A phenomenological and multiscale modeling of arterial growth and remodeling under endofibrosis

02 november 2020 High level endurance sports, like biking, may lead to a vascular pathology called endofibrosis. Its symptoms are an arterial wall thickening and a reduction of the artery lumen calibre. Cyclists are impacted in the iliac arteries due to a pinching and...

01 juli 2020 Purpose: To prospectively compare the diagnostic capabilities of computed tomography angiography (CTA) to those of digital subtraction angiography (DSA) in endurance athletes with suspicion of arterial endofibrosis. Materials and methods: Forty-five...

Peripheral Vascular Imaging Focusing on Nonatherosclerotic Disease

01 juli 2020 A variety of nonatherosclerotic diseases affect the arteries of the pelvis and lower extremities. Chronic repetitive traumatic conditions, such as popliteal entrapment and external iliac artery fibroelastosis, vasculitis and connective tissue diseases,...

Ankle and arm pressure recordings for the diagnosis of exercise-induced arterial endofibrosis

01 april 2020 BACKGROUND: Measurement of ankle and brachial blood pressure after maximal exercise is largely used to diagnose exercise‑induced arterial endofibrosis (EIAE). AIMS AND OBJECTIVES: We aimed to compare the different available methods and combination of...

Protease-activated receptors are potential regulators in the development of arterial endofibrosis in high-performance athletes

01 april 2019 Objective: High-performance athletes can develop symptomatic arterial flow restriction during exercise caused by endofibrosis. The pathogenesis is poorly understood; however, coagulation enzymes, such as tissue factor (TF) and coagulation factor Xa,...

The biology of external iliac artery endofibosis: What can we learn from this disease to help us treat other fibroproliferative arteriopathies?

01 april 2019 Arterial endofibrosis is a vascular disease that typically affects the external iliac artery in young patients who undergo extreme exercise, mainly bicyclists.1 The diagnosis is indirectly suspected when these extreme athletes undergo ankle-brachial...

Gefäßerkrankungen bei Triathlete

15 januari 2019 Die überwiegende Mehrzahl der Triathleten weist keinerlei kardiovaskuläre Risikofaktoren auf. Dennoch gibt es bei diesem für uns Gefäßchirurgen untypischen Patientenklientel zunehmend Berichte über arterielle Komplikationen. In der Literatur werden 3...

Pedal power measurement as a diagnostic tool for functional vascular problems

01 januari 2019 Background: Cyclists with flow limitations in the iliac arteries complain of pain and loss of power. To investigate whether pedal power measurement has added value in diagnosing the underlying cause of flow limitations in the iliac arteries, we...

Near-Infrared Spectroscopy Is Promising to Detect Iliac Artery Flow Limitations in Athletes: A Pilot Study

20 december 2018 Endurance cyclists have a substantial risk to develop flow limitations in the iliac arteries during their career. These flow limitations are due to extreme hemodynamic stress which may result in functional arterial kinking and/or intravascular lesions....

Near-infrared spectroscopy of the thigh fails to discriminate cyclists with arterial endofibrosis from normal asymptomatic athletes

01 oktober 2018 BACKGROUND: This study is to assess the applicability and performance of the near-infrared spectroscopy (NIRS) in the diagnosis of exercise-induced arterial endofibrosis (EIAE). METHODS: NIRS was measured on each thigh, in 12 highly trained...

Focus on echovascular imaging assessment of arterial disease: complement to the ESC guidelines (PARTIM 1) in collaboration with the Working Group on Aorta and Peripheral Vascular Diseases

18 september 2018 The main goal of the present document is to provide a set of practical recommendations for ultrasound imagers who are interested in artery diseases or for physicians who intend to undertake vascular procedures. This is the first part of the work. It is...

MRI to investigate iliac artery wall thickness in triathletes

01 september 2018 Objectives: Endofibrosis was first described in endurance athletes. This rare disease is characterized by intimal hyperplasia of iliac arteries. Due to non-specific symptoms diagnosing could be very challenging and delayed. This represents a serious...

Long-term results of the surgical treatment of external iliac endofibrosis

01 oktober 2017 The surgery of external iliac endofibrosis (EIE) is considered only in top sportspeople, who are always very demanding. For this reason it remains debated. The aim of our study was to evaluate the long-term results, seldom reported, of this surgery.
