Abstract:
Traumatic extradural haematoma (EDH) complicates 1-4% of all head injuries and is a major factor contributing to morbidity and mortality. Clinical awareness and early diagnosis are the keys to successful management. With the advent of computerised tomographic (CT) scanning a trend towards 'zero mortality' has been reported. We report four adolescent cases presenting with mild head injury (Glascow Coma Score 13-15) who subsequently died as a result of EDH. We suggest that excessive delay both in recognising the condition and the subsequent referral and transfer are factors contributing to the mortality of these patients.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
