[Non-invasive diagnosis of occlusive lesions of the aorto-femoral segment]
Insights
A novel device noninvasively assesses aorto-femoral artery hemodynamics by compressing arteries under the inguinal ligament. This method accurately diagnoses iliac artery stenosis and quantifies collateral circulation in patients.
Area of Science:
- Vascular Surgery
- Medical Devices
- Diagnostic Imaging
Context:
- Noninvasive assessment of aorto-femoral hemodynamics is crucial for diagnosing peripheral artery disease.
- Current methods may be invasive or lack precision in evaluating stenosis and collateral flow.
- A new device offers a noninvasive approach to examine the aorto-femoral segment.
Purpose:
- To introduce and evaluate a novel device for noninvasive hemodynamic examination of the aorto-femoral segment.
- To assess the device's capability in detecting iliac artery stenosis and quantifying collateral circulation.
- To validate the device's performance in a clinical setting with a significant patient cohort.
Summary:
- A device is presented for noninvasive hemodynamic assessment of the aorto-femoral segment, utilizing controlled arterial compression under the inguinal ligament.
- Arterial pressure is measured via an ultrasonic sensor during pneumatic balloon decompression.
- The study examined 369 patients, identifying various stages of iliac segment stenosis (from 50% to pronounced) and diagnosing iliac artery occlusion with collateral circulation quantitation.
Impact:
- Provides a noninvasive tool for early detection and characterization of aorto-femoral and iliac artery disease.
- Enables accurate diagnosis of stenosis severity and assessment of collateral pathways, aiding treatment decisions.
- Offers a potentially more accessible and patient-friendly method for hemodynamic evaluation compared to existing techniques.
Abstract:
A device is proposed for a noninvasive examination of hemodynamics of the aorto-femoral segment which allows to make compression of the arteries under the inguinal ligament. The arterial pressure is measured with an ultrasonic sensor under decompression of the pneumatic balloon. Under examination there were 369 patients. The examination has revealed different stages of stenosis of the iliac segment from the initial symptoms (50% stenosis) up to a pronounced stenosis. The occlusion of iliac arteries was diagnosed and collateral circulation was quantitated.
