Sol ventrikül çıkım darlığı bulunan büyük arter transpozisyonunda arteriyel switch operasyonu: 3 Olgu sunumu

Büyük arter transpozisyonu (TGA) ile birlikte sol ventrikül çıkım yolu (SVÇY) veya pulmoner kapak anomalileri bulunan hastalarda arteriyel switch operasyonu (ASO) tartışmalıdır. Bu çalışmada 1998 - 2001 yılları arasında TGA + SVÇY obstrüksiyonu tanısıyla arteriyel switch operasyonu uygulanan 3 hasta değerlendirildi. Bu hastalarda fibromuskuler dokular, anormal kas bandları veya subvalvüler fibröz membran nedeniyle sol ventrikül çıkım yolunda anatomik darlık meydana gelmişti. Ek anomali olarak hastalarda ventriküler septal defekt ve/veya biküspid pulmoner kapak bulunmaktaydı. Tüm hastalarda sol ventrikül çıkım yolu serbestlenerek arteriyel switch operasyonu başarı ile uygulandı.

The arterial switch operation in transposition of the great arteries with left ventricular outflow tract obstruction: 3 case reports

Arterial switch operation is controversial in transpositions of great arteries (TGA) with left ventricular outflow tract (LVOT) or pulmonary valve abnormalities. In this study, we reported 3 consecutive patients with TGA and LVOT abnormalities who underwent an arterial switch operation between 1998 and 2001. In these patients, anatomic LVOT obstruction was developed due to fibromuscular tissues, anomalous muscle bands and subvalvar fibrous membranes. Additional abnormalities were ventricular septal defekt and/or bicuspid pulmonary valve. In all patients arterial switch operation was performed successfully with relief of LVOT obstruction.
