biphasic or reverse flow in the portal vein(late stage): pathognomonicenlarged paraumbilical veins 8: pathognomonicManagement ultimately depends on the underlying etiology and the associated complications. Generally, management options include: 1. lifestyle modifications: dietary sodium restriction (e.g. for ascites) 2. medications: propranolol (e.g. for varices), diuretics (e.g. for ascites) 3. interventional procedures 3.1. creation of shunts: transjugular in...
Dilatation of splenic veins at the splenic hilum without splenomegaly may occur in situations such as a state of increased perfusion of splenic tissue associated with an immune response 6.
Colaterais, ou shunts portossistêmicos (SPSs), são comunicações anômalas entre o sistema portal e a circulação sistêmica, podendo ser congênitas ou adquiridas (7,8). Os shunts congênitos podem ser intra- ou extra-hepáticos, possuem classificação complexa e seu estudo vai além do escopo deste ensaio.

Suas causas são multifatoriais, compartilhando um mecanismo de elevação da pressão venosa portal, a qual pro-move o desvio do fluxo sanguíneo do trato gastrintestinal para a circulação sistêmica. Múltiplas vias de colaterais estão descritas na literatura, sendo congênitas ou adquiridas.
17 de jan. de 2024 · Cardiac wall. The cardiac wall or heart wall consists of the following layers from inside to the outside: endocardium. myocardium. epicardium. Heart valves. The outflow of each chamber is guarded by a heart valve: atrioventricular valves between the atria and ventricles. tricuspid valve. mitral valve (bicuspid valve)
A circulação colateral venosa que se desenvolve na esquistossomose e na cirrose podem ser igualmente reconhecidas pela ultra-sonografia, exceto pela maior freqüência de identificação da veia gástrica esquerda na esquistossomose.
