Core Tip

Core tip: The present review describes the etiopathogenesis and role of imaging modalities in Extra-hepatic portal vein obstruction and role of various radiological interventional procedures in its management. The advantages and potential limitations of each imaging modality namely endoscopic retrograde cholangiography, ultrasonography and Doppler, multidetector computed tomography, magnetic resonance cholangiography and portovenography, endoscopic ultrasound and ultrasound transient elastography are discussed. Also, the concepts behind the use of interventional procedures like transjugular intra-hepatic portosystemic shunt, percutaneous transhepatic biliary drainage, partial splenic embolization, splenic artery aneurysmal embolization, balloon occluded retrograde obliteration of portosystemic shunt, etc., are described.
