An angiogram is a diagnostic procedure that provides detailed, x-ray pictures of the heart and blood vessels. We definitely need angiogram in the diagnosis of which of the following:

  • Coronary artery disease.
  • Renal artery stenosis.
  • Peripheral artery disease.
  • Carotid artery stenosis.
  • Subarachnoid hemorrhage.
  • None of the above.

The correct answer is none of the above. We angiogram in all of these condition for anatomical location of the lesion not the diagnosis.

In CAD not to diagnose the disease, but to see the anatomical site of the blockage, ex if the Lt main, or three vessels disease to tell you whether to do surgery or not. In renal artery stenosis you need angiogram to determine the anatomic location, before angioplasty and stent. In peripheral artery disease: diagnosed by ankle brachial indexes, and look for decrease in ratio greater than 0.9. You do angiogram to determine the site of the bypass. Carotid stenosis- diagnosed by duplex sonogram-you do angiogram to determine the diameter in order to guide the endarterectomy. Subarachnoid hemorrhage is diagnosed by CT without contrast & the most accurate test is the lumber puncture. Angiogram in SAH to know the site of bleeding not to diagnose SAH, to stop it surgically (clipping) or by embolization.:indifferent:
