Veins along the course of the sciatic nerve Nicos Labropoulos, PhD, DIC, RVT, Apostolos K. Tassiopoulos, MD, Antonios P. Gasparis, MD, RVT, Brett Phillips, MD, Peter J.

Fig 1 Imaging of the sciatic nerve by duplex ultrasound. a, Long view of the sciatic nerve at midthigh. It is seen below the muscle at 4 cm from the skin. It is very echogenic and measured 7.8 mm proximally and 5.2 mm distally. b, Transverse view of the sciatic nerve at midthigh. It is seen below the muscle at 4 cm from the skin. It is very echogenic and measured 7.8 × 6.5 mm. Journal of Vascular Surgery 2009 49, 690-696DOI: (10.1016/j.jvs.2008.09.061) Copyright © 2009 The Society for Vascular Surgery Terms and Conditions

Fig 2 Patterns of extraneural drainage from sciatic nerve veins. a, Direct venae nervora; direct drainage is seen form the nerve to the vena comitantes. b, Indirect venae nervora; veins from the nerve unite with surrounding veins (mostly muscular) and drain into the vena comitantes. c, Periarterial venous plexus; veins from the nerve drain into the periarterial venous plexus, which in turn empties into the vena comitantes. d, Perivenous venous plexus; veins from the nerve drain into a perivenous venous plexus, which surrounds, runs parallel and empties directly into subcutaneous veins.

Fig 3 Varicose veins within and outside the sciatic nerve. a, These veins run spirally along the course of the nerve and their diameter ranged from 1.4 to 3.7 mm. b, Prolonged reflux is seen in a vein outside the sciatic nerve.

Fig 5 Varicose veins within the sciatic nerve. a, Schematic drawing of varicose veins within the perineurium and the sciatic nerve. b, Sciatic nerve at midthigh with varicose veins within the nerve (arrow) in a patient who presented with pain and swelling. A larger refluxing vein is also seen in adhesion with the nerve.
