Figure 1 A typical patient, aged 47 years old, received therapeutic selective nerve root block (SNRB)Magnetic resonance imaging (MRI) by a MRI scanner (Discovery MR750, GE Healthcare, USA) indicated left lateral recess stenosis and compressed nerve root caused by the posterior protrusion of the left side at the L4–5 level (A, T2W1; B, cross-section, arrow). Under digital subtraction angiography fluoroscopy (INNOVA2100, GE Healthcare, USA), both in the anteroposterior (C) and lateral view (D) revealed that the tip of the puncture needle was passing through the foramen of the exiting L4 nerve root (arrow).
