Experiences of evacuation of basal ganglia hematoma in elderly patients via keyhole approach

Abstract

Objective To investigate the effect of evacuation of basal ganglia hematoma in elderly patients via keyhole approach. Methods Thirty-nine elderly patients with basal ganglia hematoma, admitted to our hospital from March 2011 and January 2011 and underwent keyhole microsurgery, were chosen in our study; and the clinical data, surgical methods and efficacy were retrospectively analyzed. Results According to the surface projection of hematoma tempus by preoperative CT, the surgery via keyhole approach was performed. The postoperative CT scan showed that the removal rate of all hematomas was 93%, removal rate of hematomas with diameter ranged from 3.6 to 6 cm was 97%, and that of hematomas with diameter exceeded to 6 cm was 85%. Re-bleeding was noted in two patients and cerebral infarction of hematoma periphery was noted in one patient. Glasgow outcome scale scores 6 months after operation indicated good results in 15 patients (38.46%), mild disability in 5 (12.82%), moderate disability in 7 (17.95%), severe disability in 3 (7.69%), and death in 9 (23.07%). Conclusion Evacuation of basal ganglia hematoma in elderly patients via keyhole approach has advantages as fast approach, short operation time, small volume of bleeding, and small damage to the cerebral cortex.
