The patient was a boy of 7 years and 5 months of age, who underwent LDLT for acute liver failure at 10 months of age. HV stent placement was performed 8 months after LDLT because of intractable HV stenosis. At 7 years of age, his liver function deteriorated due to chronic rejection. The patient therefore underwent living donor liver retransplantation from his father. The HV was transected with the stent in situ. The IVC was resected due to stenosis. The pericardial cavity was opened and detached around the IVC to elongate the IVC...

Thrombosis of the inferior vena cava (IVC) continues to be a rare event and there is a scarcity of evidence with regard to its etiology. One source for IVC thrombosis is external compression from adjacent structures. In this case series we present one case of IVC thrombosis caused by a severely distended bladder and a case of external iliac thrombosis caused by external compression from an abnormally enlarged uterus. The treatment of each case is varied and included novel oral anticoagulation (NOAC), catheter-directed thrombolysis in conjunction with mechanical thrombectomy, or a combination of these...

The precision of echocardiography in estimating pulmonary pressures has been debated. A value of right atrial pressure (RAP) is needed for pulmonary pressure estimation, and it could be partly responsible for the estimation error. Several schemes based on the inferior vena cava (IVC) are commonly used in clinical practice and in experimental studies for RAP estimation. However, the majority lack proper validation, and thus far, no study has compared them all. In this prospective, blinded study, a comprehensive transthoracic echocardiography was performed on 200 patients referred for right heart catheterization...

Colombian Ministry of Health Resolution 1229 of 2013 established that health inspection, surveillance, and control (IVC, Spanish acronym) should be based on a risk-focused approach. In 2014 Colombia´s National Food and Drugs Surveillance Institute (INVIMA) designed and implemented a risk-based health surveillance model called IVC-SOA. This model measures the risks of drugs, medical devices, food, and cosmetics by taking into account three factors: severity of the product (S), occurrence of product failure (O), and the potentially affected population (A) - hence its name, SOA...

BACKGROUND: Diagnosis of hepatocellular carcinoma (HCC) can be established with near certainty by correlating radiological imaging with clinical presentation. However, in the absence of diagnostic certainty, biopsy of liver tissue is mandatory for optimal management. We present our management of a patient with advanced liver disease who presented with an IVC mass extending into the right atrium, with co-existing liver lesions not meeting criteria for an imaging diagnosis of HCC. CASE PRESENTATION: A 62-year-old male with Child-Pugh C liver cirrhosis presented with decompensated liver failure...

CLINICAL INTRODUCTION: A 72-year-old woman presented with an 8-year history of palpitations occurring every few weeks. They were sudden in onset, were associated with dizziness and could last for up to 2 hours. She was prescribed bisoprolol which reduced the frequency of events but did not abolish them. Baseline ECG and echocardiography were normal. She was referred for electrophysiological study. Despite initial difficulties, diagnostic catheters were placed in the right ventricular (RV) apex and in the coronary sinus (CS) via the right internal jugular vein and superior vena cava (SVC) (figure 1A)...

BACKGROUND: The majority of iliac venous obstructions occur on the left side, and endovascular therapy has become the first line treatment for this condition. A left common iliac venous stent will protrude into the inferior vena cava (IVC) to some extent, thereby covering the contralateral common iliac vein (CIV) outflow. This may increase the risk of thrombosis of the contralateral iliac vein. The aim of this paper was to determine the rate of, and factors associated with, contralateral lower limb venous thrombosis after stenting, and to evaluate the results of salvage revascularisation...

PURPOSE: Central vein point-of-care ultrasonography must be reproducible to detect intravascular volume changes. We sought to determine which measurement step, image acquisition or interpretation, could be more compromising for reproducibility. METHODS: Three investigators each acquired inferior vena cava (IVC) and internal jugular (IJV) vein ultrasonographic sequences (US) from a convenience sample of 21 hospitalized general medicine participants and then interpreted each US three separate times...

Retrievable inferior vena cava (IVC) filters are increasingly used in patients with venous thromboembolism (VTE) who have contraindications to anticoagulant therapy. However, previous studies have shown that many retrievable filters are left permanently in patients. This study aimed to identify the common indications for IVC filter insertion, the filter retrieval rate, and the predictive factors for filter retrieval attempts. To this end, a retrospective cohort study was performed at a tertiary care center in South Korea between January 2010 and May 2016...

BACKGROUND: Literature supports that very rarely the venom of "Hemotoxic Snake" (Russell's Vipers) affect haemostasis by secreting thrombin-like enzyme which promotes formation of unstable clots. Such clots could lead to fibrin deposition in micro circulation that in turn consume platelets and coagulation factors (consumption coagulopathy). Clinical presentation is mainly spontaneous bleeding and coagulopathy. In this case the significant effects of altered coagulation were observed in retropetitoneum and the patient presented in casuality as acute abdomen...

Iatrogenic simultaneous inferior vena cava (IVC) and iliac vessel injury is a rare entity. Ligation of the IVC in a life-threatening situation is well reported in the literature. Our case demonstrates that such a clinical situation requires optimization of fluid volume and management of sequelae such as deep vein thrombosis.

Although widely used as a preclinical model for studying venous diseases, there is a scarcity of in vivo characterizations of the naïve murine venous system. Additionally, previous studies on naïve veins (ex vivo) have not included the influence of surrounding structures and biomechanical forces. Using MRI, we noninvasively quantified the cross-sectional area, cyclic strain, and circularity of the venous system in young and old, male and female C57BL/6 mice. We investigated the most common venous locations used to perform venous disease research: the common jugular vein, suprarenal inferior vena cava (IVC), infrarenal IVC, common iliac vein, and common femoral vein...

Purpose: To examine whether tumor staging by upfront (18)F-fluoro-deoxy-glucose-positron emission tomography/computed tomography (PET/CT) leads to improved discrimination of survival, when compared with traditionally used imaging strategies based on chest X-ray + head and neck magnetic resonance imaging (CXR/MRI) or chest computed tomography + head and neck MRI (CCT/MRI) in patients with head and neck squamous cell carcinoma (HNSCC). Methods: Blinded prospective cohort study based on paired data. Consecutive patients with histologically verified primary HNSCC were recruited at Odense University Hospital from September 2013 to March 2016...
