BACKGROUND: Injection-site vein loss and skin abscesses impose significant morbidity on people who inject drugs (PWID). The two common forms of street heroin available in the USA include black tar and powder heroin. Little research has investigated these different forms of heroin and their potential implications for health outcomes. METHODS: A multiple-choice survey was administered to a sample of 145 participants seeking services at reduction facilities in both Sacramento, CA and greater Boston, MA, USA...

INTRODUCTION: Venous access devices are essential for the provision of care for patients requiring chemotherapy. Totally implanted venous access devices (TIVADs), also known as ports, are an option for infusion care. Medical devices have an impact upon patient quality of life. We assessed the impact on quality of life and satisfaction with their venous device, for patients with a chest TIVAD versus an upper arm TIVAD. MATERIALS AND METHODS: Sequential subjects were administered a questionnaire, "Quality of Life Assessment, Venous Device - Port (QLAVD-P)" at the time of their TIVAD removal...

PURPOSE: To evaluate retrospectively the fracture risk of totally implanted venous access devices connected to Groshong silicone (SC) versus polyurethane (PU) catheters, inserted via the internal jugular vein. MATERIALS AND METHODS: The study population comprised 384 SC and 221 PU central venous catheters implanted via the internal jugular vein. The presence of catheter fracture was evaluated. Variables possibly related to catheter fracture were evaluated. First, in order to determine the factors associated with fracture, fracture rates were compared with the log-rank test between the two groups divided by each of the variables...

OBJECTIVE: To present a simple and affordable model able to properly simulate an ultrasound-guided venous access. DESIGN: The simulation was made using a latex balloon tube filled with water and dye solution implanted in a thawed chicken breast with bones. RESULTS: The presented model allows the simulation of all implant stages of a central catheter. The obtained echogenicity is similar to that observed in human tissue, and the ultrasound identification of the tissues, balloon, needle, wire guide and catheter is feasible and reproducible...

We report a rare, but serious, complication of a malpositioned umbilical venous catheter in a term male infant who developed laceration, hematoma, and necrosis of liver, ascites, and left-sided obstructive uropathy secondary to extravasation of total parenteral nutrition. Abdominal paracentesis confirmed the presence of parenteral nutrition in the peritoneal cavity. Although, the umbilical venous catheterization is a common intravenous access used in neonatal intensive care units, judicious continued monitoring of its use should be practiced to avoid serious complications...

Retrospective and prospective studies unambiguously show that prophylactic treatment of severe hemophilia A or B should be started as primary prophylaxis at 1-2 years' of age and ideally before the first joint bleed. The dose and dose frequency should be individually tailored depending on the goal of treatment, venous access and the bleeding phenotype. The circumstances during the first exposures of factor VIII concentrates in hemophilia A may have an impact on the risk of developing inhibitors. Enhanced half-life products, in particular in hemophilia B, will facilitate treatment in patients with difficult venous access but also in achieving a higher trough level...

The group of new oral anticoagulants or NOACs, now termed direct oral anticoagulants or DOACs, with their favourable results from large scale phase III clinical trials, represent a major advancement and expanded armamentarium in antithrombotic therapy. Dabigatran, rivaroxaban, apixaban and edoxaban are now in clinical routine use for prevention and treatment of arterial and venous thrombotic diseases as addressed in their clinical trials. Usage of the DOACs is expected to increase as clinicians gain more experience and reassurance with data from the real world studies which are generally consistent with that from clinical trials...

BACKGROUND: Pediatric apheresis for peripheral blood stem cell transplantation should be carried out with due concern for low corporeal blood volume and vulnerability to hypocalcemia-related complications, hypovolemic shock, and hypervolemic cardiac overload. STUDY DESIGN AND METHODS: We retrospectively investigated a total of 267 apheresis procedures from 1990 to 2013 on 93 children between 0 and 10 years old, including 89 patients and 4 healthy donors, with body weights of 6...

OBJECTIVE: We hypothesized that decreasing vein compliance would protect the vein against stretch injury and reduce intimal hyperplasia (IH). BACKGROUND: Although arteriovenous fistulas (AVFs) are the criterion standard for vascular access, their effectiveness is limited by poor patency with 40% to 60% failing due to IH. Venous stretch injury from exposure to arterial pressure induces IH. Photochemical tissue passivation (PTP) crosslinks adventitial collagen, decreasing vein compliance to resemble that of an artery...

