Full blood examination and clotting profile (INR & APPT) are required for all patients. Thyroid function testing may be indicated and should be discussed with the radiologist. Pregnancy test should be performed in all women of reproductive age. Any relevant previous imaging tests should be available at the time of the first consultation. As a minimum there should be a recent MRI or CT. Other preliminary tests such as angiogram should be discussed with the interventional neuroradiologist.

The treating surgeon and the interventional neuroradiologist need to discuss the case before an appointment for embolisation can be made.

Please consult with the radiologist regarding the above.
Relative or absolute contraindications to iodinated contrast.
Any severe blood bleeding disorders need to have temporary control of the abnormal clotting profile. Consult haematology.
