| Takayasu’s Arterirtis |
| The series of images are from the angiogram of a 14 year old female who presented with seizures and an elevated blood pressure. Images a and b show multiple stenoses within the carotids best seen at the level of the bifurcation into external and internal arteries. In addition in b, the aortic arch shows non critical narrowing just after the origin of the left common carotid vessel. Note that the right subclavian artery is not seen and presumably is accluded at its origin. The abdominal angiogram shows a significant narrowing of the left renal artery with post stenotic dilitation, and stenotic disease in the infrarenal abdominal aorta. The multicentric nature of the disease in a young female is athognomonic of Takayasu’s arteritis. 35155c Courtesy of Laura Feldman MD. code CVS artery aorta arteritis inflammation Takayasu’s carotid thorax arch renal abdomen pulseless |
| Polyarteritis Nodosa |
| Occlusive Vascular Disease: Causes of Vascular Occlusion – Polyarteritis Nodosa. This is a medium power photomicrograph from a bowel in a patient with Polyarteritis Nodosa. Bowel is commonly affected in this disorder. The medium sized artery seen here has undergone a deeply eosinophilic (fibrinoid) change. Notice that there is a surrounding inflammatory infiltrate of WBCs and formation of aneurysmal dilatation. This can result in massive hemorrhage if the aneurysm ruptures. colon large bowel artery small bowel fx aneurysm inflammation dx polyarteritis nodosa histopathology Courtesy Barbara Banner MD 12889 |
