Ultrasound guided localization of inferior gluteal artery for identification sciatic nerve: a case report.

Abstract

Various approaches to sciatic nerve blocks at different levels have been described. In the nineteenth century, landmark techniques were employed for the nerve block, while nowadays, ultrasound-guided nerve blocks are gaining popularity. Despite the array of techniques available, challenges arise due to factors like the intricate gluteal anatomy, challenging sonoanatomy, patient positioning issues, and the learning curve associated with ultrasound and nerve locators. Among these landmarks, the inferior gluteal artery stands out as an easily identifiable feature with ultrasound assistance. We report a case where we used ultrasound to locate the inferior gluteal artery that guides in the identification of the sciatic nerve. In this t echnique, we can identify the nerve immediately as it emerges from the greater sciatic notch. At this level, we can block the nerve to achieve adequate surgical anesthesia and analgesia for tourniquet pain.
