Eligibility

Sex/Gender

All

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: Patients who have undergone endovascular peripheral intervention (EPI) using digital (subtraction) angiography or digital variance angiography (DVA) of the lower extremity (femoral, popliteal, cruro-pedal and iliac arteries) at the University Heart Center Freiburg-Bad Krozingen (Bad Krozingen site).

Exclusion criteria

Exclusion criteria: Patients for whom DVA could not be performed due to motion artifacts in the image acquisition, no or partly utilized low dose protocols, or occasional CO2 acquisitions.
