BACKGROUND: Deep venous thrombosis (DVT) arises with an incidence of about 1 per 1000 persons per year; 4-10% of all DVTs are located in an upper extremity (DVT-UE). DVT-UE can lead to complications such as post-thrombotic syndrome and pulmonary embolism and carries a high mortality. METHODS: This review is based on pertinent literature, published from January 1980 to May 2016, that was retrieved by a systematic search, employing the PRISMA criteria, carried out in four databases: PubMed (n = 749), EMBASE (n = 789), SciSearch (n = 0), and the Cochrane Library (n = 12)...

BACKGROUND: Heparin-induced thrombocytopenia (HIT) is an adverse drug reaction presenting as a prothrombotic disorder related to antibody-mediated platelet activation. It is a paradoxical immune reaction resulting in thrombin generation in vivo, which leads to a hypercoagulable state and the potential to initiate venous or arterial thrombosis. A number of factors are thought to influence the incidence of HIT including the type and preparation of heparin (unfractionated heparin (UFH) or low molecular weight heparin (LMWH)) and the heparin-exposed patient population, with the postoperative patient population at higher risk...

PURPOSE: Stenosis is the main cause of arteriovenous fistula (AVF) failure. It is still unclear whether surveillance based on vascular access blood flow (QA) enhances AVF function and longevity. METHODS: We conducted a three-year follow-up randomized, controlled, multicenter, open-label trial to compare QA-based surveillance and pre-emptive repair of subclinical stenosis with standard monitoring/surveillance techniques in prevalent mature AVFs. AVFs were randomized to either the control group (surveillance based on classic alarm criteria; n = 104) or to the QA group (QA measured quarterly using Doppler ultrasound [M-Turbo®] and ultrasound dilution [Transonic®] added to classic surveillance; n = 103)...

Chronic indwelling central venous catheters can result in formation of fibrin sheaths increasing risk of occlusion, thrombosis and infection. Endovascular infection of right-sided heart structures induced by such sheaths is very rare. A 48-year-old woman with end-stage renal disease initially treated for diabetic ketoacidosis developed persistent Staphylococcus epidermidis bacteraemia without an identifiable source. Although transthoracic echocardiography was unremarkable, transoesophageal echocardiography revealed a fibrin sheath and vegetations in superior vena cava-right atrium junction, which was the site of the tip of a central catheter that had been removed 2 months prior, consistent with fibrin sheath-associated endovascular infection...

INTRODUCTION: Patients with cancer are at increased risk of thrombosis, particularly those with central venous catheter (CVC) placement, which may predispose to the development of upper extremity deep vein thrombosis (UEDVT). Standard treatment includes low molecular weight heparin (LMWH) or LMWH bridged to warfarin. The direct oral anticoagulants (DOACs) have become standard of care for uncomplicated venous thromboembolism (VTE), but research in patients with cancer is ongoing. OBJECTIVES: To assess rivaroxaban monotherapy in patients with cancer who develop UEDVT due to CVC for preservation of line function, and safety outcomes of VTE recurrence, bleeding risk and death...

Background/Aims: The strategy of access care at out center involves the use of ultrasound (USG) in case of physical examination (PE) abnormality. USG determines the need of angiography. This study investigated the possible association between the need for percutaneous transluminal angioplasty (PTA) and hemodynamic parameters of USG. The study also assessed the effects of this monitoring strategy on outcomes in comparison with a historical control. Methods: A retrospective study of the medical records of 127 patients (65 PTA, 62 non-PTA) was conducted...

About 20% of patients suffer from venous thromboembolism (VTE) during oncology disease. Active cancer, along with cancer therapy, increases the risk of VTE, especially in the first 6 months after diagnosis. Most often VTE accompanies haematological malignancies and CNS tumours, and gastrointestinal, breast, lung, ovary and uterine cancer. The presence of distant metastases, together with the implantation of a central venous catheter, increases the risk even more. A cancer patient also has a 2-5× higher risk of recurrence of VTE during anticoagulant therapy than patients without a malignancy, as well as a 2-6× higher risk of serious bleeding...

BACKGROUND: The use of ultrasound guided percutaneous transluminal angioplasty (UG-PTA), which use ultrasound as an imaging modality, is an evolving strategy. But, in Korea, this method is rarely used. We report our experiences with UG-PTA with respect to technical success rates and complication rates compared to conventional PTA (C-PTA), performed between 2010 and 2015 at Samsung Changwon Hospital, Korea. METHODS: In our series, 53 cases of UG-PTA and 90 cases of C-PTA were reviewed, respectively...

