In this study, silver/copper (Ag/Cu)-coated catheters were investigated for their efficacy in preventing methicillin-resistant Staphylococcus aureus (MRSA) infection in vitro and in vivo Ag and Cu were sputtered (67/33% atomic ratio) on polyurethane catheters by direct-current magnetron sputtering. In vitro, Ag/Cu-coated and uncoated catheters were immersed in phosphate-buffered saline (PBS) or rat plasma and exposed to MRSA ATCC 43300 at 10(4) to 10(8) CFU/ml. In vivo, Ag/Cu-coated and uncoated catheters were placed in the jugular vein of rats...

INTRODUCTION: Peripherally inserted central catheters (PICCs) are a popular alternative to central venous lines. PICCs can provide reliable long-term access for intravenous fluids, antibiotics and total parenteral nutrition. Multiple factors can contribute to difficult PICC removal including adherent fibrin and thrombus formation around the catheter. We discuss a novel endovascular retrieval technique to remove tightly adherent PICCs. CASE PRESENTATION: A 42-year-old male with history of chronic pancreatitis requiring intravenous pain medications, presented with right upper extremity single lumen PICC that could not be removed by standard techniques...

OBJECTIVE: This study aimed to examine the influence of oral acetylsalicylic acid on blood fluidity and infusion speed in the cancer patients with Peripherally Inserted Central Catheter (PICC). BACKGROUND: PICC is placed for prolonged chemotherapy of cancer patients. The fibrin sheaths, which consist of cellular substance and non-cellular substance, generate at the place of insertion and grow down all over the catheter. Finally they cover the vent of the catheter and lead to catheter dysfunctions such as the decrease of infusion speed...

With the increased use of implanted venous access devices (IVADs) for continuous long-term venous access, several techniques such as percutaneous endovascular fibrin sheath removal, have been described, to maintain catheter function. Most standard techniques do not capture the stripped fibrin sheath, which is subsequently released in the pulmonary circulation and may lead to symptomatic pulmonary embolism. The presented case describes an endovascular technique which includes stripping, capture, and removal of fibrin sheath using a novel filter device...

Central venous catheters (CVCs) are essential in the management of hemodialysis patients, but they also carry unintended negative consequences and in particular thrombosis and infection, adversely affecting patient morbidity and mortality. This review will focus on the etiology, prevention, and management of CVC-related dysfunction, which is mainly associated with inadequate blood flow. CVC dysfunction is a major cause of inadequate depuration. Thrombus, intraluminal and extrinsic, as well as fibrous connective tissue sheath (traditionally indicated as fibrin sheath) formation play a central role in establishing CVC dysfunction...

BACKGROUND: Due to their unique properties, adipose derived stem cells (ADSCs) obtain promising potential to enhance nerve regeneration. The aim of this study was to investigate if fibrin-glue embedded ADSCs were a beneficial adjunct to primary coaptation in a rat sciatic nerve model. MATERIALS AND METHODS: Fifty male Lewis rats underwent sciatic nerve transection and subsequent epineural suture repair. The treatment group received ADSCs re-suspended in fibrin glue, while the control group received fibrin glue only...

Long-term hemodialysis catheter dwell time in the central vein predisposes to fibrin sheath development, which subsequently causes catheter malfunction or occlusion. In very rare cases, the catheter can be overgrown with fibrin and rigidly connected with the vein or heart structures. This makes its removal almost impossible and dangerous because of the possibility of serious complications, namely vein and heart wall perforation, bleeding, or catheter abruption in deep tissues. We describe two cases in which standard retrieval of long-term catheters was not possible...

Microfluidic devices create precisely controlled reactive blood flows and typically involve: (i) validated anticoagulation/pharmacology protocols, (ii) defined reactive surfaces, (iii) defined flow-transport regimes, and (iv) optical imaging. An 8-channel device can be run at constant flow rate or constant pressure drop for blood perfusion over a patterned collagen, collagen/kaolin, or collagen/tissue factor (TF) to measure platelet, thrombin, and fibrin dynamics during clot growth. A membrane-flow device delivers a constant flux of platelet agonists or coagulation enzymes into flowing blood...

