This study sought to evaluate a new method that uses injection of fibrin sealant under simultaneous balloon occlusion for the treatment of postinterventional access site bleeding complications. With the rising complexity of interventional procedures, iatrogenic false aneurysms and active bleeding has become more common. In general, these complications are associated with increased morbidity and mortality, especially if surgical repair is required. Although high success rates are reported for ultrasound-guided compression and ultrasound-guided thrombin injection, these methods are not always feasible. All procedures of fibrin sealant injection under simultaneous balloon occlusion for the treatment of postinterventional access site bleeding complications or pseudoaneurysm were prospectively collected. Additional data were retrospectively obtained and analyzed for all patients treated by this new method. In total, 53 patients were included from 2018 to 2021. Most of the access site complications were related to transcatheter aortic valve replacement (40%) or percutaneous coronary intervention (21%), but also to a wide variety of other procedures. Of the 53 patients, 30 had to be treated for false aneurysms and 23 for active bleeding. A high primary success rate of 94% was achieved. Recurrences of false aneurysms occurred in six patients, of which only one needed open surgical repair. Regarding complications, two peripheral embolisms, thereof one requiring additional stent implantation occurred. Balloon-assisted thrombin injection seems to be feasible and safe. It provides a new alternative to prevent surgery for patients where common techniques are unavailable or have failed., (© 2022 The Authors.
