Abstract
Patients with iliofemoral deep venous thrombosis (DVT) are at highest risk for the postthrombotic morbidity including all aspects of the postthrombotic syndrome. Invasive therapies such as catheter-directed thrombolysis (CDT) and/or mechanical thrombectomy with or without angioplasty and stenting and in some cases open operative thrombectomy improves venous patency, venous valve function, and quality of life in patients with acute iliofemoral DVT. What is the current frequency of acute iliofemoral DVT and how aggressively is it being treated? We hypothesize that the 10-year period frequency of iliofemoral DVT among acute DVT cases is greater than previously reported. Further, we hypothesize that thrombus removal to treat acute iliofemoral DVT is little utilized in current practice. Indiana University (IU) vascular laboratory records from January 1, 1998 to December 31, 2008 were searched by CPT code for venous Doppler ultrasound study (n=7240). A random sample based on the IU medical record number of lower extremity Doppler studies was then selected (n=1020) for retrospective chart review. Corresponding clinical information was gathered from the patients' electronic medical record. Acute DVT occurred in 6.8%, and chronic DVT in...Continue Reading
