In the immediate postoperative period the state of the regional blood circulation depends on the insufficient myocardiac function and organic changes in the organs-targets. Under these conditions the correction of portal hypertension (PH) is the impotant object of the conservative therapy. Isosorbid dinitrat (Isoket), which is used for this, effectively reduces the PH level. It is accompanied with the improvement of organic blood circulation and myocardiac function. It is particulary important to take these afteroperative changes into consideration in surgical patients with IDH.
