title: Amplatzer Vascular Plug Anchoring Technique to Stabilize the Delivery System for Microcoil Embolization.
abstract: OBJECTIVE
  To evaluate the feasibility of a novel embolization technique, the Amplatzer vascular plug (AVP) anchoring technique, to stabilize the delivery system for microcoil embolization.
  
  
  METHODS
  Three patients were enrolled in this study, including two cases of internal iliac artery aneurysms and one case of internal iliac arterial occlusion prior to endovascular aortic repair. An AVP was used in each case for embolization of one target artery, and the AVP was left in place. The AVP detachment wire was then used as an anchor to stabilize the delivery system for microcoil embolization to embolize the second target artery adjacent to the first target artery. The microcatheter for the microcoils was inserted parallel to the AVP detachment wire in the guiding sheath or catheter used for the AVP.
  
  
  RESULTS
  The AVP anchoring technique was achieved and the microcatheter was easily advanced to the second target artery in all three cases.
  
  
  CONCLUSIONS
  The AVP anchoring technique was found to be feasible to advance the microcatheter into the neighboring artery of an AVP-embolized artery.
