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.
The smaller the aneurysm the better the prognosis. There is less risk for ischemic myocardial damage and mortality with smaller aneurysms. Aneurysms with an internal diameter > 8 mm have poorer outcomes, since these aneurysms can be occluded and be associated with complications such as arrhythmias , myocardial infarction , or sudden death.
Clipping requires a craniotomy (opening of the skull) to locate the aneurysm, followed by the placement of clips around the neck of the aneurysm. Coiling is performed through the large blood vessels (endovascularly): a catheter is inserted into the femoral artery in the groin and advanced through the aorta to the arteries (both carotid arteries ...
Clipping is a surgical procedure performed to treat an aneurysm. If the aneurysm is intracranial, a craniotomy is performed, and afterwards an Elgiloy (Phynox) or titanium Sugita clip is affixed around the aneurysm's neck. Surgical clipping was introduced by Walter Dandy of the Johns Hopkins Hospital in 1937.
An aneurysm is an outward bulging, likened to a bubble or balloon, caused by a localized, abnormal, weak spot on a blood vessel wall. [1] Aneurysms may be a result of a hereditary condition or an acquired disease. Aneurysms can also be a nidus (starting point) for clot formation and embolization.
The degree of aneurysm occlusion is graded on a five-point scale from 0 (no change in the endoaneurysmal flow) to 4 (complete obliteration of the aneurysm). The patency status of the parent artery is evaluated on a three-point scale, from no change in the parent artery diameter to parent artery occlusion. This grading system is used in clinical ...

These inflammation and thrombis can caused by infective endocarditis, artificial heart valve or other heart problems. Similar to vasculitis, rupture of mycotic aneurysm also causes SAH in cerebral sulci, mostly located in the vertex. If mycotic aneurysm is located more proximally, it will produce diffuse SAH pattern.
