A Finite Element Framework to Study Trauma Risk During Daily Physical Activities on Patients With an Implanted Port-a-Cath

Abstract

Abstract. A Port-a-cath is an implantable device placed under the skin to draw blood or deliver treatments such as intravenous fluids, medications, or transfusions. Patients often worry about accidentally hitting the device or nearby tissues, as it slightly protrudes from the skin. This concern can limit participation in daily activities, including sports, affecting quality of life. In this study, we propose a framework to investigate the risk of accidental tissue trauma by simulating a ball impact in the area surrounding an implanted Port-a-cath using finite element analysis. The simulation revealed increased stress in tissues surrounding the device (approximately five times higher in both the skin and the muscle when the device is implanted), suggesting a potential risk for muscle injury upon impact. These findings highlight the need for awareness regarding external forces acting on the Port-a-cath region during physical activity. To our knowledge, this is the first study using biomechanical modeling to explore trauma risk associated with Port-a-cath impacts. This study represents the first attempt to elucidate this risk in the literature. Overall, this study contributes to improving patient safety and quality of life by providing a quantitative understanding of the mechanical risks associated with implanted Port-a-caths.
