Achtergrond van het onderzoek
Background:
A professional cyclist cycles approximately 25,000 km a year and flexes the hip 8,000,000 a year while leg blood flow is in the range of 10-15 liters a minute. This poses a substantial hemodynamic load on the iliac artery. As a result, a proportion of endurance athletes develop a limitation in leg circulation due to arterial narrowing in this iliac artery. An early ‘Lancet’ study of the department of Sports Medicine of Máxima Medical Centre (MMC) found that 20% of professional cyclists were suffering from such a sport-related Flow Limitation in the Iliac Artery (FLIA) necessitating treatment [1]. The incidence in recreational cyclists is unknown. But with 849,000 recreational cyclists in the Netherlands that cycle over 3,000 km a year with an impressive 1,000,000 hip flexions many of them come to the same mileage as a professional cyclist posing them at risk for FLIA [2]. If untreated, FLIA may have a pronounced impact on quality of life. Professional careers are almost always ended. In a substantial subset of cyclists abnormalities become more pronounced. This may even lead to complete occlusions, with severe symptoms in daily life [3-6].
Problems:
Most patients want to return to sports after treatment. This gives great demand to the surgical solution that has to withstand the extreme loading. Ideally, treatment must have a long-term beneficial effect with limited complications. In order to choose the most optimal treatment, evaluation of treatments is essential. There are only two centres worldwide that have treated substantial numbers of these patients during the last 20 years enabling such evaluation, of which MMC is one. Follow-up studies for the different treatment options are limited. Studies with long term follow-up (> 5 year) are even not available at all. This is a major drawback since these patients are on average below 30 years old with an expected life span > 50 years.
Methods:
In the last 20 years, over 350 patients were diagnosed and operated for FLIA in our hospital in a prospective research setting. We will create a database encompassing all relevant gathered data over these last 20 years. Patients that have undergone the different types of treatment will be identified and individually contacted through phone, letter or e-mail by representatives of the treatment team with a questionnaire and if relevant additional testing.
Aims:
The aims of the current project are:
- To assess short-term effects and complications of the different treatment options in relation to pre-operative findings.
- To assess the development of treatment effects (mid- and long-term), recurrence of disease and complications over time.
- To improve our data handling by creating a data management system, which will enable us to continuously evaluate treatments in the future.
Doel van het onderzoek
Conservative treatment:
1. Most patients accept/improve with regards to their complaints
Onderzoeksopzet
All patients who are operated between 1997 and 2017 will be contacted by phone if they are willing to participate in this research.
If so, all patients receive an informed consent form and a return envelope. Moreover, they receive a questionnaire regarding their physical activities, and if applicable: complaints.
