Complications and consent following decompressive craniectomy: an illustrative case study.

PRIMARY OBJECTIVE: To assess clinical outcome following restoration of cranial contour in a young male who had suffered a severe traumatic brain injury. RESEARCH DESIGN: Case report. METHODS AND PROCEDURES: A young male was assessed before and after cranial reconstructive surgery with a custom-made titanium plate. The patient had previously required a bifrontal decompressive craniectomy in order to control intractable intracranial hypertension due to neurotrauma. Following an autologous cranioplasty he made very little neurological recovery and remained wheelchair-bound with severe contractures and was only able to follow single stage commands. Over the following 2 years he developed extensive resorption of his bone flap such that it required augmentation. MAIN OUTCOMES AND RESULTS: After surgery he clinically improved such that he was able to communicate more effectively and, although he remained severely disabled and fully dependent, he was able to communicate that he would have provided consent for the initial decompressive procedure even if he had known that the eventual outcome would be survival with severe disability and total dependence. CONCLUSIONS: Long-term follow-up is required for patients with severe traumatic brain injury not only to assess outcome and complications, but also to assess how acceptable that outcome is for the patient and their families.

Calidad de vida tras el tratamiento quirúrgico del infarto maligno de la arteria cerebral media / Quality of life following surgical treatment of malignant middle cerebral artery infarction

Introducción. Son escasas las publicaciones que valoran la capacidad de adaptación a la enfermedad de pacientes con infarto maligno de la arteria cerebral media sometidos a cirugía descompresiva. El propósito del trabajo es analizar la calidad de vida final y el grado de satisfacción de pacientes y familiares. Pacientes y métodos. Analizamos 21 pacientes al año de ser intervenidos. Para evaluar la calidad de vida, empleamos la versión española del Sickness Impact Profile. Para conocer el grado de satisfacción retrospectiva, preguntamos a familiares y pacientes si, conociendo las secuelas actuales del afectado, habrían estado igualmente de acuerdo con realizar la craniectomía descompresiva. Resultados. La esfera física se percibe como más perturbada que la relativa a aspectos emocionales. No existen diferencias en la calidad de vida entre pacientes con afectación del hemisferio derecho o izquierdo. Los pacientes con mejor situación funcional refieren una mejor calidad de vida. El 81% de los pacientes se encuentra satisfecho. Conclusión. A pesar de que todos los pacientes muestran una reducción en la calidad de vida después de la craniectomía descompresiva, la mayoría parecen satisfechos con el tratamiento recibido, incluso en afectación del hemisferio dominante o aquéllos con una discapacidad moderada-grave (AU)

Introduction. Little work has been published on the capacity to adapt to the disease of patients with malignant middle cerebral artery infarction who have undergone decompressive surgery. The purpose of this study is to analyse the final quality of life and the degree of satisfaction of patients and their relatives. Patients and methods. We analysed 21 patients one year after their operation. The quality of life was evaluated using the Spanish version of the Sickness Impact Profile. In order to determine the degree of retrospective satisfaction, we asked relatives and patients whether, now that the patient’s current sequelae are known, they would have still agreed to a decompressive craniectomy. Results. The physical sphere is felt to be more disrupted than that concerning emotional aspects. There are no differences in the quality of life between patients who have the right or the left hemisphere affected. Patients with a better functional situation report a better quality of life. Altogether, 81% of patients said they were satisfied. Conclusions. Despite the fact that all the patients show a loss of quality of life after a decompressive craniectomy, most of them seem to be satisfied with the treatment they have received, even in cases in which the dominant hemisphere is compromised or in those with a moderate-severe disability (AU)

[PEEK customized implant for skull esthetic reconstruction]. / Reconstruction esthétique de la voûte crânienne par implant sur mesure en PEEK.

