An Update: Portal Hypertensive Gastropathy and Colopathy.

Complications of portal hypertension include portal hypertensive gastropathy and colopathy. These disorders may cause chronic or acute gastrointestinal bleeding. The diagnosis is made endoscopically; therefore, there is great variability in their assessment. Portal hypertensive gastropathy can range from a mosaic-like pattern resembling snakeskin mucosa to frankly bleeding petechial lesions. Portal hypertensive colopathy has been less well-described and is variably characterized (erythema, vascular lesions,...


Warfarin prevented de novo portal vein thrombosis after transjugular intrahepatic portosystemic shunt: A retrospective study.

Portal vein thrombosis (PVT) might impair the prognosis of cirrhotic patients. However, formation of de novo PVT after transjugular intrahepatic portosystemic shunt (TIPS) in cirrhotic patients without preexisting PVT was rarely reported. Moreover, it is not known whether warfarin is efficient in preventing de novo PVT after TIPS. The current study aimed to investigate retrospectively the incidence and location of de novo PVT, and preventive effects of warfarin on de novo PVT after TIPS for cirrhotic patien...

The porto-hepatic spectrum of cirrhotic encephalopathy.

It should be considered that portal hypertension per se has the ability of inducing by mechanotransduction an inflammatory response in the mesenteric venous system. This splanchnic endothelial inflammatory response related to the excessive mechanical energy can spread by a paracrine mechanism to an array of cells located in the subendothelial space. Of note, one of the cellular types that are increased in the above-mentioned subendothelial space in portal hypertension is the mast cell. Inflammatory splanchn...

Management of Portal Hypertension and Ascites in Polycystic Liver Disease.

Patients suffering from polycystic liver disease may develop Hepatic Venous Outflow Obstruction, Portal Vein Obstruction and/or Inferior Caval Vein Syndrome due to cystic mass effect. This can cause portal hypertension, leading to ascites, variceal hemorrhage or splenomegaly. For this review, we evaluate the evidence to provide clinical guidance for physicians faced with this complication. Diagnosis is made with imaging such as ultrasound, CT or MRI. Therapy includes conventional therapy with diuretics and ...

Reply.

We read with interest the letter by Dondossola et al. concerning our article "Vascular remodeling of visceral arteries following interruption of the splenic artery during liver transplantation". Authors data seem to confirm our hypothesis that patients suffering from severe portal hypertension are more prone to develop vascular remodeling and also suggest that a dynamic evaluation of vascular remodeling over time could be used as an accessory tool to diagnose persistent portal hypertension after liver tran...

Complications of liver cirrhosis - pharmaceutical versus interventional therapy.

The prognosis of patients with liver cirrhosis is impaired by complications such as variceal bleeding, ascites, hepatorenal syndrome, hepatic encephalopathy and hepatocellular carcinoma. A steadily increasing array of treatment options for these complications is available, including pharmaceutical treatment (e. g. beta blockers for varices or diuretics for ascites), endoscopic treatment (e. g. band ligation of varices), radiological interventions (e. g. transjugular shunt, transarterial chemoembolizat...

Too Much, Too Little, or Just Right? The Importance of Allograft Portal Flow in Deceased Donor Liver Transplantation.

While portal flow (PF) plays an important role in determining graft outcomes in living donor liver transplantation, its impact in deceased donor whole liver transplantation (DDLT) is unclear. The aim of this study was to investigate the correlations between graft PF and graft outcomes in DDLT.

Long-term drug treatments to improve prognosis of patients with liver cirrhosis and to prevent complications due to portal hypertension.

Portal hypertension in patients with liver cirrhosis can be improved, not only by surgical or interventional shunt placements, but also by drug-only treatment. Many recent studies addressed the question whether any of these substances can improve survival of patients with liver cirrhosis when administered continuously for months and years. Non-selective beta-blockers (NSBB), statins, antibiotics, enoxaparin and albumin have been shown to possess many beneficial effects in the pathophysiology of portal hyper...

Anticoagulation in patients with cirrhosis and portal vein thrombosis: safety and beneficial effect on OLT free survival.

We read with interest the letter by Andrea Mancuso on clinical significance of portal vein thrombosis (PVT) in cirrhosis and potential utility of anticoagulation. In our prospective study, thrombocytopenia and previous decompensation of cirrhosis predicted PVT development in cirrhosis suggesting that severity of portal hypertension rather than liver failure plays a pathophysiologic role .

Surgery in Patients with Portal Hypertension.

Patients with portal hypertension will increasingly present for nontransplant surgery because of the increasing incidence of, and improving long-term survival for, chronic liver disease. Such patients have increased perioperative morbidity and mortality caused by the systemic pathophysiology of liver disease. Preoperative assessment should identify modifiable causes of liver injury and distinguish between compensated and decompensated cirrhosis. Risk stratification, which is crucial to preparing patients an...

Partial orthotopic liver transplantation in combination with two-stage hepatectomy: A proof-of-concept explained by mathematical modeling.

Resection And Partial Liver Segment 2/3 Transplantation with Delayed total hepatectomy (RAPID) includes total hepatectomy in 2 steps with small graft transplantation at first stage. To avoid graft portal hyperperfusion, portal vein pressure monitoring is required after revascularization and right portal vein clamping. To date, portal flow modulation has not been reported but simulating hemodynamics in RAPID patients would be useful to anticipate these procedures. Our team developed hemodynamic 0D modeling; ...