OBJECTIVES: The common femoral artery is the standard site for immediate vascular access when initiating adult venoarterial extracorporeal membrane oxygenation. However, this approach is fraught with problems such as femoral artery occlusion, distal limb ischemia, reperfusion injury resulting in compartment syndrome, retroperitoneal hemorrhage, thrombosis, embolization, and most importantly, pulmonary edema. Here, we show our preference of using the subclavian artery with a side graft as a different cannulation technique for outflow of extracorporeal membrane oxygenation, which can avoid complications associated with different access techniques...

INTRODUCTION: Currently, venography is the standard diagnostic method to examine veins before implementing access, which is invasive in nature. Computerized tomography venography (CTV) can simultaneously indicate deep and superficial venous systems in the upper extremity and their relation to the surrounding anatomical structures; however, its diagnostic value in the detection of central venous disease has yet to be defined. The aim of this study was to determine the diagnostic value of CT venography compared to venography in the diagnosis of stenosis and the occlusion of subclavian veins and the superior vena in renal failure patients...

OBJECTIVES: Our 2007 study of 32 patients with ovarian cancer reported the possible involvement of tissue factor (TF) in the development of venous thromboembolism (VTE) before treatment, especially in clear cell carcinoma (CCC). This follow-up study further investigated this possibility in a larger cohort. METHODS: We investigated the intensity of TF expression (ITFE) and other variables for associations with VTE using univariate and multivariate analyses in 128 patients with epithelial ovarian cancer initially treated between November 2004 and December 2010, none of whom had received neoadjuvant chemotherapy...

Central venous access has traditionally been performed on the basis of designated anatomical landmarks. However, due to patients' individual anatomy and vessel pathology and depending on individual operators' skill, this landmark approach is associated with a significant failure rate and complication risk. There is substantial evidence demonstrating significant improvement in effectiveness and safety of vascular access by realtime ultrasound (US)-guidance, as compared to the anatomical landmark-guided approach...

OBJECTIVE: In patients with a high risk of fistula immaturity, we created arteriovenous fistulas (AVFs) combined with brachial artery superficialization. With this procedure, the superficialized arteries are used as drawing routes and the AVFs as returning routes. This is a technical report about AVFs combined with brachial artery superficialization. METHODS: Twenty-four consecutive patients with a high risk of fistula immaturity who underwent AVFs with brachial artery superficialization were included in this single-center retrospective study...

Maintenance of central venous access in patients with chronic medical conditions such as short bowel syndrome demands forethought and ingenuity. We describe an innovative technique for re-utilizing central venous access sites in patients who have chronic central venous access needs. Records of patients undergoing this technique were reviewed between August 2012 and December 2015. The technique involves "cutting-down" to the sterile fibrous tunnel that naturally forms around tunneled catheters. The fibrous sheath is then isolated and controlled much as would be done for a venous "cut-down...

AIM: This new laser facilitated 'inside-out' technique was used for transvenous pacemaker insertion in a pacemaker-dependent patient with bilateral subclavian occlusion and a failed epicardial system who is not suitable for a transfemoral approach. METHOD AND RESULTS: Procedure was undertaken under general anaesthesia with venous access obtained from right femoral vein and left axillary vein. 7F multipurpose catheter was used to enter proximal edge of the occluded segment of subclavian vein via femoral approach, which then supported stiff angioplasty wires and microcatheters to tunnel into the body of occlusion...

PURPOSE: To describe all post-insertion complications involving most used intravascular access, and to determine whether the use of a new-generation transparent dressing (3M™ IV Advanced) might reduce their number and impact on ICU patient outcomes. METHODS: Patients older than 18, with an expected length of stay ≥48 h and requiring at least one central venous catheter (CVC), arterial catheter (AC), haemodialysis catheter (HDC), pulmonary arterial catheters (PAC) or peripheral venous catheter (PVC) were randomized into two groups: a new-generation transparent dressing, or the hospital's classical transparent dressing, and were followed daily for any infectious and non-infectious complications...
