 Large partially thrombosed pseudoaneurysm is identified in the region of graft and surgery related to CABG along ascending aorta.

 Pseudoaneurysms can arise proximally or distally along grafts most commonly at the anastomotic sites. CTA can evaluate extent of any partial thrombosis. If there is continued increase in size or if it is large enough, it would require surgical correction. 

Pseudoaneurysms are associated with infection or leak. Coil occlusion or covered stents are common interventions to treat, as well, especially in high-risk patients.
