Ultrasound Video showing a mass in porta hepatis.

This video shows a mass in porta hepatis. Ultrasonography is the most commonly used, inexpensive, readily available modality for evaluation of the porta hepatis. The availability of high-resolution transducers has increased its importance for daily practice. Color, spectral, and power Doppler US provide excellent information about the vascular structures in the porta hepatis. Porta hepatis is a transverse fissure on the visceral surface of the liver between the caudate and quadrate lobes. It lodges the followings structures also called portal triad. From anterior to posterior i.e. common hepatic duct ( It leaves) hepatic artery proper (It enters). hepatic portal vein (It enters). The normal portal vein has a diameter of 11–13 mm The hepatic duct lies in front and to the right, the hepatic artery to the left, and the portal vein behind and between the duct and artery It also transmits nerves and lymphatics. Sympathetic nerves and Hepatic branch of the vagus nerve Thrombosis of the portal vein is seen with various pathologic conditions. Common causes include cirrhosis; cholangitis; pancreatitis; appendicitis; diverticulitis; neoplasms such as hepatocellular carcinoma and pancreatic cancer; hypercoagulable states; and surgeries such as liver transplantation, splenectomy, and portosystemic shunt surgery. Imaging plays a crucial role in accurate diagnosis of a broad spectrum of pathologic conditions of the porta hepatis. Thanks for watching. Please subscribe my channel.
