complications of decompressive craniectomy and how to avoid them. decompressive craniectomy in MCA infarct and Trauma
Dr. Shahnawaz Alam presents on decompressive craniectomy, including its history, indications, techniques, and clinical trials. Decompressive craniectomy is used to treat refractory intracranial hypertension by removing a portion of skull to allow brain swelling room. Common techniques include fronto-temporo-parietal craniectomy and bifrontal craniectomy. While clinical trials like DECRA and RESCUEicp show craniectomy reduces ICP, outcomes are often unfavorable with high mortality and disability rates. The role of decompressive craniectomy in traumatic brain injury remains controversial.
338 Indications and technique for cranial decompression after traumatic brain...Neurosurgery Vajira
This document discusses indications and techniques for cranial decompression after traumatic brain injury. It provides background on the history and advantages of decompressive craniectomy or craniectomy. Indications include elevated intracranial pressure refractory to medical management. Techniques involve large bone flap removal or lobectomy to reduce pressure. Complications can include hygromas, hydrocephalus, wound issues, bone flap resorption, and syndrome of the trephine. The goal is to reduce pressure and allow brain swelling space to prevent herniation.
1) Surgical management of traumatic brain injury involves evacuation of intracranial hematomas like epidural hematomas, acute subdural hematomas, intraparenchymal hemorrhages, and posterior fossa masses if they are larger than a certain size or causing neurological deterioration.
2) Preoperative evaluation and management focuses on optimizing factors like blood pressure, ICP, oxygenation. Craniotomies are performed to evacuate hematomas while controlling bleeding.
3) Potential complications include recurrent bleeding, brain swelling, and skull base fractures which are managed through techniques like hyperventilation, drainage of hematomas, and repair of fractures.
This document provides a summary of the history, indications, types, efficacy, complications and conclusions regarding decompressive craniectomy. Some key points:
- Decompressive craniectomy relieves increased intracranial pressure by removing a portion of skull bone and opening the dura, allowing swollen brain tissue to herniate out rather than compress the brainstem.
- Indications for decompressive craniectomy include severe traumatic brain injury, malignant middle cerebral artery infarction, aneurysmal subarachnoid hemorrhage, and other conditions causing refractory elevated intracranial pressure.
- Complications occur in 50-55% of cases and include CSF absorption disorders, expanding hematomas, syndrome

EAETV was found to significantly reduce ventricular size in acute hydrocephalus cases and decrease size in chronic cases, with minimal complications. Advantages of EAETV include avoiding restenosis risks and providing an alternative fenestration site. The presentation concludes that while preliminary EAETV results are encouraging, further studies are needed to evaluate its long-term efficacy.
Diffuse midline gliomas are rare and aggressive brain tumors that occur in midline structures like the brainstem, thalamus, or spinal cord. They mainly affect children and have a very poor prognosis, with median survival of 9-20 months. A defining characteristic is a mutation in the H3K27 gene. Treatment involves biopsy for diagnosis, followed by radiation and chemotherapy, but there is no standard chemotherapy regimen. Even with treatment, less than 10% of patients survive more than 2 years.
Trigeminal neuralgia is a condition characterized by severe, sporadic facial pain. It is most commonly caused by neurovascular compression of the trigeminal nerve by blood vessels at the root entry zone. Diagnosis involves assessing paroxysmal facial pain triggered by innocuous stimuli and ruled out other conditions. Treatment begins with medications like carbamazepine and oxcarbazepine, while microvascular decompression surgery provides the highest rates of long-term pain relief for refractory cases.

The 2021 WHO classification of CNS tumors builds on the 2016 edition by placing greater emphasis on molecular markers for both classification and grading. Some tumors are now entirely classified based on their molecular profile, while others remain primarily histologically assessed. A layered report structure will integrate histological, grading, and molecular information. Notable changes include raising IDH status and 1p19q codeletion to prominence for diffuse gliomas. Grading now occurs within each tumor type rather than equivalently across types. Molecular features can supersede histology in determining grade.

