Details and patient eligibility

About

A data request will be made regarding the tests conducted by the subject related to their performance, as well as the results of the medical diagnostic tests performed. The requested data/variables pertain to physical performance: power output on the pedals during training sessions, tests, and competitions, as well as medical tests during the diagnostic process.

Full description

The medical tests include those performed during the diagnostic process of the pathophysiology of external iliac artery endofibrosis: imaging tests (Doppler ultrasound), exercise stress tests, computed tomography (CT) imaging, and intravascular ultrasound (IVUS). Data collection will be carried out prior to analysis and processing of the results; all data will be anonymized.

Enrollment: 1 estimated patient

Sex: Male

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Clinical diagnosis of external iliac artery endofibrosis confirmed by medical imaging (e.g., Doppler ultrasound, CT scan, or IVUS).

Age between 18 and 65 years.

Must be a regular cyclist (at least 500 training sessions per year for the past 5 years).

Ability to complete physical performance tests (e.g., cycling power output measurements, Lactate Threshold test).

No prior surgical intervention for external iliac artery endofibrosis or other lower extremity diseases

Willingness to provide informed consent and participate in the study.

Exclusion criteria

History of major cardiovascular disease (e.g., heart attack, stroke).

Pregnancy or breastfeeding.

Use of medications that significantly affect vascular health (e.g., anticoagulants, steroids).

Uncontrolled diabetes or other chronic metabolic disorders.

Recent lower extremity surgery (within the last 6 months).

Any condition that could interfere with the performance tests (e.g., neurological disorders, severe joint pain).

Diagnosis of other vascular diseases (e.g., deep vein thrombosis, atherosclerosis) that could affect arterial function.

History of systemic or local infections that may impact the vascular system.

History of significant trauma or injury to the lower extremities (e.g., fractures, ligament tears).

Any condition preventing safe participation in physical tests, including severe cardiovascular or musculoskeletal limitations.
