Summary
Resting ankle brachial index (ABI) measurements are a sensitive, cost-effective primary screening tool for infrainguinal autogenous vein grafts. Further evaluation with color flow duplex scanning is crucial for grafts showing ABI changes or other complications.
Area of Science:
- Vascular Surgery
- Medical Imaging
- Diagnostic Procedures
Background:
- Infrainguinal autogenous vein grafts are crucial for peripheral artery disease treatment.
- Effective surveillance is needed to detect graft complications early.
- Non-invasive methods are preferred for routine graft monitoring.
Purpose of the Study:
- To evaluate the indications for routine color flow duplex surveillance of infrainguinal autogenous vein grafts.
- To assess the role of ankle brachial index (ABI) measurements in graft surveillance.
- To determine the utility of color flow duplex scanning in identifying and localizing graft problems.
Main Methods:
- Prospective study of 43 infrainguinal autogenous vein grafts.
- Screening included resting ankle brachial index (ABI) measurements.
- Color flow duplex imaging was performed on the entire graft length.
Main Results:
- A serial fall in resting ABI of more than 0.1 indicated grafts at risk.
- Resting ABI measurements proved sensitive and inexpensive for primary screening.
- Approximately 60% of ABI-screened grafts required further evaluation due to ABI changes or other factors.
- Color flow duplex scanning effectively identified and localized graft problems.
Conclusions:
- Resting ABI measurements are a valuable primary screening tool for infrainguinal vein grafts.
- Grafts with ABI changes > 0.1 warrant further investigation.
- Color flow duplex scanning is essential for detailed graft assessment and guiding further management.
