Abstract
Objectives: This study assesses the benefits of adapting minimal invasive techniques (MIT) to selected patients with spontaneous supratentorial intracerebral hematomas (SSICHs).
Methods: The study compares the post-operative residual clot volume and clinical outcome of 89 selected, MIT evacuated SSICH-patients to those of 138 unselected cases operated in our department. Selection criteria includes patient age, early admission and MIT treatment. MIT treatment included: 28 patients with deep SSICHs smaller than 30 cm3 associated with intraventricular bleeding who underwent neuronavigation-guided stereotactic catheter lysis, 37 patients with deep hematomas larger than 30 cm3 and 24 patients with a lobar hemorrhage compressing eloquent regions who underwent microsurgical (endoscopic or neuronavigation assisted) clot aspiration.
Results: In eight (9%) of the patients in the MIT group, the CT scan control showed a residual clot smaller than 30% of the initial hemorrhage. The neurological condition 3 months later revealed 24 (26.9%) of these patients having a severe disability and 46 (51.6%) patients independent or slightly disabled. Nineteen patients (21.9%) died or remained vegetative. In the control group, 48 (34.7%) cases showed residual clots (<30%). Sixty-two (44.9%) patients of this group were severely disabled and only 40 (28.9%) were independent. Thirty-six (26%) patients died or were vegetative. There was a p<0.001 significant difference in volume of residual clots as well as p<0.01 for the outcome between the two groups.
Conclusions: Adapting minimally invasive techniques to case selection improves the effectiveness of clot removal and the outcome of the patients with SSICHs.
