Viridans group streptococcus is an infrequent cause of osteomyelitis that is found in association with infective endocarditis. Only a few studies report viridans osteomyelitis in the absence of endocarditis. Vertebral pyogenic osteomyelitis can sometimes be complicated by psoas or paraspinal abscesses. These intra-abdominal and/or pelvic collections can very rarely result in venous thrombosis. A paraspinal abscess resulting in inferior vena cava (IVC) thrombosis has only been reported once in the literature...

Chronic post-thrombotic obstruction of the inferior vena cava (IVC) or iliocaval junction is an uncommon complication of long indwelling IVC filter. When such an obstruction is symptomatic, endovascular treatment options include stent placement with or without filter retrieval. Filter retrieval becomes increasingly difficult with longer dwell times. We present a case of symptomatic post-thrombotic obstruction of the iliocaval junction related to Günther-Tulip IVC filter (Cook Medical Inc, Bloomington, IN) with dwell time of 4753 days, treated successfully with endovascular filter removal and stent reconstruction...

A 38-year-old woman had developed an abdominal distention, lower extremity edema, and dyspnea. Imaging examination revealed a large mass in the right atrium which was connected to lesions within the inferior vena cava. Although complete resection of the mass was not possible, partial surgical tumor resection was performed to avoid pulmonary embolization and circulatory collapse. Leiomyosarcoma was diagnosed histologically, and chemotherapy (doxorubicin) followed by radiotherapy was started. By reviewing papers published in the past 10 years that included 322 patients, we also discuss the clinical presentations and prognosis of leiomyosarcoma in the inferior vena cava...

BACKGROUND: Combined liver and inferior vena cava (IVC) resection followed by IVC and/or hepatic vein reconstruction (HVR) is a curative operation for selected patients with hepatocellular carcinoma (HCC) invading the hepatocaval confluence. The present study aimed to elucidate the prognostic factors for patients with HCC invading the hepatocaval confluence. METHODS: Forty-two consecutive patients underwent hepatectomy, combined with IVC replacement and/or HVR for HCC between January 2009 and December 2014 were included in this study...

The blood-brain barrier (BBB) plays important roles in both the physiological and pharmacological state of the brain. Transiently enhancing the permeability of the BBB may allow use of more types of medications for neuropsychiatric diseases. Several studies have demonstrated that seizures cause a transient decrease in BBB integrity. We studied the timing of BBB changes following seizures and the role of astrocytes in this process. Rats received 10 applications of electroconvulsive stimulation (ECS). They were then infused with sodium fluorescein, a fluorescent substance that rarely passes the BBB, via the inferior vena cava...

Ultrasound-facilitated, catheter-directed, low-dose fibrinolysis minimizes the risk of intracranial bleeding compared with systemic full-dose fibrinolytic therapy for pulmonary embolism (PE). However, major bleeding is nevertheless a potential complication. We analyzed the 150-patient SEATTLE II trial of submassive and massive PE patients to describe those who suffered major bleeding events following ultrasound-facilitated, catheter-directed, low-dose fibrinolysis and to identify risk factors for bleeding. Major bleeding was defined as GUSTO severe/life-threatening or moderate bleeds within 72 hours of initiation of the procedure...

The standard of care for localized hepatocellular carcinoma (HCC) is surgical resection. For patients who decline or who are unfit for surgery, stereotactic body radiotherapy (SBRT) is emerging as a viable treatment approach. We present a case of a 77-year-old female in whom an early stage HCC was incidentally discovered. Given her religious edicts as a devout Jehovah's Witness and her subsequent desire to avoid a blood transfusion, she declined surgical resection or transplant due to the risk of hemorrhage...

BACKGROUND Right lobe living donor liver transplantation (LDLT) remains the most common form of liver transplantation in Asia. However, reconstruction of the venous outflow in a right liver allograft may pose technical difficulties if hepatic venous variations are present. Recently, much emphasis has been given to the reconstruction of large and multiple inferior right hepatic veins (IRHVs). The method of reconstructive technique, type of vascular grafts, and the outcome after the procedure have been a point of debate...

