Sensitivity to entrance conditions of wall shear stress in a curved vessel
This study aims to numerically investigate the impact of entrance velocity distributions on wall shear stress in a simplified curved vessel model. The flow in a single‑curved vessel is simulated with Reynolds numbers adjusted to a Newtonian...
-
Purpose: The aim of the study was to determine the flexion point's location of the ilio-femoral arterial axis and its angulation. Materials and methods: Thirty-seven dynamic digital subtraction angiographies were analyzed and were included in the...

Hintergrund: Die iliakale Endofibrose (IE) ist eine seltene arterielle Erkrankung bei Ausdauerathleten, insbesondere Radrennfahrern und Triathleten. Die Diagnostik gilt als Herausforderung, die Latenz vom Beginn erster Symptome bis zur Diagnosestellung...

Common Femoral Artery Curvature During Hip Flexion
Purpose: To assess the conformational changes of the common femoral artery (CFA) during hip joint flexion in patients without atherosclerosis. Methods: Patients who underwent digital subtraction angiography for suspicion of arterial endofibrosis...

Anatomic Factors Contributing to External Iliac Artery Endofibrosis in High-Performance Athletes
Background: External iliac artery endofibrosis (EIAE) classically presents in cyclists with intimal thickening of the affected arteries. We investigated possible anatomical predisposing factors including psoas muscle hypertrophy, arterial tortuosity,...

Exercise induced leg pain due to endofibrosis of external iliac artery
Due to monotonous movement patterns, muscular hypertrophy, and increased cardiac output peripheral vasculature of athletes are subject to extreme stresses during athletic performance. Individuals suffering from exercise induced non-traumatic lower leg...

Claudicatio des jungen Menschen Vaskuläre Kompressionssyndrome der unteren Extremität
Die Claudicatio beim jungen Menschen ist eine seltene Entität. In Abwesenheit bekannter Risikofaktoren der Atherosklerose ist die klassische periphere arterielle Verschlusskrankheit (pAVK) als Ursache eher unwahrscheinlich. An Differenzialdiagnosen...

Peripheral Vascular Imaging Focusing on Nonatherosclerotic Disease
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,...

Gefäßerkrankungen bei Triathlete
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
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...
-
MRI to investigate iliac artery wall thickness in triathletes
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
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.

Color Doppler Ultrasound Imaging in the Assessment of Iliac Endofibrosis
Endofibrosis (EF) of the iliac arteries is a flow-limiting condition typically seen in highly trained endurance athletes. Thirty-seven athletes (74 limbs) were referred to our department with suspected EF. All patients had a pre- and postexercise color...
-
Arterial endofibrosis in endurance athletes: angiographic features and classification
Purpose: To describe the spectrum of angiographic features of arterial endofibrosis and to assess the patterns of associated lesions. Materials and methods: This retrospective study was compliant with the declaration of Helsinki principles. Files of...
-
Iliac blood-flow restrictions causing painful and "powerless" legs are often attributed to overtraining and may develop for some time before being correctly diagnosed. In the current study, differences between actual performance parameters and...
-
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...

Isquemia crónica dos membros inferiores, de etiologia não aterosclerótica, em desportistas jovens
Although rare, the iliac endofibrosis and the popliteal artery entrapment syndrome are undoubtfully recognized as causes of intermittent claudication in young patients, particularly in athletes. The authors report the clinical case of a young female...
-
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...
-
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...
