Perfusion Angiography and Critical Limb Ischemia.

This evaluation investigates the prognostic value of perfusion angiography software to be used during CLI interventions. Quantitative analysis of the software data will determine how well the software predicts the clinical outcome of CLI patients. Also, patient demographics and non-invasive measurements (standard of care treatment) will be collected in this study.

Perfusion Angiography, in relation with known parameters, describes the ultimate prognostic model in revascularized Critical Limb Ischemia patients.

The total duration of the study is expected to take approximately 2 years.

The patient will undergo standard of care medical treatment for his or her CLI condition. During the procedure, the interventionalist will take runoffs of the affected leg and foot, before and after the revascularization procedure. The DSA of the foot, pre- and post, will be automatically processed in the perfusion angiography software solution and displayed on the workstation in the control room. Retrospectively, the data will be post-processed and quantitative analysis will take place. After the procedure is finished, the patient will go home. When the patient returns to the outpatient clinic (standard of care), healing of the wound will be logged.
