In this study we have examined blood flow in a model of the portal vein with and without obstructions to simulate conditions, which are common in liver diseases. We evaluated the impact of both conditions on the flow behaviour and found significant differences in the two models. Blockages, even when the flow conditions did not change, had an impact on the velocity magnitude, pressure, strain ra...

BACKGROUND Hepatobiliary cancer invading the hilar bile duct often involves the portal bifurcation. Portal vein resection and reconstruction is usually performed after completion of the hepatectomy. This retrospective study assessed the safety and usefulness of portal vein reconstruction prior to hepatic dissection in right hepatectomy and caudate lobectomy plus biliary reconstruction, one of t...

This study was conducted to correlate the portal vein diameter measured by ultrasound to development of oesophageal varices in patients with cirrhosis of liver with portal hypertension. 92 patients with cirrhosis admitted in OGH were selected for the study USG was conducted in all patients to note portal vein size and splenic size. Upper GI endoscopy was done to detect presence of varices with ...

Portal biliopathy (PB) is a rare disorder, which mostly presents as sub-clinically. It occurs most commonly due to idiopathic extrahepatic portal vein obstruction. We present three cases having features of portal biliopathy secondary to portal hypertension. Our first case did not have a prior history of chronic liver disease while next two patients had previous history of chronic liver disease ...

OBJECTIVES Sinusoidal injury (SI) after oxaliplatin-based therapies for colorectal liver metastasis (CRLM) can increase postoperative morbidity. Preoperative methods to estimate SI are lacking. The aim of this study was to identify SI by evaluating portal vein haemodynamics. METHODS Magnetic resonance imaging flowmetry (MRIF) was used to estimate portal vein haemodynamics in 29 patients with ...

Results The portal and superior mesenteric vein injuries developed at the time of tumor excision by general surgeons. We joined the operation of general surgeons. Proximal and distal region of the portal and superior mesenteric vein were compressed with hand to stop bleeding. The portal and superior mesenteric veins were repaired with 6/0 prolene suture. The portal and superior mesenteric vein ...

BACKGROUND Laparoscopic splenectomy has become an important therapeutic option in the management of diverse hematologic disorders. However, the incidence of important complications, such as portal vein thrombosis, remains poorly understood. We set out to study the incidence of this complication over a 14-month period. METHODS All adult patients who underwent laparoscopic splenectomy between J...

We report herein the case of a patient successfully treated by transhepatic portal venous stent placement for malignant portal vein obstruction with associated gastric and small bowel varices and repeated gastrointestinal bleeding. CT angiography and portography showed severe portal vein obstruction from recurrent pancreatic cancer 15 months following pancreaticoduodenectomy with tumor encaseme...

lar complications including thromboses of the portal venous system and the formation of a pseudoaneurysm. Pseudoaneurysms occur in approximately 3.5-10.0% of patients with pancreatitis (1). The arteries most commonly affected by pseudoaneurysms are (in decreasing percent occurrence), the splenic (40%), gastroduodenal (30%), pancreaticoduodenal (20%), gastric (5%), hepatic (2%), and others (supe...

Portal vein thrombosis may occur in the presence or absence of underlying liver disease, and a combination of local and systemic factors are increasingly recognized to be important in its development. Acute and chronic portal vein thrombosis have traditionally been considered separately, although a clear clinical distinction may be difficult. Gastrooesophageal varices are an important complicat...
