Multislice computed tomography angiography is a sufficient method for detecting native aortic coarctation in children

Amaç: Düşük dozlu çok kesitli bilgisayarlı tomografik (ÇKBT) anjiyografinin aort koarktasyonu ve lezyonla ilişkili eşzamanlı anomalilerin anatomik yapısının saptanmasında non-invazif bir yöntem olarak uygulanabilirliği ve etkinliği araştırıldı. Çalışma planı: Şubat 2009 - Haziran 2010 tarihleri arasında kliniğimizde renkli Doppler ekokardiyografi (RDE) ve ÇKBT anjiyografi uygulanan toplam 15 çocuk hasta (9 erkek, 6 kız; ort. yaş 34 ay; dağılım 8 gün ila 10 yıl) çalışmaya dahil edildi. On altı kesitli bilgisayarlı tomografide görüntüleme alanı göğüs üst bölümü ile diyafram tepe kısmı olarak seçildi. Bulgular: Aksiyal incelemelerde koarktasyon ile ilgili bulgular iki olguda belirgin değildi (%13.3; n=2). Üç boyutlu görüntülemelerde ise tüm koarktasyon alanları net olarak gösterildi (%100; n=15). Aort koarktasyonunu saptamada ÇKBT’nin toplam duyarlılığı %100 ile RDE’ye göre daha yüksek (%86.6; n=13) idi. Tüm hastaların tanısı cerrahi olarak doğrulandı. Sonuç: Bu çalışmada düşük dozlu ÇKBT anjiyografinin çocuklardaki aort koarktasyonunu saptamada bir non-invazif yöntem olarak uygulanabilirliği ve etkinliği kanıtlandı.

Çok kesitli bilgisayarlı tomografik anjiyografi çocuklarda aort koarktasyonunun saptanmasında yeterli bir yöntemdir

of low dose multislice computed tomography (MSCT) angiography as a noninvasive method in detecting anatomic structures of lesion and combined anomalies associated with coarctation of the aorta. Methods: A total of 15 pediatric patients (9 boys, 6 girls; mean age 34 months; range 8 days to 10 years) who underwent color Doppler echocardiography (CDE) and MSCT angiography for coarctation in our clinic between February 2009 and June 2010 were included in this study. The thorax was scanned from the cupula to the top of the diaphragm by using 16-slice computed tomography. Results: Upon axial imaging, anatomical findings related with coarctation were not apparent in two patients (86.6%; n=2). The three-dimensional images clearly showed all of the areas of coarctation (100%; n=15). The overall sensitivity of MSCT diagnosis for coarctation was 100%, which was higher than CDE (86.6%; n=13). The diagnosis for each patient was confirmed with surgery. Conclusion: The study proved the feasibility and efficiency of low-dose MSCT angiography as a noninvasive method to detect the native aortic coarctation in children.
