Pharmacological management of obstructive peripheral arterial disease: two case reports.

Peripheral artery disease (PAD), also abbreviated as LEAD or lower extremity artery disease, is an important predictor of cardiovascular morbidity and mortality. Rivaroxaban, a selective direct factor Xa inhibitor, is proposed as an additional pharmacologic option for managing this disease. Two patients presented with PAD and high-risk comorbidities. The first case showed how the evaluation of the cardiovascular risk guided the therapeutic management of the patient. The second case was about a patient diagnosed with LEAD who experienced worsening from exertional ischemia toward critical ischemia requiring amputation despite distal revascularization, and parenteral vasodilator therapy to relieve pain. This case suggested a comprehensive care management approach, adapted to PAD progression stages. The PAD management consists nowadays of optimizing the management of cardiovascular risk factors and disease progression. Diagnosis, treatment, monitoring, and patient education should be handled by a vascular specialist in a specialized care unit.
