Prevalence and Types of Main and Right Portal Vein Branching Variations on MDCT

Abstract: Variant main portal vein branching seems to be very frequent. Common right anterior portal vein-left portal vein trunk is far more common than trifurcation. Although less frequent, variations also occur in right portal vein branching.

“…Anatomical variations in the branching of the PV are relatively common [2,6]. The most remarkable observation of the current study is the low preva-lence (51%) of Type 1 mode of termination compared to prevailing reports in literature (Table 1).…”

“…The branching pattern of the PV was classified after Atasoy and Ozvurek [2], as follows: Type 1 -conventional bifurcation; Type 2 -variant bifurcation in which the PV gave the right anterior PV and a common trunk from which arose the left PV and right posterior PV; Type 3 -trifurcation if it gave three branches -the right anterior, right posterior and the left portal veins. In addition, we included what we called type 4, that is: quadrifurcation if it gave, besides the branches observed in Type 3, a branch to the caudate lobe whose diameter was at least a third of that of the PV.…”

“…Tariflenen bu anatomik yapı tip 1 olarak sınıf-landırılmış olup, geri kalan tüm farklılıklar varyasyon olarak kabul edilir. Multidedektör BT ve rekonstrüksiyon görüntüler ile yapılan ça-lışmalarda, toplumun %65-80 kadarında tip 1 [25,26]. Daha nadir karşılaşılan portal venöz sistem varyasyonları da tanımlanmıştır; ancak bu varyasyonların oranı %2'yi geçmemektedir [25,26].…”
