Decompressive Craniotomy/SDH/EDH/ICH
Decompressive Craniotomy is an emergency or urgent neurosurgical procedure performed to evacuate life-threatening blood clots — subdural, epidural, or intracerebral haematomas — from within the skull, immediately relieving pressure on the brain and preventing permanent neurological damage or death.
Overview
Decompressive Craniotomy for SDH, EDH, or ICH involves removing a section of the skull bone to directly access and evacuate a life-threatening intracranial haematoma — a collection of blood that is compressing the brain and causing herniation. Subdural haematomas (SDH) form between the dura and the brain surface, epidural haematomas (EDH) form between the skull and the dura, and intracerebral haematomas (ICH) occur within the brain parenchyma itself. In each case, the rapidly accumulating blood mass raises intracranial pressure to life-threatening levels, and urgent surgical decompression can be the difference between life and death or between full recovery and permanent disability.
Types of Craniotomy for Haematoma Evacuation
The surgical approach to craniotomy for haematoma evacuation is determined by the type, location, and volume of the haematoma and the urgency of the clinical situation.
- Craniotomy for Acute Subdural Haematoma (emergency evacuation of arterial or venous SDH)
- Burr Hole Drainage for Chronic Subdural Haematoma (less invasive drainage for liquefied chronic SDH)
- Craniotomy for Epidural Haematoma (urgent evacuation of arterial EDH — highly time-sensitive)
- Craniotomy for Spontaneous Intracerebral Haematoma (for large, accessible, or deteriorating ICH)
- Decompressive Craniectomy without Bone Replacement (for severe brain swelling requiring prolonged decompression)
Risk Factors for Intracranial Haematoma
Intracranial haematomas occur in specific clinical contexts and in patients with identifiable risk factors. Early recognition of these risk factors improves preparedness and outcome.
- Head trauma from road traffic accidents, falls, or assaults — the most common cause
- Anticoagulant or antiplatelet medication use dramatically increasing haematoma risk
- Hypertension causing rupture of small perforating blood vessels producing ICH
- Cerebral arteriovenous malformation or aneurysm rupture
- Coagulopathy from liver disease, haematological disorders, or medication
- Cerebral venous sinus thrombosis causing venous haemorrhagic infarction
Intracranial Haematoma Symptoms
The symptoms of intracranial haematoma are potentially life-threatening and require immediate emergency neurosurgical evaluation without delay.
- Sudden severe headache — the most severe headache of the patient's life
- Rapid deterioration in consciousness or GCS score
- Unequal pupils or fixed, dilated pupil indicating herniation
- Focal neurological deficits — weakness, speech difficulty, or visual loss
- Seizures following head trauma or spontaneous onset
- Nausea, vomiting, and progressive drowsiness
- Brief lucid interval followed by rapid deterioration (classic EDH presentation)
- Confusion, personality change, or subtle cognitive decline in chronic SDH

Clinical Features
The technology, techniques and clinical approach behind our decompressive craniotomy/sdh/edh/ich.
Emergency theatre mobilisation for immediate haematoma evacuation within the critical window
Intraoperative microscope provides precision for bleeding source identification and sealing
Bipolar coagulation and haemostatic agents used throughout for thorough surgical haemostasis
Immediate post-operative CT confirms complete haematoma evacuation
Neurosurgical ICU with ICP monitoring and specialist nursing for post-operative care
Preparation Instructions
- Obtain an urgent CT head without delay — this is the most critical investigation before surgery
- Blood tests including CBC, coagulation, blood group and crossmatch are drawn simultaneously
- Reverse anticoagulation urgently using vitamin K, FFP, or specific reversal agents as directed
- Establish intravenous access, airway protection, and haemodynamic monitoring immediately
- This is often an emergency procedure — fasting cannot always be achieved before surgery
- Obtain consent from the patient if conscious or next-of-kin in cases of impaired consciousness
- Mannitol and hyperventilation may be used as temporary ICP management measures before theatre
- Confirm neurosurgical ICU availability before proceeding to emergency surgery
The Procedure
Step-by-step guide to what you can expect during your decompressive craniotomy/sdh/edh/ich procedure.
Emergency CT Assessment and Decision
Your neurosurgeon immediately reviews the CT head scan to confirm the haematoma type, location, and volume — making the critical decision to proceed with urgent surgical evacuation before irreversible brain damage from raised pressure occurs.
Emergency Theatre Mobilisation
The operating theatre team mobilises rapidly — preparing instruments, microscope, and haemostatic agents while anaesthesia establishes airway control and reverses anticoagulation as quickly as possible.
Craniotomy Bone Flap Removal
A series of burr holes are connected to create a bone flap directly over the haematoma under fluoroscopic confirmation. The bone is elevated and the dura is assessed for tension before it is carefully opened.
Haematoma Evacuation Under Microscope
The haematoma is evacuated using careful suction, saline irrigation, and bipolar coagulation of all bleeding points. Your neurosurgeon works methodically to remove all clot while permanently sealing the source of bleeding.
Bone Replacement or Decompression Decision
After evacuation and confirmed haemostasis, the bone flap is replaced and secured with titanium plates — or deliberately left out if significant brain swelling is present and ongoing decompression is required.
ICU Transfer and Neurological Recovery
You are transferred to the neurosurgical ICU for continuous monitoring, neurological observations, and repeat CT imaging to confirm complete haematoma evacuation and guide early rehabilitation planning.
What to Expect
Decompressive Craniotomy is performed under general anaesthesia and takes 2 to 3 hours. A scalp incision is made over the haematoma site, a bone flap is removed, the dura is opened, and the haematoma is carefully evacuated under direct vision or using suction — immediately relieving the pressure on the brain. The bone is replaced and secured or left out temporarily if significant brain swelling is present. You will be monitored in the neurosurgical ICU for 24 to 72 hours post-operatively with continuous neurological and ICP monitoring.
Recovery
After Decompressive Craniotomy, neurological rehabilitation begins as early as physiologically possible — every day of early rehabilitation makes a significant difference to long-term functional recovery. Take all prescribed medications including anti-epileptic drugs without interruption and never stop these without medical advice. Attend all follow-up CT scans and neurosurgical reviews at the scheduled intervals to monitor brain recovery and any residual haematoma. Contact your neurosurgical team immediately for new neurological deterioration, seizures, fever, wound changes, or increasing headache.
