[Does decompressive craniectomy improve other parameters besides ICP? Effects of the decompressive craniectomy on tissular pressure?].

Second level therapeutic maneuvres for controlling intracranial hypertension (ICH) proposed by the European Brain Injury Consortium and the American Association of Neurological Surgeons include barbiturates, moderate hypothermia and more recently the decompressive craniectomy (DC).In most patients, ICP can be maintained below 25 mmHg after a DC. However, the exact effect of DC on brain oxygenation (PtiO2) still unclear. From our point of view the ptIo2 monitoring with the probe located in the healthy area of the most severely damaged cerebral hemisphere is not only a important tool for timing craniectomy in the future but also for evaluating the therapeutic effectivity of DC.
