Key result
Graduated compression stockings combined with low dose heparin significantly reduced postoperative DVT compared to low dose heparin alone (4.08% vs 12.24%; P<0.004).
Why the study?
Does the addition of graduated compression stockings to low dose heparin reduce the frequency of postoperative deep venous thrombosis in patients undergoing major abdominal surgery?

The combination of graduated compression stockings and low dose heparin significantly reduces the frequency of postoperative DVT compared to heparin alone in patients undergoing major abdominal surgery.
S Törngren (1980) conducted an RCT in postoperative deep venous thrombosis (n=98). Graduated compression stocking vs. Control leg (no stocking) was evaluated on Deep venous thrombosis (DVT) (p=< 0.004). Graduated compression stockings combined with low dose heparin significantly reduced postoperative DVT compared to low dose heparin alone (4.08% vs 12.24%; P<0.004).