Portopulmonary hypertension correlated with portal vein overload.

New Tools for Screening Children With Portal Hypertension.

Analyses of integrated EPID images for on-treatment quality assurance to account for interfractional variations in volumetric modulated arc therapy.

To investigate the effects of interfractional variation, such as anatomical changes and setup errors, on dose delivery during treatment for prostate cancer (PC) and head and neck cancer (HNC) by courses of volumetric modulated arc therapy (VMAT) aided by on-treatment electronic portal imaging device (EPID) images.

Clinico-epidemiological Profile of Extra Hepatic Portal Vein Obstruction: A Tertiary Care Hospital Based Retrospective Study.

Background Extra hepatic portal vein obstruction (EHPVO) is a common cause of portal hypertension in the developing countries (up to 30% of all variceal bleeders) and is second to cirrhosis in the West (up to 5-10%). Our understanding of the disease is poor compared with other illnesses. Objective To undertake a retrospective study of the clinicoepidemiological profile of Extra hepatic portal vein obstruction in a tertiary care hospital in eastern Nepal. Method All consecutive adult patients whose features ...

Ask-Upmark Kidney, Imaging Features.

Renovascular hypertension is known to occur due to varied causes. Absence of Renal artery stenosis or changes in renal vascular flow make it tough to establish a diagnosis of renovascular hypertension in the absence of invasive investigations. Segmental renal hypoplasia is not only a rare cause for renin mediated hypertension but also requires expertise and high index of suspicion while evaluating children with hypertension. We describe the classical imaging findings of a child with secondary hypertension w...

Liver Stiffness Assessed by Ultrasound Shear Wave Elastography from General Electric Accurately Predicts Clinically Significant Portal Hypertension in Patients with Advanced Chronic Liver Disease.

 Clinically significant portal hypertension (CSPH) is responsible for most of the complications in patients with cirrhosis. Liver stiffness (LS) measurement by vibration-controlled transient elastography (VCTE) is currently used to evaluate CSPH. Bi-dimensional shear wave elastography from General Electric (2D-SWE.GE) has not yet been validated for the diagnosis of PHT. Our aims were to test whether 2D-SWE.GE-LS is able to evaluate CSPH, to determine the reliability criteria of the method and to compare i...

Novel Classification of Nonmalignant Portal Vein Thrombosis: A guide to Surgical Decision Making during Liver Transplantation.

Nontumoral PVT is present at liver transplantation in 5% to 26% of cirrhotic patients, and the prevalence of complex PVT as defined here (Grade 4 Yerdel, and Grade 3,4 Jamieson and Charco) has been reported in 0% to 2.2%. Adequate portal inflow is mandatory to ensure graft and patient survival after liver transplantation. With time, the proposed classifications of non-tumoral chronic PVT have evolved from being anatomy-based to also incorporating functional parameters. However, none of the currently propose...

In compensated cirrhosis with portal hypertension, β-blockers reduced a composite of decompensation or death.

Porto-Pulmonary Venous Anastomosis: A Reversible Cause of Chronic Hypoxemia in Portal Hypertension.

Left-sided portal hypertension due to retroperitoneal fibrosis treated with an oesophagus preserving, modified Sugiura procedure.

Left-sided portal hypertension is a very uncommon condition and retroperitoneal fibrosis has rarely been reported as a cause. We present the case of a 77-year-old man with retroperitoneal fibrosis obstructing the splenic vein and causing recurrent episodes of upper gastrointestinal bleeding. Computed tomography showed a retroperitoneal mass as being responsible for the obstruction of the splenic vein, splenomegaly, and diffuse varices around the gastrosplenic and gastrohepatic ligaments. An oesophagus prese...

Restoration of liver sinusoidal cell phenotypes by statins improves portal hypertension and histology in rats with NASH.

Non-alcoholic steatohepatitis (NASH) is a common chronic liver disorder in developed countries, with the associated clinical complications driven by portal hypertension (PH). PH may precede fibrosis development, probably due to endothelial dysfunction at early stages of the disease. Our aim was to characterize liver sinusoidal endothelial cell (LSEC) dedifferentiation/capillarization and its contribution to PH in NASH, together with assessing statins capability to revert endothelial function improving early...

The role of anticoagulation in pylephlebitis: a retrospective examination of characteristics and outcomes.

Pylephlebitis, or suppurative thrombophlebitis of the portal vein, typically occurs in the context of an intraabdominal infection or abdominal sepsis. Antibiotics are the mainstay of treatment. The role of anticoagulation in the management of pylephlebitis is controversial, and data regarding its impact on outcomes is limited. The records of 67 consecutive patients with pylephlebitis treated at our institution over a 19 year period were retrospectively reviewed. Data was gathered regarding their baseline c...

Evidence of the Impact of the Tips From Former Smokers Campaign: Results From the Behavioral Risk Factor Surveillance System.

The Tips From Former Smokers campaign (Tips) has demonstrated significant impact as a population-based intervention for smoking cessation in the United States. Since 2012, evaluations of Tips have relied on web-panel data to attribute the campaign to smoking cessation outcomes. We re-examined the relationship between market-level doses of the campaign and quit attempts by using Behavioral Risk Factor Surveillance System (BRFSS) data to triangulate prior findings. We found that Tips was associated with incre...
