Risk factors for mortality in patients with upper extremity and internal jugular deep venous thrombosis.
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.
