Image and intracavitary electrocardiogram-guided arm port placement in colorectal cancer: A retrospective comparative study

Figure 3 Complications risk and prevention in arm port implantation: Technique comparison and risk factor analysis. ^aP < 0.05 compared to the control group, with all differences being statistically significant. This figure demonstrates the clinical advantages of image pre-measurement combined with intracavitary electrocardiogram positioning technique in arm port implantation for colorectal cancer patients. The bar chart shows that the experimental group had significantly lower incidence rates of total and specific complications (thrombosis, displacement, occlusion, and infection). PSI: Pneumonia severity index; BSI: Bloodstream infection; PPI: Proton pump inhibitor; PPH/S: Primary postpartum hemorrhage/secondary.
