ObjectiveCatheter-associated upper extremity deep venous thrombosis (CAUEDVT) is well known; however, resolution rates and factors affecting resolution of CAUEDVT are not well characterized. This study determined resolution rates and factors associated with resolution of CAUEDVT.MethodsFrom January 1, 2002, to June 30, 2006, 1761 upper extremity venous duplex ultrasound (DU) studies were performed, and a new UEDVT was found in 253 (14.4%). Of these, 150 patients had routine follow-up and 101 had CAUEDVT. Demographics, follow-up DU results, and risk factors for venous thrombosis were recorded in the patients with follow-up studies and CAUEDVT. Univariate analysis and multivariate logistic regression analysis was performed to determine independent risk factors for complete thrombus resolution.ResultsThere were 49 men (49%) and 52 women (51%) with CAUEDVT and follow-up studies. Mean age was 49 years (range, 5 months-80 years). Patients with CAUEDVT had risk factors for venous thrombosis that included malignancy in 34%, recent surgery/trauma in 34%, known hypercoagulable state in 11%, concomitant lower extremity DVT in 21%, and pulmonary embolism in 5%. Complete resolution of DVT on follow-up was documented in 46%. Thrombosis resolved in only 25% (6 of 24) when the catheter was not removed (P ConclusionsMore than half of CAUEDVT resolve Copyright 2010 Society for Vascular Surgery. Published by Mosby, Inc.
