2.Decompressive Craniectomy in Traumatic Brain Injury: A Review Article.
Korean Journal of Neurotrauma 2017;13(1):1-8
The importance of treating traumatic brain injury (TBI) is well known worldwide. Although many studies have been conducted in this topic, there is still much uncertainty about the effectiveness of surgical treatment in TBI. Recently, good randomized controlled trial (RCT) papers about the effectiveness of decompressive craniectomy (DC) in TBI has been published. In this article, we will review the overall contents of the DC (historical base, surgical technic, rationale, complications) and the results of the recently published RCT paper.

OBJECTIVE: Measurement of intracranial pressure(ICP) is important in patients at risk of raised ICP. To evaluate the usefulness of measuring epidural pressure measurements for the estimation of intracranial pressure, we studied the relationship between epidural pressure and ventricular pressure. PATIENTS AND METHODS: From Nov. '97 to Jul. '98, 10 patients of extraventricular drainage(Group A) and 12 patients of decompressive craniectomy(Group B) are included in this study. Simultaneous recording of intracranial pressure (ICP) from an air-pouch epidural pressure monitoring system and a ventricular catheter was compared. RESULTS: The epidural pressure group(Group A) showed marked high epidural pressure(32.6+/-13.4mmHg) compared with those of intraventricular pressure, but in decompressive craniectomy group(Group B) shows nearly the same values(2.1+/-6.9mmHg). CONCLUSIONS: On the basis of the available comparison between these two methods of measuring intracranial pressure, in the light of the data we had established and the importance of ICP monitoring in neurosurgical critical care, intradural monitoring technique appears to be our measuring method of choice.

Hypothermia is considered a useful intervention for limiting pathophysiological changes after brain injury. Local hypothermia is a relatively safe and convenient intervention that circumvents many of the complications associated with systemic hypothermia. However, successful hypothermia treatment requires careful consideration of several factors including its practicality, feasibility, and associated risks. Here, we review the protective effects-and the cellular mechanisms that underlie them-of delayed and prolonged local hypothermia in rodent and canine brain injury models. The data show that the protective effects of therapeutic hypothermia, which mainly result from the modulation of inflammatory glial dynamics, are limited. We argue that decompressive craniectomy can be used to overcome the limitations of local brain hypothermia without causing histological abnormalities or other detrimental effects to the cooled area. Therefore, delayed and prolonged local brain hypothermia at the site of craniectomy is a promising intervention that may prove effective in the clinical setting.

OBJECTIVE: After a rigorous management of increased intracranial pressure by decompressive craniectomy (DC), cranioplasty (CP) is usually carried out for functional and cosmetic purposes. However, the optimal timing of CP remains controversial. Our study aims to analyze the relationship between the optimal timing of CP and the post-operative complications. METHODS: From January 2013 to December 2015, ninety patients who underwent CP in a single institution were analyzed. We set the independent variables as follows: 1) patient characteristics; 2) the time interval between the DC and CP; 3) operation time; 4) anesthesia time; and 5) pre-operative computed tomography (CT) findings such as a degree of sunken brain by ratio of A (the median length from scalp to midline) to B (the length from midline to inner table of skull at this level). The dependent variables of this study are the event of post-operative complications. RESULTS: The overall complication rate was 33.3%. There was no statistical significance in the time interval between the DC and CP in the groups with and without complications of CP (p=0.632). However, there was a significant statistical difference in the degree of sunken brain by ratio (A/B) between the two groups (p<0.001). CONCLUSION: From this study, we conclude that it is better to determine the optimal timing of CP by the pre-operative CT finding than by the time interval between the DC and CP. Hereby, we suggest a potentially useful determinant of optimal timing of CP.

Journal of Korean Neurosurgical Society 2006;40(3):193-195
Hydrocephalus is usually defined as the condition of ventricular dilatation due to the overproduction of cerebrospinal fluid(CSF) or dysfunction of absorption. The pattern of the CSF circulation may change after a cranioplasty secondary to previous decompressive craniectomy for refractory intracranial hypertension after head injury. The effect of the cranioplasty on CSF hydrodynamics has not been explored exactly. We report two cases of acute hydrocephalus developed after cranioplasty and discuss about the clinical importance with review of literatures.