INTRODUCTION: Craniotomies provide unsightly sequels. Conservative methods for the removed bone, autologous graft, or use of surgical cement do not always allow restoring cranial symmetry. A customized PolyEtherEtherKetone (PEEK) implant may then be used. This implant is made from 3D CT reconstruction. The PEEK material is biocompatible, conformable, strong enough to protect the brain. TECHNICAL NOTE: The authors report a case of aesthetic reconstruction of a large cranial defect using a customized PEEK implant. Balloon scalp expansion was performed before implant placement. DISCUSSION: The aesthetic results are satisfactory, the postoperative short and simple. PEEK is a good alternative to titanium implants for customized implants; it is easier to use and lighter. This customized implant is well suited to correct unsightly sequels of craniotomy.

Unexpected neuropsychological improvement after cranioplasty: a case series study.

OBJECTIVE: Decompressive craniectomy is often emergently performed in an effort to reduce intracranial hypertension. After this urgent intervention, brain-injured patients often start rehabilitation programs but are left with a skull defect. Cranioplasty is often performed in these situations in order to repair this defect, mainly for cosmetic reasons and/or the patient's safety. The possible effects of this breach on the patients' neurological recovery are poorly understood and have been scarcely evaluated until now. The effect of cranioplasty on cognitive and motor functions in severely brain-injured individuals remains controversial. METHODS AND PROCEDURES: In order to further support evidence of the beneficial effects of cranioplasty on motor and cognitive function in severely brain-injured individuals, we discuss four cases, retrospectively selected among a cohort of several patients who underwent decompressive craniectomy after severe brain injury. The selected patients presented a biphasic pattern of recovery of cognitive and motor performance consisting of an initial improvement, followed by a progressive worsening of neurological signs and symptoms, and, ultimately, an unexpected recovery of function following cranioplasty. MAIN OUTCOMES AND RESULTS: In all four cases, we found a deterioration of motor and neuropsychological deficits prior to cranioplasty and a subsequent unexpected improvement in performance on a neuropsychological battery and a series of motor function tests immediately after cranioplasty. CONCLUSIONS: Results give clear evidence that a subset of patients are negatively affected by the persistence of a breach in skull integrity during the rehabilitation phase of brain injury. Moreover, they show that the repair of the cranial defect can trigger relevant neurological improvement in both motor and cognitive domains. This possibility should serve as a reminder to rehabilitation clinicians to give serious consideration to prompt performance of cranioplasty during the time allotted for the rehabilitation of these patients.

Surgical strategies for neurological function preservation in severe brain contusion.

AIM: Traditional surgical strategies for severe brain contusion are constantly associated with variable degree of postoperative neurological dysfunction, which is in part attributed to the location and severity of contusion. The purpose of this study was to compare and evaluate these current surgical strategies, with an emphasis on neurological function preservation. MATERIAL AND METHODS: A retrospective review of surgical strategies employed for 142 cases of severe brain contusion was performed. The surgical strategies were stratified into four types, Type I, Simple DC, without resection of contusion; II, Resection of contusion, combined with DC; III, Safe cerebral lobe resection and DC, without resection of contusion; IV, Simple resection of contusion, without decompression. The patients were accordingly separated into four groups. RESULTS: The favorable prognosis rate in Group I, II and III was higher than Group IV on 6-month follow-up Glasgow Outcome Score (GOS). No significant difference of mortality rate was observed among Group I, II and III (p > 0.05), but the favorable prognosis rate of Group II was lower than Group I and III (p < 0.05). CONCLUSION: Simple DC and safe cerebral lobe resection combined with DC might achieve better therapeutic effect, and could be recommended as the preferred surgical strategies for severe brain contusion.

Detailed long-term outcome analysis after decompressive craniectomy for severe traumatic brain injury.

