Nilgün I??ksalan Özbülbül

ABSTRACT A knowledge of normal habitus as well as the most frequent variants and abnormalities of the gate venous system are of great importance for liver mathematical process and interventional procedures. An understanding of the varied MDCT appearances of these abnormalities will allow more unambiguous diagnoses and help avoid false diagnoses. Key words: portal vein, abnormalities portal vein, thrombosis portal vein, gas shunts, arterioportal tomography, X-ray computed

he portal venous system is associated with a wide range of indispensable abnormalities and acquired processes that can be detected incidentally with current resourcefulness modalities. In this pictorial essay, we discuss and illustrate the normal anatomy as well as the congenital and acquired abnormalities of the portal venous system as shown by multidetector computed tomography (MDCT). Recognizing the varied features of these abnormalities of the portal venous system will help radiologists to correctly be images and prevent misdiagnoses.



Normal anatomy The portal vein issues from the get together of the superior mesenteric, inferior mesenteric, and splenic veins posterior to the neck of the pancreas. In its most common branching pattern, the portal vein divides at the porta hepatis into the ripe(p) and left portal veins. As it courses cranially, the right portal vein first sends branches to the caudate lobe and then divides into front tooth and posterior branches. The left portal vein first follows a horizontal course to the left and then turns medially toward the ligamentum teres (umbilical portion), supplying the lateral and medial segments of the left lobe (Fig. 1). The Cantlie line corresponds to the median(a) fissure and is defined as a line transient through...If you want to get a full essay, order it on our website: Orderessay
