To assess left radial artery size, technical feasibility and safety of ldTRA in the anatomical snuffbox for percutaneous image-guided procedures.
A retrospective single-center study was performed from November 2016 to June 2018 on all patients undergoing ldTRA for interventional radiology procedures.
A total of 287 patients (91 female and 196 male), aged 18-94 years (mean age 64 years), were included. 389 procedures were performed which included hepatic chemoembolization (n = 161), selective internal radiation therapy Y-90 mapping (n = 74), selective internal radiation therapy Y-90 administration (n = 48), diagnostic angiography (n = 34), mesenteric and pelvic embolization (n = 59), stent insertion (n = 8) and miscellaneous (n = 5). Mean sonographic measurement of the left radial artery size at the conventional site at the wrist was 2.55 mm (range 1.4-3.3 mm) and 2.34 mm (range 1.4-3.2 mm) at the anatomical snuffbox (p < 0.001). Technical success rate was 100%, a single small hematoma occurred in the first patient (0.3%). 74.2% of patients had follow-up for radial artery patency (mean 46 days, range 0-66 days), which did not reveal radial artery occlusions or pseudoaneurysm formation.
The left distal radial artery in the anatomical snuffbox is smaller in comparison with the conventional access site at the wrist. The difference however is small and does not require intentional downsizing of vascular access equipment to facilitate utilization of ldTRA. Assessment of the vessel size is imperative for appropriate equipment selection and optimizing procedural success. This study supports that ldTRA is technically feasible and safe.
评估经皮影像引导介入放射学操作中解剖鼻烟窝内左桡动脉（ldTRA）的大小、技术可行性和安全性。
本研究为 2016 年 11 月至 2018 年 6 月在所有因介入放射学程序而接受 ldTRA 的患者中进行的回顾性单中心研究。
共纳入 287 例患者（91 例女性，196 例男性），年龄 18-94 岁（平均年龄 64 岁）。共进行了 389 次操作，包括肝动脉化疗栓塞术（n=161）、选择性内部放射治疗 Y-90 映射（n=74）、选择性内部放射治疗 Y-90 给药（n=48）、诊断性血管造影（n=34）、肠系膜和骨盆栓塞术（n=59）、支架置入术（n=8）和其他（n=5）。常规腕部桡动脉大小的超声测量平均值为 2.55mm（范围 1.4-3.3mm），解剖鼻烟窝处为 2.34mm（范围 1.4-3.2mm）（p<0.001）。技术成功率为 100%，首例患者（0.3%）出现单一小血肿。74.2%的患者（平均随访 46 天，范围 0-66 天）桡动脉通畅性，未发现桡动脉闭塞或假性动脉瘤形成。
与腕部常规入路相比，解剖鼻烟窝内左桡动脉（ldTRA）较小。然而，差异很小，不需要对血管通路设备进行有意缩小，以方便使用 ldTRA。评估血管大小对于适当的设备选择和优化程序成功至关重要。本研究支持 ldTRA 具有技术可行性和安全性。
