When a procedure is needed
Most DVT and PE are treated successfully with blood thinners alone. Medical Therapy → A clot-removal procedure is considered for an extensive iliofemoral (thigh/pelvis) DVT — where clearing the clot can reduce long-term swelling and post-thrombotic syndrome — and for an intermediate- or high-risk pulmonary embolism that is straining the heart.
What we do — and where
These three procedures are often discussed together, but they do not happen in the same place. Where each is performed depends on what it requires, and on you.
-
Catheter-directed thrombolysis
Clot-dissolving medicine delivered directly into the clot through a catheter, concentrating the effect where it's needed. The medicine infuses over hours, so you are admitted and monitored overnight while it works. -
Pharmacomechanical / aspiration thrombectomy
Physically breaking up and removing the clot, sometimes combined with thrombolysis. Where we do it depends on the size and age of the clot, your other medical conditions, and how closely you need to be watched afterward. -
Imaging-guided treatment of the underlying cause
When a narrowing or May-Thurner compression is found, we reopen it, often with intravascular ultrasound (IVUS) guidance and a venous stent, so the clot is less likely to return. Done acutely alongside the clot, this follows that procedure's site of service; done electively afterward, it is an office-lab procedure.
All three are catheter-based, done through a small puncture rather than open surgery. What separates them is monitoring: a lytic infusion has to run and be watched, so it means an overnight stay. Clot removal alone often does not.
After your procedure
Blood thinners continue to keep the vein clear while it heals, and we arrange follow-up imaging and a plan to prevent post-thrombotic syndrome. Medical Therapy → About DVT & PE →
Why OCC
-
An experienced endovascular team that treats both the clot and its underlying cause in one coordinated plan.
-
IVUS-guided treatment of iliac vein compression and post-thrombotic narrowing when present.
-
IVC filter placement and retrieval when blood thinners can't be used.
