title: A 6-Fr guiding catheter (Slim Guide(®)) for use with multiple microdevices.
abstract: BACKGROUND
  We developed a new 6-Fr guiding catheter (Slim Guide(®)) that features a large lumen (0.072 inch) for performing advanced techniques as are required in patients with wide-necked aneurysms whose treatment with a single microcatheter is difficult.
  
  
  METHODS
  The Slim Guide was used to address 30 saccular and 20 dissecting aneurysms. All 50 patients presented with subarachnoid hemorrhage. To perform the advanced techniques we used SL-10(®) or Excel 14(®) and Hyperform(®) balloon microcatheters.
  
  
  RESULTS
  Of the 30 patients with saccular aneurysms, 20 were treated with the double microcatheter- and the other 10 with the balloon assist technique. All 20 patients with dissecting aneurysms were treated with the double microcatheter technique. We encountered slight interference during the treatment of one saccular aneurysm with the balloon assist technique using the Slim Guide guiding catheter; another patient with a saccular aneurysm treated with the balloon assist technique suffered a minor transient ischemic complication.
  
  
  CONCLUSIONS
  With the Slim Guide, the risks inherent in the application of advanced techniques may be decreased. Its use facilitates the coil embolization of aneurysms that pose treatment challenges.
