Anatomical variations of the brachial plexus may be important in regional anesthesia and upper limb procedures. A fused single cord of the brachial plexus, although considered rare, was discovered in 4 Indian male cadavers during the dissection of 90 brachial plexuses. All 4 cases demonstrated deviation from the usual pattern starting at the division of trunks continuing to the formation of cords. The location of these single cords was lateral to the axillary artery instead of the typical perivascular relationship. A fused single cord of brachial plexus might be more common than previously thought. The impact on the performance or success of blockade remains unknown.
臂丛的解剖变异在区域麻醉和上肢手术中可能很重要。在解剖 90 个臂丛时，在 4 具印度男性尸体中发现了融合的单一臂丛神经索，尽管这种情况被认为很少见。所有 4 例均表现出与通常模式的偏差，从干的分离开始，一直持续到索的形成。这些单一索的位置位于腋动脉的外侧，而不是典型的血管周围关系。融合的单一臂丛神经索可能比以前认为的更为常见。对阻滞效果或成功率的影响尚不清楚。
