Schematic representation shows the extracranial cerebrospinal venous system, a complex freely communicating network, with the only valve placed in the proximal left (IJVl) or right internal jugular vein (IJVr). The arrows refer to physiologic flow direction. The percentage rate indicates the location and the prevalence of venous stenoses observed in course of chronic cerebrospinal venous insufficiency. AZY, azygous vein; IVC, inferior vena cava; L REN, left renal vein; LV, lumbar veins; PterPlex, pterygoid plexus, one of the major intra-extracranial venous collateral pathways; SVC, superior vena cava; VPlex, vertebral plexus; VV, vertebral vein.

B, In the same patient, the outflow is further hampered by a hypoplasia below the arch (arrow), with a long reflux extended downward the hemiazygous (E-AZY). C, Endovascular percutaneous transluminal angioplasty. D, Postoperative results show reflux disappearance and restored venous calibre.

Selective venography shows (A) a dramatic twisting of the azygous vein just below the arch with reflux toward the spine and (B) endovascular correction by stent insertion and reflux disappearance.Selective venography shows (A) a dramatic twisting of the azygous vein just below the arch with reflux toward the spine and (B) endovascular correction by stent insertion and reflux disappearance.
