Vascular access

The incidence of central venous catheter (CVC)-related bloodstream infections is high in patients requiring a long-term CVC. Therefore, infection prevention is of the utmost importance. The aim of this study was to provide an updated overview of randomized controlled trials (RCTs) comparing the efficacy of taurolidine containing lock solutions (TL) to other lock solutions for the prevention of CVC-related bloodstream infections in all patient populations. On 15th February 2021, PubMed, Embase and The Cochrane Library were searched for RCTs comparing the efficacy of TLs for the prevention of CVC-related bloodstream infections with other lock solutions...

BACKGROUND: Applicability of totally implantable venous access port (TIVAP) and peripherally inserted central venous catheter (PICC) in non-hematological malignancies patients remains controversial. METHODS: A systematic studies search in the public databases PubMed, EMBASE, Wan Fang, CNKI (China National Knowledge Infrastructure), the Cochrane Library and Google Scholar (updated to May 1, 2020) was performed to identify eligible researches. All statistical tests in this meta-analysis were performed using Stata 12...

Symptomatic catheter related thrombosis (CRT) occurs in 4%-8% of cancer patients. The mean incidence of CRT, detected either by echography or Doppler ranges between 12 and 14% with a high negative predictive value of about 95%, allowing the subsequent occurrence of CRT (symptomatic and asymptomatic) to be safely excluded. Despite its frequency and its medico-economic consequences, no thromboprophylaxis has been validated to date. In most patients, CRT occurs immediately after catheter insertion, most often within the first week and almost all within the first month after insertion...

Standard treatment of catheter-associated upper extremity deep vein thrombosis (UE-DVT) is anticoagulation, although catheters are often removed for this indication. The optimal time for catheter removal and whether the act and/or timing of catheter removal is associated with pulmonary embolism (PE) remain unknown. A retrospective cohort study was performed at 8 participating institutions through the Venous thromboEmbolism Network US. Patients with hematologic malignancies and central venous catheter (CVC)-associated UE-DVT were included from 1 January 2010 through 31 December 2016...

BACKGROUND: The Michigan Risk Score (MRS) was the only predicted score for peripherally inserted central venous catheters (PICC) associated upper extremity venous thrombosis (UEVT). Age-adjusted D-dimer increased the efficiency for UEVT. There were no external validations in an independent cohort. METHOD: A retrospective study of adult patients with PICC insertion was performed. The primary objective was to evaluate the performance of the MRS and age-adjusted D-dimer in estimating risk of PICC-related symptomatic UEVT...

BACKGROUND: The purpose of this study is to elucidate the association between peripherally inserted central venous catheter (PICC) in upper extremities and lower extremity deep venous thrombosis (LEDVT) by observing the changes in D-dimer. METHODS: This was a retrospective cohort study with 3452 patients (104 inserted with PICCs and 3348 without PICC) enrolled at the neurology department from April 1, 2017 to April 1, 2020. The patients underwent color Doppler ultrasound (CDU) and D-dimer examinations...

BACKGROUND: The Michigan Appropriateness Guide for Intravenous Catheters (MAGIC) provides evidence-based criteria for peripherally inserted central catheter (PICC) use. Whether implementing MAGIC improves PICC appropriateness and reduces complications is unknown. METHODS: A quasiexperimental study design to implement MAGIC in 52 Michigan hospitals was used. Data were collected from medical records by trained abstractors. Hospital performance on three appropriateness criteria was measured: short-term PICC use (≤5 days), use of multilumen PICCs and PICC placement in patients with chronic kidney disease...

PURPOSE: There is no concrete evidence to support the association between the amount of subcutaneous fat area (SFA) in the central venous port-insertion site (precordium) and port-related complications. We aimed to investigate the relationship between SFA in the midclavicular line and postoperative infectious complications in patients undergoing port-insertion surgery. METHODS: This was a single-institute and historical cohort study of 174 patients who underwent first central venous port implantation surgery for chemotherapy between January 2014 and December 2018...

PURPOSE: Vascular access patterns in the intensive care unit (ICU) have shifted from non-tunneled central venous catheters (CVCs) towards peripherally inserted central catheters (PICCs). We evaluated perceptions of critical care practitioners regarding these devices and variation in evidence-based practice. MATERIALS: A 35-question survey on ICU vascular access was deployed in 13 Michigan hospitals. Descriptive statistics summarized responses. Differences in utilization, perceptions and evidence-based practices between PICCs and CVCs, by participant and site-level characteristics, were assessed...

OBJECTIVE. Coupled ECG-electromagnetic (EM) guidance shows promise for use in placement of peripherally inserted central catheters (PICCs) when compared with the classic blind technique. However, ECG-EM guidance has not been appropriately compared with the reference standard of fluoroscopy (FX) guidance. Here, we aimed to compare ECG-EM guidance with FX guidance with regard to the final tip position of PICCs. SUBJECTS AND METHODS. A total of 120 patients (age range, 19-94 years) referred for PICC placement were randomized to the ECG-EM or FX group...

