Pitfall of superselective catheterization by 3F catheter for spinal arteriovenous malformation.
We experienced a case of subarachnoid rupture of a spinal arteriovenous malformation (AVM) following the injection of contrast medium through a 3F wedged catheter inserted into the feeding artery. If blood does not come through the catheter in the feeding artery of a spinal AVM, not even test injection should be done, to avoid rupture of the spinal AVM.
