Upper extremity deep vein thrombosis in hospitalized central venous catheter carriers and non-carriers: A retrospective cohort study.

Objectives: Prognostic differences between central venous catheters (CVC) carriers and non-carriers, who have upper extremity deep vein thrombosis (UEDVT), have been described; however, evidence in hospitalized patients is limited.

Materials And Methods: This retrospective cohort study included hospitalized patients from March 2012 to March 2023 with UEDVT, classified into CVC-associated and non-CVC-associated UEDVT groups. Rates of thrombotic recurrence, hemorrhage, post-thrombotic syndrome, and death from pulmonary embolism were analyzed using Kaplan-Meier curves and Cox proportional hazards models.