OBJECTIVETo investigate the occurrence of posttraumatic hydrocephalus (PTH) in severe brain- injured patients who underwent decompressive craniectomy (DC) and to discuss the management.
METHODSA total of 389 patients suffering from severe head trauma between January 2004 and May 2010 were enrolled in this study. Clinical data were analyzed retrospectively. Of them, 149 patients who underwent DC were divided into two groups according to the presence of PTH: hydrocephalus group and nonhydrocephalus group. Clinical factors including preoperative Glasgow Coma Score (GCS), bilateral or unilateral decompression, and duraplasty in DC were assessed by single factor analysis to determine its relationship with the occurrence of PTH.
RESULTSOf the 149 patients undergoing DC, 25 (16.8%) developed PTH; while 23 developed PTH (9.6%) among the rest 240 patients without DC. Preoperative GCS, bilateral or unilateral decompression, duraplasty in DC were significantly associated with the development of PTH. Ventriculoperitoneal shunt was performed on 23 of 25 patients with PTH after DC. Frontal horn was preferred for the placement of the catheter. Sixteen of them were operated upon via frontal approach and 7 via occipital approach. After shunt surgery, both radiological and clinical improvements were confirmed in 19 patients. Radiological improvement was found in 2 patients. One patient died eventually of severe pneumonia. Shunt-related infection occurred in 1 patient, which led to the removal of the catheter.
CONCLUSIONSIt is demonstrated that the occurrence of PTH is high in patients with large decompressive skull defect. Patients with low GCS and bilateral decompression tend to develop PTH after DC. Duraplasty in DC might facilitate reducing the occurrence of PTH. Patients with PTH concomitant skull defect should be managed deliberately to restore the anatomical and physiological integrity so as to facilitate the neurological resuscitation.

Although decompressive craniectomy is an effective treatment for various situations of increased intracranial pressure, it may be accompanied by several complications. Paradoxical herniation is known as a rare complication of lumbar puncture in patients with decompressive craniectomy. A 38-year-old man underwent decompressive craniectomy for severe brain swelling. He remained neurologically stable for five weeks, but then showed mental deterioration right after a lumbar puncture which was performed to rule out meningitis. A brain computed tomographic scan revealed a marked midline shift. The patient responded to the Trendelenburg position and intravenous fluids, and he achieved full neurologic recovery after successive cranioplasty. The authors discuss the possible mechanism of this rare case with a review of the literature.

OBJECTIVE: Management guidelines for single intracranial hematomas have been established, but the optimal management of multiple hematomas has little known. We present bilateral traumatic supratentorial hematomas that each has enough volume to be evacuated and discuss how to operate effectively it in a single anesthesia. METHODS: In total, 203 patients underwent evacuation and/or decompressive craniectomies for acute intracranial hematomas over 5 years. Among them, only eight cases (3.9%) underwent operations for bilateral intracranial hematomas in a single session. Injury mechanism, initial Glasgow Coma Scale score, types of intracranial lesions, surgical methods, and Glasgow outcome scale were evaluated. RESULTS: The most common injury mechanism was a fall (four cases). The types of intracranial lesions were epidural hematoma (EDH)/intracerebral hematoma (ICH) in five, EDH/EDH in one, EDH/subdural hematoma (SDH) in one, and ICH/SDH in one. All cases except one had an EDH. The EDH was addressed first in all cases. Then, the evacuation of the ICH was performed through a small craniotomy or burr hole. All patients except one survived. CONCLUSION: Bilateral intracranial hematomas that should be removed in a single-session operation are rare. Epidural hematomas almost always occur in these cases and should be removed first to prevent the hematoma from growing during the surgery. Then, the other hematoma, contralateral to the EDH, can be evacuated with a small craniotomy.

Journal of Korean Neurosurgical Society 2006;40(1):51-53
Decompressive craniectomy is usually performed to relieve raised intracranial pressure(ICP) caused by various intracranial lesions. A 67-year-old man presented with acute subdural hematoma and traumatic intracerebral hematoma. The patient underwent a decompressive craniectomy. Four weeks later, the patient presented with acute neurological deterioration. Brain computed tomographic(CT) scans revealed the marked concavity of the brain at the site of the craniectomy and associated with midline shift which was reversed by cranioplasty. We report an unusual case of cerebral herniation from intracranial hypotension after decompressive craniectomy for a traumatic subdural hematoma. The cranioplasty may be helpful to prevent paradoxial cerebral herniation.
