Catheter-induced straightening of external iliac tortuosity: a cause of pseudostenosis to be borne in mind.
Reversible vascular obstructive lesions, i.e. pseudostenoses, may pose significant threats to interventional cardiologists as they can be mistaken for obstructive lesions and prompt inappropriate revascularization procedures. We hereby report for the first time in the literature a case of external iliac artery pseudostenosis due to catheter straightening of significant underlying vessel tortuosities. Despite the initial angiographic image obtained from retrograde catheterization of the right external iliac artery which was strongly suggestive for significant stenosis, a thorough review of clinical history, physical examination and a second-look angiography by means of contralateral catheterization and contrast injection showed the absence of any significant lesion in the tortuous left external iliac artery, thus avoiding an unnecessary and potentially harmful vascular intervention. This clinical vignette emphasizes the importance of a thorough clinical examination and angiographic assessment for the appropriate diagnosis and management of reversible stenoses.
