What can I do about a DVT after endovenous surgery?

My surgery was one month ago. I now have a large clinging DVT. I went yesterday for another ultrasound and it is larger and moving. I am taking aspirin as instructed. Too early for blood thinners. When can I expect to get rid of it?

Your doctor needs to continue to watch the clot with ultrasound. Pain, swelling, and other symptoms should be monitored as well. Blood thinners like Coumadin or Lovenox might be warranted. It can take weeks to months for a clot to resolve.

My routine post ablation is to check with an ultrasound one week post procedure. If something resembling a filling defect or "clot" is noted on that scan then I will start the patient on Lovenox and Coumadin to prevent the
progression of a small and early DVT to a larger and more difficult to resolve DVT. If the clot extends to the common femoral vein it should be treated as a DVT.

If it is a true DVT, you need full anti-coagulation, not just aspirin.

I can't provide an answer for you, as there is not enough information. Where is the clot? If it is at the saphenofemoral or popliteal junction it is a heat induced thrombus and no treatment is needed. If it is truly in your deep veins and worsening, then you should be anticoagulated.

This question depends on the size of clot and if those deep veins are completely occlusive or not. Frequent follow up appointments are necessary and your primary care provider will be able to better address that question in your case. Everyone is different and healing times can vary drastically from patient to patient.

The DVT seems to be getting larger and actually extending based on your description. This is concerning and depending on where it is and how large the clot actually is, I would be compelled to treat you with anticoagulation medications, provided that you do not have any other contraindications to taking such medications since blood thinners are not benign. The DVT probably will not go away until you go on the blood thinners. And since you have already been on aspirin, which does not seem to be working, some form of anticoagulation is called for. The goal of the blood thinner, however, is not to necessarily get rid of the clot, but in fact to prevent it from getting bigger and possibly breaking off and going to your lungs resulting in a pulmonary embolus. When large enough, these pulmonary emboli can actually be fatal or do irreversible harm to your lungs.

Your question is difficult to answer based on the info given. Sometimes a clot can form just above the saphenofemoral junction within one week of the closure procedure but this usually resolves within 2 weeks. There are criteria for treating this with anticoagulation. DVT forming in any other deep vein is usually treated with anticoagulation. From what you describe I would recommend that you ensure that ASA is sufficient treatment and not full anticoagulation.
