"Take Home Points on SVT
- Superficial venous thrombosis refers to a clot and inflammation in the larger, or “axial” veins of the lower extremities and superficial thrombophlebitis refers to clot and inflammation in the tributary veins of the lower extremities. While we previously thought of this as a benign entity, we actually found the superficial venous thrombosis has been associated with concomitant DVT and PE.
- Small, superficial clots can be treated with compression, NSAIDs, and elevation. These patients should be seen for follow up within 7-10 days to make sure the clot has not progressed.
- Clots that are longer than 5 cm should be treated with prophylactic dosing of anticoagulation: fondaparinux 2.5mg subq once daily for 45 days or enoxaparin 40 mg subq once daily for 45 days.
- Clots that are within 3 cm of the sapheno-femoral junction should be treated the same as a DVT.
- A superficial thrombus could mean there is a deeper clot elsewhere, even in the other leg! Take a good history, perform a thorough physical exam and consider a bilateral lower extremity DVT study in concerning patients."
