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.
ISAT sought to measure outcomes of cerebral aneurysm patients at 2 and 12 months using a type of Rankin scale. [5]: 114 The study was prematurely terminated in 2002 after the oversight committee determined there was increased morbidity with surgical clipping compared to endovascular coiling.
Analysis of data from this trial has indicated a 7% lower eight-year mortality rate with coiling, [33] a high rate of aneurysm recurrence in aneurysms treated with coiling—from 28.6 to 33.6% within a year, [34] [35] a 6.9 times greater rate of late retreatment for coiled aneurysms, [36] and a rate of rebleeding 8 times higher than surgically ...
Endovascular aneurysm repair (EVAR) is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair."
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 ...
Angioplasty, also known as balloon angioplasty and percutaneous transluminal angioplasty, is a minimally invasive endovascular procedure used to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis.
Dietrich trained several future leaders in the field of endovascular surgery at the Arizona Heart Hospital including Venkatesh Ramaiah, MD [3] who succeeded him as medical director of the institution in 2010. [4] The development of endovascular surgery has been accompanied by a gradual separation of vascular surgery from its origin in general ...
Percutaneous intentional extraluminal revascularization, or PIER, is an endovascular approach to revascularization of peripheral occlusions that may serve as an alternative to transluminal angioplasty. It is a minimally invasive procedure requiring only local anesthetic, which proves to be a major advantage over invasive surgical bypass ...