Central venous access device (CVAD)-related thrombosis (CRT) is a common complication among patients requiring central venous access as part of their medical care. Complications of CRT include pulmonary embolism, recurrent deep venous thrombosis, loss of central venous access and post-thrombotic syndrome. Patient, device and treatment-related factors can influence the risk of CRT. Despite numerous randomized controlled trials, the clinical benefit of pharmacologic thromboprophylaxis for prevention of CRT remains to be established...

BACKGROUND: Due to the high incidence of thromboembolic events (deep venous thrombosis [DVT] and pulmonary embolus [PE]) after injury, many trauma centers perform lower extremity surveillance duplex ultrasounds. We hypothesize that trauma patients are at a higher risk of upper extremity DVTs (UEDVTs) than lower extremity DVTs (LEDVTs), and therefore, all extremities should be evaluated. MATERIALS AND METHODS: A retrospective chart and trauma registry review of Intensive Care Unit trauma patients with upper and LEDVTs detected on surveillance duplex ultrasound from January 2010 to December 2014 was carried out...

The Centers for Disease Control and Prevention guidelines for the prevention of catheter-related bloodstream infections suggest using "a subclavian site, rather than an internal jugular or a femoral site, in adult patients." This recommendation is based on evidence of lower rates of thrombosis and catheter-related bloodstream infections in patients with subclavian central venous catheters (CVCs) compared to femoral or internal jugular sites. However, preference toward a subclavian approach to CVC insertion is hindered by increased risk of mechanical complications, especially pneumothorax, when compared to other sites...

INTRODUCTION: Patients with chronic kidney disease (CKD) are at increased risk for thrombotic complications. The use of central venous catheters as dialysis vascular access additionally increases this risk. We describe the first case of Budd-Chiari syndrome (BCS) secondary to central venous catheter misplacement in a patient with CKD. CASE REPORT: A 30-year-old female patient with HIV/AIDS and CKD on hemodialysis was admitted to the emergency room for complaints of fever, prostration, and headache in the last six days...

Venous thromboembolic disease in childhood is a multifactorial disease. Risk factors include acquired clinical risk factors such as a central venous catheter and underlying disease and inherited thrombophilia. Inherited thrombophilia is defined as a genetically determined tendency to develop venous thromboembolism. In contrast to adults, acquired clinical risk factors play a larger role than inherited thrombophilia in the development of thrombotic disease in children. The contributing role of inherited thrombophilia is not clear in many pediatric thrombotic events, especially catheter-related thrombosis...

Critically ill children and those sustaining severe traumatic injuries are at higher risk for developing venous thromboembolism (VTE) than other hospitalized children. Multiple factors including the need for central venous catheters, immobility, surgical procedures, malignancy, and dysregulated inflammatory state confer this increased risk. As well as being at higher risk of VTE, this population is frequently at an increased risk of bleeding, making the decision of prophylactic anticoagulation even more nuanced...

There is an increasing incidence of infective endocarditis secondary to central venous catheters, which is termed as 'healthcare-associated infective endocarditis'. There is an increased risk of getting infective endocarditis in conditions with malnutrition and also if the tip of the central venous catheter is deep in the right atrium close to the tricuspid valve. We present a case of 31-year-old female who had all these risk factors. She was admitted to the hospital for the work up of the weight loss and was diagnosed with celiac disease...

BACKGROUND: With the increasing frequency of tunneled hemodialysis catheter use there is a parallel increase in the need for removal and/or exchange. A small but significant minority of catheters become embedded or 'stuck' and cannot be removed by traditional means. Management of embedded catheters involves cutting the catheter, burying the retained fragment with a subsequent increased risk of infections and thrombosis. Endoluminal dilatation may provide a potential safe and effective technique for removing embedded catheters, however, to date, there is a paucity of data...

Data on paediatric pulmonary embolism (PE) are scarce. We sought to systematically review the current literature on childhood PE and conducted a search on paediatric PE via PubMed (1946-2013) and Embase (1980-2013). There was significant heterogeneity in reported data. Two patterns were noted: classic thromboembolic PE (TE-PE) and in situ pulmonary artery thrombosis (ISPAT). Mean age of presentation for TE-PE was 14.86 years, and 51 % of cases were males. The commonest method for diagnosis of TE-PE was contrast CT with angiography (74 % of patients)...