2. INTRODUCTION
• First described by Ernst von Bergmann first described the technique in 1880
• Annandale in 1894; Performed as palliative procedure for inoperable brain
tumor.
• Kocher(1901) first proposed DC as treatment of raised ICP.
• Cushing: Sub-temporal and suboccipital decompression.
3. • Decompressive craniectomy (DC) has been used as a final option in
the management of refractory intracranial hypertension/edema.
• Reduction of death and disability from traumatic brain injury (TBI) is
the goal of cranial decompressive surgery.
• Medically refractory cerebral edema is defined as ICP >20 mmHg
for >15 minutes in a given hour despite standard medical
interventions and external ventricular drainage.
• A method of “giving room to the swelling brain” and can be “ a
life-saving procedure.”
4. PATHOPHYSIOLOGY OF RAISED ICP
• ICP is pressure with in cranial vault, a
rigid structure with fixed volume.
• Contents of cranial vault:
– Brain parenchyma
– CSF
– Blood
Monro-Kellie Doctrine:
• Beyond compensatory mechanisms rise
in any of these, will increase ICP
exponentially
• ICP is one of the factors that govern
cerebral perfusion pressure.
5. FEED FORWARD CYCLE OF RAISED ICP
• Cranial vault compartmentalized by thick dural folds like falx, tentorium.
• Raised ICP leads to herniation across these compartments.
• Herniation distort vascular anatomy and CSF flow pathways leading to
further increase in ICP.
6. ROLE OF DC
• Increases buffering capacity of cranium.
• Allows outward herniation, preventing compression of brainstem
structures and reconstruct brain perfusion.
• ICP reduction vary from 15-85% depending on size of bone removed.
• Durotomy further decreases ICP.
AIMS OF DECOMPRESSIVE CRANIECTOMY
• Reduce ICP; Improve blood flow.
• Reduce damage to surrounding brain tissue i.e. reduce secondary brain
injury.
7. COMMON INDICATIONS OF DC
• Traumatic brain injury; Malignant cerebral infarction.
• Aneurysmal SAH; Others- Cerebral venous sinus thrombosis, Intracerebral
hematoma.
RECOMMENDATIONS FOR DECOMPRESSIVE CRANIECTOMY
• By American Association of Neurological Surgeons for patients with TBI and
refractory IH if some or all of the following criteria were met:
– Diffuse cerebral swelling on cranial CT imaging
– Within 48 hours of injury
– No episodes of sustained ICP > 40 mmHg before surgery
– GCS >3 at some point subsequent to injury
– Secondary clinical deterioration
– Evolving cerebral herniation syndrome
– Pupillary abnormalities but respond to mannitol
(Guidelines for the Management of Severe Traumatic Brain Injury- 4th Edition Brain Trauma Foundation)
8. TYPES OF DC
Primary/Prophylactic DC
• Any surgical decompression performed, with or without brain tissue
removal, in patients undergoing surgery primarily for the evacuation of any
type of intra-dural lesion.
• Aim: not to control refractory ICP but to avoid increase in ICP.
• Decision taken based on CT, not on ICP.
Secondary/Therapeutic DC
• Continuous ICP monitoring is conducted.
• DC performed when ICP is refractory to medical treatment.
9. RECOMMENDATION OF BRAIN TRAUMA FOUNDATION
• General maneuvers
– head elevation & neutral position (to avoid venous congestion)
– Normothermia (36.5-37.5 F)
– sedation
– volume resuscitation
• First line therapy: CSF drainage, hypocapnia (PaCO2 30-35mmHg), mannitol
administration.
• Second tier: high dose barbiturates, intense hyperventilation (PaCO2-
<30mmHg), increase in MAP, mild to moderate hypothermia, decompressive
craniectomy.
• Inadequate craniectomy size is associated with parenchymal hemorrhage-
infarction and increased mortality.
(Wagner S et al. Journal of Neurosurgery, May 2001, vol./is. 94/5(693-6)
10. • TBI: most common indication for DC; Pathophysiology of TBI: Primary injury Vs
Secondary injury.
• Secondary injury is amenable to treatment. Aim of the treatment is to prevent
secondary injury.
13. FTP APPROACH
• A large reverse question mark incision is
made starting at the level of the zygoma and
curving posteriorly above the ear, over the
parietooccipital region, then superiorly and
anteriorly, approximately 2 cm lateral to the
midline, and stopping just behind the hairline.
• The posterior extent of the incision should be
more than 15 cm behind the keyhole to allow
for an adequate craniectomy flap.
• Medially, the craniectomy should extend to
only about 2 to 3 cm from the midline to
prevent damage to any draining veins and
arachnoid granulations near the superior sagittal
sinus.
14. • The temporalis dissection should be carried down to the zygoma to adequately
expose the temporal bone and maximize the temporal decompression.
• Preferences for the location and number of burr holes vary, but typically three
burr holes are made: one at the keyhole, one more inferiorly in the temporal
bone and posterior to the sphenoid bone, and one supero-posteriorly in the
