Portal hypertension is most commonly caused by increased intrahepatic resistance as a result of cirrhosis, but can also occur as a result of abnormally high portal bloodflow. This article describes a patient with a history of remote liver trauma in whom portal hypertension and variceal bleeding were shown to be due to an arteriovenous fistula between the hepatic artery and portal vein. Transcatheter embolization with Gianturco coils resulted in obliteration of the fistula and normalization of portal pressures.

BACKGROUND: Presinusoidal portal hypertension with frequent episodes of upper gastrointestinal variceal bleeding are hallmarks of hepatosplenic Manson’s schistosomiasis; a clinical form that affects about 5% of Brazilians who are infected by Schistosoma mansoni. AIMS: To evaluate duplex sonography findings in patients with hepatosplenic Manson’s schistosomiasis with and without upper gastrointestinal variceal hemorrhage. METHODS: A cross-sectional study was performed whereby 27 consecutive patients with hepatosplenic Manson’s schistosomiasis were divided into two groups: group I (six men and six women; mean age 48.7 years) with a past history of bleeding and group II (four men and eight women; mean age 44.7 years) without a past history of upper gastrointestinal bleeding, underwent duplex sonography examination. All patients underwent the same upper gastrointestinal endoscopy and laboratory examinations. Those with signs of mixed chronic liver disease or portal vein thrombosis (three cases) were excluded. RESULTS: Group I showed significantly higher mean portal vein flow velocity than group II (26.36 cm/s vs 17.15 cm/sec). Although, as a whole it was not significant in all forms of collateral vessels (83% vs 100%), there was a significantly higher frequency of splenorenal collateral circulation type in group II compared with group I (17% vs 67%). The congestion index of the portal vein was significantly lower in group I than in group II (0.057 cm vs 0.073 cm/sec). CONCLUSION: Our duplex sonography findings in hepatosplenic Manson’s schistosomiasis support the idea that schistosomotic portal hypertension is strongly influenced by overflow status, and that collateral circulation seems to play an important role in hemodynamic behavior.

Abstract Background Our purpose is to compare the stent patency and clinical outcome of trans-jugular intra-hepatic porto-systemic shunt (TIPS) through the left branch portal vein (TIPS-LPV) to the standard TIPS through the right branch (TIPS-RPV). We retrospectively reviewed all patients (n = 54) with refractory portal hypertension who were subjected to TIPS-LPV at our institute (TIPS-LPV) between 2016 and 2018. These patients were matched with 56 control patients treated with the standard TIPS-RPV (TIPS-RPV). The 2 groups were compared regarding the stent patency rate, encephalopathy, and re-interventions for 1 year after the procedure. Results TIPS-LPV group showed 12 months higher patency rate (90.7% compared to 73.2%) (P < 0.005). The number of the encephalopathy attacks in the TIPS-LPV group was significantly lower than that of the TIPS-RPV group at 6 and 12 months of follow-up [P = 0.012 and 0.036, respectively]. Re-bleeding and improvement of ascites were the same in the two groups [P > 0.05]. Patients underwent TIPS-LPV needed less re-interventions and required less hospitalizations than those with TIPS-RPV [P = 0.039 and P = 0.03, respectively]. Conclusion The new TIPS approach is to extend the stent to LPV. This new TIPS-LPV approach showed the same clinical efficiency as the standard TIPS-RPV in treating variceal bleeding and ascites. However, it proved a better stent patency with lower rates of re-interventions, encephalopathy, and hospital admissions than TIPS through the right branch.

