Comparative Clinical Analysis of Surgically Treated Spontaneous Intracranial Parenchymal Hematoma between with Stereotaxic Evacuation and Free-Hand Craniectomy

From Jun, 1983 to Sep, 1986, we operated 127 cases of spontaneous intracranical parenchymal hematoma. Among them, 88 cases were operated by stereotaxic evacuation of hematoma with computed B.R.W. system and 39 cases by free-hand craniectomy and leucotomy. We compared results of both methods. Results are as followings : 1) Nearly 90%(112 cases) were over 40 years old. 2) Prevalence of both sex were nearly same. 3) Hypertension cases on admission were 93 cases(73.2%). 4) Favorite anatomical locations were putamen(55 cases ; 43.3%), thalamus(32 cases ; 25.2%), subcortical(29 cases ; 22.8%), pontine, cerebellum in frequency. 5) Amount of removed hematoma were mostly 10-30ml and upper most case was 145ml. 6) Irrigation with urokinase were done in cases. 7) Surgical complication were 7 cases(5.5%) : 6 cases of reblecding : 1 case of ventriculitis. 8) Mortality of total cases were 26.0%(33 cases). 9) Comparative results between B.R.W. group and F.H.C. group were as followings ;(tab)B.R.W. group(tab)(tab)F.H.C. group(tab)(newline)Mortality(tab)13.60%(tab)(tab)28.20%(tab)(newline)(tab)AD(tab)DC(tab)AD(tab)DC(newline)Glasgow coma scale(tab)11.23+/-3.14(tab)12.72+/-3.87(tab)8.56+/-3.33(tab)10.97+/-4.93(newline)Motor power(tab)2.59+/-1.14(tab)3.44+/-1.27(tab)3.05+/-1.21(tab)3.32+/-1.53(newline)Motor of Putaminal Hx(tab)2.38+/-0.85(tab)3.13+/-1.00(tab)3.20+/-0.94(tab)3.00+/-1.41(newline)

Roles of BRW CT Stereotaxic in Less Accessible Brain Lesions

With improvement of computerized tomography(CT), stereotaxic surgery has been applied for neurosurgery ; aspiration of deep-seated brain lesions, radiotherapy using a small radiogenic sources, and evacuation of hematoma. And so, a prototype Brown-Roberts-Wells(BRW) CT stereotaxic system has been avaible to us. We report its utilization in evaluation and management of less accessible brain lesions. Surgical exploration was undertaken in 25 patients with various less accessible brain lesions using BRW system : 9 superficial lesions including the motor cortex and multiple lesions, 5 deep-seated lesions, 3 parasellar lesions, 8 brain stem lesions. Histologically, there are 5 gliomas, 4 metastatic cancers, 8 hematomas, 3 brain abscesses, 1 medulloblastoma, 1 malignant melanoma, 1 cryptic AVM, and 2 undiagnosed cases. There are two complications : 1 intratumoral bleeing, 1 rebleeding. The diagnostic rate is 92%. There is no mortality in this series. This BRW CT-guidance stereotaxic approach for less accessible lesions have following advantages ; 1) accurate, simple and safe ; 2) performed under local anesthesia ; 3) less traumatic and low cost ; 4) easily diagnosed ; 5) relatively no limitation in lesion sites.
