Background:Catheter-related thrombotic complications(TCs) can occur during the long term use of a chronic dialysis catheter (CDC), including fibrin sheath (FS), mural thrombosis (MT), venous thrombosis (VT), and intraluminal clots (IC), which has not been reported with MRI. The aim of our study was to evaluate the determination of catheter tip position (TP) and resolution of TCs in patients with transjugular CDC scheduled into the superior vena cava using high resolution magnetic resonance cholangiopancreatography (HR-MRCP) and T2-weighted imaging (HR-T2WI).Methods:The study protocol was approved by the local Research Ethics Committee. Informed consent was obtained from all patients. In total, 41 consecutively enrolled transjugular CDC patients with suspected catheter dysfunction were scanned with HRMRCP and HR-T2WI. The distance from the top to the tip of the catheter and the presence and nature of catheter TCs were assessed by 2 experienced radiologists. Chest x-ray was taken within 1 to 2 days and CDC was withdrawn within 3 to 10 days from those patients with TCs identified by HR-MRI.Results:A total of 38 subjects successfully underwent HR-MRI, including 13 normal and 25 with TCs (fibrin sheath [FS]: n = 21, mural thrombosis [MT]: n = 7, venous thrombosis [VT]: n = 3, intraluminal clots [IC]: n = 4). There was no significant difference between HR-MRCP and chest x-ray in catheter TP determination (P = .124). Normal catheter appeared as “double eyes” on HR-T2WI and “double tracks” on HR-MRCP. TCs appeared as follows: FS displayed as a “thin ring” (<1mm) around the catheter, MT as patchy hyperintensity and VT as a “thick ring” (>5mm) on HR-T2WI. Unilateral IC appeared as a “single eye” on HR-T2WI and a “single track” on HR-MRCP (n = 3). Bilateral IC appeared as neither “eye” nor “track” (n = 1). Catheter withdrawal confirmed FS (n = 16), MT (n = 6), VT (n = 1), and IC (n = 4).Conclusion:HR-MRCP and HR-T2WI are promising methods for visualizing TP and TCs in CDC patients, and are helpful in adjusting the treatment plan and avoiding the risk of pulmonary embolism.

“…Recently, the number of patients undergoing hemodialysis treatment with central venous catheters [1]- [3] has grown. For instance, in the US, it amounts to about 6-150 million each year [4]- [6].…”

“…For instance, in the US, it amounts to about 6-150 million each year [4]- [6]. Insertion of the catheter is an invasive procedure associated with infectious and thrombotic complications [1], [3], [7]- [13], predisposing to the occurrence of a number of complications. It is estimated that every year 12-25% of patients die due to complications and infections [14], [15].…”

“…It leads to increased costs, interruption of therapy as well as it adversely affects the patient's condition [4], [8]. Current prevention methods which include modifications of the inner surface by antithrombotics and antibacterial agents [2], [7], [15]- [18] are so far not sufficiently effective [1]. Only recently [19] the use of the electrochemical impedance spectroscopy has led to the development of a biosensor which can monitor the formation of a biofilm layer at the port of a venous catheter, located just under the skin.…”

“…According to numerous scientific reports [20], [21] and the present study the most threatened part is the tip of the catheter, which is placed in the right atrium of the heart and thus is in constant contact with blood. The fibrin sheath formed mainly by proteins on the surface of the catheter within 24 hours of its insertion into the patient's circulation promotes the subsequent adhesion of pathogens [1]. However, numerous scientists [19], [22]- [25] used bacterial cultures (neglecting the influence of the proteins) for providing a characterization of biofilm growth, e.g.…”

Abstract. The aim of the study was to specify by an impedimetric method the changes observed on the inner wall of central venous catheters for hemodialysis leading to the formation of a biological film. To evaluate these changes a patient-dialyzer model was built in which experimental parameters were kept closely similar to the clinical conditions of hemodialysis. The impedance spectra and SEM/EDS analysis of the biological layer deposited on the inner surface of the distal part of the catheter gave an insight into the structure of film formation and its chemical composition. Since an early detection of biofilm formation inside the distal part of the catheter is crucial for the safety of medical treatment and it usually prompts the implementation of antibiotic therapy. Developed impedimetric method can minimize the risk of infection and ensure the continuity of treatment.
