Purpose: To compare intravascular ultrasound (IVUS) use in lower extremity deep venous thrombosis (DVT) interventions with respect to unplanned 3-month readmissions and in-hospital outcomes using a national database.

Materials and Methods: The NRD was queried from 2016 to 2022 for adult patients with acute or chronic DVT who underwent endovascular intervention. Patients were stratified based on the usage of intraoperative IVUS (ICD-10 codes: B54BZZ3, B54CZZ3, and B54DZZ3). Inverse probability weighted regression adjustment was used to assess the association of IVUS use with regards to 30-, 90-, and 180-day readmissions as well as 30-, 90-, and 180-day reintervention. Additional subgroup analysis was conducted for patients with Iliofemoral DVT intervention.

Results: A total of 57,948 patients were included; 7,660 (13.2%) received an intervention that utilized IVUS. IVUS usage was associated with lower risk of 30-day unplanned readmission (Relative risk [RR]: 0.988, p=0.031; Number Needed to Treat [NNT]: 85). IVUS use had similar risk for all other outcomes (all p >0.05). Among the patients with iliofemoral DVT intervention, IVUS use was associated with lower risk of 30-day unplanned readmission (RR: 0.988; p=0.028; NNT: 81) and reintervention (RR: 0.99, p=0.046; NNT: 152). IVUS use had similar risk for all other outcomes compared to no IVUS use (all p >0.05).

Conclusion: IVUS use was associated with a reduction in 30-day unplanned readmissions, particularly among those with iliofemoral DVT, where IVUS was also associated with fewer early reinterventions. No statistical differences were observed for other in-hospital or long-term outcomes. These findings suggest that IVUS may provide incremental clinical benefit in complex DVT interventions, especially in the iliofemoral subset, though further prospective evaluation is warranted to clarify its role in optimizing patient outcomes.
