CTICasesTakayasu's Arteritis with Aortic Arch Thickening and Multiple Surgical Grafts

Imaging findings
CT angiography showed circumferential soft tissue thickening around the descending aorta and aortic arch, characteristic of Takayasu's arteritis. There were absent or abnormally originating arch vessels, and evidence of multiple prior surgical interventions including a thrombosed, failed graft and a new long graft connecting the aortic arch to the axillary artery.
Key takeaways
Takayasu's arteritis is a chronic inflammatory disease primarily affecting the aorta and its major branches, typically seen in younger patients. Imaging characteristically shows aortic wall thickening. The disease can lead to stenosis, occlusion, or aneurysm formation in the affected vessels, often requiring complex surgical revascularization, as seen with multiple failed and successful grafts in this case. The question of whether aortic wall thickening regresses with treatment was raised, with anecdotal evidence suggesting improvement but not complete resolution.
