Objective To observe the mini -invasive treatment for patients with medium volume of hyper-tensive criatocapsular hemorrhage.Methods 59 patients with medium volume of hypertensive criatocapsular hemor-rhage(20 -30mL)were selected and randomly divided into mini -invsasive surgery group and conservative treatment group.Two groups were compared the average length of stay,hospital costs and clinical effect.Results The avergae hospital stay (14 ±3.26)days and avergae cost (1.1 ±0.33)ten thousand yuan of the mini -invsasive surgery group was lower than those of the conservative treatment group (25 ±6.58)days and (1.8 ±0.56)ten thousand yuan],the differences were statistically significant (t =7.999,5.768,all P <0.01).After 3 months follow -up,the recovery of self -care ability after operation estimated by ADL scores in the mini -invsasive surgery group was significantly better than that in the conservative treatment group(12 /31 vs.25 /28,χ2 =16.093,P <0.01).Conclusion For patients with medium volume of hypertensive criatocapsular hemorrhage(20 -30mL),minimally invasive surgery can shorten hospital stay,reduce the financial burden of patients,and improve the prognosis significantly.

Objective To study the clinical effect of microsurgical treatment via lateral fissure approach on hypertensive basal ganglia hemorrhage.Methods Small bone flap via lateral fissure approach were applied to remove basal ganglia hematoma.Thirty two cases were recruited in the retrospective analysis.Results By head CT scan follow-up 24 h post operation,over 80％ percent of hematoma was successfully removed in 28 cases and over 40％ of hematoma was resided in 4 case.Patients were followed up for 3 - 6 months,according to the ADL (ADL)classification,the outcomes were:Grade Ⅰ in 4 cases( 12.5％ ),grade Ⅱ in 13 cases(40.6％ ),grade Ⅲ in 12 cases (37.5％)and grade Ⅳ in 3 cases (9.4％).No death occurred.Conclusion Small window approach on lateral fissure for microsurgical operation of hypertensive basal ganglia hemorrhage is a less invasive procedure with good surgical exposure and homeostasis.Neurological function was well recovered after surgery.