parietal bone.
• Large FTP DC (standard trauma
craniectomy-12x15cm2) significantly
improved the outcome in severe TBI
patients with refractory intracranial
hypertension, compared with routine
temporoparietal craniectomy (6x8cm2),
and had a better effect in terms of
decreasing ICP.
• Small size craniectomies associated
with pericraniectomy hemorrhage and
infarct (diameter < 8 cm).
15. • A suboptimal DC will lead to exacerbated external brain herniation and shear
forces at the bone edges, which can cause intraparenchymal hemorrhage and
kinking of the cerebral veins.
• Durotomy enhances further decrease in ICP; Durotomy with augmentative
duraplasty recommended.
• Only durotomy without duraplasty; increase risk of herniation of parenchyma;
epilepsy; CSF leak.
16. In a decompressive hemicraniectomy, the dural opening is just as important as the craniectomy.
Hemostasis should be obtained prior to dural opening (A), and the dura should be opened in a stellate
fashion to maximize cerebral decompression (B and C). The dura can be left open and the dural flaps laid
over a dural substitute prior to skin closure (D).
17. BIFRONTAL CRANIECTOMY
• In contrast to DHC, the bifrontal
craniectomy used in situations of bifrontal
contusions or diffuse cerebral edema.
• An incision is made beginning at the level of
the zygomatic arch just anterior to the tragus
on one side, coursing back 2 to 3 cm behind
the coronal suture, and down the
contralateral zygomatic arch.
• The myocutaneous flap is then brought
forward over the orbital rim. Care should be
taken to dissect out the supraorbital nerves
from the supraorbital notch on either side.
• A series of symmetric burr holes are then made in the bilateral keyholes,
bilateral squamous portions of the temporal bone, and straddling the
superior sagittal sinus just posterior to the coronal suture. Some authors
advocate drilling burr holes adjacent to the anterior most portion of the superior
sagittal sinus as well.
18. • The superior sagittal sinus can be dissected away from the overlying bone by
passing a Penfield 3 between the posterior and anterior burr holes. The burr holes
are then connected with a cutting drill bit and footplate, making sure to cross the
superior sagittal sinus last.
• Once the bone flap is elevated, bleeding from the superior sagittal sinus can be
controlled with strips of Gelfoam. The temporal portion of the craniectomy is
then extended downward to the floor of the middle fossa.
• The key to opening the dura with a bifrontal craniectomy is to divide the
anterior portion of the superior sagittal sinus and underlying falx. Without
this step, the brain is not free to expand and can be damaged by herniation
against a tight dural edge.
19. • As with DHC, the dural opening must be wide. It begins at the floor of the
middle fossa and courses anteriorly along the course of the craniectomy, spanning
the entire anterior width of the craniectomy and crossing the anterior portion of
the superior sagittal suture to reach the contralateral middle fossa floor.
• The dural opening should then also be taken from the middle fossa floor
posteriorly to within approximately 2 cm of the posterior portion of the
superior sagittal sinus on either side.
• To cross the anterior superior sagittal sinus, two heavy sutures are passed around
the sinus and tied to occlude it. The sinus is then divided with scissors. The
underlying falx should then be divided, with care taken to avoid the bilateral
anterior cerebral arteries.
20. • Polin technique bifrontal craniectomy
– anteriorly roof of orbit; posteriorly
3-5 cm behind coronal suture
– base of temporal bone
– Saggital sinus ligation and division
Subtemporal decompression: area 26-33 cm3
• decreases ICP; unable to improve blood flow
• temporal lobe herniation and necrosis
23. Syndrome of the Trephined
• Overall prevalence of 10%; initially described by Grant and Norcross in 1939.
• The sinking of the scalp due to lack of bony support causes cerebral blood flow
anomaly and dysfunction in the underlying cortex due to impaired CSF flow
dynamics.
• Most common symptoms: motor weakness (61.1%) followed by cognitive
deficits (44.4%), language deficits (29.6%), altered level of consciousness
(27.8%), headache (20.4%), psychosomatic disturbances (18.5%), seizures or
electroencephalographic changes (11.1%), and cranial nerve deficits (5.6%).
• It manifests either as new symptoms causing deterioration of the patient
condition or as failure to retain the early gains. It could manifest as early as 3
days to as late as 7 years (with an average of 5 months).
• These symptoms, as well as, cerebral blood flow abnormalities improve
dramatically after a cranioplasty. Yang has suggested it is safe to do early
cranioplasty within 5-8 weeks to mitigate this risk.

