Graphical Abstract

Abstract

Background

Despite restored patency, catheter-directed thrombolysis (CDT) has variable efficacy in preventing post-thrombotic syndrome (PTS); biomarkers may clarify PTS pathophysiology and guide patient selection for CDT.

Objectives

To investigate relationships between biomarkers, patency, popliteal reflux, and PTS.

Methods

This prespecified CAVA trial subanalysis included patients with first acute iliofemoral deep vein thrombosis (DVT), randomized to standard treatment (ST) or ultrasound accelerated CDT (UACDT). Baseline blood samples were analyzed for fibrinogen, CRP, IL-6, IL-10, VEGF-A, P-selectin, E-selectin, ICAM-1, VCAM-1, MMP-2, MMP-9, and adiponectin. Patency and reflux (duplex ultrasound), and PTS (Villalta score) were assessed at 1-year and long-term follow-up (LT).

Results

Among 108 patients (51 UACDT, 57 ST), absence of patency at 1-year was associated with higher baseline CRP and fibrinogen in both groups, and elevated IL-6 and VEGF-A in the ST group. Reflux at LT was associated with lower IL-6 and adiponectin in the UACDT group. (Moderate-to-severe) PTS at LT was associated with higher baseline MMP-2 and lower IL-10 in the UACDT group, and lower baseline VCAM-1 and adiponectin in the ST group.

Conclusion

Pro-inflammatory processes are linked to reduced patency, with UACDT improving patency in patients with enhanced inflammatory responses. LT reflux is associated with impaired vasoprotective properties. PTS involves impaired anti-inflammatory responses and tissue remodelling both not modifiable by UACDT. Therefore, biomarker-guided treatment selection may potentially improve treatment outcome.
