Pdf Summary

This case report, published in the Journal for Vascular Ultrasound, describes a rare vascular anomaly called persistent sciatic veins. The condition is typically associated with Klippel-Trenaunay-Weber syndrome (KTWS) but can also occur in patients without KTWS. The exact prevalence of persistent sciatic veins is not well-known, but it is estimated to be between 0.7% and 9%. <br /><br />The report presents the case of a 37-year-old woman who complained of pain in her right thigh and knee for three months. The patient underwent a venous duplex ultrasound examination, which revealed duplication of the femoral vein and the presence of a large vein parallel to the sciatic nerve in the posterior thigh. This anomaly was observed in both lower limbs.<br /><br />To confirm the diagnosis, a computed tomography angiography examination was performed, which demonstrated the confluence of the persistent sciatic vein with the deep femoral vein. The persistent sciatic vein served as the main route of deep venous drainage from the limb.<br /><br />The report highlights the importance of recognizing and diagnosing persistent sciatic veins, even in the absence of KTWS, as they can contribute to venous disease. The authors emphasize the role of duplex ultrasound as the initial imaging modality for evaluating lower limb venous disease.<br /><br />Overall, this case report provides valuable insights into the diagnosis and management of persistent sciatic veins, an uncommon vascular anomaly that can have implications for venous health.
