One hundred cases of anterior communicating artery aneurysms, operated upon during a 10-year period from 1977 to 1987, were analysed to study the microsurgical anatomy of the aneurysms. All of the cases were operated by direct intracranial approach using a operating microscope. Findings of preoperative four-vessel angiogram, operative microphotographs, operative microvideo tapes, and operator's drawings with narratives were investigated on in order to provide the detaild microsurgical anatomy of the aneurysms to obtain the classification according to it. The results were as follows; 1) The anatomical variations of the anterior portion of circle of Willis were as follows;right A1 hypoplasia in 23 cases, left A1 hypoplasia in 9 cases, left A1 aplasia in 3 cases, duplication of anterior communicating artery in 3 cases, and fenestration of anterior communicating artery in 1 case. 2) The diameter of the aneurysm was as follows;5-10mm in 73% below 5mm in 16%, and over 10mm in 11%. 3) Classification of the anterior communicating artery aneurysms according to its direction were as follows;anterior directions in 65%, posterior directions in 16%, superior directions in 10%, inferior direction in 9%. 4) The frequency of hemorrhage were as follows;One bleeding in 65%, Two bleedings in 25%, more than three bleedings in 10%. 5) The vasospasm was observed in 26%, the hydrocephalus in 44%. 6) The posteriorly directing aneurysms showed worse preoperative state than anteriorly directing ones, and the diameter and the direction of anterior communicating artery aneurysm has no relationship with hydrocephalus, vasospasm, and rebleeding. 7) Overall mortality was 5%. Psychotic disturbance, one of the significant complications of rupture of the anterior communicating artery aneurysms, was observed in 13% and among these 6% were observed after operation. Frontal lobe syndrome, organic brain syndrome, depression, confusion, mutism, memory disturbance were manifestations of psychotic disfurbances.

Meningiomas had long been considered radioresistant and therefore the role of radiation therapy in its treatment remains controversial. Lately, however, most of the retrospective analysis of meningiomas indicates that radiation therapy does show some degree of beneficial effects not only for malignant but also for benign meningiomas with the advanced technology and increased amount of radiation therapy, the rate of growth of tumor had been successfully slowed and local recurrence rate is also reduced following subtotal resection. We have performed conventional high dose radiation therapy on 7 cases of meningiomas(four cases of meningotheliomatous meningiomas, and three cases of malignant meningiomas). Of the 7 cases, the residual mass of 6 had decreased in size and neurological improvement was also evident. However, the 7th case resulted in complicated hydrocephalus. These cases are presented and the effect of conventional radiation therapy is discussed together with the review of literatures.

Surgical resection may not be the appropriate first treatment for all intracranial mass lesions, especially for deep or midline lesions. And a precise histopathological diagnosis is mandatory to develop adequate and specific treatments. The advent of modern imaging and CT-compatible stereotactic frames has greatly simplified the performance of streotactic procedure for small and deep seated brain tumors. We present a 44-month experience on 94 stereotactic procedures of intracranial mass lesions, using Brown-Roberts-Wells(BRW) and Cosman-Roberts-Wells(CRW) system. Procedures were undertaken with the patient under the local anesthesia for biopsy(78 procedures), cyst aspiration and/or Ommaya reservoir insertion(9 procedures), and brachytherapy(5 procedures) and under the general anesthesia for stereotactic-guided microsurgery(2 procedures). Procedural objectives were satisfactorily accomplished with no mortality and an overall complication rate of 8.5%(8 of 94 procedures). The postoperative complications were transient and not seriour, except aggravation of obstructive hydrocephalus in two cases of lateral ventricular tumors. Specific and correct histological diagnoses were achieved in 73(94%) of 78 biopsy. We could not obtain a specific diagnosis in 3 cases(2 cases of reactive gliosis, 1 case of necrosis). And in two cases with a diagnosis of anaplastic astrocytoma and oligodendroglioma grade I on the basis of surgical specimens by craniotomy, stereotactic biopsy revealed astrocytoma grade II and nonspecific inflammation respectively. Our data suggest that CT-guided stereotactic biopsy is a reliable and safe method for histologic diagnosis of brain-tumoral conditions and the method of choice for deep-seated and midline lesions.
