The authors present a case of multiple intracranial calcifications after the procedure of external ventricular drain placement in a 50-year-old man with pericallosal artery aneurysm. We believe that calcifications formed dust that had fallen into the track during the external ventricular drain procedure. The clinical features and radiological findings are presented with review of literature.

Purpose: This study was done to develop an evidence-based external ventricular drainage (EVD) nursing practice guideline in order to provide standardized nursing and prevent EVD related complications. Methods: We used the standardized methodology for nursing practice guideline adaptation developed by Korean Hospital Nurses Association for the guideline adaptation process in this study. Results: The newly developed EVD nursing practice guideline was adapted to the American Association of Neuroscience Nurses (AANN)'s clinical practice guideline which is 'Care of the patient undergoing intra-cranial pressure monitoring/external ventricular drainage of lumbar drainage.' There were 61 recommendations documented in the preliminary guideline all evaluated by 9 experts based on acceptability and applicability. The final practice guideline was composed of 3 domains with 57 recommendations. The three domains of nursing were the insertion, maintenance, and removal of the EVD. The number of recommendations in each domain was 8 in EVD insertions, 39 in EVD maintenance, and 10 in EVD removals. Of the 57 recommendations 3.5% were level 1, 31.5% were level 2, and 65% were level 3. Conclusion: The standardized practice guideline can improve nurses' performance and accuracy. It can also be used as the foundation for effective communication between all medical staff.

Objective : The aim of this study is to determine which patients with progressively deteriorating acute cerebellar infarction would benefit from surgical treatment and which surgical procedure would best benefit them. Methods : Seventy six patients were treated at our hospital for cerebellar infarction over the past 3 years. Sixty nine patients received conservative management in the neurological department of our hospital. Among them, 7 patients [5 males and 2 females; average age, 49 yrs] were referred to neurosurgical department because of mental deterioration and underwent emergency surgery. Five patients underwent external ventricular drainage with suboccipital craniectomy and two patients underwent suboccipital craniectomy alone. Results : Of the 7 surgically treated patients, 4 patients experienced good recovery and 2 patients experienced moderate disability [disabled but independent] and 1 patient experienced severe disability [conscious but disabled]. There was no death. Conclusion : In patients conservatively treated for cerebellar infarction and showing mental deterioration and radiologically evident brainstem compression and ventricular enlargement, we strongly recommend suboccipital craniectomy [plus optional external ventricular drainage in case of showing hydrocephalus] as a first treatment option.

Thirty nine-year-old man who required urgent shunt operation due to rapidly deteriorating visual acuity suffered from ventriculitis after aneurysmal operation. Daily dose of 20mg of vancomycin and amikyn were given intraventricularly via external ventricular catheter after failure of various kinds of systemic antibiotics. The exit of the catheter was made on the upper chest wall to prevent superinfection. External ventricular drainage could finally be switched to ventriculo-peritoneal shunt and he was discharged with clinical improvement.

Objective : The aim of this study is to analyze on the external ventricular drainage [EVD] related ventriculitis, especially on their risk factors, management, and prevention. Methods : From January 2003 to December 2005, a total of 174 EVD catheters were placed in 112 patients at our institution. Of these patients, EVD-related ventriculitis were developed in 15 cases. Clinical variables such as age, sex, prior clinical diagnosis, placement of EVD insertion, duration of EVD, total numbers of EVD per person, and outcome were analyzed in theses cases to verify the risk factors, causative agents and outcomes. Results : Fifteen cases of EVD related ventriculitis were noted presenting infection incidence of 13.39 % per patient and 8.62% per procedure. Of these, five patients died from sepsis, seven patients were recovered from infection but neurological complications remained and three patients were recovered without any complications. Microbes were obtained from cerebrospinal fluid only in six patients. Acinetobactoer baumanii was the most common pathogen in our study [4 cases]. Among the various risk factors, only the prior clinical diagnosis showed the statistical significance. Patients who underwent decompressive craniectomy after severe brain trauma showed unfavorable outcome because of possible contaminative environment compared with other cases. Conclusion : EVD is considered as a safe procedure with good control of intracranial pressure if meticulous care is provided for EVD procedure and maintenance. With regards to risk factors and prevention, the higher incidence and unfavorable outcome was seen especially in patients with severe head trauma. Thus, special attention is required in these clinical settings.

