ABSTRACT
OBJECTIVE:
The main objectives of the present study were to analyze the right internal jugular vein tunneled dialysis catheter (TDC) tip displacements, functional changes, pathway deformities, and angulations associated with different arm positions.METHODS:
We prospectively studied 21 patients who had undergone TDC implantation for hemodialysis via the right internal jugular vein at a single center from February to September 2020. After implantation, a baseline resting fluoroscopy image was taken, and three movement-mimicking images of the ipsilateral arm were obtained for comparison, with the arm in maximum abduction, maximum flexion, and maximum adduction. Device function was analyzed for each movement-mimicking position and correlated with catheter tip displacement, catheter deformity, and catheter pathway angulation.RESULTS:
TDC pathway deformity occurred in 16 patients (69.5%). Deformities were more frequent in the movement-mimicking positions than in to the control resting baseline images (P = .004). The different arm positions did not lead to significant tip displacement (either horizontal or vertical; P > .05), nor did they result in significant pathway angulation between the subcutaneous and intravenous regions (P = .114). However, in the maximum abduction position, a positive relationship was present between the catheter pathway angle and impairment of catheter function (P = .028).CONCLUSIONS:
Catheter deformity was more frequent and more severe with maximum adduction and flexion of the arm. Although no significant changes were observed in the tip of the catheter with the movements, a positive relationship was found between the catheter pathway angle and impairment of catheter function with the arm in the maximum abduction position.Palabras clave
