Subarachnoid haemorrhage from carotid siphon and bifurcation - what does this mean
Subarachnoid haemorrhage from carotid siphon and bifurcation is a type of stroke caused by a rupture of a blood vessel in the brain. it occurs when a weakened blood vessel in the carotid siphon or bifurcation area of the brain ruptures, causing bleeding into the subarachnoid space. this can lead to a sudden onset of severe headache, confusion, and neurological deficits.
What happens during the disease - subarachnoid haemorrhage from carotid siphon and bifurcation
Subarachnoid haemorrhage from carotid siphon and bifurcation is caused by a rupture of a saccular aneurysm in the carotid siphon and bifurcation. this rupture causes blood to leak into the subarachnoid space, leading to an accumulation of blood, which can cause a range of symptoms such as severe headache, nausea, vomiting, and neurological deficits. if left untreated, the condition can be fatal.
How does a doctor diagnose
- CT scan of the brain
- Angiography of the carotid siphon and bifurcation
- MRI of the brain
- Cerebral angiography
- Lumbar puncture
- Ultrasound of the neck
- Doppler ultrasound of the neck
Additional measures may include:
- Blood tests
- EEG
- Nerve conduction studies
