Background: Catheter directed thrombolysis (CDT) is being increasingly utilized in the treatment of patients with proximal lower extremity (LE) deep vein thrombosis (DVT). Although angioplasty and stenting may be required at the time of CDT, the nationwide trends in the use of these adjunctive interventions remains unknown.
Methods: The Nationwide Inpatient Sample (NIS) database was used to identify all patients with proximal LE or caval DVT who underwent CDT between January 2005 and December 2013 in the United States (US). Amongst this patient cohort, we identified those patients who had adjunctive angioplasty and stent placement. Cochrane-Armitage trends test was used to evaluate the trends.
Results: During the nine-year study period, a total of 141,258 patients with the principal discharge diagnosis of proximal LE DVT were identified and among these 7398 (5.2%) patients were treated with CDT. Overall, 59.5% of all CDT patients underwent adjunctive angioplasty and 27.4% of all patients were stented. There was a small but statistically significant increase in the use of angioplasty and stenting over the course of the study period (Figure 1).
Conclusions: Among the cohort of US patients with proximal LE or caval DVT, the majority of patients underwent adjunctive angioplasty and over a quarter of all patients had venous stenting. There was minimal variation in the rates of angioplasty and stenting over study period.
