Epidural haematoma after a combined spinal-epidural anaesthetic in a patient treated with clopidogrel and dalteparin.

We report a case of a spinal-epidural haematoma occurring in a patient after a combined spinal-epidural anaesthetic. She had been taking clopidogrel and had received perioperative dalteparin for thromboprophylaxis. Despite adhering to standard guidelines concerning administration of low molecular weight heparin perioperatively and stopping the clopidogrel 7 days before the anaesthetic, the patient developed an epidural haematoma.

The role of MRI in the diagnosis of MS.

Magnetic resonance imaging (MRI) is the most widely used imaging technique in the investigation of multiple sclerosis (MS). Although MS remains a clinical diagnosis, MRI has become an invaluable tool in understanding and monitoring the disease, and is commonly used to confirm the clinical diagnosis. Various imaging techniques can be used but T2-weighted brain imaging remains the standard tool. The officially endorsed imaging criteria for MS places greater emphasis on the spatial and temporal distribution of lesions than on their individual appearance. This review focuses on the more typical findings in MS, and considers the current role of MRI in the diagnosis.
