OBJECTIVES:
High performance cyclists develop external iliac arteriopathy after years of exercise, but it is unclear if anatomic variation contributes to this condition. We hypothesized that the length of the external iliac artery (EIA) and the ratio of EIA to total iliac length (rEIA) would vary between symptomatic cyclists and healthy control patients.
METHODS:
Cyclists with pre-operative CTA or angiography who underwent EIA reconstruction between Oct 2004 and Dec 2013 were compared to non-cyclists with similar imaging identified from a trauma database. Measurements for symptomatic limbs were compared to contralateral unaffected limbs, and to gender-matched controls using matched pairs analysis and independent t-tests. Calculations were performed including and excluding outliers greater than 3 standard deviations from the mean to assess any skewing of data.
RESULTS:
Thirty-seven cyclists were compared to 39 controls. In 25 cyclists with unilateral symptoms, a matched pairs analysis showed no significant difference in EIA length (p=0.36) or rEIA (p=0.27) between affected and unaffected limbs. Of 21 female cases and 13 controls, there was also no difference in EIA length (p=0.41 right leg, p=0.50 left leg) or rEIA (p=0.543 right, p=0.81 left). Additionally, there was no difference in the EIA length (p=0.48 right leg, p=0.37 left leg) or rEIA (p=0.49right, p=0.89 left) in the 16 male cyclists compared to the 26 controls. There was no difference in artery length between those who received interposition grafts and those who had patch angioplasty (EIA length p=0.95, rEIA p=0.82).
CONCLUSIONS:
In our patient population, no differences exist in artery length or ratio of length, suggesting that artery length discrepancy is not a cause of external iliac arteriopathy in cyclists. EIA length and rEIA in affected limbs of cyclist do not differ from the measurements in contralateral unaffected limbs or those of gender-matched controls. Artery length did not influence method of surgical repair.
