How long does cerebral angiography take to recover

Cerebral angiography is an examination, not a treatment. Generally, MRI or CT is performed on the patient to find vascular lesions, such as vascular stenosis or vascular malformation, which need to be further clarified. If the patient agrees, there are surgeons in the intervention room who insert a tube into the skull through the radial artery or femoral artery to inject contrast medium, and further develop the intracranial blood vessels. If the patient does not need further treatment, the tube (which is the guidewire) can be removed, pressure applied to stop bleeding and the patient returned to the ward. After returning to the ward, lie flat for 12 hours and then be able to get out of bed.
