Aneurysm clipping aims towards optimal obliteration of an aneurysm without narrowing or occluding the parental of branching vessels. In the beginning of aneurysm clipping post surgical angiography was the only method to prove optimal clip position.Unfortunately post surgical angiography showed what went wrongduring surgery in retrospect. Even that intraoperative angiography showed excellent results in optimizing clip application and reducing the risk of residual aneurysm and vessel stenosis the method has also disadvantages. The mean time needed to draw conclusions is about 20 minutes. In case of vessel occlusion 20 minutes could be enough to lead to brain infarction andclip correction was too late in 33% of cases. Additionally, the use of the contrast enhancement agent could lead to adverse effects like hypotension and even death through cardiopulmonary decompensation.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
