The aim of this study was to evaluate the incidence and the management of hydrocephalus following ruptured intracranial aneurysms. The authors analyzed 223 patients with aneurysmal subarachnoid hemorrhage(SAH) during the last two years retrospectively. The results are summarized as follows. Eighty patients(35.9%) showed ventricular dilatation on a brain CT scan. Twenty-five patients(11.2%) required shunt surgery. Hydrocephalus was closely related to the amount of hemorrhage and the location of the ruptured aneurysm. Two of 9 patients with acute hydrocephalus, who were managed by extraventricular drainage(EVD) before definite aneurysm surgery. The shunt surgery was done before aneurysm surgery in 16 patients and rebleeding occurred in 3 patients. Radioactive isotope(RI) cisternography diagnosed communicating hydrocephalus in 11 patients and the lumboperitoneal shunt was performed in those cases. It is concluded that hydrocephalus following aneurysmal SAH is the communicating type, an indication for shunt surgery could be determined by RI cisternography, and lumboperitoneal shunting seems to be the best treatment of choice to avoid rapid decompression of the ventricles and to protect the already compromised cerebral hemisphere. Decompression of the ventricles before aneurysmal surgery should be avoided whenever possible.

The effect of hyperbaric tetracaine spinal anesthesia was studied in 40 patients having genitourinary surgery in the horizontal lithotomy position. Patients were randomly assigned to one of two groups, after spinal injection, patients in one group were placed immediately in the supine and horizontal lithotomy position, and patients in the second group were placed immediatley in the supine and horizontal position for 10 minutes and then placed into the horizontal 1thotomy position. There were no statistically significant differences in anesthesia sensory level and heart rate of patients placed immediately in the horizontal lithotomy position compared to the patients kept in the supine position for the first 10 minutes after receiving the spinal anesthetic. The ranges of systolic blood pressure were all within normal limits, although systolic blood pressure showed a difference at 5,10 and 60 minute intervals after anesthesia. We conclude that immediate application of the horizontal lithotomy position can be safely practiced in the anesthesia of genitourinary surgery.

Most trauma induced fistulas are direct communications between the intracavernous carotid artery and the cavernous sinus. Theses abnormal communications are characterized by high pressure, high blood flow and a clinically obvious constellation of symptoms and signs. We here in report a patient with traumatic carotid cavernous sinus fistula(CCSF). who developed central retinal vein occlusion(CRVO) during detachable balloon embolization. The mechanism of CRVO occurring during detachable balloon embolization. The mechanism of CRVO occurring during detachable ballon embolization for CCSF was discussed. We report this case with the review of previous reports.

In order to compare the amount of surgically induced astigmatism among sutureless group(Group 1),10-0 nylone suture group(Group 2),and using tissue adhesive group(Group 3),we analysed a series of rabbit cataract surgery cases in these three groups. We performed cataract surgery on 30 eyes of 15 rabbits by Irrigation and aspiration technique. After cataract surgery,10 eyes by sutureless technique,10 eyes were closed by conventional 10-0 nylon suture technique, and 10 eyes by tissue adhesive(Beriplast) technique.We collected keratometric data before and after surgery(At 1,2,4,8 weeks).In postoperative astigmatic change,three groups had the distinct features in the evolution for postoperative astigmatism.The group 1 showed early against-the-rule(ATR)astigmatism,which advanced ATR and showed about 0.5D astigmatic change at 8 weeks.The group 2 showed early with-the-rule(WTR)astigmatism about 1.13D,which advanced toward ATR from 1week.The group 3 showed little ATR about 0.2D,which was minimal change in astigmatism.At 8 weeks after operation,there was no signifi-cant difference in the astigmatic change among the three groups(P>0.05), which were no complications observed. In this study,the tissue adhesive(Beriplast)seem to be a simple,effective and less induced astigmatic changing corneoscleral suture technique than other suture techniques

To evaluate the cerebral blood flow in feline hydrocephalic brain, this study was designed to measure the regional cerebral blood flow(rCBF;frontal and periventricular area) by the hydrogen clearance method in different stages of the kaolin-induced hydrocephalus and the postshunt status. The results were as follows: 1) A reduction of rCBF was detected in the left periventricular area at two weeks after kaolin injection. A significant reduction of rCBF was revealed in the left periventricular area at two and four weeks after kaolin injection. However, the rCBF of the left frontal cortex was significantly decreased at four weks after kaolin injection. 2) At one week after shunt operation, the significant restroration of rCBF was found in the left frontal cortex and the left periventricular area.