Abstract Background When a postoperative hepatic artery pseudoaneurysm develops after massive hepatectomy, both an intervention for the pseudoaneurysm and patency of hepatic artery should be considered because occlusion of the residual hepatic artery results in critical liver failure. However, the treatment strategy for a pseudoaneurysm of the hepatic artery after hepatobiliary resection is not well established. Case presentation A 65-year-old woman underwent right hepatectomy, extrahepatic duct resection, and portal vein resection, for gallbladder cancer. Although the patient had an uneventful postoperative course, computed tomography on postoperative day 6 showed a 6-mm pseudoaneurysm of the hepatic artery. Angiography revealed the pseudoaneurysm located on the bifurcation of the left hepatic artery to the segment 2 artery plus the segment 3 artery and 4 artery. Stent placement in the left hepatic artery was not feasible because the artery was too narrow, and coiling of the pseudoaneurysm was associated with a risk of occluding the left hepatic artery and inducing critical liver failure. Therefore, portal vein arterialization constructed by anastomosing the ileocecal artery and vein was performed prior to embolization of the pseudoaneurysm to maintain the oxygen level of the remnant liver, even if the left hepatic artery was accidentally occluded. The pseudoaneurysm was selectively embolized without occlusion of the left hepatic artery, and the postoperative laboratory data were within normal limits. Although uncontrollable ascites due to portal hypertension occurred, embolization of the ileocolic shunt rapidly resolved it. The patient was discharged on postoperative day 45. Conclusion Portal vein arterialization prior to embolization of the aneurysm may be a feasible therapeutic strategy for a pseudoaneurysm that develops after hepatectomy for hepatobiliary malignancy to guarantee arterial inflow to the remnant liver. Early embolization of arterioportal shunting after confirmation of arterial inflow to the liver should be performed to prevent morbidity induced by portal hypertension.

Abstract Purpose of the Review Non-cirrhotic portal hypertension (NCPH) includes a heterogeneous group of conditions. The aim of this paper is to make an overview on the denominations, diagnostical features and management of porto-sinusoidal vascular disease (PSVD) and chronic portal vein thrombosis (PVT) being the main causes of NCPH in the Western world. Recent Findings The management of NCPH consists in the treatment of associated diseases and of portal hypertension (PH). PH due to PSVD or PVT is managed similarly to PH due to cirrhosis. TIPS placement and liver transplantation are considerable options in patients with refractory variceal bleeding/ascites and with progressive liver failure. Anticoagulation is a cornerstone both in the treatment of thrombosis in PSVD and in the prevention of thrombosis recurrence in patients with portal cavernoma. Summary Physicians should be aware of the existence of PSVD and chronic PVT and actively search them in particular settings. To now, the management of portal hypertension-related complications in NCPH is the same of those of cirrhosis. Large cooperative studies on the natural history of NCPH are necessary to better define its management.

Aim. To compare the effectiveness of surgical procedures (selective or nonselective shunt, devascularization, and combined shunt and devascularization) in preventing recurrent variceal bleeding and other complications in patients with portal hypertension. Methods. A systematic literature search of the Medline and Cochrane Library databases was carried out, and a meta-analysis was conducted according to the guidelines of the Quality of Reporting Meta-Analyses (QUOROM) statement. Results. There were a significantly higher reduction in rebleeding, yet a significantly more common encephalopathy () in patients who underwent the shunt procedure compared with patients who had only a devascularization procedure. Further, there were no significant differences in rebleeding, late mortality, and encephalopathy between selective versus non-selective shunt. Next, the decrease of portal vein pressure, portal vein diameter, and free portal pressure in patients who underwent combined treatment with shunt and devascularization was more pronounced compared with patients who were treated with devascularization alone (). Conclusions. This meta-analysis shows clinical advantages of combined shunt and devascularization over devascularization in the prevention of recurrent variceal bleeding and other complications in patients with portal hypertension.

Introduction. Arteriovenous fistula of the superior mesenteric blood vessels is a rare complicaton in abdominal surgery. Case report. We presented a 49-year-old man with cramplike abdominal pain, abdominal distension and weight loss symptoms, with a history of previous small bowel resection and right colectomy, due to Crohn disease, 16 years ago. Clinical examination revealed a paraumbilical pulsation with systolic murmur and thrill. Ultrasonography and computed tomography revealed cystic dilatation of the superior mesenteric vein, hepatomegaly and ascites. Upper endoscopy revealed grade I esophageal varices with portal hypertensive gastropathy. The diagnosis of arteriovenous fistula between superior mesenteric artery and vein was confirmed by angiogram of the superior mesenteric vessels and resection of the fistula was performed. Control examination after nine months showed no signs of portal hypertension. Conclusion. Early diagnosis and treatment of mesenteric blood vessel arteriovenous fistula prevents portal hypertension development and its complications.

A patient is presented with multiple vascular anomalies in the branches of the celiac axis as well as in the portal vein and its branches. Apparently, unique in the literature is the presence of a large arteriovenous fistula between the hepatic artery and one of the hepatic veins. The anomalies are presumed to be congenital in origin.
