Aorto-femoral angiography carried out in 839 patients revealed that 139 males and females had uni- or bilateral occlusion of the common or external iliac arteries. Pelvic or lumbar/intercostal arteries served as collaterals in 786 patients. In the remaining 53 patients the collateral blood supply originated from the thoracic arteries. Among the 53 patients, only 7 were females. A chi 2-test revealed the difference to be significant (p less than 0.0005), indicating a sex-linked difference, a male preponderance, in the development of collateral circulation of thoracic origin.
对839例患者进行的主-股动脉血管造影显示，139例男性和女性存在单侧或双侧髂总动脉或髂外动脉闭塞。786例患者中，盆腔或腰/肋间动脉作为侧支循环。其余53例患者的侧支血供源自胸段动脉。在这53例患者中，仅7例为女性。卡方检验显示差异具有显著性（p<0.0005），表明在源自胸段的侧支循环形成中存在性别关联差异，男性占优势。
