Recurrent giant sinus of Valsalva aneurysm and ankylosing spondylitis.

A 48-year-old woman underwent aneurysmectomy and primary suture repair with a pericardial patch for sinus of Valsalva aneurysm secondary to ankylosing spondylitis. The sinus of Valsalva aneurysm recurred one year after surgery, and reached a diameter of 53 mm. Special attention must be paid to the potential relapse of aortic aneurysms that develop secondary to autoimmune disorders, when using primary suture or patch repair.