OBJECTIVE: To assess detailed long-term clinical outcome at least 1 year after decompressive craniectomy (DC) in patients with severe traumatic brain injury (TBI). METHODS: One hundred and thirty-one patients with severe TBI underwent DC between September 1997 and September 2005. Outcome was measured using the Glasgow Outcome Scale (GOS). Detailed outcome analysis was performed using Glasgow Outcome Scale Extended, Short-Form 36 (SF-36), Beck Depression Inventory, Trail Making Test B (TMT-B), Digit-Symbol Test (DST) and Barthel Index (BI). RESULTS: Sixty-three patients (48.1%) died during their initial hospital stay, 27 (20.6%) were discharged in a vegetative state, 32 (24.4%) with severe disability and nine (6.9%) with moderate disability (GOS 3 and 4, respectively). At time of follow-up 75 patients (67.7%) were either dead or in a vegetative state. Thirty patients with GOS >2 were recruited for a detailed outcome analysis: Major depression, neurologic deficits and impaired TMT-B and DST performances were common and significantly more prevalent than in normative controls. Yet, patients reported only modestly reduced SF-36 and high BI scores. CONCLUSIONS: Despite multiple health-related problems after DC, many patients proved highly functional in activities of daily living and reported qualities of life not significantly inferior to that of healthy individuals. Depression was common and requires to be addressed with patients and caregivers. Better targeted therapies could improve neuropsychological and psychiatric outcomes in this complex cohort.

Hemicraniectomy for malignant middle cerebral artery infarction: retrospective consent to decompressive surgery depends on functional long-term outcome.

BACKGROUND: Decompressive surgery for malignant middle cerebral artery infarction increases the number of surviving patients; this, however, leaves some patients severely disabled. This study analyzed the patients' retrospective consent to hemicraniectomy in light of the experienced functional outcome 12 months after hospital stay. METHODS: This retrospective study included all patients who underwent decompressive hemicraniectomy for malignant middle cerebral artery infarction in the Department of Neurology, University of Erlangen, Germany, from January 2006 until March 2009. Data on mortality and functional outcome (measured by the modified Rankin Scale; mRS) 6 and 12 months after treatment were correlated with retrospective consent to hemicraniectomy as well as with a quality of life instrument (EuroQol). Data were obtained by structured telephone interviews with the patients themselves or their closest relatives. RESULTS: In the study period 28 patients received decompressive surgery. Retrospective consent to hemicraniectomy was 82.1%. Five patients, or their closest relatives, would not agree to hemicraniectomy again, given their functional outcome after 1 year. Two out of two patients who experienced an mRS of 5 would not have consented. Low quality of life was most often declared in this subgroup. CONCLUSIONS: Retrospective consent to hemicraniectomy for treatment of malignant MCA infarction depends on functional long-term outcome. We need to identify those patients who would survive the malignant MCA infarction due to decompressive surgery but only reach a severely reduced functional status.

Decompressive craniectomy for patients with severe non-traumatic brain injury: a retrospective cohort study.

OBJECTIVE: To describe the current utilisation and outcomes for patients receiving decompressive craniectomy (DC) for acute non-trauma-related indications. DESIGN, SETTING AND PARTICIPANTS: Retrospective cohort study of neurosurgical patients who underwent DC to relieve acute intracranial hypertension after a non-traumarelated brain insult. The study was based on data from medical records of a tertiary referral neurosurgical intensive care unit over the period January 2001 to June 2008. MAIN OUTCOME MEASURES: Patient demographics, treatments received, indication for and result of DC, length of stay, hospital outcomes and 6-month outcomes. RESULTS: 54 patients underwent 56 DC procedures during the study period. The number of DCs performed per year increased over this period. Although intracranial pressure was significantly reduced by the procedure, 10 patients later died of uncontrollable intracranial hypertension. The patients had long hospital stays and consumed significant health care resources. Among survivors, about two-thirds had a good outcome, although it was rare for patients to be free of any deficit or complaint at follow-up. Complications were frequent, but not associated with high mortality. Overall 6-month mortality was 39%. CONCLUSIONS: DC has the potential to save lives, but also the potential to leave survivors in a severely debilitated state. The place of DC in managing patients with severe intracranial hypertension due to non-trauma related causes is yet to be definitively established.