• Multicenter, randomized, controlled trial to test the efficacy of bi-fronto-
temporo-parietal DC in adults under the age of 60 years with TBI in whom
first-tier intensive care and neurosurgical therapies had not maintained
intracranial pressure below accepted targets; Dec 2002- April 2010; 15
tertiary care centres in Australia, New Zealand, Saudi Arabia.

• Results compared based on extended Glasgow outcome scale at 6 months
27. RESULTS
Conclusion
In adults with severe diffuse
traumatic brain injury and
refractory IH , early bi-fronto-
temporo-parietal DC decreased
ICP and the length of stay in the
ICU but was associated with
more unfavourable outcomes.
28. RESCUEicp TRIAL

– Vegetative state: 8.5% versus 2.1%
– Lower severe disability (dependent on others for care): 21.9% versus
14.4%
– Upper severe disability (independent at home): 15.4% versus 8.0%
– Moderate disability: 23.4% versus 19.7%
– Good recovery: 4.0% versus 6.9%
• Favorable outcomes (upper severe disability or better on the GOS-E) at 6
months: 42.8% versus 34.6% (P = 0.12).
32. SECONDARY OUTCOMES
• GOS-E distributions at 12 months
– Death:30.4% versus 52.0%
– Vegetative state: 6.2% versus 1.7%
– Lower severe disability: 18.0% versus 14.0%

45.4% versus 32.4% of those in the medical group (P=0.01)
• Median time to discharge among survivors: 15.0 days vs. 20.8 days
(P=0.01)
• Control of ICP: Better in surgical group than in the medical group.
33. ADVERSE EVENTS & CRITICISMS
Adverse event
• 16.3% vs. 9.2% (P=0.03); Most commonly pneumonia, SSI, postoperative
hematoma
Criticism
• Recruitment was slow, taking over 10 years. Half of centers recruited 3 or
fewer patients.
• Clinical teams who cared for the patients were aware of trial group
assignments, although this was mitigated by outcome adjudication.
• A large proportion of patients in the medical group underwent
decompressive craniectomy (37%)
34. DECRA vs RESCUEicp
• DECRA and RESCUEicp are higher quality studies whose
findings supersede those of lesser quality investigations.
• Though both studied secondary DC for the treatment of
refractory ICP elevation, a key difference in the study
protocols for DECRA and RESCUEicp is that they were
designed to investigate conditions
of early and late refractory ICP elevations, respectively.
• Indeed, DECRA enrolled TBI patients with ICP above 20 mm
Hg for 15 min over a 1-h period despite the optimization of
tier 1 treatments within the first 72 h of care (early), while
RESCUEicp enrolled patients with ICP greater than 25 mm
Hg for 1 to 12 h refractory to 2 tiers of treatment within 10
d of admission (late).
36. PRESENT STATUS OF DC IN TBI
• Pediatric population: DC reduces risk of death and unfavorable outcome.
• For adults: Role of DC in raised ICP due to TBI as second tier treatment is
still controversial.
• Early DC reduces brain edema formation by more than 50% and prevents
secondary brain damage when performed early enough (i.e., during the
first 3 h after trauma).
• Malignant Cerebral Infarction: Large territorial parenchymal infarction
with post ischemic edema and associated with uncal or axial herniation;
Occlusion of proximal MCA, more than 50% of supplied territory involved.
• Treatment: medical management or surgery (DC); DC clearly reduce
mortality however survivors suffered high morbidity .
37. • Malignant MCA Infarction: An infarction of at least two thirds MCA
territory upward; Present clinically with severe hemispheric stroke
syndrome and progressive deterioration of consciousness within the first 2
days.
• Thereafter, symptoms of transtentorial herniation occur within 2-4 days of
stroke onset; Prognosis is poor and mortality is as high as 80%.
• Very high mortality despite maximal medical treatment: 70% (37/ 53 )
died in NICU (33/37 died within first 5 days); 78% (35/45) died within 1
week
• 3 RCTs conducted and results published:
DECIMAL (DEcompressive Craniectomy In MALignant middle cerebral artery
infarction)
DESTINY (DEcompressive Surgery for Treatment of INfarction of malignant
middle cerebral arterY)
HAMLET ( Hemicraniectomy After Middle cerebral artery infarction with Life -
threatening Edema Trial )
38. POOLED ANALYSIS
Results:
• Only patient underwent decompression with in 48 hrs were considered for pooled
analysis; n=109, Surgery-58, Medical-51.
• Effect on mortality:
DECIMAL: absolute reduction in risk 53% at 6 months.
DESTINY: 12% mortality in surgical and 53% in medical group at 30 days.
HAMLET: 38% reduction in risk at 1 year.
39. • Effect on mortality: all 3 trial shows significant reduction in mortality;
Absolute reduction in mortality is 49.9%.
• Effect on severe disability (mRS score 5): absolute reduction in risk of
bad functional outcome was 41.9%.
• Conclusion: surgical decompression with in 48 hrs of onset of stroke
reduced risk of significant morbidity.
• Disability in survivors: while demonstrating an undeniable increase in
the number of survivors among surgical patients, also showed an
increase in the number of survivors with moderately severe disability
(mRS score of 4).
• Pooled analysis of all 3 trials provides Class I evidence for the
performance of early decompressive craniectomy in the setting of large
unilateral infarcts (volume > 145 cc) within 48 hours of the ischemic
event.
40. Current algorithm for use of
DC
The only Class I data (recently
published from the DECRA trial)
suggest that primary DC may
increase morbidity with equal
chance of survival compared to
medical management.
The current standard practice of
performing secondary DC (red
arrow) is up to the discretion of
the treating neurosurgeon
(though the results of the
RESCUEicp trial may provide
Class I evidence for this
management decision in the
future).
