Results of external iliac artery reconstruction in avid cyclists
Objective: We report the midterm results of external iliac artery reconstruction in 25 high-performance cyclists. Methods: Cyclists undergoing arterial reconstruction for symptomatic external iliac arteriopathy at a single institution between October...
-
Introduction: Endurance athletes may suffer from intermittent claudication. A subgroup of 16% has severe iliac artery stenosis due to endofibrosis. In this study we report the short- and mid-term results of endarterectomy with venous patching....
-
Endofibrosis in athletes: is a simple bedside exercise helpful or sufficient for the diagnosis?
Objective: Ankle-to-brachial index (ABI) can be easily performed by all physicians. The Ruffier-Dickson (RD) test is an easy procedure to attain moderate exercise at the bedside for physicians who do not have an ergometer. Design: Retrospective...

Iliac artery compression in cyclists: mechanisms, diagnosis and treatment
Objectives: To review the mechanisms, diagnosis and treatment options for symptomatic iliac artery compression in cyclists. Methods: Pubmed, Medline, Embase and Google were searched using combinations of the terms 'iliac artery disease', 'iliac artery...
-
Introduction: High performance athletes, predominantly professional cyclists, can develop symptomatic arterial flow restriction in one or both legs during exercise. The ischemic symptoms are caused by endofibrosis and/or kinking of the external iliac...
-
The development of sports activities in the over forties has increased the number of middle-aged patients performing heavy-load exercise. The normal response of ankle systolic blood pressure (ASBP) and ankle to brachial index (ABI) to intense exercise...
-
Simultaneous arterial pressure recordings improve the detection of endofibrosis
Purpose: Exercise improves the diagnostic performance of ankle-to-brachial index (ABI) in the detection of exercise-induced arterial endofibrosis (EIAE). Pressure values for all four limbs are required to calculate ABI, but rapid systemic pressure...
-
Objective: Review of a 10 year-experience, to evaluate the efficacy of pre-operative investigations in the detection of external iliac artery (EIA) endofibrosis in top endurance athletes. Design: Retrospective study. Materials: From September 1995 to...
-
Flow limitations in the iliac arteries of endurance athletes during exercise were previously ascribed solely to intravascular lesions. We postulate that functional kinking of the arteries can also result in flow limitations. However, the diagnostic...
-
Leg complaints at maximal exercise in endurance athletes may have many causes, including arterial flow limitations in the iliac arteries. Such flow limitations can evolve into serious health problems due to increasing intravascular obstruction or even...
-
Purpose: Kinking of the iliac arteries can cause flow limitations in endurance athletes. Such kinking may be treated by surgical release of the iliac arteries. However, when the length of the iliac artery is excessive, this may not be effective....
-
Background: Endurance athletes often have restrictions in flow in their iliac arteries during exercise. Such restrictions have previously been ascribed solely to intravascular lesions. We postulate that flow could also be restricted by functional...

Diagnosing external iliac endofibrosis by postexercise ankle to arm index in cyclists
Purpose: The aim of this study was to determine a noninvasive method of evaluating external iliac endofibrosis in cyclists. Methods: Eighteen highly trained male cyclists were divided into two groups: a pathology group (PG; 3 professional and 4 elite)...
-
Purpose: This study compared ankle to brachial pressure indices (ABPI) before and after maximal exercise in three groups in order to investigate maximal exercise testing and ABPI as a useful procedure for the differential diagnosis of exercise-induced...

Vascular complications in high-performance athletes
Purpose: The purpose of this study was to evaluate our experience with the diagnosis and management of vascular injuries in a group of high-performance athletes. Methods: Between June 1994 and June 2000, we treated 26 patients who sustained vascular...
-
Purpose: This study defined how ankle arterial blood pressure measurements should be analyzed for the detection of moderate arterial disease (asymptomatic while walking). We used external iliac artery endofibrosis as a unique model of an isolated...

External Iliac Artery Endofibrosis in a Young Cyclist
An 18-year-old cyclist was referred to the laboratory for unexplained pain in his left lower limb during exercise. He had started competition at 14 years of age and had cycled ≈10 000 km/y in the preceding 5 years. He had complained for 18 months of a...

Echography of external iliac artery endofibrosis in cyclists
Forty-eight cyclists were studied for suspected external iliac artery endofibrosis with ultrasound B-mode imaging. In highly trained competition cyclists, symptoms of external iliac artery endofibrosis were characterized by lower limb claudication...
