Cerebral bypass surgery was developed in the 1960s in Switzerland by Gazi Yaşargil. When a patient has an aneurysm involving a blood vessel or a tumor at the base of the skull wrapping around a blood vessel, surgeons eliminate the problem vessel by replacing it with an artery from another part of the body. [43]
Patients with aneurysms which have a diameter less than 5 cm are at <1% rupture risk per year. When the aneurysm meets size criteria it can be treated with aortic replacement or EVAR. Thoracic. Thoracic aortic aneurysms are contained in the chest. Aneurysms of the descending aorta can often be treated with thoracic endovascular aortic repair or ...
It can also be used to reduce blood supply to tumours or growths in the body, and therefore restrict their development. Occlusion can be carried out using a ligature; by implanting small coils which stimulate the formation of clots; or, particularly in the case of cerebral aneurysms, by clipping. [3] [4]
Endovascular coiling is an endovascular treatment for intracranial aneurysms and bleeding throughout the body. The procedure reduces blood circulation to an aneurysm or blood vessel through the implantation of detachable platinum wires, with the clinician inserting one or more into the blood vessel or aneurysm until it is determined that blood flow is no longer occurring within the space.
Some people live with this type of aneurysm for many years without any specific treatment. Treatment is limited to surgery (ventricular reduction) for this defect of the heart. However, surgery is not required in most cases but, limiting the patient's physical activity levels to lower the risk of making the aneurysm bigger is advised.
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.

Aneurysms in the ascending aorta may require surgery at a smaller size than aneurysms in the descending aorta. [14] Treatment may be via open or via endovascular means. [citation needed] Open surgical repair remains the gold standard for thoracoabdominal aortic aneurysm treatment, particularly in patients with connective tissues disease. Rates ...
