Myelography is generally safe with few complications. Most practitioners screen for certain drugs but do not require discontinuation of metformin or NSAIDs, nor routinely check coagulation times.

Area of Science:

  • Neuroradiology
  • Medical Imaging Safety

Background:

  • Limited data exist on postmyelography complications.
  • No consensus on pre-procedure screening for epileptogenic drugs, metformin, aspirin/NSAIDs, or coagulation tests (PT/PTT).

Purpose of the Study:

  • To survey current practice patterns regarding myelography complications.
  • To gather data on screening protocols and complication rates.

Main Methods:

  • A web-based survey was emailed to 2,296 American Society of Neuroradiology members.
  • 351 responses (15% participation rate) were analyzed.

Main Results:

  • 88% reported no postmyelography seizures; 82% observed no other significant complications.
  • 63% screen for epileptogenic drugs; a majority do not stop metformin or NSAIDs.

  • 73% do not routinely check PT and PTT.

    • Conclusions:

    • Myelography demonstrates a low risk of seizures and other significant complications.
    • Current practices of screening for some drugs but not routinely stopping others or checking coagulation are deemed appropriate.
    • Established practice patterns support safe and efficient myelography.
