epidural venous plexus plays a crucial role for the generation of vascular back pain, in particular in those conditions characterized by venous congestion, such as heart failure or pregnancy. Except some rudimental cuspids, the vertebral venous system is considered to be a valveless anastomotic system; as a result the blood is supposed to flow in either direction depending on changes of cardiovascular conditions during the day. Within the narrow boundaries of the neural canal, the epidural veins can therefore get congested, inducing low back pain. The aim of this case report was to highlight a correlation between lumbar superficial veins in patients with chronic low back pain and epidural deep venous plexus congestion. The patients selected underwent a morphologic examination of venous epidural plexus (included its connections with lumbar superficial blood vessels) through a 3D dynamic contrast-enhanced Magnetic Resonance Angiography. The Authors found two different radiological behaviours: total and partial congestion of the vertebral deep venous system. Clinical consequences were discussed and therapeutic strategies were suggested. © PI-ME.
