[S3 guidelines on the diagnostics, treatment and aftercare of peripheral arterial occlusive disease : Key points and...

Area of Science:

• Vascular Surgery
• Geriatric Medicine
• Interventional Cardiology

Background:

• Previous S3 guidelines addressed interventional and surgical treatments for peripheral arterial occlusive disease (PAOD) separately.
• The classification of critical leg ischemia lacked standardized prognostic indicators for wound and infection.
• Geriatric considerations and frailty were not explicitly integrated into PAOD treatment strategies.

Purpose of the Study:

• To present the updated S3 guidelines for the diagnosis, treatment, and aftercare of peripheral arterial occlusive disease.
• To integrate interventional and surgical treatment modalities based on obstruction location and clinical stage.
• To incorporate geriatric aspects, including frailty assessment, into PAOD management.

Main Methods:

• Joint evaluation of catheter-supported interventional and surgical treatment methods.
• Prognostic classification of critical leg ischemia using local wound and infection conditions.
• Dedicated chapter addressing geriatric aspects and the impact of frailty on treatment goals.

Main Results:

• Treatment strategies for PAOD are now unified, considering arterial obstruction site and clinical stage.
• Critical leg ischemia staging is refined through wound and infection classification, offering prognostic relevance.
• Geriatric frailty is recognized as a crucial factor influencing treatment decisions and goals in PAOD patients.

Conclusions:

• The updated S3 guidelines offer a consolidated approach to PAOD treatment, integrating interventional and surgical options.
• Prognostic stratification for critical leg ischemia is enhanced by incorporating wound and infection severity.
• Personalized PAOD management is emphasized, particularly for geriatric patients, by considering frailty and adjusting treatment objectives.
