Final answer:
For recurrent embolus despite anticoagulation, treatments include thrombolytic therapy, dual antiplatelet therapy (DAPT), and potentially surgical interventions such as angioplasty, stents, or bypass surgery to restore blood flow.
Step-by-step explanation:
The recommended treatment for a patient experiencing a recurrent embolus despite anticoagulation therapy may vary, but it can include more aggressive options such as thrombolytic therapy, which involves the administration of drugs like streptokinase to dissolve the clot. When there is a risk of a recurrent stroke, physicians may prescribe aspirin combined with another antiplatelet drug, known as dual antiplatelet therapy (DAPT), to prevent clot formation. Additionally, for severe cases where embolism keeps recurring and conservative treatments fail, surgical procedures such as balloon angioplasty, stents, or bypass surgery might be necessary to restore normal blood flow and prevent further embolic events. In some circumstances, a mechanical device such as a coronary assist device may be employed when the damage is extensive, to supplement the heart's pumping action.
