title: Scaled clips for aneurysm surgery: technical note.
abstract: OBJECTIVE
  The tips of clip blades are often invisible during operations on large, deep, or posteriorly projecting aneurysms. To overcome this problem, we sought to develop a series of scaled clips.
  
  
  METHODS
  We made scaled clips modified from Yaşargil titanium clips. The blades of the new clips are scaled every 5 mm from the tips with alternating colors. We have added six new types of straight scaled clips.
  
  
  RESULTS
  To date, we have performed approximately 40 aneurysm clippings using the new scaled clips and have confirmed their usefulness.
  
  
  CONCLUSIONS
  Scaling on the blades helps confirm accurate placement of a clip, even during operations for large, deep, or posteriorly projecting aneurysms, in which blade tips are often invisible.
