Q: Prophylaxis to prevent deep venous thrombosis and pulmonary embolism - VTE - should be continued for at least how long after spinal cord injuries (SCI)?
A) Two weeks
B) Four weeks
C) Three months
D) Six months
In patients with acute SCI, after considering all risks and benefits, usual recommended duration for VTE prophylaxis is about three months. Ideally, pharmacologic intervention with low molecular weight heparin (LMWH) is recommended but warfarin with Internationalized Normalized Ratio (INR) of 2 to 3 is also acceptable.
