Abstract:
Recently, accumulation of knowledge on cerebrovascular microanatomy and its hemodynamics and advances in interventional equipments, especially microcatheters, could make superselective embolization as well as for an adjunctive preoperative procedures The authors performed superselective angiography and embolization with Tracker microcatheter in 25 procedures out of 15 patients with brain arteriovenous malformations (AVMs). Complete embolization was done in 7 prtients (46.7%), nearly complete embolization in 6 patients(40.4%), and partial embolization in 2 patients (13.3%). The overall curative success rate of embolization was 86.7%. Five patients showed no complication at all. Mild complications, however, were observed in 7 patients (46.8%). Severe complications such as AVM or Tracker rupture were observed in 3 patients (20%). In conclusion, superselective embolization is and effective method for the treatment of brain AVMs, and multiple session embolizations could reduce the complication rate and increase the success rate.
