Abstract The clinical management of individuals with hereditary hypercoaguable disorders has evolved from initial broad recommendations of lifelong anticoagulation after first event of venous thromboembolism to a more intricate individualized risk-benefit analysis as studies have begun to delineate the complexity of interactions of acquired and hereditary factors which determine the predilection to thrombosis. The contribution of thrombophilic disorders to risk of thrombotic complications of pregnancy, organ transplantation, central venous catheter and dialysis access placement have been increasingly recognized. The risk of thrombosis must be weighed against risk of long-term anticoagulation in patients with venous thromboembolism. Thrombophilia screening in select populations may enhance outcome.

Abstract Thrombotic complications associated with the use of central venous catheters (CVCs) are common and lead to distressing patient symptoms, catheter dysfunction, increased risk of infections, long-term central venous stenosis, and considerable costs of care. Risk factors for catheter-related thrombosis include use of larger, multilumen, and peripherally inserted catheters in patients with cancer receiving chemotherapy. Symptomatic catheter-related thrombosis is treated with anticoagulation, generally without removing the catheter. The intensity and duration of anticoagulation depend on the extent of thrombosis, risk of bleeding, and need for continued use of a CVC. To date, the clinical benefit of prophylactic doses of anticoagulant has been disappointing and these agents are not used routinely for this purpose. This chapter focuses on recent evidence, remaining controversies, and practical approaches to reducing the burden of thrombosis associated with CVCs.

Abstract Background Peritoneal dialysis (PD) is an underutilized modality for hospitalized patients with an urgent need to start renal replacement therapy in the USA. Most patients begin hemodialysis (HD) with a tunneled central venous catheter (CVC). Methods We examined the long-term burden of dialysis modality-related access procedures with urgent-start PD and urgent-start HD in a retrospective cohort of 73 adults. The number of access-related (mechanical and infection-related) procedures for each modality was compared in the first 30 days and cumulatively through the duration of follow-up. Results Fifty patients underwent CVC placement for HD and 23 patients underwent PD catheter placement for urgent-start dialysis. Patients were followed on average >1 year. The PD group was significantly younger, with less diabetes, with a higher pre-dialysis serum creatinine and more likely to have a planned dialysis access. The mean number of access-related procedures per patient in the two groups was not different at 30 days; however, when compared over the duration of follow-up, the number of access-related procedures was significantly higher in the HD group compared with the PD group (4.6 ± 3.9 versus 0.61 ± 0.84, P < 0.0001). This difference persisted when standardized to procedures per patient-month (0.37 ± 0.57 versus 0.081 ± 0.18, P = 0.019). Infection-related procedures were similar between groups. Findings were the same even after case-matching was performed for age and diabetes mellitus with 18 patients in each group. Conclusions Urgent-start PD results in fewer invasive access procedures compared with urgent-start HD long term, and should be considered for urgent-start dialysis.

Abstract Background Cannulation of a central venous catheter is sometimes associated with serious complications. When arterial cannulation occurs, attention must be given to removal of a catheter. Case presentation A 62-year-old man was planned for emergency thoracic endovascular aortic repair. After the induction of anesthesia, a central venous catheter was unintentionally inserted into the right subclavian artery. We planned to remove the catheter. Since we considered that surgical repair would be highly invasive for the patient, we decided to remove it using a percutaneous intravascular stent. A stent was inserted through the right axillary artery. The stent was expanded immediately after the catheter was removed. Post-procedural angiography revealed no leakage from the catheter insertion site and no occlusion of the right subclavian and vertebral arteries. There were no obvious hematoma or thrombotic complications. Conclusions A catheter that has been misplaced into the right subclavian artery was safely removed using an intravascular stent.

Background: Achieving a reliable venous access in a particular subset of patients and/or in emergency settings can be challenging and time-consuming. Furthermore, many hospitalized patients do not meet the criteria for central venous catheter positioning, unless an upgrade of the treatment is further needed. The mini-midline catheter has already showed to be reliable and safe as a stand-alone device, since it is easily and rapidly inserted and can indwell up to 1 month. Methods: In this further case series, we retrospectively evaluated data from 63 patients where a previously inserted mini-midline catheter was upgraded to a central venous catheter (the devices inserted in the arm replaced by peripherally inserted central catheter and others inserted “off-label” in the internal jugular replaced by single lumen centrally inserted central catheter), being used as introducer for the Seldinger guidewire. Results: The guidewire replacement was been made even early (after 1 day) or late (more than 10 days), usually following a need for an upgrade in treatment. No early or late complications were reported. Conclusion: According to the preliminary data we collected, this converting procedure seems to be feasible and risk-free, since neither infectious nor thrombotic complications were reported.

