Thrombus age is ideally measured by history or MRV prior to thrombus removal

Abstract

Many factors are known to be important in order to achieve optimal results after thrombus removal for iliofemoral DVT. Not much is published in the literature about timing the treatment, though many guidelines recommend treatment within 14 days. This time span lies within the phrase of acute DVT according to the definition given in many reporting standards. This article will highlight the value of information acquired from patients directly regarding onset of symptoms versus information acquired from imaging with the purpose of a more precise selection of patients for catheter-directed thrombolysis for iliofemoral DVT. What is the value of clinical information acquired from patients and does the information from imaging have additional value?
