Bleeding risk outweighs DVT prevention benefit with subcutaneous heparin in aortic graft surgery; challenges routine prophylaxis in this setting.
Does subcutaneous calcium heparin prevent deep-vein thrombosis in patients undergoing elective aortic bifurcation graft surgery?
In patients undergoing elective aortic bifurcation graft surgery, the risk of bleeding from low-dose subcutaneous heparin outweighs its benefit in preventing deep vein thrombosis.