AbstractPeripheral intravenous (PIV) catheters are the most commonly used catheters in hospitals, with up to 70% of patients requiring a peripheral venous line during their hospital stay. This represents 200 million PIV catheters used per year in acute-care hospitals in the United States alone. These medical devices are also used in other health care settings, such as long-term care facilities and nursing homes, and common indications include the administration of medications, nutrients, and fluids. These catheters require proper maintenance and care to avoid complications such as phlebitis, infiltration, occlusion, local infection, and bloodstream infection. Recently it has been suggested that PIV catheter use may lead to a higher rate of complications than previously thought. This is important because some studies have claimed that the rate of bloodstream infections due to PIV catheters is actually comparable to the rates observed with central venous catheters, rather than much lower as previously thought. Moreover, catheter-related infections are now seen as largely preventable. Our goal was to review the current literature and provide an overview of the various approaches used to manage PIV catheter sites as well as review current recommendations.

Abstract Background: Long term venous catheters have been used to deliver specialized therapies since 1968. The ideal tip position of a central venous catheter provides reliable venous access with optimal therapeutic delivery, while minimizing short-and long-term complications. Ideal position limits have evolved and narrowed over time, making successful placement difficult and unreliable when depending exclusively on the landmark technique. Objective: To review and analyze contemporary literature and calculate an overall accuracy rate for first attempt placement of a PICC catheter in the ideal tip position. Methods: Key PICC placement terms were used to search the database PubMED-indexed for MEDLINE in June and October, 2009. The selection of studies required: a patient cohort without tip placement guidance technology; a documented landmark technique to place catheter tips; data documenting initial catheter placement and, that the lower third of the SVC and the cavo-atrial junction (CAJ) were included in the placement criteria. With few exceptions, articles written between 1993 and 2009 met the stated selection criteria. A composite of outcomes associated with tip placement was analyzed, and an overall percent proficiency of accurate catheter tip placement calculated. Results: Nine studies in eight articles met the selection criteria and were included for analysis. Rates of first placement success per study ranged from 39% to 75%, with the majority (7/9) being single center studies. The combined overall proficiency of these studies calculated as a weighted average was 45.87%.

Abstract Objective To determine the efficacy of unfractionated heparin in reducing central venous catheter-related deep venous thrombosis and/or catheter thrombotic occlusion in children by systematically searching the literature and conducting a meta-analysis study. Methods Four electronic databases (PubMed, Google Scholar, Elsevier’s thrombosis journal, and the Cochrane Central Register for Controlled Trials) were searched for journal peer-reviewed articles published in the period from Jan 2000 to Dec 2018. The search criteria included observational studies, and randomized controlled trials on patients aged 0–18 years with central venous catheters (CVC), which compare between the effect of UFH (flushes, lock solutions, continuous infusion, and heparin bonded catheter) and no prophylaxis (Normal saline flush or no treatment) for the prevention of CVC thrombotic complications (CVC-related deep venous thrombosis (DVT) and/or catheter thrombotic occlusion). Two authors independently reviewed and identified the eligible studies, which were assessed for study methodology including bias, and extraction of unadjusted data whenever available. To pool data from eligible studies, the meta-analysis was performed on RevMan version 5.3. Odds ratios were generated with the corresponding 95% CI through the random-effect model. Results Of the 413 articles identified, only eight studies were eligible with 1380 patients. Our results revealed that UFH was significantly superior on control group in reducing thrombotic occlusion and/or CVC-related DVT (odds ratio 0.39, 95% CI: 0.19:0.8) (p 0.01). Conclusion The published data support the hypothesis that using UFH as a thromboprophylaxis may significantly reduce catheter thrombotic complication in pediatric patients with CVC.
