Materials and methods: Depending on the actual anatomy, presence of a fistula and planed therapeutic aim several endoscopic maneuvers were made to close the defect: leakage combined with cutaneous fistula: combination of modified endoscopic plug implantation and percutaneous vacuum therapy (n=6), giant...
Fistulae often arise from the aortic root or the left ventricular outflow tract [24]. Aortic root fistulas form communications between the aorta and cardiac chambers (aortocavitary) and/or pericardial space (aortoperi- cardial) and often result in hemodynamic compromise. Fistulas can also arise ...
Liquid embolics are less often used in this situation due to rapid flow through the fistula and difficulty achieving target embolization and occlusion without embolization through the venous side to nontarget locations [8]. Type IIa presents with a typical AVM nidus, and either transarterial access...
