Fibrin sheath

INTRODUCTION: Rice bodies (RBs) are pale and glossy appearing small fibrinous nodules that form due to synovial or tenosynovial joint inflammation. RBs are significant as they are common in orthopedic practices causing nonspecific symptoms such as pain, swelling, range of motion limitations, crepitus, and catching sensations. These loose bodies occur often within the bursa as a symptom of chronic bursitis and are commonly associated with rheumatoid, inflammatory, or tuberculous arthritis...

INTRODUCTION: Stuck tunneled central venous catheters (CVCs) have been increasingly reported. In rare cases, the impossibility of extracting the CVC from the central vein after regular traction is the result of rigid adhesions to the surrounding fibrin sheath. Forced traction during catheter removal can cause serious complications, including cardiac tamponade, hemothorax, and hemorrhagic shock. Knowledge and experience on how to properly manage the stuck catheter are still limited. CASE PRESENTATION: Here, we present two cases that highlight the successful removal of the stuck tunneled CVC via thoracotomy through the close collaboration of multidisciplinary specialists in the best possible way...

The prevalence of central venous catheters (CVC) in hemodialysis patients is around 20-30%. In this scenario, complications related to the use of the CVC are commonly observed, requiring active management by nephrologists. These include infectious complications as well as those related to CVC malfunction. Among the latter, the formation of a fibrin sheath around the catheter linked to foreign body reaction could cause CVC malfunction in various ways. Even after the removal of the catheter, the fibrin sheath can remain inside the vascular lumen (ghost fibrin sheath) and rarely undergo calcification...

OBJECTIVE: Port-a-caths are implanted intravascular chest ports that enable venous access. With more port placements performed by interventional radiologists, it is important to discern differences in infection and complication rates between double- and single-lumen ports. METHODS: We retrospectively reviewed 1,385 port placements over 2 years at the University of Miami. Patients were grouped by single- or double-lumen ports. Data on duration of catheter stay, bloodstream infections, malfunctions, and other complications (fibrin sheath, thrombosis, catheter malposition) were collected...

PURPOSE: To report the safety and effectiveness of fibrin sheath stripping of pediatric chest ports. MATERIALS AND METHODS: Fibrin sheath stripping procedures for pediatric chest ports between 2018 and 2023 were retrospectively reviewed. The treatment indication was the inability to aspirate blood from the port. The technical success, adverse events, days of primary service interval, days of secondary service interval, fluoroscopy time, and fluoroscopy dose were recorded...

OBJECTIVE: Tunneled-cuffed catheters (TCCs) are frequently used for establishing hemodialysis access for maintenance hemodialysis in older patients with exhausted resources of peripheral vessels. Fibrin sheath formation around the catheter is one of the most common complications of long-term use of indwelling catheter, which may cause the malfunction of the catheter. In this study, we intend to compare the prognosis of two catheter replacement methods, in situ replacement and replacement through a fibrin sheath crevice, with both being assisted by balloon dilation, and to explore the optimal catheter replacement process...

Fibrin sheath formation is a leading culprit of central venous catheter malfunction. The complete removal of fibrin sheaths is an essential component of maintaining catheter patency, preventing future restenosis, and decreasing the risk of bloodborne infections. Treatment of fibrin sheaths includes pharmacologic therapy, balloon angioplasty, catheter exchange, and mechanical stripping. In this article 3 cases are reviewed, 2 patients had long-term hemodialysis catheter malfunction and 1 had complications related to a chest port...

UNLABELLED: The majority of patients receiving chemotherapy undergo PICC catheterization. However, PICCs are significantly associated with catheter related complications, including deep vein thrombosis, blood infection, fibrin sheath, catheter prolapse, catheter displacement and blockage. Of all the risks, PICC-related VT was the most prevailing clinic symptom and resulted in a high risk of death. AIM: The study aimed to investigate the preventive efficacy and safety of aspirin for patients with malignant tumors receiving venous thrombosis (VT) related with peripherally inserted central catheters (PICC) treatment...

BACKGROUND: To determine the feasibility and safety of ultrasound-guided totally implantable venous access port (TIVAP) implantation via the posterior approach of the internal jugular vein (IJV). METHODS: From September 2021 to August 2022, 88 oncology patients underwent ultrasound-guided implantation of TIVAPs via the posterior approach of the IJV for the administration of chemotherapy. The catheter tip was adjusted to be positioned at the cavoatrial junction under fluoroscopic guidance...

BACKGROUND: Parastomal evisceration represents a preventable surgical complication that should not occur with appropriate technical diligence and surgical skills. While late parastomal hernias are well described in the literature, there is a paucity of reports on the early postoperative occurrence of parastomal intestinal evisceration. CASE PRESENTATION: An urgent laparotomy was performed on a 58-year-old female patient for an acute cecal perforation with generalized peritonitis related to underlying colon cancer...

BACKGROUND: Tunneled catheters are effectively used in patients receiving chronic dialysis due to end-stage renal disease. However, the dysfunction of catheters caused by infection or thrombus requires repetitive procedures. In this study, we aimed to compare the long-term results of heparin-coated and non-heparin-coated tunneled dialysis catheters. METHOD: The study included a total of 161 patients who underwent tunneled dialysis catheter placement. Heparin-coated and non-heparin-coated tunneled catheters were placed in 81 and 80 patients, respectively...

BACKGROUND: The subxiphoid pericardial access is technically difficult and has a considerable rate of complications, thus transatrial access may be an alternative. OBJECTIVES: This study sought to assess the feasibility and safety of this strategy regarding periprocedural period and after 1-week follow-up. METHODS: The investigators performed epicardial mapping through transatrial puncture in 20 swine. Animals were divided into group A, in which aspiration of the sheath was performed to maintain negative pressure after the withdraw of the catheters, and group B, in which a device (Konar-MF VSD Occluder) was delivered to occlude the right atrial appendage perforation...

OBJECTIVE: The aim of this study was to evaluate the causes of the dysfunctional tunneled cuffed catheters (TCCs) using multi-spiral computed tomography venography (MSCTV), and to analyze the outcomes of endovascular salvage techniques. MATERIAL AND METHODS: This retrospective review data from 27 patients who experienced TCC dysfunction between July 1, 2016 and January 31, 2021 was conducted. Patients' demographic data, clinical signs and symptoms, and imaging data were collected from interventional radiology database...

Patients with end-stage renal disease (ESRD) receive dialysis through either hemodialysis (HD) or peritoneal dialysis (PD). HD has challenges associated with vascular access and catheter-associated complications. The development of a fibrin sheath is a common complication with tunneled catheters. However, infection of the fibrin sheath is not usually encountered. We discuss the case of a 60-year-old female with ESRD and heart failure with reduced ejection fraction (HFrEF) receiving HD via tunneled right internal jugular (RIJ) Permcath who was diagnosed with an infected fibrin sheath located in the cavoatrial junction via a transesophageal echocardiogram (TEE)...

OBJECTIVE: To assess the efficacy and safety of dual ultrasound-guided (DUG) totally implantable venous access port (TIVAP) implantation (namely, using ultrasound-guided percutaneous puncture with transesophageal echocardiography-guided catheterization) via the right internal jugular vein (IJV) in pediatric patients with cancer. METHODS: Fifty-five children with cancer requiring chemotherapy underwent DUG-TIVAP implantation via the right IJV. Clinical data were recorded, including the procedure success rate, first attempt success rate, and perioperative and postoperative complications...
