Objective:
Catheter-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.
Methods:
From 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.
Results:
There 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
Conclusions:
More than half of CAUEDVT resolve

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
