MR Angiography Upper Extremity - CAM 701

Description
Magnetic resonance angiography (MRA) is a noninvasive alternative to catheter angiography for evaluation of vascular structures in the upper extremity. Magnetic resonance venography (MRV) is used to image veins instead of arteries. MRA and MRV are less invasive than conventional X-ray digital subtraction angiography.

OVERVIEW
UPPER EXTREMITY DVT — "Secondary DVT of the upper extremity is by far the most common type. Indwelling venous devices such as catheters, pacemakers, and defibrillators put patients at the highest risk of thrombus. Central venous catheters, which are difficult to place, such as those requiring multiple insertion attempts, are noted to have increased incidence of associated thrombus [9]. Other risk factors associated with higher likelihood of UEDVT include advanced age, previous thrombophlebitis, postoperative state, hypercoagulability, heart failure, cancer, right-heart procedures, and intensive care unit admissions" (ACR, 2014).

MRA/MRV and Raynaud’s Syndrome — Raynaud’s syndrome is evidenced by episodic waxy pallor or cyanosis of the fingers caused by vasoconstriction of small arteries or arterioles in the fingers. It usually occurs due to a response to cold or to emotional stimuli. MRA may be used in the evaluation of Raynaud’s syndrome.

MRA/MRV and Stenosis or Occlusion — MRA of the central veins of the chest is used for the detection of central venous stenoses and occlusions. High-spatial resolution MRA characterizes the general morphology and degree of stenosis. Enlarged and well-developed collateral veins in combination with the non-visualization of a central vein may be indicative of chronic occlusion, whereas less-developed or absent collateral veins are suggestive of acute occlusions. A hemodynamically significant stenosis may be indicated by the presence of luminal narrowing with local collaterals (Conte, 2019; Kim, 2008). 

MRA and Arterial Obstructive Disease — Catheter angiography is the standard of reference for assessing arterial disease but MRA with contrast enhanced media has gained acceptance and can image the entire vascular system. Contrast agents such as high dose gadolinium have been associated with the development of nephrogenic systemic fibrosis in patients with chronic renal insufficiency, but newer agents are safer in this regard. Gadolinium dosage may be decreased without compromising image quality in high-spatial-resolution contrast-enhanced MRA of the upper extremity.  

Policy
UPPER EXTREMITY MRA/MRV Is considered MEDICALLY NECESSARY for the following indications:

INDICATIONS FOR UPPER EXTREMITY MRA/MRV

Hand Ischemia: (Bae, 2015; Hotchkiss, 2014; Wong, 2016)

  • Arterial Doppler not needed with any of these acute symptoms:
    • Ischemic ulceration without segmental temperature change.
    • Ischemic ulceration with painful ischemia.
    • Acute sustained loss of perfusion with or without acral ulceration.
    • Imminent loss of digit.
  • Clinical symptoms without the above features, arterial Doppler abnormal and will change management
    • Includes Raynaud’s (can be associated with scleroderma), Buerger disease and other vasculopathies (McMahan, 2010)
  • Clinical concern for vascular cause of ulcers with abnormal or indeterminate ultrasound (Rosyd, 2017)
  • After stenting or surgery with signs of recurrence or indeterminate ultrasound (Pollak, 2012)

Deep Venous Thrombosis or Embolism: (Dill, 2014; Heil, 2017) 

  • After abnormal ultrasound of arm veins if it will change management, or negative or indeterminate ultrasound to rule out other causes
  • For evaluation of central veins
  • Clinical suspicion of upper arterial emboli (Bozlar, 2014)

Clinical suspicion of vascular disease with abnormal or indeterminate ultrasound or other imaging (Boziar, 2013)

  • Tumor invasion (Jin, 2018; Kransdorf, 2018)
  • Trauma (Wani, 2012)
  • Vasculitis (Fonseca, 2017; Hotchkiss, 2014)
  • Aneurysm (Verikokos, 2014)
  • Stenosis/occlusions (Menke, 2010)  

Vascular Malformation (Madani, 2015; Obara, 2019)

  • Non diagnostic doppler ultrasound

Pre-operative/procedural evaluation:

  • Pre-operative evaluation for a planned surgery or procedure (Ahmed, 2017).

Post-operative/procedural evaluations: 

  • A follow-up study may be needed to help evaluate a patient’s progress after treatment, procedure, intervention or surgery. Documentation requires a medical reason that clearly indicates why additional imaging is needed for the type and area(s) requested.

Special Circumstances (Weiss, 2017):

  • High suspicion of an acute arterial obstruction - Arteriography preferred (the gold standard).
  • Renal impairment
    • Not on dialysis
      • Mild to moderate, GFR 30-89 ml/min MRA can be done
      • Severe, GFR < 30 ml/min MRA without contrast
    • On dialysis
      • CTA with contrast can be done
  • Doppler ultrasound can be useful in evaluating bypass grafts

All other uses of this technology are investigational and/or unproven and therefore considered NOT MEDICALLY NECESSARY.
