Research summary
The study team hypothesise that patients with carotid stenosis or occlusions may be at higher risk of developing complications following cervical nerve root injections.
This is because carotid stenosis and occlusions lead to the development of new collateral arteries in the neck. Serious complications from cervical nerve root injections, such as haemorrhage and stroke are caused by inadvertent puncture of arteries close to the neural foramen.
Approaches to the neural foramen that theoretically minimise this risk have been described but are based on normal arterial anatomy.
The aim of this study will be to document the prevalence of arterial collateral vessels in relation to the neural foramen.
This will be a retrospective study of existing clinical radiology data: CT carotid angiograms. No new data will be acquired. There would be no intervention in the patients’ treatment. The study team consider this to be a low risk study.