Inferior vena cava (IVC) filters are medical devices designed to provide a mechanical barrier to the passage of emboli from the deep veins of the legs to the heart and lungs. Despite decades of development and clinical use, IVC filters still fail to prevent the passage of all hazardous emboli. The objective of this study is to (1) develop a resolved two-way computational model of embolus transport, (2) provide verification and validation evidence for the model, and (3) demonstrate the ability of the model to predict the embolus-trapping efficiency of an IVC filter...

This case describes a 36-year-old woman, gravida 4 para 2 at 41 weeks and 3 days gestation, who appeared unconscious during labour for 75 minutes. After excluding physical disorders, it transpired that she was having a conversion disorder. A patient with a decreased level of consciousness in childbirth must be assessed using the ABCDE method, positioned in left lateral tilt to prevent inferior vena cava compression. After stabilization of the vital functions and establishing the patient's history, physical examination and laboratory tests are components of the initial clinical assessment...

We report a case of combined hepatocellular-cholangiocarcinoma with stem cell features, cholangiolocellular subtype arising about 15 years after placement of an inferior vena cava stent for primary Budd-Chiari syndrome. Pre-surgical differentiation of the tumor from hepatocellular carcinoma was difficult because of elevated levels of alpha-fetoprotein and hypervascularity in the arterial phase. Histopathological examination revealed atypical cells forming ductal and alveolar structures showing a vague border with the surrounding liver...

Intravenous leiomyomatosis (IVL) is a rare benign tumor of the uterus mesoderm, which can spread via the vein, from the micro-vein to the inferior vena cava, and even to the right atrium. IVL was first described this disease in 1896 and the first presented case of IVL with right atrium extension in the autopsy was described in 1907. On rare occasions, the tumors may extend into the regional and systemic veins, thus reaching the heart. This may subsequently cause intracardiac leiomyomatosis (ICL), which may lead to congestive heart failure and on occasion, sudden fatalities...

Hepatocellular carcinoma(HCC)with severe vascular invasion has a dismal prognosis, and there is no well-established effective therapy. We report an 84-year-old man who benefited from multiple transcatheter arterial chemoembolization (TACE)treatments for advanced HCC with severe vascular invasion. Initial CT revealed a recurrent, poorly differentiated HCC with tumor thrombus in the inferior vena cava(IVC)and right atrium(Vv3). Two cycles of TACE with 5-FU, DOC, MMC, and superabsorbent polymer microspheres(SAP-MS)with BV resulted in considerable reduction of the tumor thrombus...

To investigate the clinical characteristics, treatments and prognosis of renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusions (Xp11.2 tRCC), the epidemiological features and treatment results of 34 cases of Xp11.2 tRCC, which were diagnosed by immunohistochemistry staining of TFE3 and fluorescence in situ hybridization at our center, were retrospectively reviewed. The 34 patients included 21 females and 13 males aged 3 to 64 years (median age: 27 years). Four patients were children or adolescents (<18 years of age), and 26 patients were young or middle-aged adults (18-45 years)...

BACKGROUND: The progression of hepatic disease in adult Fontan patients is not well understood. They reviewed the experience with serial cardiac MRIs (CMR) in adult Fontan patients to determine if hepatic anatomic markers of prolonged Fontan exposure were present and if clinical predictors of progressive hepatic congestion could be identified. METHODS AND RESULTS: A retrospective cohort study of all adult Fontan patients who had undergone at least two CMRs was performed...

In 2005, a 48-year-old man with a spinal cord injury had an inferior vena cava filter placed for recurrent deep vein thrombosis and pulmonary embolism. He was referred for filter retrieval after a computed tomography scan demonstrated caval stenosis and 2 fractured filter arms, 1 in a pulmonary artery and 1 penetrating into the retroperitoneum and impinging on the aorta. During retrieval, 1 arm was inadvertently advanced into the aorta, and embolization of the arm occurred to the left profunda femoris artery...
