3. Guys: I am in our ED and I need you gurus to settle a disagreement. I am outside the room of a 63-year-old man who presented with a swollen right calf. Eight weeks ago he underwent inguinal hernia repair. There were no complications, he was treated with 1ntermittent pneumatic compression during surgery. He was ambulatory post surgery. Nine days ago he sustained soft tissue trauma to the right leg. Seven days ago he noted intermittent pain in the right calf. He was able to provoke the pain by compressing the calf. He came to the ED several hours ago. He has been healthy. So here is the problem. The ED physician says that with the negative D Dimer that this is not DVT and the patient can go home without further evaluation. I think that with the reproduction of posterior knee pain with dorsiflexion of the right foot that he has a positive “Homans Sign” and that the likelihood of DVT is high. I need you guys to weigh in.

13. Pearls from the Guys  Calf pain 8 weeks post hernia repair and had appropriate DVT prophylaxis relating to the surgery  9 days post leg trauma  Physical exam signs of DVT are unreliable  Forget “Homans Sign”  Determine whether DVT “Likely” or “Unlikely”  Wells Score  Primary Care rule  When indicated, use D-Dimer  No need for imaging if DVT is “Unlikely” and the D-Dimer is negative  Consider other causes of calf pain
