Supratentorial Epidural Hematoma after Posterior Fossa Surgery

Supratentorial Epidural Hematoma after Posterior Fossa Surgery

Non-traumatic, non-arterial origin delayed Epidural Hematoma after posterior fossa surgery is extremely rare. Moreover, the pathogenesis of its supratentorial extension is obscure.

The possible causes include sudden decompression of ventricular pressure in the supratentorial compartment, rupture of cortical veins in the sitting positioncoagulopathy, hemodynamic fluctuations during surgery, and position-related ischemia 1).

The lowering of the ventricular pressure by the ventricular tapduring the operation may play significant role in the formation of the extradural hematoma.

The younger age of the cases and the long history of increased intracranial pressure were stressed in the literature2).

Wolfsberger et al., stressed the importance of early postoperative CT scan and optimal management of ventricular pressure and coagulation status to detect and prevent this possibly life-threatening complication 3).

Avci et al., from Mersin, reported a case during removal of a huge Posterior fossa dermoid cyst 4).

Pandey et al., from Bangalore reported in 2008 a large bifrontal extradural hematoma following posterior fossa surgery for a vermian medulloblastoma5).

Tsugane et al., reported five cases of the supratentorial extradural hematomas secondary to the posterior fossa craniectomy.

The site of the hematoma was far from the operative field and two cases showed acute course and three were rather mild. The symptoms of this complication were the unsuspected sensorium disturbance, anisocoria and the non-functioning ventricular drainage. Two cases died of this complication and two were severely disabled 6).

Multiple Supratentorial Epidural Hematomas

Tyagi et al., from Bangalore published Multiple Remote Sequential Supratentorial Epidural Hematoma7).

Wolfsberger et al., from Vienna published a 31-year-old female who presented with a history of chronic hydrocephalus due to fourth-ventricular plexus papilloma. Following resection of the posterior fossa tumor with intraoperative placement of a ventricular drainage, she consecutively developed four supratentorial epidural haematomas at different locations, all necessitating evacuation. The clinical manifestations ranged from subtle neurological deficits to signs of tentorial herniation; the ultimate outcome was complete recovery. Rapid tapering of CSF pressure after long-standing hydrocephalus and clotting disorders could be implicated as causative factors. They stressed the importance of early postoperative CT scan and optimal management of ventricular pressure and coagulation status to detect and prevent this possibly life-threatening complication 8).

Temporal epidural hematoma surgical technique

Temporal epidural hematoma surgical technique

Surgical safety checklist

Preoperative antibiotic prophylaxis

Skin Preparation

Positioning

The supine position is used with the patient‘s head rotated for temporal access. Extremes of head rotation can obstruct the jugular venous drainage, and a shoulder roll can combat this problem or lateral positioning (park bench position).

Skin incision

Craniotomy

Technical issues

1. clot removal: lowers ICP and eliminates focal mass effect. Blood is usually thick coagulum, thus exposure must provide access to most of clot. Craniotomy permits more complete evacuation of hematoma than e.g. burr holes.

2. hemostasis:coagulate bleeding soft tissue (dural veins & arteries). Apply bone wax to intradiploic bleeders (e.g. middle meningeal artery). Also requires large exposure

3. prevent reaccumulation: (some bleeding may recur, and dura is now detached from inner table) place dural tack-up sutures to edges of craniotomy and use central “tenting” suture.

Clinical features

Because of the non-specific symptoms and the potential for rapid and fatal deterioration of Posterior fossa epidural hematoma in children, an early computed tomography (CT) scanning is necessary for all suspicious cases.

In nine cases.The clinical picture was dominated by headache, vomiting, and gait ataxia. An occipital fracture was seen in 77.7% of the patients. In all cases, the diagnosis was made by computed tomography. 1).

Treatment

see Review and Management Guidelines 2).

Although some patients have been successfully treated with conservative approach, most studies support timely management of posterior fossa epidural hematoma by surgical intervention in children.

The absence of an occipital skull fracture or the presence of normal pulse rate and blood pressure should not influence the decision. Lumbar puncture is absolutely contraindicated 3).

Little evidence is available regarding the feasibility of using trephination mini-craniectomy for traumatic PFEDH in children 4).

Outcome

The overall prognosis normally is excellent 5) 6) 7).

Torrential venous bleeding can be a major problem due to rupture of the adjacent sinuses. Timely intervention is crucial for achieving good outcome, keeping in view a low threshold for surgical evacuation 8).
