Abstract

The aim of this study is to
investigate the diagnostic significance of Computerized Tomography (CT)
angiography in the evaluation of coronary and pulmonary artery anomalies and
accompanying extracardiac structures in pediatric patients with tetralogy of
Fallot. We also aimed to evaluate the surgical benefits of CT angiography
performed before operation. The data of patients with operated tetralogy of
Fallot and variants were retrospectively reviewed between January 2016- January
2018. Patients without CT angiography examination and cases with missing data
were not included in the study. The age, gender, age at diagnosis, echocardiography
and CT angiography and operation procedure were evaluated. A total of 32
patients were included in the study. The mean age of the patients was 18±17
(1-84) months. Of the patients, 6 had Tetralogy of Fallot with pulmonary
atresia and 1 had tetralogy of Fallot without pulmonary valve. The extracardiac
malformations detected by CT anjiography were aortopulmonary collateral artery
in 6 patients, retroaortic innominate ven in 2 patients, aberrant right
subclavian artery in 1 patient and coronary artery anomaly in 1 patient. CT
angiography is important in patients with tetralogy of Fallot showing
concomitant pulmonary artery confluence, diameter and aortopulmonary collateral
artery. This examination provides significant benefits in terms of surgical
choice and approach.

Fallot Tetralojili olguların Preoperatif Değerlendirilmesinde BT Anjiyografinin önemi; Tek merkez deneyimi

Abstract

Çalışmamızda Fallot tetralojili olgularda koroner ve pulmoner arter
anomalileri ve eşlik eden ekstrakardiyak malformasyonların değerlendirilmesinde
Bilgisayarlı Tomografi (BT) anjiyografinin tanısal önemi araştırıldı. Ayrıca
operasyon öncesi çekilen BT anjiyografinin cerrahi açıdan faydalarını
değerlendirmeyi amaçladık. Ocak 2016- Ocak 2018 tarihleri arasında Fallot
tetralojisi (pulmoner kapak yokluklu ve pulmoner atrezili dahil) tanısı konulan
olguların dosyaları geriye dönük olarak incelendi. Bilgisayarlı Tomografi
anjiyografi çekilmemiş olanlar ve dosyasında eksik veri bulunanlar çalışmaya
dahil edilmedi. Hastaların yaşı, cinsiyeti, operasyon yaşı, ekokardiyografi, BT
anjiyografi ve operasyon sonuçları değerlendirildi. Toplam 32 hasta çalışmaya
alındı. Ortalama yaşları 18±17 (1-84) ay idi. 32 hastanın 6’sında pulmoner
kapak atrezili ve 1 olguda pulmoner kapak yokluklu Fallot tetralojisi vardı. BT
anjiyografi ile saptadığımız ekstrakardiyak malformasyonlar 6 olguda
aortopulmoner kolleteral arter, 2 olguda retroaortik seyirli inominate ven,1
olguda aberran sağ subklavian arter ve 1olguda koroner arter anomalisi idi. Fallot
tetralojili hastalarda pulmoner arterlerin konfluensi, çapları ve aortopulmoner
kolleteral arter gibi vasküler yapıları göstermede BT anjiyografi önemlidir. Bu
inceleme cerrahi seçimi ve yaklaşım açısından belirgin fayda sağlamaktadır.
