Abstract：
UNASSIGNED: The internal jugular vein (IJV) is one of the most used sites for central venous access. Some authors revealed the association of a higher deformation rate of the IJV wall with posterior wall penetration, which may cause a hemorrhagic complication. A newly developed thin-tip needle (three-dimensional (3D) needle) reduced the deformation rate in an ex vivo study. Therefore, we conducted a clinical study to investigate its efficacy in reducing vessel deformity during IJV puncture.
UNASSIGNED: This study retrospectively enrolled 80 adult patients who received central venous port (CVP) implantation via the IJV from April 1, 2022, to November 10, 2023, in our institution. Traditional needle-and-catheter was used for ultrasound (US)-guided IJV puncture (usual group) for the former 40 patients before July 18, 2023. Afterward, the 3D needle was used for the latter 40 patients (3D needle group). US images were stored and analyzed to calculate the deformation rate.
UNASSIGNED: The deformation rate was 58.6% (13.2-100) for the usual needle and 41.8% (10.6-100) for the 3D needle (p = 0.0034). Patients who required several punctures included 2 for the usual needle and 12 for the 3D needle, respectively (p = 0.0032). All patients and the usual needle group demonstrated a weak negative correlation between the deformation rate and pre-puncture vessel diameter (r = 0.24 and 0.41, respectively), with no correlation in the 3D needle group.
UNASSIGNED: The deformation rate of the IJV wall was smaller in the 3D needle group than in the usual needle group. The use of a 3D needle would be safer when puncturing the IJV.

摘要：
■颈内静脉（IJV）是中心静脉通路最常用的部位之一。一些作者揭示了IJV壁的较高变形率与后壁穿透的关联，这可能会导致出血并发症.在离体研究中，新开发的细尖针（三维（3D）针）降低了变形率。因此,我们进行了一项临床研究，以探讨其在减少IJV穿刺过程中血管畸形的功效。
■这项研究回顾性地纳入了我们机构的80名成年患者，这些患者于2022年4月1日至2023年11月10日通过IJV接受了中央静脉端口（CVP）植入。在2023年7月18日之前，前40名患者使用传统的针和导管进行超声（US）引导的IJV穿刺（常规组）。之后,后40例患者使用3D针(3D针组).存储并分析US图像以计算变形率。
■通常的针的变形率为58.6％（13.2-100），3D针的变形率为41.8％（10.6-100）（p=0.0034）。需要多次穿刺的患者包括2个普通针头和12个3D针头，分别(p=0.0032)。所有患者和常规针组的变形率与穿刺前血管直径之间呈弱负相关（r分别为0.24和0.41）。在3D针组中没有相关性。
■3D针组的IJV壁的变形率小于通常的针组。在穿刺IJV时，使用3D针会更安全。
