Follow-Up
The follow-up program included assessments at six-month, 1-year and 2-year intervals. It included the clinical evaluation, Doppler ultrasound examination, and the ABI measurement.
The limb salvage rate was 100% in the asymptomatic group and above 90% in the symptomatic group. The primary patency was documented.
The primary patency rate in the posterior approach group was 93%, 70%, and 63% in comparison to 75%, 65%, and 50% in the medial approach.
The Run-off classification of the patients were divided into <2 and ≥ 2 below knee vessels.
The patients with a pre-operative Run-off <2 showed a primary patency rate 61%, 44% and 33% while the results at the run-off ≥ 2 group were 91%, 74% and 63%.
