Abstract

Background: Paraneural sheath engulfing the sciatic nerve (SN) between the ischial tuberosity and the greater trochanter is well known.

Methods: In order to explore the anatomical planes separating the paraneurium from the epineurium in SN, we conducted a cadaveric study (two patients and four specimens), followed by a clinical study in 10 patients.

Results: We demonstrated an elevation of 5-7 layers of paraneural tissues after an in-plane injection in the longitudinal axis of the proximal SN, which was possibly the last of the paraneural sheath. In the clinical study, the block provided low pain scores with no rescue analgesia postoperatively and no neurological deficit at the time of discharge.

Conclusion: This is probably the first series which has described the elevation of several layers of paraneural tissues after an in-plane injection in the longitudinal axis of the proximal SN.

大转子水平纵轴上的硬膜旁坐骨神经鞘：超声尸体与临床相关性研究。

背景坐骨神经(SN)位于峡部结节和大转子之间，其副神经鞘吞噬坐骨神经(SN)是众所周知的：为了探索坐骨神经鞘旁与坐骨神经外膜之间的解剖平面，我们进行了一项尸体研究（两名患者和四份标本），随后对 10 名患者进行了临床研究：结果：我们发现，在近端 SN 的纵轴进行平面注射后，5-7 层的硬膜旁组织隆起，这可能是硬膜旁鞘的最后一层。在临床研究中，该阻滞术的疼痛评分较低，术后无需镇痛抢救，出院时无神经功能缺损：这可能是第一个描述在近端鼻窦纵轴平面注射后多层硬膜旁组织隆起的系列研究。

期刊介绍： The Journal of Medical Ultrasound is the peer-reviewed publication of the Asian Federation of Societies for Ultrasound in Medicine and Biology, and the Chinese Taipei Society of Ultrasound in Medicine. Its aim is to promote clinical and scientific research in ultrasonography, and to serve as a channel of communication among sonologists, sonographers, and medical ultrasound physicians in the Asia-Pacific region and wider international community. The Journal invites original contributions relating to the clinical and laboratory investigations and applications of ultrasonography.
