Abstract
BACKGROUND: Basal cisternostomy (BC) recently emerged as an adjuvant/alternative procedure to decompressive craniectomy (DC) in traumatic brain injuries (TBIs) with its potential to effectively reduce both intracranial pressure (ICP) and brain edema. However, its role in TBI is not yet established in the true sense and with clarity. The objective of the present study was to evaluate the effect of adjuvant BC on ICP, mortality, and clinicoradiological outcome. METHODS: A single-center randomized control trial was conducted. Fifty patients were assigned to each DC-group and DC+BC-group. Randomization was done using the sealed envelope method. Both groups were followed in the postoperative period to compare the impact of surgery on ICP, radiological changes, and clinical outcome (mortality, days on ventilator/in intensive care unit (ICU), and Glasgow outcome scale-extended (GOS-E) at 12 weeks). RESULTS: Both groups were comparable in terms of preoperative clinicoradiological characteristics. On postoperative days 1, 2, and 3, mean ICP was significantly low in the DC+BC-group (P < 0.0001). The decline in ICP in the DC+BC-group was significant in both moderate and severe TBI patients. In comparison, DC+BC-group has a shorter duration of mechanical ventilation/ICU stay and significantly better GOS-E score at 12 weeks (P < 0.0001*). The mortality rate was less in the DC+BC-group (48%) as compared to the DC-group (64%). Among radiological features, mean midline shift and mean outward brain herniation were significantly less in the DC+BC group. Bone-flap replacement was possible in ten patients of DC+BC-group at the time of primary surgery. CONCLUSION: Results of our study indicated that BC is beneficial in reducing both ICP and brain edema, which translates into favorable clinicoradiological outcomes.
