Summary
Ankle-brachial index (ABI) use is low in peripheral arterial disease (PAD) treatment. Patients not assessed with ABI before intervention showed decreased functional status, highlighting its importance for claudication management.
Area of Science:
- Vascular Medicine
- Noninvasive Diagnostic Techniques
- Peripheral Arterial Disease
Background:
- Ankle-brachial index (ABI) is the recommended first-line test for diagnosing peripheral arterial disease (PAD) in patients with claudication.
- ABI aids in monitoring disease progression and evaluating treatment effectiveness after peripheral vascular intervention (PVI).
Purpose of the Study:
- To evaluate the utilization of ABI in patients undergoing PVI for claudication within the Upper Midwest Region of the Vascular Quality Initiative.
- To assess the functional outcomes of patients who received PVI, with a focus on the impact of ABI measurement.
Main Methods:
- A retrospective review of the Vascular Quality Initiative database (2010-2020) was performed.
- Included patients had undergone PVI for claudication due to native artery atherosclerotic occlusive disease; exclusions applied for infection, tissue loss, rest pain, graft stenosis, or aneurysms.
- Primary outcomes analyzed were ABI, ambulation status, and functional status before and after PVI.
Main Results:
- Out of 3830 procedures, ABI was measured before and after PVI in only 22.5% of patients.
- No significant change in ambulation or functional status was observed overall, regardless of ABI use.
- Patients without ABI measurement before PVI showed a significant decrease in functional status post-intervention.
Conclusions:
- Despite evidence, ABI is underutilized before PVI for claudication.
- Lack of ABI assessment correlates with significant functional decline after PVI.
- Accurate pre-PVI ABI measurement is crucial for identifying patients who will benefit from intervention for claudication.

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.
