Objective: Classical surgical therapy of ICH (i.e. haematoma evacuation) remains controversial, following the results of the STICH study. Decompressive hemicraniectomy (DC) prove beneficial results in cases of malignant middle cerebral artery infarction. First clinical studies suggested that DC may be a promising treatment option for ICH, too. To test the hypothesis of beneficial treatment effects of DC in ICH we used a multimodal monitoring approach in porcine ICH.

Method: We investigated the effect of DC for ICH treatment in an animal model with 6 pigs. Beyond vital signs (RR, HF, sPO2, CO2 exsp, BGA, etc.), multimodal monitoring (ICP, pTO2, micro dialysis (Glutamate, pyruvate, lactate, glucose), CBF) of the perihaemorrhagic zone was performed. Monitoring duration was 12 hours.

Results: DC showed significant long-term reduction of ICP from 12 to 5mmHg. After ICH pTO2 was continuously decreasing. There was also a significant but only temporary improvement of pTO2 from 9 to 13mmHg. This means the continuously decrement of pTO2 after DC was delayed for one hour. There was no long-term improvement from DC on pTO2. Micro dialysis values only showed temporary improvements on the perihaemorrhagic zone comparable to the pTO2 effect.

Conclusions: After experimental ICH DC did improve ICP. PTO2 and metabolism in the perihemorrhagic zone showed only short-time improvement after DC. Short-term improvements of pTO2 and metabolism of the perihemorrhagic zone are disappointing. However, if DC is an useful treatment in ICH further investigations have to be done.
