ÇOK KESİTLİ BİLGİSAYARLI TOMOGRAFİ İLE PORTAL VEN ANATOMİK VARYASYONLARININ DEĞERLENDİRİLMESİ

Öz

Amaç: Bu çalışmada amaç; rutin üst abdominal çok kesitli bilgisayarlı tomografi (ÇKBT) görüntülerinde portal ven (PV) varyasyon dağılımını ve sıklığını belirlemektir.

Gereç ve Yöntem: Rutin abdominal tomografileri 64 kesit ÇKBT ile çekilen 363’ükadın,387’sierkektoplam 750hastanın görüntüleri retrospektif olarak değerlendirildi.Portal fazda elde edilen görüntüler multiplanar reformat ve üç boyutlu postprosesing sonrası değerlendirildi.

Bulgular: Toplam 750 hastanın 134’ünde (%17.9) ana PV varyasyonları saptandı. Sekiz hastada (% 1.2) sağ posterior portal ven varyasyonu tespit edildi. Tip 1 varyasyon 616 hastada (% 82.1), tip 2 varyasyon 72 hastada (%9.6),tip 3 varyasyon 53 hastada (% 7.4),sağ portal ven trifurkasyonu 8 hastada (%0.9), quadrifikasyon 1 hastada (%0.1),total ramifikasyon 1 hastada (% 0.1) bulundu. Toplamda PV varyason ve anomalisi 142 hastada (%19.1) tespit edildi.

Sonuç: Portal ven varyasyon varlığının saptanmasında ÇKBT etkin bir yöntemdir. Abdominal tomografi incelemelerinin raporlanması sırasında portal ven varyasyonlarına dikkat edilmesi ve belirtilmesi klinik açıdan önemli varyasyonların cerrahi planı değiştirebilmesi ve komplikasyonları azaltması açısından önemlidir.
