The maximal density of lymphatic capillaries in venous stasis was observed in persons of mature age and the minimal one--in elderly people. In adolescents and young people the number of lymphatic capillaries under conditions of the said pathology was found to be increased. The lymphatic bed of the oesophagus wall at early stages of the development of cirrhosis of the liver, apparently, ensured the outflow of the liquid from the organ tissues. As the disease developed, transudation of the liquid from sanguiferous capillaries exceeded the transport possibilities of the lymphatic bed, which led to the development of dynamic insufficiency of the lymphatic system.

The frequency of acute and chronic pancreatitis is 3.3 and 2.1%, respectively, in 107,754 adult autopsies in Japan. Acute pancreatitis is highly associated with liver diseases of various etiologies such as subacute hepatitis (16.1%), fulminant hepatitis (13.5%), biliary cirrhosis (10.5%), cholangiocarcinoma (8.6%) and postnecrotic cirrhosis (7.1%). Chronic pancreatitis is also closely related to various liver diseases. It is suggested that the portal venous stasis in liver diseases may predispose the patients to develop pancreatitis regardless of the etiology of liver diseases.

Portal hypertension is defined as an increase of the portal venous pressure over 20 cm H2O or 7 mm Hg, respectively. It may be induced by different types of portal venous stenosis or obstruction, primarily by cirrhosis and fibrosis of the liver and, less frequent by posthepatic disorders such as the Budd-Chiari-syndrome or congestive heart failure. Portal hypertension is followed by ectasia and phlebosclerosis of the portal vein, by splenomegaly, ascites and by various types of collateral circulation. Among these, oesophageal varices, are most important since they often lead to acute upper gastrointestinal haemorrhage, the major complication of portal hypertension. Bleeding from oesophaeal varices is essentially based on atrophy of the squamous epithelium, caused by ischemia from local hypoxia and venous stasis. Portal hypertension and the frequently compromised blood clotting mechanism due to reduced synthesis of clotting factors in the liver aggravate the bleeding. Atrophy of the esophageal mucosa presents an area of decreased resistance likely to ulcerate with easy erosion of the varices--usually lying very superficially--; with mechanical irritation by food or peptic erosion from gastroesophageal reflux being frequent inducers of hemorrhage.

From 1959 until 1981, 157 children were treated for portal hypertension by esophageal varices ligation in 13 cases and by portosystemic shunt in 144 cases. The age of the patients at operation was correlated with the cause of portal hypertension : mean age was six and a half years for cases with extra-hepatic blockage, and ten years for cases with cirrhosis. In 73% of cases, the shunt was undertaken following a bleeding episode from esophageal varices; at the present time, the decision to undertake a prophylactic type of shunt would be much more questionable. Central splenorenal shunt and mesocaval shunt were the operations most frequently performed by the different surgical teams in charge of these children (respectively 69 and 47 cases). Among the postoperative complications, three cases of venous stasis in lower limbs occurred after a mesocaval shunt; one child died two and a half years after a central splenorenal shunt from pneumococcal sepsis. During the last two years, there is a tendency in our group to perform a Warren shunt for intrahepatic portal hypertension, and a mesocaval shunt with jugular vein interposition in the case of extrahepatic portal hypertension. Recurrence of bleeding from esophageal varices after simple ligation has been observed in 64% of the cases; after portosystemic shunts, the anastomosis was a success in 89.3% of the cases. Whereas a significant fall in portal pressure after completion of the anastomosis is of good prognostic value, the fact that in some cases intraoperative measurement of pressure before and after shunting may show no difference does not imply a secondary thrombosis of the anastomosis, since this complication was seen in only 13% of the cases in these conditions.

Cirrhotic patients can develop thrombotic complications, which in this group of patients occur with a greater frequency than in the general population. Portal vein thrombosis (PVT) is the most common thrombotic phenomenon, although deep venous thrombosis and pulmonary embolism can also occur. Risk factors for thrombosis include inherited and acquired deficiency of factors involved in anticoagulation mechanisms, venous stasis of the portal vein owing to architectural derangement of the liver and possibly local factors related to the endothelium. Clinical manifestations of PVT range from asymptomatic disease to a life-threatening complication, and although it is no longer considered an absolute contraindication for liver transplant, its presence may require challenging surgical techniques, which entail greater morbidity. Anticoagulation therapy is henceforth an important strategy to treat cirrhotic patients with PVT, although experience in this group of patients is limited. Vitamin K antagonists and low-molecular-weight heparin have been used successfully, achieving recanalization of the thrombosed vessel in patients with cirrhosis; however, the precise drug regimen management and monitoring has not be fully explored in this group of patients.

Adults with congenital heart disease who underwent the Fontan operation to palliate single ventricle heart defects-by direct connection of caval venous return to the pulmonary circulation-have improved survival due to advancements in surgical and interventional techniques. However, cardiac and non-cardiac comorbidities often coexist, complicating management, and contributing to premature morbidity and mortality. Cardiac issues include heart failure symptoms related to systolic and diastolic dysfunction, atrial and ventricular arrhythmias and systemic atrioventricular valve regurgitation. Structural issues may be related to obstruction of the Fontan pathway, or to branch pulmonary artery stenosis, both of which exacerbate symptoms. Non-cardiac complications in adults involve hepatic congestion, fibrosis and cirrhosis, hepatocellular carcinoma, chronic kidney disease, stroke, venous stasis, lymphatic issues and involvement of other organ systems. 'Fontan failure' refers to circulatory dysfunction, either cardiac, non-cardiac, or both, diagnosed after exclusion or treatment of reversible contributors such as structural issues and arrhythmias. Counselling about reproductive health, mental health, perioperative management and overall wellness are paramount for patients' well-being. Fontan patients are typically managed in highly specialised adult congenital heart centres, but may present to cardiologists or other practitioners with cardiac and non-cardiac emergencies or urgencies, sometimes after being out of care. In this review, we discuss the management of the adult Fontan patient, including surveillance, cardiac and non-cardiac complications, reproductive health, and advanced therapies.
