No. Interventional neurology usually reaches the brain or spinal blood vessels through a catheter introduced into an artery or vein. It may avoid a large surgical opening in selected cases, but open surgery remains the better option for some patients.

No. Observation, microsurgical clipping, coiling, assisted coiling, flow diversion or an intrasaccular device may be considered. The recommendation depends on whether the aneurysm has ruptured, its size, shape and location, the vessels arising nearby and patient-specific risks.

Mechanical thrombectomy is considered for selected patients with acute ischaemic stroke caused by a treatable large-vessel blockage. Eligibility depends on time from symptom onset or last known well, imaging findings, the blocked vessel and the patient’s clinical condition.

Recovery varies widely. A planned diagnostic angiogram may require short observation, while treatment for a ruptured aneurysm or severe stroke may require intensive care and rehabilitation. The team will explain the expected course for the specific procedure.

Yes. Depending on the procedure, risks can include bleeding, vessel injury, contrast reaction, kidney injury, clot formation, stroke, infection or the need for additional treatment. Your specialist will discuss risks and alternatives before treatment whenever circumstances allow.
