Sinistral Portal Hypertension

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 1294 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 × 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 the 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 12 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.

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.

Abstract Background Common etiologies of upper gastrointestinal bleeding (UGIB) in cirrhotic patients with portal hypertension include gastroesophageal varices (GOV), portal hypertensive gastropathy (PHG) and gastric antral vascular ectasia (GAVE). Less commonly, patients with portal hypertension develop varices in ectopic sites, including the rectum, biliary tree and duodenum. Ectopic varices are rare, contributing to 1–5% of all variceal bleeding, of which 17% is from duodenal varices. Aims To describe the management of duodenal variceal hemorrhage. Methods A case report and literature review was performed. Results Case report: We present a case of recurrent UGIB in a 59-year-old male with decompensated cirrhosis due to non-alcoholic steatohepatitis (CP-C; Meld 14). Initial endoscopy was negative for GOV, peptic ulcer, PHG, and GAVE, but an erosion over a mucosal bulge in the third segment of the duodenum was identified, raising possibility of vascular malformation versus ectopic varix. There was active bleeding after water provocation, so clips were deployed for hemostasis. CT imaging showed mesenteric venous collaterals abutting the duodenum, again raising possibility of duodenal varix, which was ultimately confirmed by endoscopic ultrasound (EUS). Patient had recurrent overt bleeding despite beta-blockage for prophylaxis, endoscopic clipping on four separate occasions, attempted angioembolization by interventional radiology, and cyanoacrylate glue. Transjugular intrahepatic porto-systemic shunt (TIPS) was not possible due to portal vein occlusion, so he underwent EUS-guided cyanoacrylate glue a second time. Literature review: Ectopic varices are rare, contributing to 1–5% of all variceal bleeding, of which 17% is from duodenal varices. Duodenal variceal hemorrhage can lead to hemorrhagic shock, and is potentially life threatening, with quoted mortality rates of 40%. Unfortunately, duodenal varices can be difficult to identify. Diagnosis is often delayed due to a combination of lower awareness and endoscopic challenges given the unusual serosal and submucosal location. Evidence-based guidelines for the management of ectopic varices are limited. For this reason, our current management strategies rely heavily on local expertise. Splanchnic vasoconstrictor medication, endoscopic ligation, EUS guided gluing, interventional radiology guided embolization, TIPS, balloon retrograde transvenous obliteration and surgical shunts are potential therapeutic options to manage the acutely bleeding varix. Following a variceal bleed, liver transplantation should be considered in eligible patients with no other contraindications. Conclusions Duodenal varices are a rare, potentially fatal, and underrecognized cause of gastrointestinal bleeding in patients with portal hypertension. Definitive therapy currently relies upon local expertise in the absence of clear guideline-based therapy. Funding Agencies None
