Microsurgery therapy with Toth water dissection technique for patients with hypertensive intracerebral hemorrhage via lateral fissure approach

Objective To investigate the feasibility of microsurgery therapy with Toth water dissection technique for patients with hypertensive intracerebral hemorrhage via lateral fissure approach.Methods Forty-eight patients with hypertension basal ganglia cerebral hemorrhage,admitted to our hospital from January 2009 to January 2012,were selected in our study; they were divided into two groups according to different treatment methods:the observation group (n=24) chose Toth water dissection technique via lateral fissure approach and the control group (n=24) adopted surgery via lateral fissure approach.The operation time,postoperative coma time,hematoma clear rate,postoperative bleeding and activity of daily living (ADL) were compared between the two groups.Results Better results of operating time,postoperative coma time and hematoma clear rate in the observation group were noted as compared with those in the control group with significant differences (P＜0.05).All patients were followed up for 3 months; significant difference on ADL grading was noted between the observation group and the control group (Z=-1.998,P=0.046).The mean rank in the observation group (20.67) was obviously smaller than that in the control group (28.33),indicating that the prognosis in the observation group was better than that in the control group.No death was noted in the observation group while two in the control group.Conclusion Toth water dissection technique has better effect,enjoying smaller trauma,simpler operation,less time consuming and better protective effects on frontal and temporal lobes,in patients with hypertensive intracerebral hemorrhage as compared with traditional lateral fissure technology.
