Abstract
The study objective is to evaluate feasibility and effectiveness of decompressive craniectomy (DC) for treatment оf supratentorial hypertensive intracerebral hematomas (ICH).Materials and methods. Between 1996 to 2019, 97 patients with supratentorial hypertensive ICHs underwent surgical treatment. DC was performed in 50 patients (primary - in 41, secondary - in 9). Putaminal hematomas were diagnosed in 30 patients, subcortical - in 20. The comparison group consisted of 47 patients, of which 20 had osteoplastic craniotomy (OPC) with microsurgical removal of ICH, and 27 had endoscopic aspiration (EA). The performed DCa were treated as unjustified (decreased brain dislocation without prolapse of the brain substance into the trepanation defect), ineffective (preservation of brain dislocation and absence of prolapse of the brain substance into the trepanation defect, as well as small size of the trepanation hole) and effective (prolapse of the brain substance into the trepanation defect and regression of transverse brain dislocation).Results. DC was effective only in 22 (44 %) patients (13 - primary, 9 - secondary). Among patients with subcortical ICH, mortality rate after DC was equal to that after OPC and EA. Among patients with putaminal ICH, the mortality rate after DC was significantly higher than after OPC and EA. Among the patients who underwent primary EA and delayed DC (due to recurrent ICH), postoperative mortality rate was significantly higher than among the patients who underwent repeated EA of recurrent ICH. However, there were no fatal outcomes among patients who underwent delayed DC due to increased edema and transverse dislocation of the brain without recurrent ICH.Conclusion. In the surgical treatment of supratentorial hypertensive ICH, decompressive effect of DC was achieved only in 44 % of patients. Open removal of putaminal hematomas in combination with DC was unjustified, mortality rate was 66 %. Primary DC with removal of ICH is indicated in patients with subcortical hematomas with a volume >50 cm3 , with transverse dislocation >7 mm, deep deafness or sopor. Delayed DC, regardless of the location of ICH, is recommended in case of increased edema and transverse dislocation of the brain in patients without recurrent hemorrhage.
