A delayed hemolytic transfusion reaction (DHTR) is the result of delayed anamnestic alloantibody response four to fourteen days after transfusion of apparently compatible blood. Most DHTRs are very mild and may not be recognized clinically. Some are manifested only by anemia. Only a few cases are severe enough to induce a massive hemolytic reaction followed by frank renal failure. Recently, we experienced a case of DHTR with acute renal failure (ARF) due to anti-E. A 21-year-old woman received compatible four units of packed red cells after right artificial total hip replacement arthroplasty due to juvenile rheumatoid arthritis. She had a history of transfusion 4 years ago. Fourteen days after the transfusion, she showed a fall in hematocrit, hemoglobinuria and a positive indirect antiglobulin test, and accompanied by ARF. Anti-E was identified in the patient's serum by antibody screening and identification test at that time. She recovered from ARF after hemodialysis with conservative management. However, eventually, she died due to disseminated intravascular coagulopathy.

A retrospective study of predictors determing outcome was carried out in a consecutive series of 104 patients, who had suffered from diffuse brain injury between December 1989 and April 1995, at the Department of Neurosurgery, Soonchunhyang University Hospital. The clinical, laboratory and radiological factors affecting the outcome in patients were analyzed and correlation between the factors and Glasgow outcome scale were statistically assessed. The major results were as follows: Significant predictors of poor outcome were old age, time interval within 5 hours from onset to admission, full dilated pupils or anisocoria, lower Glasgow coma scale, seizure, body temperature above 38 degrees C, PaO2 below 70mmHg, blood sugar above 160mg/dl, platelet count less than 100,000/mm3, prothrombin time less than 80%, lesions in more than 2 locations on CT & MRI and operative cases. Glasgow coma scale, age and temperature were demonstrated as the most significant predictors among the above factors by discriminant analysis. 2) Sex , kind of accidents, associated injuries, systolic blood pressure, pulse rate, respiration rate, PaCO2, base excess, serum sodium, bleeding time, coagulation time, and skull fracure were not significant influences on the outcome. According to the above results, the predictors of poor outcome should be considered as factors in assessing prognosis for treatment of diffuse brain injury.

OBJECTIVE: Microvascular decompression(MVD) for hemifacial spasm(HFS) is well established. However delayed postoperative facial palsy has not been substantially reported. The authors reviewed patients with HFS who underwent MVD in our institution to evaluate the post-operative courses with special attention to the development of delayed facial palsy. METHODS: Records of 144 cases(137 patients) from 1988 to 1997 were reviewed. Of these patients, 12(8.3%) developed delayed facial palsy. Follow-ups via chart and phone records were available for 10 of 12 patients. RESULTS: Reviews of these 12 cases demonstrated that 3 men, 9 women of with average age of 53(range 45-60) had delayed facial palsy. Among them, 2 had repeated operation. The preoperative duration of symptoms averaged 12 years(range 1-30) and 4 patients had mild preoperative weakness. All were improved their HFS within 7 days after MVD. Offending vessels were anterior inferior cerebellar artery(AICA) in 7. Five of these were meatal branches and 2 were sandwich type compressions. One case was combined compression of AICA and posterior inferior cerebellar artery. Three to 7 pieces of Teflon felt were necessary for the decompression of offender. The onset of weakness occurred invariably between postoperative day 6 and 11. Two cases had associated complications. The one was hearing loss and the other was meningitis accompanied by cerebrospinal fluid otorrhea. Ten cases received steroids following the onset of their facial palsies. Duration of follow up of 10 cases was 21months(3months-5years). Three cases showed complete recovery at 4, 8 and 12 weeks, respectively. Four patients have improved to House Grade II at 5 weeks and remaining three showed continuing improvement until last follow-up. CONCLUSIONS: Delayed facial palsy following MVD in HFS patients is not uncommon, being 8.3% in our series. It occurs consistently 1-2 weeks postoperatively. Possible causes include facial nerve exit zone injury with Teflon felt or delayed facial nerve edema. Spontaneous recovery usually occur within several weeks.

