We have previously reported that the rapid atrial swirl sign (RASS) is an accurate and safe procedure for ultrasound (US)-guided tip positioning of retrograde-tunneled hemodialysis catheters (HDCs). However, application of RASS for placement of antegrade HDCs has not been investigated yet. Therefore, we here report our first experience of applying RASS for US-guided tip positioning of antegrade-tunneled HDCs.
We performed a cross-sectional study to assess the feasibility of applying the RASS for US-guided tip positioning of antegrade-tunneled HDCs. We included a total number of 15 antegrade-tunneled HDC insertions in 13 patients requiring placement of a HDC for the temporary or permanent treatment of ESKD in a single-center, cross-sectional pilot study.
The overall success rate of applying the RASS for US-guided tip positioning of antegrade-tunneled HDCs was 15/15 (100%) confirmed by portable anterior-posterior chest radiography, with no major adverse events after HDC insertions. In addition, this insertion technique demonstrated optimal HDC flow without any observed malfunction.
This study investigated the efficacy of the RASS for US-guided tip positioning of antegrade-tunneled HDCs in patients with ESKD. Application of the RASS for US-guided tip positioning is an accurate and safe procedure for proper placement of antegrade-tunneled HDCs.
我们之前曾报道过，快速心房涡流征（RASS）是一种准确、安全的超声（US）引导下逆行隧道血液透析导管（HDC）尖端定位方法。然而，RASS 在前向 HDC 置管中的应用尚未得到研究。因此，我们在此报告我们首次应用 RASS 进行 US 引导下前向隧道 HDC 尖端定位的经验。
我们进行了一项横断面研究，以评估 RASS 在前向隧道 HDC 的 US 引导尖端定位中的可行性。我们共纳入了 13 例患者的 15 例前向隧道 HDC 置管，这些患者需要置管以临时或永久治疗终末期肾病，这是一项单中心的横断面试点研究。
通过便携式前后位胸部 X 线片确认，15 例（100%）前向隧道 HDC 的 RASS 引导 US 尖端定位均获得成功，HDC 置管后无重大不良事件。此外，该插入技术显示出最佳的 HDC 流量，无任何观察到的故障。
本研究探讨了 RASS 在伴有终末期肾病的患者中用于 US 引导的前向隧道 HDC 尖端定位的疗效。RASS 用于 US 引导的尖端定位是一种准确和安全的方法，可正确放置前向隧道 HDC。
