Case Study Requirements - Vascular Testing

Extracranial Cerebrovascular

Submit three representative abnormal case studies.   

  • All must be bilateral testing and demonstrate >50% ICA stenosis.

Intracranial Cerebrovascular

Submit three representative abnormal case studies.   

  • Must submit one abnormal complete physiologic or duplex intracranial examination assessing MCA, ACA, PCA, TICA, siphon vertebral and basilar arteries
  • If performed, must submit one abnormal vasospam examination.
  • Additional abnormal representative case studies must be chosen from the options above or those listed below:

    • Emboli detection examination
    • Vasomotor reactivity examination
    • Right-to-left shunt examination
    • Assessment of cerebral circulatory arrest

Peripheral Arterial

Submit three representative abnormal case studies.  

  • If performed: Must submit one lower extremity arterial duplex examination (bilateral or unilateral) that must demonstrate >50% stenosis and include bilateral ABI. The case can include a stent or bypass graft.
  • If performed: Must submit one complete bilateral lower extremity non-imaging multilevel waveform physiologic examination
  • Additional abnormal representative case studies must be chosen from the options above or those listed below.

    • Native AAA examination (without previous repair)
      Comment: This examination is only an option in one testing area and cannot be submitted if already submitted in visceral vascular.
    • Dialysis access graft/AVF duplex
      Comment: This examination is only an option in one testing area and cannot be submitted if already submitted in peripheral venous.
    • Upper extremity arterial duplex examination (bilateral or unilateral) that demonstrates >50% stenosis.

Peripheral Venous

Submit three representative abnormal case studies, all can be unilateral.

  • If performed: Must submit one lower extremity venous patency/DVT examination.
  • If performed: Must submit one lower extremity venous reflux examination (must be pre-intervention).
  • Additional abnormal representative case studies must be chosen from the options above or those listed below. Only one case may be vein mapping.

    • Dialysis access graft/AVF duplex examination
    • Upper extremity patency/DVT examination
    • Upper or lower extremity vein mapping

Visceral Vascular

Submit three representative abnormal case studies.

  • If performed: Must submit one complete bilateral renal artery examination with >60% stenosis, can include a stent.
  • If performed: Must submit one complete mesenteric artery examination with >50% stenosis, can include a stent.
  • Additional abnormal representative case studies must be chosen from the options above or those listed below. Only one case may be native AAA examination (without previous repair).

    • Hepatoportal duplex
    • Renal transplant duplex
    • Liver transplant duplex
    • Native AAA examination (without previous repair)
      Comment: This examination is only an option in one testing area and cannot be submitted if already submitted in peripheral arterial.

Screening

One case study for each type of screening performed: Extracranial, ABI, AAA and CIMT.
These cases studies can be normal.

Multiple Sites

Submit one representative abnormal case study.
