Abstract

Background: We intended to outline the pathological changes and the etiology of the ascending aortic dilatation, based on the histopathological findings in patients who received the replacement of the dilated ascending aorta. Methods: Ascending aortic replacement was accomplished in 24 (16 male, 8 female, mean age 57.5 ± 8.5) consecutive patients in our center. Mean measured, predicted aortic diameters and aortic ratio were found 5.0 ± 0.5 cm, 2.8 ± 0.1 cm, 1.8 ± 0.2 respectively. Hypothermic cardiopulmonary bypass (mean 224 ± 82 min.), cardioplegic arrest (mean 106 ± 59 min.) and deep hypothermic circulatory arrest (22 patients, mean 19.9 ± 4.8 min.) were utilized. Concomitant cardiac procedures were performed in 21 patients. Histopathological examination of the aortic specimen was performed in 23 patients. Results: Medial degeneration (n = 14) or atherosclerotic degeneration (n = 9) was observed in histopathological examination. Age, gender, aortic diameter, aortic ratio, history of smoking, presence of hypertension and bicuspid aortic valve were compared between the patients falling into two histopathological definitions. These demographic and clinical data did not differ significantly. Cardiovascular diseases were not significantly different between the patients with either of these pathologies. Conclusion: Dilated ascending aorta is associated with medial degeneration or atherosclerotic degeneration of the aortic wall. Clinical and demographic characteristics of patients having these pathologies are not different. Both pathologies can be observed with isolated dilatation of the ascending aorta or with dilatation of the ascending aorta associated with aortic valve and/or coronary heart disease.

Özet

Amaç: Bu çalışma çıkan aort dilatasyonu tamiri uyguladığımız vakalarda elde edilen bulgular zemininde histopatolojik değişiklikleri ve etiyolojik etmenleri irdelemek amacıyla yapıldı. Materyal ve Metod: Kliniğimizde, Ağustos 1999 ve Haziran 2002 döneminde, 24 ardışık hastada (16 erkek, 8 kadın, yaş ortalaması 57.5 ± 8.5) çıkan aort replasmanı yapıldı. Ortalama aort çapı, öngörülen aort çapı ve aort oranı sırasıyla 5 ± 0.5 cm, 2.8 ± 0.1 cm ve 1.8 ± 0.2 bulundu. Ameliyatlarda hipotermik kardiyopulmoner bypass (224 ± 82 dak), kardiyoplejik arrest (106 ± 59 dak), total sirkülatuar arrest (22 hasta, 19.9 ± 4.8 dak) kullanıldı. 21 hastada ek olarak kardiyak girişim uygulandı. Çıkarılan aort dokusunda histopatolojik inceleme yapıldı (n = 23). Bulgular: İncelemede 14 hastada medial dejenerasyon, 9 hastada aterosklerotik dejenerasyon gözlendi. Bu iki histopatolojik bulgunun saptandığı hastalar arasında yaş, cins, aort çapı, aort oranı, sigara kullanımı, hipertansiyon ve biküspid aort varlığı karşılaştırıldı. Karşılaştırmada demografik ve klinik veriler arasında istatistiksel olarak anlamlı fark bulunamadı. Ayrıca medial dejenerasyon ve aterosklerotik dejenerasyon saptanan hastalardaki kardiovasküler hastalıklar arasında anlamlı fark saptanamadı. Sonuç: Çıkan aortun dilatasyonu histolojik düzeyde ağırlıklı olarak medial dejenerasyon veya aterosklerotik dejenerasyon ile birlikte görülmektedir. Her iki patolojik farklılaşma izole aort dilatasyonu veya aort dilatasyonuna eşlik eden aort kapak hastalığı ve/veya iskemik kalp hastalığı ile birlikte görülebilir.
