Gross processing

A minimal gross processing of arteries includes a longitudinal dissection and inspection of tunica intima.

Consecutive cross-sections allows for a detection and estimation of atherosclerotic stenosis.

Plaque at different degrees of atherosclerotic stenosis.

Microscopic examination

  • Confirm that it is actually an artery (may be a vein, and a neuron may look grossly like a small artery).
  • Look for atherosclerosis and thrombosis.
  • Classify atherosclerosis as mild, moderate or severe.
  • If cross-sections were made, estimate the maximum percentage of occlusion for each artery.
Evaluate for giant cell arteritis at least upon request. It is characterized by a granulomatous inflammation of arteries with discontinuous and fragmented internal elastic lamina.[2]

Microscopy report

  • Classify any atherosclerosis as mild, moderate or severe.
  • If cross-sections were made, state the maximum percentage of stenosis for each artery.

Example:

Sections of the three main coronary arteries reveal << mild / moderate / severe>> atherosclerosis, with approximately __%, __% and __% stenosis of the left anterior descending, left circumflex coronary artery and right coronary artery, respectively.
