Aneurysm: A weak bulging area in the artery wall
Angiogram: A study showing arteries and veins by injecting contrast dye through a catheter and taking pictures using an X-ray
Angiography Suite: Operation theatre used for endovascular procedures
Arteriovenous malformations (AVM): A tangle of abnormal vessels connecting arteries and veins
Catheter: A thin flexible tube for insertion into a blood vessel through which devices can be introduced or contrast dye can be injected
Cerebral Angiogram: A study showing arteries and veins in the brain by injecting contrast through a catheter and taking pictures using x-ray
Coiling: Placing coils in an aneurysm to remove the aneurysm from circulation and prevent rupture
Coils: Small platinum coils used to occlude (fill) aneurysms. Coils are attached to a wire that is fed through a catheter and into the aneurysm
Craniotomy: Surgical procedure where a section of the skull is temporarily removed
Embolisation: Blockage of a blood vessel or aneurysm so blood can no longer flow through
Endovascular: Within the vascular system (arteries and veins)
Interventional Neuroradiologist (INR): A doctor specially trained to treat vascular diseases in the brain using minimally invasive endovascular techniques
Stent: A cylindrical device made of metal wire that is left ini the artery adjacent to a wide necked aneurysm to prevent coils from leaving the aneurysm
Stent assisted coiling: Using a stent i nthe artery adjacent to the aneurysm and placing coils in the aneurysm to exclude the aneurysm from circulation. The stent remains in the artery and the patient requires blood thinning medication to prevent clots
Subarachnoid Haemorrhage (SAH): Bleeding into the compartment surrounding the brain, often caused by the rupture of a brain aneurysm or AVM
Varicocoele: A varicocoele is a network bunch of enlarged veins in the scrotum
