Abstract:
OBJECTIVE: The transradial catheterization (TRC) is becoming widespread, primarily for neurointerventions. Therefore, the evaluation of radial artery puncture in clinical practice and a better understanding of the anatomy are important to improve the safety of neuroendovascular surgery. METHODS: Ten formalin-fixed adult Korean cadavers were dissected to expose radial artery (RA), brachial artery (BrA) and subclvian artery (ScA), bilaterally. Vessel lengths and diameters were meaured using a caliper and distance between the specific point of vessels and the anatomical landmarks including the radial styloid process, the medial epicondyle of the humerus, the sternoclavicular joint, and the vertebral artery orifice were also measured. RESULTS: The average length between the radial (RAPS) and the BrA puncture sites (BrAPS) and between the vertebral artery orifice (VAO) and the BrA bifurcation (BrAB) did not differ between sides (p>0.05). The average length between the radial styloid process (RSP) and the RAPS was 13.41+/-2.19 mm, and the RSP was 26.85+/-2.47 mm from the median nerve (MN). The mean length between the medial epicondyle (ME) and the BrAPS as 44.23+/-5.47 mm, whereas the distance between the ME and the MN was 42.23+/-4.77 mm. The average VAO-ScA angle was 70.94+/-6.12degrees, and the length between the ScA junction (SCJ) and the VAO was 60.30+/-8.48 mm. CONCLUSION: This study provides basic anatomical information about the radial artery and the brachial route and can help improving new techniques, selection of size and shape of catheters for TRC. This can help neurointerventionists who adopt a transradial neuroendovascular approach and offers comprehensive and safe care to their patients.
