Improved technique of bucrylate embolisation in brain arteriovenous malformation. The use of additional temporary balloon occlusion.
Problems currently limiting the success and safety of calibrated leak balloon embolisation include suboptimal occlusion of malformation bed due to multiple or inaccessible pedicles and neural deficits due to paradoxical embolisation of normal brain. Analysis of preliminary calibrated leak balloon angiograms supported by temporary balloon occlusion of other pedicles yields insights into the dynamics of blood flow to anterior malformations. Strategies have been devised using temporary balloon occlusion to improve filling of malformation bed and reduce paradoxical embolisation of eloquent brain.
