Objective: To elucidate the natural history of upper extremity deep venous thrombosis (UEDVT), we examined factors that may contribute to the high mortality associated with UEDVT. Methods. Five hundred forty-six patients were diagnosed with acute internal jugular/subclavian/axillary deep venous thrombosis from January 1992 to June 2003 by duplex scanning at our institution. There were 329 women (60%). The mean age +/- SD was 68 +/- 17 years (range, 1-101 years). Risk factors for UEDVT were the presence of a central venous; catheter or pacemaker in 327 patients (60%) and a history of malignancy in 119 patients (22%). Risk factors for mortality within 2 months of the diagnosis of UEDVT that were analyzed included age, sex, presence of a central venous catheter or pacemaker, history of malignancy, location of UEDVT, concomitant lower extremity deep venous thrombosis, systemic anticoagulation, placement of a superior vena caval filter, and pulmonary embolism. Results. The overall mortality rate at 2 months was 29.6%. The number of patients diagnosed with pulmonary embolism by positive ventilation/perfusion scan or computed tomographic scan was 26 (5%). The presence of a central venous catheter or pacemaker (P <.001), concomitant lower extremity deep venous; thrombosis (P =.04), not undergoing systemic anticoagulation (P =.002), and the placement of a superior vena caval filter (P =.02) were associated with mortality within 2 months of the diagnosis of UEDVT by univariate analysis. Pulmonary embolism (P =.42), sex (P =.65), and a history of malignancy (P =.96) were not. Conclusions. These data suggest that the high associated mortality of UEDVT may be due to the underlying characteristics of the patients' disease process and may not be a direct consequence of the UEDVT itself.
