“…Table 1 shows that the lesions of the external γ of twenty-five cyclists included in the study, there were twenty-seven cases, as two cyclists (1 man and 1 woman) were studied at two different time points and in contralateral limb to the one affected before: 15• l , ten men and five women -8• r , two men and six women, and 4• l,r , three men and one woman. reality of cyclists during training or competitions more closely 7,9,12,66 . Placing the cuff while the patient is pedaling is difficult, and, therefore, blood pressure measurements are made immediately after the effort, at 30 seconds or in the first minute, while the patient is lying supine 67 .…”

“…Tortuosity with kinking generated by hip hyperflexion 3,9,22,[27][28][29][30]36,39,62,71 (Figure 2a, b) and artery compression due to psoas muscle and inguinal ligament hypertrophy during pedaling 3,27,29,36,39,61,71,72 are, according to the literature, the factors responsible for blood flow reductions. For this reason, the excision of this ligament is common in patients with vascular compression (e.g., external iliac and common femoral arteries) in the inguinal region 9,49,57,58,60.

“…In the last twenty years, several cases of cyclists with vascular dysfunction in the lower limbs have been diagnosed. This condition may trigger exercise-induced pain, edema, loss of power and, consequently, a poorer performance [7][8][9] , signs and symptoms previously associated exclusively with musculoskeletal lesions while the possibility of arterial insufficiency was overlooked 10,11 . This review investigated the occurrence of vascular dysfunctions of the lower limbs in cyclists, a topic of great importance in sports medicine, as healthcare professionals are not familiar with this type of dysfunction, which may lead to late diagnoses and, consequently, greater morbidity.…”

Sports-related vascular insufficiency affecting the lower limbs is uncommon, and early signs and symptoms can be confused with musculoskeletal injuries. This is also the case among professional cyclists, who are always at the threshold between endurance and excess training. The aim of this review was to analyze the occurrence of vascular disorders in the lower limbs of cyclists and to discuss possible etiologies. Eighty-five texts, including papers and books, published from 1950 to 2012, were used. According to the literature reviewed, some cyclists receive a late diagnosis of vascular dysfunction due to a lack of familiarity of the medical team with this type of dysfunction. Data revealed that a reduced blood flow in the external iliac artery, especially on the left, is much more common than in the femoral and popliteal arteries, and that vascular impairment is responsible for the occurrence of early fatigue and reduced performance in cycling.Keywords: cycling; peripheral arteriopathy; blood flow; stenosis. ResumoO desenvolvimento de insuficiência vascular em membros inferiores relacionada à prática esportiva é incomum e no início do surgimento dos sinais e sintomas frequentemente pode ser confundida com lesão musculoesquelética, a exemplo de casos relatados em ciclistas profissionais, por estarem sempre no limiar entre o treinamento em nível máximo e o excesso de treinamento. O objetivo desta revisão de literatura foi analisar a ocorrência de disfunções vasculares em membros inferiores em ciclistas e as possíveis etiologias. Oitenta e cinco textos, entre artigos e livros publicados de 1950 a 2012 foram utilizados. Segundo a literatura, alguns ciclistas têm o diagnóstico de disfunção vascular realizado tardiamente devido à falta da familiaridade da equipe médica com esta modalidade de disfunção. Os resultados da pesquisa revelaram que a redução do fluxo sanguíneo na artéria ilíaca externa, em especial a esquerda, é bem mais comum que a da artéria femoral e poplítea, e que o comprometimento vascular é responsável pela ocorrência de fadiga precoce e redução do desempenho no ciclismo.Palavras-chave: ciclismo; arteriopatia periférica; fluxo sanguíneo; estenose.

Zusammenfassung 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 beträgt oft mehrere Jahre. An diagnostischen Möglichkeiten sind die Bestimmung des Knöchel-Arm-Dopplerindex (ankle brachial index, ABI) nach maximaler Belastung als ein nicht invasives Verfahren sowie die Duplexsonografie, Schichtbildgebung und die invasive Angiografie zu nennen. Ziel dieser Arbeit ist es, diese zeitliche Verzögerung bis zur korrekten Diagnosestellung seit Erstbeschreibung im Jahr 1985 bis zum Jahr 2021 genauer zu analysieren sowie die wichtigsten diagnostischen Mittel für die Praxis herauszuarbeiten. Methode Durchführung einer Literaturrecherche gemäß den PRISMA-Kriterien in den Datenbanken PubMed, Web of Science und Cochrane, ergänzt durch eine Suche in Google Scholar bis zum 18.10.2021. Ergebnisse Es wurden 133 Publikationen identifiziert, die sich thematisch mit der IE bei Ausdauersportlern beschäftigten. In 42 Publikationen (40 Fallberichte und 2 klinische Studien) wurde die Diagnose intraoperativ bestätigt, in 32 (32/43; 74,4%) wurden Aussagen über die Dauer vom Auftreten der ersten Symptome bis zur Diagnosestellung gemacht (Mittelwert 45, Median 36 Monate). Diese Latenz war über den gesamten Beobachtungszeitraum von 1985–2021 konstant, ohne Trend zur Verkürzung. In 24 Arbeiten (24/43; 56%) wurde detailliert über Ergebnisse der ABI-Bestimmung sowie der weiterführenden Diagnostik berichtet. In allen Fällen kam es zu einem Abfall des ABI- Wertes auf weniger als 0,66 (in 5 Fallberichten bereits in Ruhe, in 19 nach Belastung), wohingegen die weiterführende Diagnostik mittels Duplexsonografie, DSA, MRA oder CTA in 3 Fällen (3/24; 12,5%) keinen auffälligen Befund ergab und in 14 Fällen (14/24; 58,3%) eine allenfalls geringgradige Stenosierung zeigte. Schlussfolgerung Ein Abfall des ABI nach Belastung ist die zuverlässigste Methode, um die iliakale Endofibrose zu diagnostizieren. Es empfiehlt sich, diese nicht invasive und einfach durchführbare Untersuchung in die Leistungsdiagnostik gefährdeter hochambitionierter Ausdauerathleten zu integrieren, um im Idealfall durch eine frühzeitige Diagnosestellung irreversible Gefäßwandschäden zu verhindern sowie die vermutete hohe Dunkelziffer an unerkannten Fällen zu reduzieren.
