Spinal arteriovenous malformation dissection using venous varix working space

April 4, 2026Michael T. Lawton, MD

Michael Lawton describes a surgical technique where a large venous varix or encephalomalacia can create working space inside the spinal cord to circumferentially dissect a spinal AVM nidus and reach anterior spinal artery feeders.

It may sound crazy, but a large venous varix or encephalomalacia from prior hemorrhage can create working space within the spinal cord
to circumferentially dissect a spinal AVM nidus
reach anterior spinal artery feeders coming from the ventral cord surface.
