title: [The importance of postoperative circulatory alterations in hepatic surgery].
abstract: There are two afferent (hepatic artery, portal vein) and one efferent (hepatic veins) systems responsible for the unique circulation of the liver. Given this special form of vasculature, acute, isolated (i.e. involving selectively one particular vessel) vascular occlusions may lead to different, however still life threatening conditions. Hence, it is essential to recognize these anomalies in order to preserve the healthy state of both the liver and the patient's lives. Acute circulatory failures are dominantly associated with liver surgery. Adequate therapy can only be provided promptly, if the clinician is well aware of the peculiarities of these conditions. The aim of this study is to overview the etiology and symptoms of these clinical conditions; furthermore to offer technical proposals for the required diagnostic and therapeutical steps via case reports. Furthermore, hepatic injury, caused by ischemia-reperfusion secondary to total vascular occlusion (Pringle maneuver) used in hepatic surgery is outlined.
