ISAT sought to measure outcomes of cerebral aneurysm patients at 2 and 12 months using a type of a Rankin scale. [4]: 114 The study was prematurely terminated in 2002 after the oversight committee determined there was increased morbidity with surgical clipping compared to endovascular coiling.
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.
If possible, either surgical clipping or endovascular coiling is typically performed within the first 24 hours after bleeding to occlude the ruptured aneurysm and reduce the risk of recurrent hemorrhage. [31] While a large meta-analysis found the outcomes and risks of surgical clipping and endovascular coiling to be statistically similar, no ...
A systematic review of the literature and meta-analysis showed that multilevel sleep surgery achieves a 60.3% apnea hypopnea index (AHI) reduction. [2] This reduction in sleep apnea severity via surgical means compares well against the AHI reduction for best case CPAP patients where an overall AHI reduction of 66% was achieved. [3]
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.
[58] [59] This trial, the International Subarachnoid Aneurysm Trial (ISAT), showed that in this group the likelihood of death or being dependent on others for activities of daily living was reduced (7.4 percent absolute risk reduction, 23.5 percent relative risk reduction) if endovascular coiling was used as opposed to surgery.

Two weeks later, they told me I had “high-moderate” sleep apnea and needed to acquire a continuous positive airway pressure, or CPAP, machine, at a cost of about $600.
The operation is a common procedure but in the most extreme cases, children with severe OSA requires special precautions before, surgery (see "Surgery and obstructive sleep apnea syndrome" below). In some countries, a milder surgical procedure called tonsillotomy is used to remove the protruding tonsillar tissue, a method associated with less ...
