Inclusion criteria
Inclusion criteria: 1. Patients aged 40–80 years; 2. BMI >=18.5 kg/m^2 (to avoid malnutrition affecting healing); 3. Cardiology: no decompensated heart failure (NYHA class = 60 mL/min/1.73 m^2; 7.

The ankle-brachial index (ABI) must be >=0.9 (excluding hemodynamic abnormalities); 15. If currently smoking, commit to complete cessation of smoking 4–6 weeks prior to surgery (verified by breath CO measurement); 16. There should be no chronic alcohol dependence (<=40 g/day for males, <=20 g/day for females); 17. For patients with comorbid diabetes, HbA1c levels must be <=7.5% and random blood glucose levels <=11.1 mmol/L within 8 weeks before surgery.
