A series of radiographs are taken as the contrast agent spreads through the brain's arterial system, then a second series as it reaches the venous system. For some applications, [citation needed] cerebral angiography may yield better images than less invasive methods such as computed tomography angiography and magnetic resonance angiography. In ...
Endovascular coiling is an endovascular treatment for intracranial aneurysms and bleeding throughout the body. The procedure reduces blood circulation to the aneurysm through the use of microsurgical detachable platinum wires, with the clinician inserting one or more into the aneurysm until it is determined that blood flow is no longer occurring within the space.
Pneumoencephalography was associated with a wide range of side effects, including headaches and severe vomiting, often lasting well past the procedure. [2] During the study, the patient's entire body would be rotated into different positions in order to allow air to displace the CSF in different areas of the ventricular system and around the brain.
Depending on the type of angiogram, access to the blood vessels is gained most commonly through the femoral artery, to look at the left side of the heart and at the arterial system; or the jugular or femoral vein, to look at the right side of the heart and at the venous system.
Angiogram: a test that looks at the blood vessels that feed the brain. An angiogram will show whether the blood vessel is blocked by a clot, the blood vessel is narrowed, or if there is an abnormality of a blood vessel known as an aneurysm.

Pins and needles/burning sensation, nausea and temporary discomfort are possible sensations during CO 2 angiography, mainly because the transient ischemia caused by the CO 2 bubbles flowing in the bloodstream. CO 2 is also neurotoxic, so brain injections should be avoided. The most feared complication for intravascular use is air embolism ...
Interventional neuroradiology (INR) also known as neurointerventional surgery (NIS), endovascular therapy (EVT), endovascular neurosurgery, and interventional neurology is a medical subspecialty of neurosurgery, neuroradiology, intervention radiology and neurology specializing in minimally invasive image-based technologies and procedures used in diagnosis and treatment of diseases of the head ...
