The mechanism of endovenous thrombus formation induced by laser irradiation is different from thromboplastic phlebitis, thus endovenous thrombus formation doesn't affect whole body cruor function.
Alternatively, initially perform a TEE, and if no thrombus is present, cardiovert and therapeutically anticoagulate for a minimum of 4-6 weeks after sinus rhythm is restored.
Long-term treatment to prevent future thrombi from forming can include anticoagulant medications like warfarin or heparin, which inhibit the clotting cascade and prevent clot formation.
Finally, with protein C or S deficiency, there can be warfarin induced skin necrosis, which means tiny thrombi can form in the blood vessels of the skin, causing skin necrosis.
