Background: We sought to evaluate the use of intravascular ultrasound (IVUS) and mechanical thrombectomy (MT) for the treatment of deep vein thrombosis (DVT) in a community hospital setting.
Methods: Data were analyzed among patients with lower extremity DVT who underwent MT from December 1, 2021 to December 1, 2022.
Results: A total of 1263 patients were evaluated and only 8.8% of patients with DVT received intervention. Of them, 42% were women. The mean age and length of stay were 61.3 years and 3.5 days, respectively. For cases that proceeded to intervention, IVUS was used in 89% of cases, 80% received venoplasty, and 30% received stents. The mean number of MT passes was 4 and the mean contrast volume used was 71 mL. Flow was restored in 96.7% of cases. The procedure was unable to be completed in 1.8% of the cases, and 1.8% had a reported complication after the procedure. Vascular surgery was consulted in 64.4% of the cases, cardiology in 33%, interventional radiology in 12.5%, and 10.9% of the patients had multiple consults. MT was associated with postprocedure reduction of hemoglobin levels (13.4 vs 12.1; P < .001) and no change in postprocedure creatinine levels (1.08 vs 1.04; P = .28). IVUS was associated with fewer passes, although this was not statistically significant (P = .09). Additionally, IVUS was associated with increased stenting (P = .03) and venoplasty (P < .001).
Conclusions: MT is shown to be successful in restoring venous flow and is utilized by multiple specialties in the treatment of DVT. Additionally, IVUS was widely used in conjunction with MT, and it was associated with increased advanced interventions, such as venoplasty and stent placement.
