Case Study / Supporting Documentation Submission & Review

Once the application is submitted via Online Accreditation, five case studies from the submitted procedure log will be randomly selected by the IAC. The Medical Director and Technical/Administrative Director will be notified that the application was received and which procedures have been selected for submission.

Once your facility has been notified by the IAC of the five randomly selected case studies, upload all requested case study documents (reports) in the online application; then, upload the requested case study images in a DICOM format with the DICOM viewer to ImageShare. Refer to the information below that outlines the requested materials for each case study:

Pre-Carotid Artery Stent Procedure:

  • Report(s) of noninvasive diagnostic imaging test(s) performed (e.g., duplex, CTA, MRA)
  • Report(s) of invasive diagnostic imaging test (carotid/cerebral angiography)
  • NIHSS neurologic assessment results
  • mRs neurologic assessment results
  • Patient history and physical documentation

Carotid Artery Stent Procedure:

  • CAS procedure report
  • Nurse / anesthesia monitoring report during the procedure
  • NIHSS neurologic assessment results performed post procedure (within ~24 hours)
  • mRS neurologic assessment results performed post procedure (within ~24 hours)

30-Day Follow Up (~21 to 60 days):

  • NIHSS results performed within 21 to 60 days
  • mRS results performed within 21 to 60 days
  • Report(s) from diagnostic imaging test(s) (e.g., duplex ultrasound) performed within 21 to 60 days

If a selected case study is for a patient who had a post stenting complication (stroke/death), include an explanation of the complication, the follow up procedures, and procedural CAS procedure changes to prevent reoccurrence of this specific complication (if applicable).

Case Study Images

Pre-stent placement:

  • image(s) of the arterial stenosis that best demonstrate the degree of stenosis and display the measurement of the degree of stenosis using electronic calipers
  • intracranial arterial phase frontal (AP) and lateral digital subtracted angiography (DSA) images

Post-stent placement:

  • intracranial arterial phase frontal (AP) and lateral digital subtracted angiography (DSA) images
  • image(s) of the stented arterial region that best demonstrates the degree of stenosis

Case study materials must be uploaded and submitted within 30 business days following notification by the IAC of which procedures were selected.

Case Study Review Process

Once the case study has been uploaded and submitted online, the IAC Carotid Stenting staff will implement the review process to evaluate the submitted case studies. An accreditation decision will be rendered within 8-12 weeks from the date case studies are submitted.
