Background: This study tested the hypothesis that rosuvastatin reduces thrombus burden through inhibiting inflammation and suppressing reactive oxygen species (ROS) generation in an inferior vena cava stenosis (IVCST)-induced deep vein thrombosis (DVT) rat model.

Methods. 12-week-old male Sprague-Dawley rats (n = 24) were equally divided into sham control (group 1: laparotomy only), IVCST (group 2: IVC stenosis), and IVCST + rosuvastatin (20 mg/kg/day, orally after induction of IVC stenosis) (group 3). IVC diameter was measured by days 0 and 14 and the right hindlimb thickness was measured by day 0, 7, and 14 prior to scarifying the animals.

Results: The results showed significantly increased IVC diameter and hindlimb thickness in group 2 than in groups 1 and 3, and significantly increased in group 3 than in group 1 by day 14 after the procedure (all p < 0.001). Additionally, WBC count and prevalence of helper T cells, cytotoxic T cells, regulatory T cells, and early and late apoptotic mononuclear cells (MNCs) in circulation were significantly higher in group 2 than in group 1, and were significantly suppressed in group 3 after treatment (all p < 0.001). Furthermore, inflammation at cellular (CD68+ cells) and protein (MMP-9, TNF-α) levels, oxidative stress (oxidized protein) and reactive oxygen species (NOX-1, NOX-2) in IVC also showed similar changes as those of immune cells in circulation among the three groups (all p < 0.01).

Conclusion: Rosuvastatin treatment significantly reduced IVC thrombus burden through inhibiting inflammatory response and oxidative stress in a rodent model of DVT.
