Safety and feasibility of a diagnostic algorithm combining clinical probability, D-dimer and ultrasonography in suspected upper extremity deep vein thrombosis : a prospective management study

BACKGROUND Although well-established for suspected lower limb deep venous thrombosis, an algorithm combining a clinical decision score, d-dimer testing, and ultrasonography has not been evaluated for suspected upper extremity deep venous thrombosis (UEDVT). OBJECTIVE To assess the safety and feasibility of a new diagnostic algorithm in patients with clinically suspected UEDVT. DESIGN Diagnostic management study....