The diffuse nodular lung lesion has a diagnostic problem and should be made differential diagnosis. A chest X-ray of 62-year-old male patient with dyspnea showed small-sized scattered multinodular lesion on entire lung field. Bronchoalveolar lavage and transbronchial needle aspiration showed the non-specific findings, so open lung biopsy was done and revealed bronchioloalveolar cell carcinoma.

Radiotherapy is a standard postoperative treatment for various cerebral neoplasms. Howewr, radiation has the potential to produce severe injury to normal brain tissue in and around the tumor bed. The authors encountered 7 patients with delayed cerebral necrosis. These unacceptable complication prompted us to analyze cases with such a complication particularly in regard to the differential diagnosis between the recurrence of the tumor and radiation necrosis of the brain. This article summarizes factors related to the radiation necrosis, including clinical observations and treatment.

To localize bypass pathways, left and right ventricular regions were analyzed at rest by phase image analysis in 6 patients with Wolff-Parkinoson-White syndrome and 5 patients with concealed bypass pathway. These were compared with image findings in 12 normal subjects. In normal subjects, the earliest emptying occured in ventricular septal, apical and left basal segments. Mean difference between the earlist left and right ventricular phase angle was 2.3+/-5.6degrees in patients with normal conduction, -14.0+/-15.1degrees in patients with left bypass pathways, 15.0+/-0degrees in patients with right bypass pathways and -6.6+/-12.3degrees in patients with concealed bypass pathways. In patients with bypass pathways, there was complete agreement between phase and electrophysiologic maps, but incomplete agreement(4 of 6) between surface ECGs and electrophysiologic map in a patient with left posterior and left bypass pathways. The phase image represents a new, noninvasive method of evaluating ventricular pre-excitation. The method may provide useful information complementary to that of electrocardiographic and electriphysiologic analysis.

Twenty-nine patients haboring primary or recurrent malignant gliomas were treated with direct implantation of radioactive sources into the tumor in afterlozded, removable catheters using stereotatic technique between November 1987 and October 1990. Indine-125(I-125) was implanted in 22 patients and high dose rate(HDR) Iridium-192(Ir-192) in 7 patients. All patients had been treated with external radiation and most had been treated with chemotherapeutic agents. one or more sources were placed in each tumor to deliver 5000-8000 cGy to the tumor's periphery for I-125 and 3000 cGy for HDR Ir-192. Eleven of 13 patients with glioblastoma multiforme were alive at 35 weeks whose mean survival was 74 weeks, and remained two were expired at 35 and 78 weeks, respectively. All 5 patients with anaplastic astrocytoma were alive at 39 weeks whose mean survival was 74 weeks. Five of 9 recurrent blioblastoma were alive at 22 weeks whose mean survival was 44 weeks, and remained three were expired at 13, 17 and 22 weeks respectively. All two patients with anaplastic astrocytoma were alive at 22 and 52 weeks, respectively. Four patients with deep seated analphastic astrocytoma(3 in the thalamus and 1 in the third ventricle) were treated successfully by brachytheray without any surgical morbidity and mortality and they were still alive 38, 48, 74 and 123 weeks after brachytherapy. There were few minor postoperative complications including 3 meningitis. 2 leak of cerebrospinal fluid and 3 radiation necrosis without any mortality. The authors conclude that the brachytherapy with temporary implanted I-125 or Ir-192 sources may provide long-term survial in selected patients with primary or recurrent malignant gliomas.
