IN-STENT STENOSIS Figure 5-28 IN-STENT STENOSIS This section, obtained using a diamond microtome, revealed complete luminal occlusion by chronic (fibrotic) thrombosis. The stent struts can still be seen, well opposed, at the periphery of the artery. More about this image found in IN-STENT STENOSIS This section, obtained using a diamond microtome, reveal...

TAKAYASU DISEASE Figure 30-8 TAKAYASU DISEASE In this case of abdominal involvement with stenosis, there is narrowing of the abdominal aorta (yellow arrow) with intimal wrinkling, imparting a “tree bark” appearance. The descending thoracic aorta, proximally, is less involved. More about this image found in TAKAYASU DISEASE In this case of abdominal involvement with stenosis, ther...
