CTICasesCabrol Patch (Surgical Aortic Root Hemostatic Wrap)
Imaging findings
Post-operative CTA after ascending aortic repair for dissection demonstrates a large fluid/blood-containing collection surrounding the aortic root, connected to the right atrium, with a contained area of contrast material within it. The pericardium appears thickened. The collection represents an intentional surgical construct (Cabrol patch) in which a pericardial or Dacron patch was sewn around the aortic root to contain intraoperative bleeding and drain it into the right atrium.
Key takeaways
The Cabrol patch is a surgical technique used during complex aortic root operations to manage intraoperative hemorrhage. A pericardial patch is sewn around the aortic root and connected to the right atrium to create a controlled drainage pathway for bleeding. On post-operative CT, it appears as a large contrast-containing collection around the aortic root with communication to the right atrium, and should not be mistaken for a pseudoaneurysm, infection, or contained rupture.
