2 Endoscopic Removal of the Radial Artery Background Endoscopic removal of the great saphenous vein is a well established technique during coronary artery bypass surgery and proved to offer significant advantages in terms of wound complications, reduced pain and aesthetics while yielding remarkable results with respect to the histological analysis of the harvested conduits. [1] The use of the radial artery for myocardial revascularization offered excellent results when compared to saphenous vein grafts in terms of improved clinical outcome, higher graft patency rate and a lower incidence of late cardiac events. [2,3] Therefore, following the recent revival of the radial artery as the second conduit of choice for total arterial myocardial revascularization, a vivid interest for endoscopic radial artery harvesting was developed in order to obtain the same clinical benefits as in endoscopic vein harvesting. Advantages of endoscopic radial artery harvesting The use of the endoscopic approach for radial artery harvesting offers several advantages when compared to the open technique in terms of [4,5]: Less neurological complications Less wound complications Less wound infections Less hematomas Improved aesthetics Moreover, the endoscopic technique provides ample patients satisfaction, especially in terms of length of the surgical incision (Fig. 1) when compared to the conventional approach (Fig. 2). Figure 1: Endoscopic Technique: one or two 2 cm incisions are performed Figure 2: Conventional technique: a cm incision is performed

3 2 3 Advantages of the BISLERI Endoscopic Radial Artery Retractor Despite the excellent performance of the Endoscopic Vein Retractor already on the market, the different anatomical features of the radial artery made the develop ment of a novel retractor necessary. In fact, the great saphenous vein runs in the subcutaneous tissue, while the radial artery lies mostly beneath the brachioradialis muscle.

4 The clinical experience with this novel tool allowed to harvest safely and effectively the radial artery endoscopically and full-length even in the most difficult cases (i.e. patients with considerable amount of fat tissue in the subcutaneous layers or with well-developed muscular forearm). Endoscopic radial artery harvesting can be performed concomitant to left internal mammary artery preparation, with an average procedural time of minutes by trained surgeons. As an increasing number of novel technologies for vessel sealing are becoming available on the market, it will be up to the surgeons choice the preferred energy source or system to be used along with the BISLERI Endoscopic Radial Artery Retractor. Therefore, this novel tool offers a unique improved design for endoscopic radial artery harvesting and is extremely cost-effective thereby filling a definitive need in field of minimally invasive conduit harvesting. Surgical technique for endoscopic radial artery harvesting Following Allen test or Doppler evaluation of the radial artery, the non-dominant forearm is conventionally prepared and draped as in the conventional technique, with the arm abducted around 90. Moreover, care should be taken in placing a rolled pad below the wrist for adequate exposure by extending the hand (Fig. 3a). No tourniquet around the arm is used, since the pulsation of the radial artery can represent an important landmark especially in difficult cases. A 2 to 2.5 cm longitudinal incision of the volar surface of the forearm is performed beginning 1 cm proximal to the radial styloid prominence (Fig. 7); the fascia between the brachioradialis and the flexor carpi muscles is then divided and the dissection of the radial artery as a pedicled graft is started under direct vision (Fig. 8). Fig. 7 Fig. 8 Once enough space has been created, the Bisleri Endoscopic Radial Artery Retractor is inserted into the subcutaneous tissue and advanced toward the antecubital fossa (Fig. 9); during such maneuvers, the fascia is divided and the RA visualized. (Fig. 10)

Fig. 9: External view or the retractor once positioned in the forearm Fig. 10: Endoscopic view during opening of the fascia A careful dissection around the pedicled RA is then carried out by means of the vessel sealing system alone (Fig. 11): in particular, whenever a prominent brachioradialis muscle is present, it is highly recommended to start the dissection and the division of the side branches from the brachioradialis muscle side and then on the flexor carpi side, since in such cases the radial artery is likely to slip beneath the brachioradialis muscle thus making endoscopic harvesting cumbersome. Once the full length of the RA has been harvested, the arterial dissector (hook) is used in order to assess the potential presence of residual side branches (Fig. 12). Fig. 11 Fig. 12 Finally, an additional 1.5 cm incision is performed near the antecubital space for proximal ligation (Fig. 13); following full heparinization, the RA is divided distally,

Otherwise, the radial artery can be ligated proximally by means of an endoloop through the single, distal incision. 15 days postoperatively, the surgical scars are completely healed with excellent aesthetic results (Fig. 14).
