Vascular access through the puncturing of the femoral artery has been for many years the basic procedure for percutaneous diagnostic and therapeutic coronary interventions. This access, however, has been related to numerous and serious complications so other areas for a vascular approach have been investigated. In many clinical trials, the benefits of radial artery puncture have been proven and nowadays it is the preferred one. Nevertheless, this access is not free from complications, among which the most important is the post-procedural radial artery occlusion. Due to the increasing number of repeated coronary procedures, this complication makes it impossible to reuse the radial artery as vascular access. Recently there have been reports of the possibility of using the distal part of the radial artery in the area of the anatomical snuffbox [1].
The possibility of maintaining patency of the radial artery in the traditional (proximal) site, even despite occlusion of the distal part, is one of the advantages of this puncture site. Moreover, with this approach antegrade flow through the superficial palmar arch will be maintained in the case of thrombosis at the puncture site. An additional convenience is the superficial position of the radial artery on the osseous medium within the distal access, which enables precise compression and shortening of the hemostasis period. The risk of an arterio-venous fistula and nerve injuries in the place of the snuffbox should also be negligible. Left-sided access from the snuffbox enables ergonomic performance of the procedure by placing the left upper limb on the right groin of the patient, and in the case of the right-sided access the examined limb can be positioned in a more physiological position.
A 69-year-old man presented with unstable angina pectoris. Coronary intervention was performed via distal radial access. Despite a well-palpable pulse, ultrasonography (Figure 1 A) was performed before the procedure, in order to ascertain that the vessel was sufficient to puncture. Routine local anesthesia using 1 ml of 2% lidocaine was used. The right radial artery was punctured in the area of the anatomical snuffbox using a 20 G metallic entry needle with the anterior wall modified Seldinger technique, and next a 0.038’’ 45 cm long mini-guidewire was advanced through the needle.
A 6 Fr 10 cm long sheath (Radifocus Introducer, Terumo) was inserted (Figures 1 B–D), and then spasmolytic...
