Is Global Limb Anatomic Staging System Classification a Useful Tool in Predicting Lower Limb Revascularization...

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Radiology

Background:

• The Global Limb Anatomic Staging System (GLASS) classification was introduced in 2019 to assess lower extremity arterial injury severity and predict revascularization success.
• Chronic limb-threatening ischemia (CLTI) presents a significant challenge in vascular surgery, necessitating reliable tools for treatment planning.

Purpose of the Study:

• To evaluate the utility and reliability of the GLASS classification in predicting revascularization success for CLTI patients.
• To correlate GLASS stages with clinical characteristics and endovascular treatment approaches.

Main Methods:

• A retrospective analysis of patients undergoing revascularization for CLTI.
• Application of GLASS staging (1, 2, or 3) to angiographic data based on femoropopliteal and infrapopliteal lesion complexity.
• Assessment of technical success, specificity, and accuracy of the GLASS classification.

Main Results:

• GLASS classification demonstrated a sensitivity of 63% (first testing) and 82% (second testing), with a specificity of 77%.
• Patients classified as GLASS 1 and 2 exhibited significantly higher revascularization success rates compared to GLASS 3.
• One-year follow-up showed an amputation-free survival rate of 81.3%.

Conclusions:

• The GLASS classification is a valuable tool for predicting revascularization outcomes in CLTI.
• It offers a standardized method for assessing anatomical complexity in lower extremity arterial disease.
• Further research incorporating additional data is recommended to enhance the predictive power of the GLASS system.
