This non-invasive method uses concentrated beams of radiation to step by step close off the fistula after a while. It’s like utilizing a significant-tech laser to seal from the problematic connection, and not using a single incision. The brain fistula Restoration time could vary substantially dependant upon the treatment approach and particular person elements.
