Principles of label use of medication and/or devices in neuroendovascular procedures
Principles
  1. Identify off-label use and understand the use according to label/indications
  2. Categorize the off-label use according to categories presented in the On-line Table
  3. Category III requires informed consent for medication/device use with a description of adverse events observed in neurovascular procedures
  4. Category IV requires informed consent for medication/device use with a description of adverse events observed in non-neurovascular procedures and acknowledgment of paucity of data from neurovascular procedures
