“Iliofemoral DVT question?”

I am a 30 years old female and I was diagnosed with an iliofemoral DVT after my c-section 2 months ago. I was referred to interventional radiology by my doctor because they recommended I get a thrombectomy due to how close the clot is to my inferior vena cava. The radiologist did not recommend a thrombectomy and instead thought we can move forward with medication management of the clot, as he has stated that the clot has shrunk a little bit. I now don't know who to believe and want to get a second opinion because I think a thrombectomy is important, as I grow anxious about the post-thrombotic syndrome. The pain is gone from the clot but I still get mild swelling and leg color changes. What should I do?