The superior vena cava (SVC) is the largest central systemic vein in the mediastinum. Imaging (ie, radiography, computed tomography [CT], magnetic resonance [MR] venography, and conventional venography) plays an important role in identifying congenital variants and pathologic conditions that affect the SVC. Knowledge of the basic embryology and anatomy of the SVC and techniques for CT, MR imaging, and conventional venography are pivotal to accurate diagnosis and clinical decision making. Congenital anomalies such as persistent left SVC, partial anomalous pulmonary venous return, and aneurysm are asymptomatic and may be discovered incidentally in patients undergoing imaging evaluation for associated cardiac abnormalities or other indications...

UNLABELLED: Adipose tissue-derived mesenchymal stem cells (AdMSCs) are useful in the regeneration of neural tissues. Furthermore, xenotransplantation of human adipose tissue-derived mesenchymal stem cells (hAdMSCs) into animal models has already been tested and the results encouraged us to study peripheral nerve regeneration in rabbits, in order to test the feasibility of a xenotransplantation of hAdMSCs. ANIMALS AND METHOD: To promote end-to-end nerve fiber contacts of a 4-cm gap in the peroneal nerve of white New Zealand rabbits, an autologous vein conduit was used and three groups of animals were evaluated...

We present a 6-year-old girl with acute lymphoblastic leukemia who demonstrated on chest X-ray a radiopacity in the superior vena cava after removal of an implanted venous access device. This radiopacity was initially thought to be a retained catheter fragment. On review of previous imaging, we were able to document the temporal development of a calcified catheter cast as distinct from the catheter. This case represents a rare consequence of central venous catheterization in children. Knowledge of this finding as a possible complication may help avoid performance of unnecessary follow-up imaging or invasive procedures...

Inflammation is a natural phase of the wound healing response, which can be harnessed for the in situ tissue engineering of small-diameter blood vessels using instructive, bioresorbable synthetic grafts. This process is dependent on colonization of the graft by host circulating cells and subsequent matrix formation. Typically, vascular regeneration in small animals is governed by transanastomotic cell ingrowth. However, this process is very rare in humans and hence less relevant for clinical translation. Therefore, a novel rat model was developed, in which cell ingrowth from the adjacent tissue is inhibited using Gore-Tex sheathing...

Removal of a tunneled cuffed central venous catheter can be challenging and risky. In some cases, the catheter firmly adheres to the surrounding tissues, becoming an integrated part of the vessel wall. We present the case of an adult female hemodialysis (HD) patient with a dysfunctioning HD tunneled cuffed catheter. The catheter removal procedure proved mazy. After several attempts, the catheter was removed together with the peri-catheter fibrin sheath. However, the post-procedure period was uneventful.

BACKGROUND/PURPOSE: A fibrin sheath is a circumferential sleeve of endothelium that forms around the surface of implanted central venous catheters and frequently remains intact within the lumen of the vein after removal of the catheters. We describe a new entity of infective endovascular fibrin sheath vegetations. METHODS: Records of patients hospitalized and found to have echocardiographically identified infective endovascular fibrin sheath vegetations at our institution, Cedars Sinai Medical Center, from 2010 to 2014 were reviewed for clinical variables of interest...

BACKGROUND: Peritoneal dialysis catheter (PDC) dysfunction can often be treated fluoroscopically by manipulation with wire, balloon or stiff stylet, saving surgical intervention for refractory cases. We describe an enhanced percutaneous approach to PDC salvage that can lead to a more definitive intervention and salvage for cases refractory to fluoroscopic manipulation. METHODS: In five cases of PD catheter malfunction, the deep cuff was dissected free after a 0...

BACKGROUND: Catheter-related bloodstream infections (CRBSIs) and catheter-related thrombosis (CRT) are common complications of central venous catheters (CVC), which are used to monitor patient health and deliver medications. CVCs are subject to protein adsorption and platelet adhesion as well as colonization by the natural skin flora (i.e. Staphylococcus aureus and Staphylococcus epidermidis). Antimicrobial and antithrombotic drugs can prevent infections and thrombosis-related complications, but have associated resistance and safety risks...

Removal of tunnelled central venous catheters can become complex if left in situ for a prolonged period. We report a challenging case of a stuck tunnelled haemodialysis catheter, which required sternotomy with cardio-pulmonary bypass for retrieval. A 47-year-old female had failed attempts to remove the venous limb of a Tessio line on the ward. A cut down on the internal jugular vein and division of the fibrin sheath failed to release it. Synchronous traction was applied via a snare inserted through a femoral approach...
