Temporary Vessel Occlusion by Microvascular Clips
Microvascular procedures for cerebral aneurysms or revascularization of small arteries require the application of microvascular clips. In 1911, CUSHING  became the first to describe the application of vascular clips for the occlusion of bleeding cerebral vessels. Increasingly authors are recommending the application of some temporary clips before preparation and occlusion of an aneurysm without regard to possible vessel wall lesions being caused by the clips themselves. To ensure the successful performance of the finest surgical techniques these clips are expected to bring about the temporary occlusion of a cerebral vessel combined with minimal vessel wall lesion. We therefore set out to study the effects of different microvascular clips with a diameter of 1–2 mm on the vessel wall and measured blood flow in the temporarily clipped arteries.
