[Treatment of portal hypertension].
The therapy of portal hypertension depends to a significant extent on its clinical manifestation. In cases of acute haemorrhage from oesophageal varices in patients with portal hypertension, the objective of the therapy is to stop the haemorrhage (endoscopically, or by compression by means of a balloon probe) and to decrease the pressure and the reflux within the portal vascular bed. Urgent sclerotisation under the simultanous pharmacologic decrease of portal hypertension is successful in 93-95%. There is an alternative procedure residing in introducing a balloon probe for several hours and subsequent repeated sclerotisation until a complete eradication of varices is achieved regarding the prevention of haemorrhage exacerbation. Urgent surgical solution is on the basis of the results of various investigated studies reserved for patients in whom endoscopic sclerotisation was not successful. Indication of surgical therapy must be also deliberated in candidates for liver transplantation, regarding the possible consequent technical problems after some types of interventions. Endoscopic sclerotisation of oesophageal varices is also an appropriate preparation for transplantation of the liver in patients with liver cirrhosis included into the transplantation programme. TIPS is a perspective new method in the therapy of portal hypertension of both, non-bleeding varices, as well as in other indications. It is also a certain intermediating link in therapy in some patients with liver cirrhosis on the waiting list of candidates for liver transplantation. Pharmacotherapy is a significant part of the portal hypertension therapy. It is appropriate to combine the endoscopic treatment with pharmacotherapy of portal hypertension in both, cases of acute haemorrhage, as well as in the prevention of haemorrhage exacerbation. In cases of acute haemorrhage, the combination of glypressin with nitroglycerin is justified, as well as the therapy by somatostatin. The prevention of haemorrhage exacerbations uses a whole series of vasoactive substances, especially nitrates, beta-blockers and ACE inhibitors. The prevention of the first bleeding includes the prophylactic therapy (endoscopic, pharmacologic, or surgical) recommended only in a selected group of patients under high risk of bleeding. The possible perspective option will reside especially in the combined pharmacological therapy, the fact of which will have to be proven in the future. (Fig. 1, Ref. 25.)
