Sinistral portal hypertension associated with pancreatic pseudocysts - ultrasonography findings: A case report

Abstract Background: Sinistral portal hypertension results from obstruction or stenosis of the splenic vein and is characterized by normal portal vein pressures and liver function tests. Gastrointestinal bleeding is the most common presentation and indication for treatment. Although sinistral portal hypertension-related chylous ascites is rare, several cases have described successful treatment with portal venous, rather than splenic venous, recanalization. Splenectomy is effective in the treatment of sinistral portal hypertension-related bleeding, although recent studies have evaluated splenic vein stenting and splenic arterial embolization as minimally-invasive treatment alternatives. Splenic vein stenting may be a viable option for other presentations of sinistral portal hypertension. Case Presentation: A 59-year-old gentleman with a history of necrotizing gallstone pancreatitis was referred to interventional radiology for management of recurrent chylous ascites. Analysis of ascites demonstrated a triglyceride level of 1,294 mg/dL. Computed tomography revealed splenic and superior mesenteric venous stricture. The patient elected to undergo minimally invasive transhepatic portal venography, which confirmed the presence of splenic vein and superior mesenteric vein stenosis. Venography of the splenic vein showed reversal of portal venous flow, multiple collaterals, and a pressure gradient of 14 mmHg. Two 10 mm x 40 mm Cordis stents were placed, which decreased the pressure gradient to 7 mmHg, and resolved the portosystemic collaterals. At 6 months follow-up, the patient had no recurrent episodes of ascites. Conclusion: The current case highlights successful treatment of sinistral portal hypertension-related intractable chylous ascites treated with transhepatic splenic vein stenting. Splenic venous stent patency rates of 92.9% at twelve months have been reported. Rebleeding rates of 7.1% for splenic vein stenting, 16% for splenectomy, and 47.8% for splenic arterial embolization have been reported in the treatment of sinistral portal hypertension-related gastrointestinal bleeding. The literature regarding splenic vein stenting for sinistral portal hypertension-related ascites is less robust. Technical and clinical success in the current case suggests that splenic vein recanalization may be a safe and viable option in other sinistral portal hypertension-related symptomatology.Level of Evidence: Level 4, Case Report

Introduction: The umbilical vein can become recanalised due to portal hypertension in patients with liver cirrhosis but the condition is rarely clinically significant. Although bleeding from this enlarged vein is a known complication, the finding of thrombophlebitis has not been previously described. Case report: We report the case of a 62-year-old male with a history of liver cirrhosis due to alcoholic liver disease presenting to hospital with epigastric pain. A CT scan of the patient’s abdomen revealed a thrombus with surrounding inflammatory changes in a recanalised umbilical vein. The patient was managed conservatively and was discharged home the following day. Conclusion: Thrombophlebitis of a recanalised umbilical vein is a rare cause of abdominal pain in patients with liver cirrhosis.

Sinistral Portal Hypertension

Abstract Objectives Sinistral portal hypertension (SPH) is caused by increased pressure on the left portal system secondary to splenic vein stenosis or occlusion and may lead to gastric varices. The definitive management of SPH is splenectomy, but this is associated with significant mortality and morbidity in the acute setting. In this systematic review, we investigated the efficacy and safety of splenic artery embolisation (SAE) in managing refractory variceal bleeding in patients with SPH. Methods A comprehensive literature search was conducted using MEDLINE and Embase databases. A qualitative analysis was chosen due to heterogeneity of the studies. Results Our search yielded 339 articles, 278 of which were unique. After initial screening, 16 articles relevant to our search remained for full text review. Of these, 7 were included in the systematic review. All 7 papers were observational, 6 were retrospective. Between them they described 29 SAE procedures to control variceal bleeding. The technical success rate was 100% and there were no cases of rebleeding during follow up. The most common complication was post-embolisation syndrome. Four major complications occurred, two resulting in death. These deaths were the only 30-day mortalities recorded and were in patients with extensive comorbidities. Conclusions Although there is a distinct lack of randomized controlled studies comparing SAE to other treatment modalities, it appears to be safe and effective in treating hemorrhage secondary to SPH.
