The fasciotomy is performed to enhance visualization by
opening up the tunnel. Additionally, it can reduce the risk
of compartment syndrome if there is any bleeding post-
operatively.
To begin, withdraw the endoscope from the tunnel, leaving
the BTT in place. Remove the Dissection Tip from the end of
the endoscope. Insert the endoscope and the BiSECTOR™
tool into the Harvesting Cannula. Replace the 7 mm
Endoscope Seal with the Harvesting Cannula Seal.
Using the BiSECTOR tool, perform fasciotomy using sharp
transection, during which cautery is applied. Set the bipo-
lar generator wattage according to recommendations in
the VASOVIEW 7 xB Endoscopic Vessel Harvesting System
Instructions For Use (settings differ by type of generator). The
fascia should be released from the distal forearm to the mid
or proximal forearm. (Figure 39)

Once the fasciotomy is complete, begin branch transection.
Perform the branch cauterization and transection at a safe
distance from the artery. Use the C-Ring to stabilize the pedi-
cle and to maintain a consistent distance between the pedicle
and the BiSECTOR tool. Using the C-Ring can ensure that the
integrity of the radial artery conduit is preserved by maintai-
ning a distance of 3 – 5 mm between the pedicle and the
BiSECTOR tool during branch transection. (Figure 40) Watch
the vessel branch during cautery; typically 1 to 2 seconds of
cautery will be needed depending upon branch size. Work
proximal to distal (elbow to wrist). The proximal end of the
pedicle is indicated by the recurrent radial artery.
Upon reaching the distal end of the pedicle, use the C-Ring
to run the pedicle, ensuring that all branches have been
transected.
