Determination of optimal catheter insertion depth in totally implantable venous access ports via three-dimensional reconstruction of cervicothoracic veins: a cross-sectional retrospective analysis

Abstract Background Precise positioning of the catheter tip at the cavoatrial junction (CAJ) is critical for totally implantable venous access port (TIVAP) safety; however, it remains technically challenging. Here, we propose a novel preoperative method using non-contrast chest computed tomography (...
