  • Title: [Para-anastomotic Aneurysm in the Ascending Aorta Late After Aortic Valve Replacement:Report of Two Cases].
    Author: Ito M, Wakamatsu Y.
    Journal: Kyobu Geka; 2024 Aug; 77(8):586-589. PubMed ID: 39205411.
    Abstract:
    Case 1 was a 59-year-old man who underwent aortic valve replacement (AVR) at the age of 38, for aortic regurgitation. Case 2 was a 51-year-old man who underwent AVR at the age of 34, for aortic regurgitation. Both cases required surgery for ascending aortic aneurysms. These patients showed aneurysm at the site of the prior aortotomy. In both of the patients used felt-strip was used for closing aortotomy. Intraoperative findings showed enlargement of the aorta around the felt-strip, which was a finding of true aneurysm. Both cases underwent ascending aortic replacement. The mechanism of aortic aneurysm development was thought to include persistent mechanical stimulation by the felt-strip and ischemia of the vasa-vasorum due to compression of the felt-strip. The use of felt-strips for the aortotomy suture should be avoided, especially in young patients.