A 64-year-old man was admitted to our hospital in semicomatous consciousness. Brain computed tomography scans demonstrated $2.6{\times}2.5\;cm$ sized hyperdense mass in the pineal region with multiple punctate calcifications and hydrocephalus. Brain magnetic resonance imaging demonstrated a pineal mass which was heterogeneously enhanced with gadolinium. After external ventricular drainage, the patient regained consciousness. The mass was totally removed via occipital transtentorial approach. No consequent ventricular shunt was needed and the patient recovered without any neurological deficit. Final pathologic report of the tumor was ependymoma.

Takotsubo or reverse Takotsubo cardiomyopathy is a well-known cardiac complication of subarachnoid hemorrhage (SAH) that shows transient left ventricular wall motion abnormalities with electrocardiogram (ECG) changes. ST change followed by T inversion is a common ECG finding complicated with these disorders, left bundle branch block (LBBB) may be a potential ECG pattern which is seen. In this case, we describe the clinical profile and outcomes of a patient with LBBB and reverse Takotsubo cardiomyopathy after anesthetic induction, which was scheduled as an emergent external ventricular drainage after SAH. This is the first report of an LBBB pattern in reverse Takotsubo cardiomyopathy.

Objective : The purpose of this reports is to describe the influence of continuous external ventricular drainage [EVD] on delayed ischemic neurologic deficit [DIND] after early surgery in ruptured aneurysmal patients. Methods : The authors reviewed 229 patients with aneurysmal subarachnoid hemorrhage [SAH] who had been treated with clipping at a single institution between 1998 and 2004. Of these, 121 patients underwent continuous EVD [Group A] postoperatively, whereas 108 patients did not [Group B]. EVD was performed at ipsilateral Kocher's point and maintained 2 to 14 days postoperatively. Results : DIND occurred in 15.7% [19 cases] of patients in Group A, 25% [27 cases] from Group B [P value=0.112]. Compared with Group A, Group B was more likely to suffer acute symptom of DIND and showed poor response to 3- H therapy. Major symptoms of DIND in Group A were mild confusion [36.8%] and mild deterioration of mental state [26.3%], contrary to weakness of extremities [59.2%] in Group B. At discharge, Glasgow Outcome Scales [GOS] of Group A were : good recovery [63.2%], moderately disabled [21%], severely disabled [10.5%], dead [5.3%] and Group B : good recovery [48.1%], moderately disabled [37%], severely disabled [14.8%] and dead [0%]. Of 121 patients from group A, 35 patients [28.9%] suffered ventriculitis. Conclusion : Continuous EVD after aneurysmal clipping in patients with SAH reduced the risk of DIND and its sequelae, relieved its symptoms, and improved the outcome.

Objective : This paper presents data from a retrospective study of endoscopic third ventriculostomy (ETV) in patients with shunt malfunction and proposes a simple and reasonable post-operative protocol that can detect ETV failure. Methods : We enrolled 19 consecutive hydrocephalus patients (11 male and 8 female) who were treated with ETV between April 2001 and July 2010 after failure of previously placed shunts. We evaluated for correlations between the success rate of ETV and the following parameters : age at the time of surgery, etiology of hydrocephalus, number of shunt revisions, interval between the initial diagnosis of hydrocephalus or the last shunt placement and ETV, and the indwelling time of external ventricular drainage. Results : At the time of ETV after shunt failure, 14 of the 19 patients were in the pediatric age group and 5 were adults, with ages ranging from 14 months to 42 years (median age, 12 years). The patients had initially been diagnosed with hydrocephalus between the ages of 1 month 24 days and 32 years (median age, 6 years 3 months). The etiology of hydrocephalus was neoplasm in 7 patients; infection in 5; malformation, such as aqueductal stenosis or megacisterna magna in 3; trauma in 1; and unknown in 3. The overall success rate during the median follow-up duration of 1.4 years (9 days to 8.7 years) after secondary ETV was 68.4%. None of the possible contributing factors for successful ETV, including age (p=0.97) and the etiology of hydrocephalus (p=0.79), were statistically correlated with outcomes in our series. Conclusion: The use of ETV in patients with shunt malfunction resulted in shunt independence in 68.4% of cases. Age, etiology of hydrocephalus, and other contributing factors were not statistically correlated with ETV success. External ventricular drainage management during the immediate post-ETV period is a good means of detecting ETV failure.

