Objective To analyze the risk factors for venous thrombosis in cancer patients after peripherally inserted central catheter (PICC) placement and to propose corresponding preventive nursing strategies. Methods One hundred cancer patients who underwent PICC placement in our hospital from March 2023 to March 2025 were included in the study. They were divided into a thrombosis-prone group and a non-thrombosis group based on whether venous thrombosis occurred. Clinical data of the two groups were compared, and the factors leading to venous thrombosis were analyzed. Patients in the thrombosis-prone group received acupressure massage and limb elevation, and the nursing outcomes were analyzed. Results Risk factors for venous thrombosis after PICC placement in cancer patients included age, placement time, and use of platelet-promoting drugs. Preventive nursing interventions significantly reduced the incidence of thrombosis. Conclusion Many factors contribute to venous thrombosis in cancer patients after PICC placement. Clinical nursing care requires strengthened risk assessment and timely guidance for patients to engage in exercise to minimize the incidence of venous thrombosis.
