Pseudoaccessory fissures are common anatomic variants that result from invaginations of diaphragmatic muscle fibers, usually along the superior surface of the liver (Fig. 85-2). They are more frequently seen involving the right hepatic lobe, but they can occur on the left as well.

Living donor liver transplantation (LDLT) is a technically demanding endeavor, requiring command of the complex anatomy of partial liver grafts. We examined the influence of anatomic variation and reconstruction techniques on surgical outcomes and graft survival in the 9-center Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL).

Because MR cholangiography is be-coming the modality of choice for noninvasive evaluation of abnormalities of the biliary tract and because surgical procedures such as liver re-sections and partial liver transplantations are in- Peritoneum may be embedded on this waist and may mimic a hematoma, infarction, or laceration. Deep fissures tend to occur along the superior border of the spleen. When they occur along the inferior border, a lobule of splenic tissue may extend medially and anteriorly to the left kidney. anatomical variant of liver, spleen was 15 cm in size and portal vein was 17mm in caliber. So we made the diagnosis of Hemangioma left lobe of liver with Hepatic Papillary process and Hepatosplenomegaly. A significant number of normal anatomical and Hepatic Vascular variants occur and knowledge of the common variants is essential for diagnosis. 2015-04-17 · The other two most common variants are a replaced right hepatic artery, in which the CA supplies the left hepatic artery and the SMA supplies the right hepatic artery (10.6%), and a quadrifurcating CA, with separate origins of the right and left hepatic arteries directly from the CA (9.7%).

An anatomical variation, anatomical variant, or anatomical variability is a difference between the anatomical structures of animals from the same species.The variations are seen as normal in the sense that they are found consistently among different individuals, are mostly without symptoms, and are termed anatomical variations rather than abnormalities. Request PDF | Anomalies and Anatomic Variants of the Liver | Knowledge of the anomalies and anatomical variants of the liver is often of great importance because these may be misinterpreted as The anatomically distinct segment I, or caudate lobe, lies between the fissure for the ligamentum venosum and the vena cava inferior.

The knowledge of anatomical liver vascular variants is crucial for decreasing operative and postoperative morbidity and mortality during the performance of hepatic and pancreatic surgeries (7) (8)(9). Request PDF | Anomalies and Anatomic Variants of the Liver | Knowledge of the anomalies and anatomical variants of the liver is often of great importance because these may be misinterpreted as Anatomical variants of the classical pattern were detected in 30% of the livers (n = 320). The most common variant was a replaced left artery arising from the left gastric artery (9.7%) followed by a replaced right hepatic artery arising from the superior mesenteric artery (7.8%). Anatomical variants of the classical pattern were detected in 30% of the livers (n=320). The most common variant was a replaced left artery arising from the left gastric artery (9.7%) followed by a replaced right hepatic artery arising from the superior mesenteric artery (7.8%). This is a fibrous band which attaches to the diaphragm at the left extremity of the liver and may contain liver parenchyma. 2 This is an important structure intraoperatively as it may contain blood vessels and bile ducts and should be ligated with care.