OBJECTIVE: The lack of anatomical knowledge for the anterior cervical microforaminotomy is liable to injure the neurovascular structures. The surgical anatomy is examined with special attention to the ventral aspect exposed in anterior cervical microforaminotomy. METHODS: In 16 adult formalin fixed cadaveric cervical spine, the author measured the distances from the medical margin of the longus colli to the medical wall of the ipsilateral vertebral artery and the angle for the ipsilateral vertebral artery. The distances from the lateral margin of the posterior longitudinal ligament to the medial margin of the ipsilateral medial wall of the vertebral artery, to the ipsilateral dorsal root ganglion was measured too. RESULTS: The distance from the medial margin of the longus colli to the ipsilateral vertebral artery was 13.3~14.7mm and the angle for the ipsilateral vertebral artery was 41~42.5 degrees. The range of distance from the lateral margin of the posterior longitudinal ligament to the ipsilateral vertebral artery was 11.9~16.1mm, to the ipsilateral dorsal root ganglion was 11.6~12.9mm. CONCLUSION: These data will aid in reducing neurovascular injury during anterior cervical approaches.

OBJECTIVE: Chronic hydrocephalus is one of the major complications following aneurysmal subarachnoid hemorrhage(SAH). However the incidence and predicting factors requiring shunting after SAH is not precisely known. The authors investigated the incidence of chronic hydrocephalus, timing of shunting procedure, and factors to predict the need for shunting in patients with aneurysmal SAH. PATIENTS AND METHODS: A series of 209 patients admitted to our institute from January 1993 to December 1997, who presented with SAH and underwent craniotomy for aneurysm clipping were studied retrospectively. Chronic hydrocephalus was defined as clinically and radiographically demonstrated hydrocephalus that lasted 2 weeks or longer after initial hemorrhage and that required shunting. The author divided study group into shunt group(SG, n=20) and non-shunt group(NSG, n=189). Patients were evaluated based on following factors: age, sex, history of hypertension and diabetes mellitus, consciousness at admission, Hunt-Hess grade, the presence of intracranial hemorrhage, Graeb's score, bifrontal index(BFI), Fisher grade, amount of SAH, location of aneurysm, time of aneurysm clipping, rebleeding, and vasospasm. RESULTS: The incidence of chronic hydrocephalus was 9.6%(20/209). The timing of the shunting procedure ranged from 16 days to 150 days after initial hemorrhage with the average being 77(+/-37)days. In a univariate analysis with chi-square test, age, consciousness, Hunt-Hess grade, amount of SAH, BFI, Fisher grade, and Graeb's score were significantly related with the need for shunting(p<0.05). In a multivariate logistic regression analysis, odds ratio was calculated for each variables. If the odds ratio of below 60 year of age was 1.0 then that of above 61 was 5.4(p<0.001). If the odds ratio of alert/drowsy was 1.0 then that of stupor/coma was 4.4(p<0.05). If the odds ratio of 0 of Graeb's score was 1.0 then that of 1-10 was 4.3(p<0.05). If the odds ratio of amount of SAH below score 3 was 1.0 then that of above score 4 was 1.8. If the odds ratio of BFI below 30 was 1.0 then that of above 31 was 1.1. CONCLUSION: The development of chronic hydrocephalus after aneurysmal SAH is multifactorial, but should be strongly suspected in patients with older age, decreased level of consciousness or IVH at admission. The patients require a shunt from 2 weeks to 5 months from the time of their initial hemorrhage.

Yakovlev demonstrated that the Schizencephalies appear to result from injury to developing cerebral vesicles in the second month of intrauterine life. There is a total loss of neurons in restricted symmetrical zones of each developing hemisphere and on either side of the resulting cleft-shaped defects are evidences of subtotal injury to developing neuroblasts. A case of a 4 years old male with Schizencephaly is reported.
