Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of the proposed study is to define independent parameters for the diagnostic assessment of the perfusion situation of the gluteal muscle based on multispectral optoacoustic tomography (MSOT) in patients with gluteal claudication in Fontaine stage II (intermittent claudication) pre and post-intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a monocentric, prospective study which aims to exanimate the optoacoustic signals in gluteal muscle after a exercise in patients with PAD in Fontaine stage II before and after the revascularisation to verify the change of MSOT by improved vascularization. MSOT data will be correlated with CCDS, ABI, treadmill test, subjectively perceived absolute walking distance in everyday life, PAD-related life quality (VASCUQOL-6) and TASC II classification in angiographic imaging (only in case angiographic imaging is available and independent from this study).

Patients with gluteal claudication in Fontaine stage II will be recruited during the consulting hours of the Department of Vascular Surgery, University Hospital Erlangen. Following detailed information about the study and after providing written consent, relevant clinical data will be collected from the electronical patient file, if available. In addition, a thorough anamnesis interview for relevant data and CCDS would be performed. Afterwards, the MSOT parameters will be recorded on gluteal muscles before and after a stepper exercise two minutes or until the occurrence of claudication pain in the gluteal muscle. The more affected side is examined. All data will be adequately pseudonymized in compliance with data protection regulations before they are used for statistical analysis. The duration of the study for participants will be max. 90 minutes. The angiographic imaging will be reviewed and analyzed.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

• Patient with gluteal claudication in Fontaine stage II and corresponding stenosis (common iliac artery, internal iliac artery or distal aorta)

Exclusion Criteria

* Patients with PAD in Fontaine stage I, III and IV or Rutherford category 0, 4, 5 and 6 or healthy volunteers with diabetes mellitus, chronic renal failure, claudication symptoms, abnormal ABI or non-palpable foot pulses
* People with age under 18
* Absence of written consent
* Safety concerns of the study physician (person with physical, mental or psychiatric conditions which, by the judgement of the study physician, would compromise the person's safety or the quality of the data, thereby rendering the person an ineligible candidate for the study
