UNASSIGNED: Extra-cranial carotid @entity438 (ECAA) are uncommon and represent a therapeutic challenge for clinicians. An ECAA is generally defined as a @entity3538 (CCA) greater than 150% of the diameter of the normal healthy artery. The presence of an ECAA is usually found by coincidence in asymptomatic @entity1 . Symptomatic @entity1 may present with @entity51 or symptoms of local compression. The initial diagnosis of ECAA is often by echo/duplex ultrasound imaging. However, Computerized tomographic angiography (CTA), with 3- dimensional reconstruction of the images (3D) can provide additional and valuable information, especially when considering surgical exclusion of the @entity439 . Recently, vessel wall imaging using contrast enhanced Magnetic Resonance with @entity2287 administration was explored, which could potentially provide valuable information regarding @entity439 wall changes during clinical follow up. Location and accessibility of an ECAA is key information when considering the appropriate treatment. With the lack of evidence based treatment guidelines, a conservative approach with or without medicinal treatment is currently the standard of care for asymptomatic non-growing ECAA. Open surgical repair has for long been the accepted treatment for @entity1 with a growing @entity439 or @entity439 related symptoms. Endovascular interventions are increasingly applied, especially when surgical intervention is considered too risky or not possible due to @entity1 comorbidities or anatomical restrictions. Data on the natural course, immediate and long-term results of surgical or endovascular therapy is scarce. Thus, there is a clear need for an international collaboration collecting data of ECAA within a registry.
