Editing Arterial exposures (section)

=== '''Mid-forearm:''' ===

** Supine, with arm abducted to 90 degrees on arm board
** 5cm longitudinal incision is made over the portion of the artery to be exposed (can do a long single incision to harvest the entire artery). Landmark is the medial edge of brachioradialis, or a line from the midpoint of antecubital crease to the styloid process of the radius.
** Incise antebrachial fascia along the medial border of brachioradialis
*** In the proximal and middle thirds of the forearm, the radial artery lies beneath the medial fibres of brachioradialis and can be exposed by retracting brachioradialis and pronator teres muscles apart
*** In the distal forearm, the radial artery lies just beneath the antebrachial fascia, between the tendons of brachioradialis and FCR.
*** In the middle third of the forearm, the superficial radial nerve is closely associated with the radial artery and must be carefully preserved
** Radial artery accompanied by paired veins throughout its course
