Abstract Background Isolated splenic vein thrombosis (iSVT) is a common complication of pancreatic disease. Whilst patients remain asymptomatic, there is a risk of sinistral portal hypertension and subsequent bleeding from gastric varices if recanalization does not occur. There is a wide variation of iSVT treatment, even within single centres. We report outcomes of iSVT from tertiary referral hepatobiliary and pancreatic (HPB) units including the impact of anticoagulation on recanalization rates and subsequent variceal bleeding risk.   Methods A retrospective cohort study including all patients diagnosed with iSVT on CT scan abdomen and pelvis between 2011 and 2019 from two institutions. Patients with both SVT and portal vein thrombosis at diagnosis, and isolated splenic vein thrombosis secondary to malignancy were excluded. The outcomes of anticoagulation, recanalization rates, risk of bleeding, and progression to portal vein thrombosis were examined. Results Ninety-eight patients with iSVT were included; of which thirty-nine patients received anticoagulation (40%). The most common cause of iSVT was acute pancreatitis n = 88 (90%). The recanalization rate in the anticoagulation group was 46% vs 15% in patients receiving no anticoagulation (p = 0.0008, OR = 4.7, 95% CI 1.775 to 11.72). Upper abdominal vascular collaterals (demonstrated on CT scan angiography) were significantly less among patients who received anticoagulation treatment (p = 0.03, OR = 0.4, 95% CI 0.1736 to 0.9288). The overall rate of upper GI variceal related bleeding was 3% (n = 3/98) and it was independent of anticoagulation treatment. Two of the patients received therapeutic anticoagulation. Conclusions The current data support that therapeutic anticoagulation is associated with a statistically significant increase in recanalization rates of the splenic vein; with a subsequent reduction in radiological left-sided portal hypertension. However, all patients had a very low risk of variceal bleeding regardless of anticoagulation. The findings from this retrospective study should merit further investigation in large-scale randomized clinical trials.

Abstract Results A 41-year old Asian male, who immigrated to Canada many years ago, and who had previously been successfully treated for Helicobacter pylori infection underwent gastroscopy for investigation of dyspepsia. His gastroscopy was normal except for a large subepithelial abnormality that was noted close to the gastroesophageal junction. Routine gastric biopsies from the antrum and body were normal. Subsequent endoscopic ultrasound revealed flow through the anechoic tortuous lesion and confirmed it was a very large isolated gastric varix type 1. Abdominal CT scan revealed chronic occlusion of the portal vein, splenic vein, and the portal confluence with extensive collateralization in the upper abdomen. There was complete cavernous transformation of the portal vein. Of the numerous varices in the upper abdomen, a very large varix drained into the left renal vein and indented into the posterior wall of the fundus of the stomach which accounted for the endoscopic finding. Multiple mesenteric veins were identified that connected to varices adjacent to the inferior aspect of the pancreas and duodenum. Notably, there was no evidence of cirrhosis or chronic pancreatitis. Liver enzymes, albumin, and INR were normal. Further collateral history revealed that he was hospitalized as a neonate for pneumonia with catheterization of the umbilical vein, which is known to be associated with thrombosis of the portal vein. Conclusions Detection of congenital absence of the portal vein (CAPV) is recognized more often due to advances in diagnostic imaging. Radiologically, the absence of the portal vein in CAPV is distinguished from portal vein thrombosis by the lack of venous collaterals or sequalae of portal hypertension, such as ascites or splenomegaly. A more gradual thrombosis of the portal vein may permit collaterals to develop without acute changes and is not equivalent to portal vein aplasia or agenesis as intrahepatic bile ducts are normal. The gold standard for diagnosis of CAPV is histologic absence of the portal vein in the liver on catheter angiography. CAPV is associated with abnormal embryologic development of the portal vein and frequently presents with complications of portal hypertension or portosystemic encephalopathy or the sequalae of venous shunts, hepatic or cardiac abnormalities found on imaging. Our case is an incidentally discovered absence of the portal venous system due to chronic thrombosis with extensive collateralization and an enlarged gastric varix protruding into the proximal stomach. It is well documented that canalization of the umbilical vein in infancy is associated with portal vein thrombosis, with incidences up to 68%. This case highlights the importance of eliciting a childhood hospitalization history in cases of non-cirrhotic portal hypertension. Funding Agencies None

Abstract Background One of the complications of portal hypertension, with or without the presence of cirrhosis, is the development of varices along the length of the gastrointestinal tract. The commonest sites are along the esophagus or in the stomach. Ectopic varices in the small and large bowels can also be observed, but ectopic varices in the pharynx are extremely uncommon. Aims To present a case series and review the literature regarding pharyngeal varcies. Methods - Results Three elderly female patients presented for esophagogastric varices surveillance gastroscopy were diagnosed with pharyngeal varices. One patient has hepatitis C cirrhosis, while the other two non-cirrhotic patients have myeloproliferative neoplasm (MPN). None of the patients had thromboses of the portal vein or its tributaries. All three patient have concomitant esophageal varices, but only one required band ligation of her esophageal varices. All patients are asymptotic except for mild dysphagia. No patient has bled from their pharyngeal varices to date. Two patients have had prophylactic treatment of their portal hypertension with non-selective beta blocker (NSBB), while the third one has not received NSBB prophylaxis because of her age. Conclusions Pharyngeal varices are extremely rare. To date, there are three case reports in the literature, however, we have been able to identify three cases in our practice. The previous two cases reported possible left-sided portal hypertension with splenic vein thrombosis, leading to the development of collateral vessels including a gastrocaval shunt, which by some contiguous route connects to the brachiocephalic vein; and a third case was a complication of neck dissection surgery. In our case series, none of our patients had splenic vein thrombosis. However, none of them has had a careful CT angiogram to delineate the portal vein tributaries and the collateral vessels, which may further help to define their pathogenesis. It is unclear whether NSBB would be effective as primary prophylaxis against their bleeding, The plan is to continue to monitor these patients to learn about the natural history of these pharyngeal varices.

Variceal bleeding remains a fatal complication of portal hypertension. Periampullary varices are rare and, due to their location, are difficult to diagnose and treat. Similar to esophagogastric varices, they are the result of high portosystemic pressures secondary to intrahepatic causes such as cirrhosis and extrahepatic causes such as portal or splenic vein thrombosis. We report a case of a periampullary varix resulting in hemobilia during endoscopic retrograde cholangiopancreatography (ERCP).

Portal cavernoma is the cavernous transformation of the portal vein. It is the consequence of chronic portal vein thrombosis and occurs when collateral branches develop to bypass the portal occlusion. The clinical presentation includes hematemesis due to variceal bleeding, ascites or anemia, and splenomegaly. Herein we present images of a 37-year-old male patient received in our department for abdominal ultrasound, following 2 episodes of hematemesis. This case illustrates the ultrasound aspect of a voluminous portal cavernoma with portal hypertension signs.

Two infants with portal hypertension were treated on an emergency basis for life-threatening uncontrollable variceal bleeding. One 9-month-old girl had portal vein thrombosis, and the other 28-months-old girl had liver cirrhosis secondary to biliary atresia. Following percutaneous transhepatic embolization of the varices, successful bleeding control was achieved in both patients.
