Neurointerventional procedures are increasing in both number and complexity. The risks of increased exposure to radiation are therefore of increasing concern, particularly as more complex lesions are treated, requiring longer fluoroscopic time and increased radiation exposure. Both acute and long-term effects of increasing radiation exposure are of equal importance. One practical method to decrease fluoroscopy time and exposure would be universal manufacturing and subsequent practitioner adoption of fluoroscopy-marked catheter tips. The purpose of this study was to assess what percentage of available neurointerventional devices had such external markers.
Materials and methods
Vendors producing neurointerventional devices intended for intracranial navigation were contacted for a list of their available products, and whether or not they included an external marker on the delivery shaft to indicate when to …
