What is the antibiotic of choice for a patient with peripheral vascular disease and ischemia of the left foot?

There are no official guidelines to assist in answering this question. I will search for relevant research papers instead.

From the Research

Antibiotic Treatment for Peripheral Vascular Disease

There is no direct evidence to support the use of a specific antibiotic as the treatment of choice for a patient with peripheral vascular disease and ischemia of the left foot.

• The provided studies focus on the management of peripheral vascular disease, acute limb ischemia, and pharmacological interventions for peripheral artery disease, but do not specifically address the use of antibiotics in this context 1, 2, 3.
• One study investigated the use of long-term antibiotic treatment (roxithromycin) to prevent progression of peripheral arterial occlusive disease, but found no significant benefit 4.
• Other studies discuss pharmacological interventions for peripheral artery disease, including antiplatelet therapy, exercise training, and various pharmacological agents, but do not mention antibiotics as a treatment option 2, 3, 5.

Relevant Pharmacological Interventions

The following pharmacological interventions are mentioned in the context of peripheral vascular disease and peripheral artery disease:

• Antiplatelet therapy (aspirin) 3
• Cilostazol and pentoxifylline for symptomatic treatment of intermittent claudication 2, 5
• Calcium channel blockers for Raynaud's phenomenon 5
• Prostaglandins and growth factors for critical limb ischemia 5