Objective : Hydrocephalus and vasospasm are the common complications following subarachnoid hemorrhage (SAH). In spite of development of perioperative management and operative technique, hydrocephalus cause neurological deficit and poor prognosis. Usually CSF drainage procedure(external ventricular drainage(EVD) or shunt) is needed in hydrocephalus following SAH. The aim of this study was to investigate whether the need for shunting and the outcome after shunting in hydrocephaus following SAH can be related to the duration, daily and total amount of cerebrospinal fluid(CSF) drainage at EVD. Material and Method : IVH is one of several factors which cause hydrocephalus. In this retrospective study, firstly we investigated the incidence of IVH in total cases and frequency of IVH according to aneurysmal site and then prognosis of IVH following SAH. Among 629 patients with SAH, hydrocephalus was diagnosed by CT scan and symptoms. And then those 102 hydrocephalus following SAH were divided into two groups which were hydrocephalus with IVH group and without IVH group. In these two groups, we investigated and compared the incidence of hydrocephalus in all case, frequency of hydrocephalus according to aneurysmal site, the outcome according to H-H grade on admission and the need rate of shunt, etc. Of those hydrocephalus, 100 EVD procedures were done. The duration, daily and total amount of CSF drainage at EVD were investigated. Fifty cases expired during EVD was excluded. We analyzed whether the need rate of shunt and the final outcome after shunting can be related to IVH, the duration and daily and total amount of CSF drainage. Result : The incidence of hydrocephalus following SAH was 20%(with IVH group ; 64%, without IVH group ; 11%). As H-H grade on admission was better, the outcome of hydrocephalus was also better. The mortality rate of hydrocephalus with IVH was 64% which was higher than 40% that of hydrocephalus without IVH. The need rate of shunt in all cases of hydrocephalus following SAH was 20%, but those with IVH group excluding expired patients before shunt was 40%. This was very similar to 41% of the need rate of shunt in hydrocephalus without IVH. The total amount of CSF drainage was statistically related to the need rate of shunt(total amount : need rate of shunt/<1000cc : 15%, 1000-2000cc : 40%, >2000cc : 50%). The duration and daily amount of CSF drainage were not statistically related to the need rate of shunt, but as daily amount of CSF drainage was more and duration was longer, the need rate of shunt was increased(daily amount : need rate of shunt /<100cc : 16%, 100-200cc : 25%, >200cc : 40%//duration : need rate of shunt/<1week : 8%, 1-2weeks : 30%, >2weeks : 47%), and also the final outcome after shunting was poor. Especially the total amount of CSF drainage was significant related to the final outcome after shunting(total amount : GOS/<1000cc : I&II(3/4), 1000-2000cc : II(2/4), III(2/4), >2000cc : III&IV(6/7)). Conclusion : This study revealed that the incidence and mortality rate of hydrocephalus following SAH were influenced by IVH. So SAH associated IVH has the higher incidence of hydrocephalus and poor outcome. As the CSF drainage amount was more and duration of drainage was longer, the need rate of shunt was increased and the final outcome after shunting was poor. Especially the total amount of CSF drainage were strongly related to the need rate of shunt and the outcome after shunting.
