought to determine the degree of skill retention after FTTE training...

BACKGROUND: Patients with tumors invading major veins may require combined resection and reconstruction. However, venous reconstruction often demands complex hepatobiliary and vascular surgical procedures. In this study, we report a simple patch repair technique for venous reconstruction using the repermeabilized umbilical vein of the round ligament. METHODS: We reviewed the outcomes of eleven patients who underwent venous wedge resection and patch repair using the repermeabilized umbilical vein of the round ligament at our institution...

INTRODUCTION: Recent literature has reported an association between maternal supine sleep position and stillbirth during late pregnancy. In this position the gravid uterus almost completely obstructs the inferior vena cava. A small number of women experience supine hypotension, thought to be due in part to inadequate collateral venous circulation. The aim of this paper is to review the literature describing the anatomy of the collateral venous system and in particular the azygos system, the abdominal portion of which has not been well studied...

The most common extraintestinal complication of Entamoeba histolytica is amoebic liver abscess (ALA). Hepatic vein and inferior vena cava (IVC) thrombosis are rare but well-documented complications of ALA, typically attributed to mechanical compression and inflammation associated with a large abscess. We present a case of a previously healthy 43-year-old Canadian man presenting with constitutional symptoms and right upper quadrant abdominal pain. He was found to have thrombophlebitis of the IVC, accessory right hepatic vein, and bilateral iliac veins...

Atrial fibrillation (AF) is a really uncommon arrhythmia in newborns. Here, we report the case of a 1-day-old infant who was recovered in Neonatal Intensive Care Unit for a twin-to-twin transfusion. The appearance of an unexpected AF was registered at his continuous electrocardiographic monitoring. Both chest X-ray and echocardiographic examination revealed the anomalous insertion of the tip of a central venous catheter (CVC) into the heart ('umbilical artery → inferior vena cava → right atrium → patent foramen ovale → left atrium')...

BACKGROUND: Pig-to-nonhuman primate orthotopic liver xenotransplantation is often accompanied by thrombocytopenia and coagulation disorders. Furthermore, the release of cytokines can trigger cascade reactions of coagulation and immune attacks within transplant recipients. To better elucidate the process of inflammation in liver xenograft recipients, we utilized a modified heterotopic auxiliary liver xenotransplantation model for xeno-immunological research. We studied the cytokine profiles and the relationship between cytokine levels and xenograft function after liver xenotransplantation...

BACKGROUND: Postoperative hepatic decompensation is a serious complication of liver resection in patients undergoing hepatectomy for hepatocellular carcinoma. Liver fibrosis and clinical significant portal hypertension are well-known risk factors for hepatic decompensation. Liver stiffness measurement is a noninvasive method of evaluating hepatic venous pressure gradient and functional hepatic reserve by estimating hepatic fibrosis. Effectiveness of liver stiffness measurement in predicting persistent postoperative hepatic decompensation has not been investigated...

Femoral vein is the usual approach to balloon pulmonary valvuloplasty (BPV). However, alternative access may be mandated in some peculiar situations. We hereby report a 10-year-old patient with symptomatic severe valvular pulmonary stenosis with interrupted inferior vena cava which was successfully treated with transjugular BPV. Technical considerations for this approach as well as other possible options for such patients are discussed.

Venous aneurysms are rare lesions, they have been reported in most venous territories. Abdominal location is unusual. A 61-year-old man presented with chest pain and dyspnea attributed to pulmonary embolism. Computed tomography of the abdomen showed multiple thrombosed venous aneurysms of the left external iliac vein and the inferior vena cava. There were no signs of rupture. The patient received anticoagulant treatment. He had no surgical treatment.
