[Intraabdominal pressure alterations in ruptured abdominal aortic aneurysms].

The authors investigated the dependence of intraabdominal pressure on the volume of a retroperitoneal haematoma. The study included a total of thirty-four patients in whom elevation of intraabdominal pressure had solely been caused by haemorrhage into the retroperitoneal space. The volume of the retroperitoneal haematoma was calculated based on the findings of spiral computed tomography, whereas intraabdominal pressure was measured using the methods suggested by Sugrue M. and Kron I. L. The statistical analysis showed a moderate positive correlation between the retroperitoneal haematoma volume and the level of intraabdominal pressure. With the volume of the retroperitoneal haematoma approximating to 2,000 ml, intraperitoneal pressure was at the upper limit of the norm. Of the patients examined, none turned out to have developed the high intraperitoneal pressure syndrome.
