Abstract: Objective To evaluate the clinical value of ultrasound guidance combined with intracardiac electrocardiogram in the implantment of totally implantable access port (TIAP) in the elderly patients. Methods The clinical data of 204 elderly patients with tumor who received TIAP at our department from January 2018 to December 2021 was retrospectively analyzed. The patients were divided into ultrasound combined with intracardiac electrocardiogram group (group A, n=133) and blind puncture combined with X-ray-based location group (group B,n=71). The successful rate, postoperative complications and unplanned removal rate of TIAP were compared between the two groups. Results The successful rate in group A was 99.2%, compared with 91.5% in group B. Both the incidence rates of short-term and long-term complications in group A were lower than those in group B (P<0.05). The unplanned removal rate of TIAP in group A was also lower than that in group B (P<0.05). Conclusions Ultrasound and intracardiac electrocardiogram is a safe and effective technique, which is an important option for clinical implantation of TIAP in the elderly.