PURPOSE: There was no optimal risk assessment tool to stratify the risk of peripherally inserted central catheter-related venous thromboembolism (PICC-RVT) in cancer patients. We currently use the Caprini risk assessment model for thrombotic risk assessment, but no evidence exists on the effectiveness of Caprini in such patients. This study was to assess the validity of the Caprini in Chinese cancer patients with PICCs. METHODS: We conducted a prospective study of 468 participants...

Choosing the appropriate vascular access device is a pivotal step to guarantee vessel health and preservation in cancer patients. The first turning point is the determination of the need for central venous catheters (CVCs) followed by the selection of the CVC that will complete the prescribed treatment while minimizing complications and satisfying patients' needs and expectations. Peripherally inserted central catheters (PICCs) have steadily grown over the years as an alternative to centrally inserted central catheters and totally implantable catheters based on several advantages including avoidance of placement-associated mechanical complications, easier transitions from hospital to intermediate care settings and home, but also increase in healthcare expenditure, supportive reimbursement policies, and ability to train existing staff...

AIM: The use of heparin and 0.9% saline solution is always controversial for central venous catheters. However, there is no systematic review or guideline about whether saline solution can replace heparin solution in adult cancer patients with totally implantable venous access ports (TIVAPs). The purpose of this review is to evaluate whether saline solution can replace heparin saline to lock TIVAPs. METHODS: The following databases were searched: PubMed, the Cochrane Library, Web of Science, Embase, CINAHL and Ovid (January 1, 1982, and February 21, 2020)...

Totally implantable venous access devices (TIVADs) are frequently used for the administration of chemotherapy or parenteral nutrition and have proved to be safe and improve patient quality of life during treatment. Catheter-related infections are the most common complication, whereas catheter fracture and embolization is rarely seen. We present a case of a 61-year-old cancer patient in which the TIVAD fractured and embolized to the patient's left knee 18 months after its initial placement. An endovascular procedure with intraoperative imaging revealed that the catheter had embolized to the popliteal artery and was successfully removed, the only explanation being the presence of an atrial septal defect...

BACKGROUND: Vasopressors are conventionally administered through a central venous catheter (CVC) and not through a peripheral venous catheter (PVC) since the latter is believed to be associated with increased risk of extravasation. Placement of a CVC requires suitably trained personnel to be on hand, and in resource-limited settings, this requirement may delay placement. Because of this and in cases where suitably trained personnel are not immediately available, some clinicians may be prompted to utilise a PVC for infusing vasopressors...

Establishment of long-term central venous access imposes the risk of procedural adverse events (air embolism, pneumothorax, accidental arterial cannulation of the great vessels, tricuspid valve damage and cardiac tamponade) as well as the risk of increased morbidity and mortality due to catheter related blood stream infections, vessel stenosis, deep vein thrombosis and the often high risk anaesthetic management of syndromic children. This narrative review aims to provide a historical and clinical background for the development and use of CVADs (central venous access devices), origin and management of the most common complications (catheter related thrombosis, infections and persistent withdrawal occlusion) and present the reader with an update on the "why, what, where, who and how" in paediatric long-term central venous access...

A frequent complication of central venous port systems (CVP) is infection (CVP-I), either local (CVP-LI) or a life-threatening blood stream infection (CVP-BSI). We examined the course of CVP-I including results of an antibiotic eradication attempt of CVP-BSI. We investigated adults with CVP-I from 2010 to 2018 who had to undergo port explantation or were treated by a combination of systemic antibiotics and antibiotic lock therapy (ALT). In nine years we diagnosed 206 CVP-I (CVP-LI: 52; CVP-BSI: 152). In 146 patients with CVP-I the port system was primary explanted, while 56 patients received antibiotics/ALT...

Objectives: Central venous access is needed to facilitate chemotherapy for many cancer patients. Central venous catheter-related thrombosis (CVCT) is a major complication that can cause significant morbidity and mortality. We sought to explore the rate of CVCT in a general cancer population in Australia and to identify factors associated with increased risk of thrombosis. Design: This is a multi-centre retrospective cohort study. Setting and participants: We analysed key patient, treatment, and cancer-related factors for 317 patients with cancer and central venous catheters inserted for systemic therapy...

OBJECTIVE: Early replacement of a new central venous catheter (CVC) may pose a risk of persistent or recurrent infection in patients with a catheter-related bloodstream infection (CRBSI). We evaluated the clinical impact of early CVC reinsertion after catheter removal in patients with CRBSIs. METHODS: We conducted a retrospective chart review of adult patients with confirmed CRBSIs in 2 tertiary-care hospitals over a 7-year period. RESULTS: To treat their infections, 316 patients with CRBSIs underwent CVC removal...
