Central Vascular access

Mariusz Kusztal, Krzysztof Nowak
For arrhythmia treatment or sudden cardiac death prevention in hemodialysis patients, there is a frequent need for placement of a cardiac implantable electronic device (pacemaker, implantable cardioverter defibrillator, or cardiac resynchronization device). Leads from a cardiac implantable electronic device can cause central vein stenosis and carry the risk of tricuspid regurgitation or contribute to infective endocarditis. In patients with end-stage kidney disease requiring vascular access and cardiac implantable electronic device, the best strategy is to create an arteriovenous fistula on the contralateral upper limb for a cardiac implantable electronic device and avoidance of central vein catheter...

Chronic kidney disease requires life-long renal replacement therapy, which can greatly impair the quality of life (QOL) of patients. This cross-sectional study aimed to assess the QOL of patients on haemodialysis, and the factors affecting it, at the dialysis unit of Basra General Hospital. A total of 104 patients with end-stage renal disease on haemodialysis were included. Data were collected using the World Health Organization QOL questionnaire. Sociodemographic and clinical data were also collected. Of the 104 patients, 57% were male, 73% were older than 45 years, 87% were of middle and low socioeconomic status, 70% had been on dialysis for more than 1 year, 74% had arteriovenous fistula vascular access, 34% had diabetes and 48% were positive for hepatitis virus...

PURPOSE: Patients admitted to cardiac intensive care unit need administration of drugs intravenously often in concomitance of therapeutic techniques such as non-invasive ventilation, continuous renal replacement therapy and intra-aortic balloon counterpulsation. Therefore, the insertion of central venous catheters provides a reliable access for delivering medications, laboratory testing and hemodynamic monitoring, but it is associated with the risk of important complications. In our study, we tested the efficacy and safety of peripherally inserted central catheters to manage cardiac intensive care...

Endothelial cells of the central nervous system over-express surface proteins during neurological disorders, either as a cause, or a consequence, of the disease. Since the cerebral vasculature is easily accessible by large contrast-carrying particles, it constitutes a target of choice for molecular magnetic resonance imaging (MRI). In this review, we highlight the most recent advances in molecular MRI of brain endothelial activation and focus on the development of micro-sized particles of iron oxide (MPIO) targeting adhesion molecules including intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), P-Selectin and E-Selectin...

Guidelines recommend using single-lumen central vascular access devices (CVADs) for the administration of parenteral nutrition (PN) or lipid-based solutions, or a dedicated lumen on a multilumen CVAD. Publications reviewed by the authors reported comparative rates of catheter-related bloodstream infection (CR-BSI) in patients with CVADs who received PN through a dedicated lumen compared with those who had PN administered through multilumen CVADs. Two studies included 650 patients with 1349 CVADs. CR-BSIs were equally distributed between the 2 groups...

Exhausted vasculature is not uncommon in patients receiving long-term hemodialysis treatment. Certain patients exhaust their peripheral veins and do not retain the venous capital necessary for fistula creation. Others suffer from severe peripheral arterial disease and despite the presence of adequate venous capital are not able to receive an arteriovenous access successfully. Most importantly, in the case of occluded central veins, the creation of an arteriovenous access in the arms or thighs would be futile, even if peripheral veins and/or arteries were available...

BACKGROUND: Paracetamol (acetaminophen) is the most widely used non-prescription analgesic in the world. Paracetamol is commonly taken in overdose either deliberately or unintentionally. In high-income countries, paracetamol toxicity is a common cause of acute liver injury. There are various interventions to treat paracetamol poisoning, depending on the clinical status of the person. These interventions include inhibiting the absorption of paracetamol from the gastrointestinal tract (decontamination), removal of paracetamol from the vascular system, and antidotes to prevent the formation of, or to detoxify, metabolites...

BACKGROUND AND IMPORTANCE: Cavernous malformations (CMs) are vascular abnormalities with a hemorrhage risk of 0.2% to 5% per year, according to their location. Brainstem CMs seem to have a greater hemorrhagic risk and represent a neurosurgical challenge. We report here the first transsylvian transuncal (TS-TU) approach for an anteromedial mesencephalic CM resection. CLINICAL PRESENTATION: A 29-yr-old female suddenly presented a left hemiparesis and central facial paresis with a diplopia in the upward gaze...

Therapeutic plasma exchange is an apheresis modality in which plasma is separated from the blood cellular components ex vivo, discarded, and replaced with an isosmotic fluid (most commonly 5% albumin) to maintain appropriate oncotic pressure in the patient. Therapeutic plasma exchange is used in the treatment of many diseases and indications. The recent seventh edition of the American Society for Apheresis guidelines indicates approximately 72 diseases and 116 indications for which therapeutic plasma exchange may be effective...

Central venous access has become invaluable in the treatment of patients with a wide array of acute and chronic disease entities. Central venous catheters provide durable, short-term and long-term access solutions while saving the patient from repeated peripheral needle sticks. Central venous catheters include: non-tunneled central venous catheters, tunneled central venous catheters, and port catheters. Typically, the placement of a central venous catheter is performed by Vascular and Interventional Radiologists...

Implantable vascular access devices are frequently used in patients who have poor peripheral venous access. These devices can be partially implanted as tunneled and nontunneled central catheters, or they can be fully implanted as ports. Compared with long-term catheters, implanted ports have lower infection rates and improved perceptions of quality of life, but complications still occur in 2% to 18% of patients, frequently requiring removal of the device. Since the conception of implantable vascular access device ports, numerous advances in port design, materials, and techniques for implantation and care have been developed with the goal of overcoming frequent complications...

Extracorporeal photopheresis is an immunomodulatory therapy indicated for patients with cutaneous T-cell lymphoma, graft-versus-host disease, and heart or lung allograft rejection. Whole blood from the patient is drawn into the photopheresis instrument where it is separated into its components. Plasma, red blood cells, and the treated buffy coat are subsequently returned to the patient. Consistent, adequate blood flow is necessary to successfully complete the procedure. Vascular access options for photopheresis include peripheral vein cannulation, tunneled central venous catheters, and subcutaneous ports...

Surgery for craniopharyngiomas can be challenging due to the involvement of multiple critical neurovascular structures. The expanded endoscopic endonasal approach can provide superior access to suprasellar craniopharyngiomas, particularly with retrochiasmatic extension and significant hypothalamic involvement. We describe the surgical technique used to treat a 30-year-old patient who presented with 4 weeks of worsening vision, fatigue, and memory loss. His vision was counting fingers at 1 feet on the right and 20/800 on the left with a temporal hemianopsia...

Background: The modality by which haemodialysis (HD) is delivered [arteriovenous fistula (AVF), arteriovenous graft (AVG) or central venous catheter (CVC)] varies widely and is influenced by clinical evidence, patient factors and the prevailing service configuration. The aim of this study was to determine the outcome and impact of access strategy on patient outcome by mapping out the HD journey in a cohort of incident patients. Methods: A 2-year cohort of consecutive incident HD patients from the point of referral for first dialysis access to completion of the first 365 days of HD was prospectively reviewed...
