Abstract

Asendan aort psödoanevrizması kardiyak
cerrahinin nadir fakat ölümcül komplikasyonlarından biridir. Genellikle
infeksiyon, önceki bağ dokusu bozuklukları, aort kanülasyonu, safen greft
anastomoz proksimal bölgesi veya aortotomi sütür hattı, aortik klemp bölgesi
gibi çeşitli faktörler asendan aort psödoanevrizma ile ilişkili zemin
hazırlayan faktörlerdir. Biz koroner arter baypas cerrahisinden 7 yıl sonra
safen ven proksimal anastomozu ile ilişkili asendan aort psödoanevrizması
gelişen olguyu sunduk. Bu hastalarda anevrizma rüptürünün ölümle
sonuçlanabilmesi nedeniyle takip döneminde zamanında anevrizmanın  saptanması, 
etkili cerrahi tekniğin uygulanması ve perioperatif ve postoperatif
dönemde hastaların başarılı yönetimi esastır.

Ascending Aortic Pseudoaneurysm After Coronary Artery Bypass Grafting

Abstract

Ascending aortic pseudoaneurysm is a rare but
fatal complication of cardiac surgery. Predisposing factors associated with
ascending aortic pseudoaneurysms are usually related to several factors such as
infection, prior connective tissue disorders, aortic cannulation, the proximal
site of graft anastomosis or the suture line of aortotomy and the aortic clamp
site. We present a case of an ascending aortic pseudoaneurysm developed 7 years
after coronary artery bypass grafting associated with the proximal anastomosis
of a saphenous vein graft. It is essential to diagnose the aneurysm in a timely
manner during follow-up, to employ effective surgical techniques and to successfully
manage the patients during the perioperative and postoperative periods because
rupture of the aneurysm could result in death in these patients.
