OBJECTIVE We evaluated the use of MDCT in the diagnosis and management of lower gastrointestinal bleeding (hematochezia). CONCLUSION MDCT is proposed as an alternative first-line investigation to locate lower gastrointestinal bleeding before placing the patient under observation or performing embolization or surgery.
BACKGROUND A transorbital intracranial injury with a wooden foreign body can be very difficult to diagnose and manage. The orbit forms an easy path for low-velocity foreign bodies into the intracranial space. The severity of the injury is often masked by unobtrusive superficial wounds. Computed tomography (CT) findings may be misinterpreted as… (More)
Spontaneous bilateral carotid and vertebral artery dissections (CADs and VADs) are rare. A 29-year-old female presented with a collapse, 4 weeks after a sudden onset of severe neck and shoulder pain. CT scan revealed diffuse subarachnoid hemorrhage (SAH) and early hydrocephalus. Angiography revealed bilateral CADs and VADs, along with multiple fusiform and… (More)
OBJECTIVE To investigate whether the location and extent of the CT hyperdense artery sign (HAS) at presentation affects response to IV alteplase in the randomized controlled Third International Stroke Trial (IST-3). METHODS All prerandomization and follow-up (24-48 hours) CT brain scans in IST-3 were assessed for HAS presence, location, and extent by… (More)
A young man with Fisher grade IV subarachnoid haemorrhage (SAH) underwent aneurysm coiling following external ventriculostomy. Coiling was complicated by thrombus formation and parent vessel occlusion necessitating anti-platelet therapy. Several hours after anti-platelet therapy, catastrophic haemorrhage associated with the ventriculostomy tract occurred.… (More)
Numerous simulators have been developed for the training of surgeons concerning many surgical procedures. In many cases, the simulators are both demanding of space and are costly. We have designed a low cost versatile simulator that can be used almost anywhere on most computer systems.
BACKGROUND AND PURPOSE Endovascular treatments have the potential to accelerate reperfusion in acute ischaemic stroke with large vessel occlusion. In the UK only a few stroke centres offer this interventional option. The University Hospital of North Staffordshire (UHNS) has treated the largest number of cases in the UK. Results of the first 106 endovascular… (More)
Recurrent posterior circulation infarcts frequently involve multiple vascular territories, suggesting an embolic source. We describe a patient with left vertebral artery occlusion who had recurrent transient ischaemic attacks due to cerebral embolization originating from the occluded vertebral artery in spite of optimal anticoagulant and antithrombotic… (More)
Spontaneous carotid artery dissection is a rare condition with potentially devastating consequences. Internal carotid artery and vertebral artery dissections have been implicated as the cause of 20% of strokes occurring in patients younger than 45 years. We describe a very rare case of a nontraumatic common carotid artery dissection in a 45-year-old man… (More)
