title: Three dimensional rotational angiography in surgical planning of aneurysm clipping.
abstract: BACKGROUND
  Three-dimensional (3D) angiography is increasingly used in the diagnostics of brain aneurysms. Aim of the present study was to evaluate the accuracy of 3D angiograms with respect to its value for preoperative planning of aneurysm clipping.
  
  
  METHODS
  The 3D angiograms of 42 patients with subarachnoid bleeding caused by aneurysm rupture of the anterior circle of Willis and the intradural carotid have been compared to intraoperative photographs of the aneurysms.
  
  
  RESULTS
  Neighbouring vessels, aneurysm anatomy, arteries originating from the aneurysm wall were accurately shown decreasing the surgical risk of aneurysm clipping.
  
  
  CONCLUSIONS
  The 3D images enabled a perfect preoperative planning through the operation by illuminating the aneurysm anatomy, neck localisation and shape and relation of the aneurysm to neighbouring vessels. Operative approach, use of an accurate clip and avoidance of clipping arteries close to the aneurysm have become predictable and safer by the use of 3D angiography.
