CTICasesAnastomotic Pseudoaneurysm after Aortic Aneurysm Repair in Marfan Syndrome
Imaging findings
CT chest of a patient with Marfan syndrome who previously underwent ascending aortic aneurysm repair shows postoperative fluid surrounding the graft. One year later, follow-up CT reveals development of a distinct pseudoaneurysm arising at the distal suture line (distal anastomosis) due to persistent, uncontrolled hypertension.
Key takeaways
Patients with connective tissue disorders like Marfan syndrome are highly susceptible to anastomotic dehiscence, leak, and pseudoaneurysm formation after aortic reconstruction. Strict blood pressure control is paramount in the post-operative period to prevent mechanical stress on suture lines and minimize the risk of late vascular complications.
