Common Risk Factors

Central venous catheters (CVC) are used in many clinical settings for a variety of indications. We performed a systematic literature review concerning case reports of retained calcified fibrin sheaths after dialysis CVC removal. The aim of our study was to systematize the knowledge regarding clinical management of this phenomenon, placing special emphasis on diagnostic radiological features in different imaging modalities, including chest radiography, echocardiography, computed tomography, and magnetic resonance imaging. We discuss the most common risk factors associated with this CVC complication. In our review, we found eight cases of hemodialysis patients. The most common risk factors associated with calcified fibrin sheath formation in the analyzed cases were pro-thrombotic and pro-calcification factors related to patient comorbidities, and prolonged catheter dwell time. Differentiating between a calcified fibrin sheath (present in about 6% of patients with long-term indwelling CVC as diagnosed by computed tomography) and a retained catheter tip can be challenging. The initial diagnosis based on imaging methods was incorrect in most of the analyzed cases. This suggests that some cases of retained fibrin sheaths may remain undetected or misinterpreted. This is important in patients with known pro-thrombotic and pro-calcification risk factors and prolonged catheter dwell time. Therefore, implementation of preventive strategies, familiarity with radiological findings of this phenomenon, comparison with previous imaging studies, and an overall comprehensive assessment with clinical data is imperative.

Heparin Lock

Abstract Traditionally, heparin-lock solution has been used with all central venous catheters. The introduction of new technology calling for the elimination of heparin and the growing concerns about the use of heparin have caused many health care professionals to question its continued use for this purpose. This literature review attempts to answer the most common questions using available research; however, there continues to be more questions than answers. At present, it appears that some farm of anticoagulant will produce more patent catheters, and heparin-lock solution is the only product commercially available. This situation drives the need for a careful assessment of patients' needs prior to abandoning the use of heparin.

Objetivo: Analizar las producciones científicas que abordan las estrategias de prevención y atención en la obstrucción de los catéteres venosos centrales totalmente implantados en pacientes con cáncer.Material y método: Esta es una revisión bibliográfica integradora, que se realizó en las bases de datos MEDLINE, LILACS, CINAHL y EMBASE, del 20 de julio de 2019 al 31 de julio de 2019, utilizando los siguientes descriptores: Cateterización venosa central; Obstrucción del catéter y oncología, más el uso de términos libres: catéter completamente implantado y neoplasia.Resultados: En total, se seleccionaron e incluyeron 10 estudios. Después del análisis, surgieron las siguientes categorías de análisis: Estrategias para prevenir la obstrucción en CVC-TI y Atención establecidas en el despacho de CVC-TI; teniendo como principales temas abordados: la comparación entre la eficacia en el uso de heparina y solución salina para el mantenimiento y el intervalo de tiempo entre ellos; métodos de despacho y evaluación de permeabilidad CVC-IT.Conclusión: A pesar de la aparición de nuevas formas posibles de prevención de obstrucciones y estrategias de atención en la eliminación de CVC-IT, la literatura no presenta consenso sobre el uso de soluciones con o sin heparina y el intervalo de tiempo entre el mantenimiento para la efectividad de permeabilidad de estos dispositivos en pacientes con cáncer. Objective: To analyze scientific productions that address prevention and care strategies in the obstruction of central venous catheters that are fully implanted in cancer patients.Material and Method: This is an integrative literature review, which took place on the MEDLINE, LILACS, CINAHL and EMBASE databases, from 20 July 2019 to 31 July 2019, using as descriptors: Central venous catheterization; Catheter obstruction and Oncology, in addition to the use of free terms: Catheter fully implanted and Neoplasia.Results: In total, 10 studies were selected and included. After the analysis, the following analysis categories emerged: Strategies for preventing obstruction in CVC-TI and Care established in clearing the CVC-TI; having as main subjects approached: the comparison between the effectiveness in the use of heparin and saline solution for maintenance and time interval between them; unblocking methods and permeability assessment of CVC-TI.Conclusion: Despite the emergence of new possible ways of preventing obstruction and care strategies for clearing CVC-TI, the literature does not have a consensus on the use of solutions with or without heparin and the time interval between maintenance for the effectiveness of the permeability of these devices in cancer patients.

Two-dimensional echocardiograms were used to prospectively screen 49 patients with 56 central venous catheters for right atrial thromboses from October 1985 to May 1986. All but four patients received a two-dimensional echocardiogram prior to insertion of the catheter. Once the catheters were in place, two-dimensional echocardiograms were performed no later than 3 weeks after insertion and then every 14 days until the catheter was removed. A single thrombus was detected 79 days after catheter placement (an incidence of 1.8%). Previous recommendations for weekly screening with two-dimensional echocardiogram were based on case reports alone. The 95% confidence limits for a negative two-dimensional echocardiogram result suggest that the initial two-dimensional echocardiogram screen for thrombus be obtained no sooner than 3 weeks after catheter insertion. In addition, significant gastrointestinal disease requiring operative intervention was present in 10 of 11 previous case reports as well as in our patient. Further studies with larger sample sizes are needed to determine whether subgroups of infants exist who are at a relatively higher risk for right atrial thrombus formation.
