SURGEON AT WORK Transposition of the Basilic Vein for Arteriovenous Fistula: An Endoscopic Approach Bernardo D Martinez, MD, FACS, Christopher J LeSar, MD, Thomas J Fogarty, MD, FACS, Christopher K Zarins, MD, FACS, George Hermann, BS The creation of a functional hemodialysis fistula in pa- tients who develop end-stage renal disease (ESRD) has critical importance. The majority of surgeons would agree that a primary radiocephalic arteriovenous fistula is the procedure of choice in new dialysis patients. But in patients who lack adequate forearm vasculature second- ary procedures are indicated. Currently, in the United States, more than 50% of hemodialysis that is performed occurs through polytetrafluoroethylene (PTFE) grafts. 1 Numerous reports have described the various complica- tions of PTFE grafts, including high primary failure rates and multiple thrombotic events during the life of the graft. Because of the frequency of graft thrombosis in these patients yearly surgical intervention may be re- quired. 2,3 Recent reports on longterm upper arm dialysis access procedures, specifically, the transposed brachio- basilic arteriovenous fistula, have shown significant longterm primary patency rates reaching 70% at 8 years. 4 To date there have been no descriptions of a min- imally invasive approach to address the long morbid upper arm dissection needed to create this fistula (Fig. 1). We describe an effective, technically simple, mini- mally invasive surgical approach to create an upper arm transposed brachiobasilic fistula. TECHNIQUE The upper extremity has multiple variations in venous anatomic patterns, necessitating preoperative mapping of both upper arms with duplex ultrasonography to de- termine position and caliber of the veins. The portion of the basilic vein used to create the vascular access arises approximately 10 cm below the anticubital fossa, and courses over the medial epicondyle of the humerus, to lie within the medial bicipital furrow. This vein perforates the deep fascia at approximately one-third the distal ex- tent of the humerus. Using local anesthesia with occa- sional intravenous sedation, a 2.5- to 3.0-cm slightly curved transverse incision is made just medial and 1 cm superior to the anticubital fossa. Dissection continues to expose the brachial artery and the basilic vein, using standard surgical instruments and technique. After as- sessing the quality of these structures within this wound, the basilic vein is liberated along its length by ligating and dividing the visualized venous tributaries. Through this working incision, using conventional techniques, the beginning of a subcutaneous tunnel is created over the basilic vein. This tunnel is extended using the Ethi- con endovein harvesting small spoon dissector (Ethicon Endo-Surgery, Inc, Cincinnati, OH) with a 5-mm, 30- degree endoscope (Fig. 2). This device creates an opera- tive working space, allowing mobilization to proceed along the length of the basilic vein. Dissection is techni- cally achieved with endoscopic instrumentation using an endoscopic curved scissors, endoscopic forceps, and a pigtail or ring linear dissector. An endoscopic endoclip- ping device is used to obtain vascular exclusion and al- low division of the subcutaneous venous tributaries. Dissection proceeds along the length of the basilic vein under endoscopic vision to carefully avoid injury to the medial cutaneous nerve, which is found surrounding the vein superiorly and inferiorly along its length. Next, the basilic vein is followed as it dives and penetrates the aponeurotic fascial plane. It is critical to meticulously perform this maneuver to avoid injury to the median and ulnar nerves adjacent to the vein in this region. When the appropriate length of the vein has been liberated above and below the anticubital fossa, a 1-cm transverse counter incision is placed directly over the basilic vein 2 cm inferior to where the pectoralis major muscle inserts into the humerus. The vein is retrieved through the uppermost incision and, under gentle dila- tion with dilute heparin saline, all tributaries that have No competing interests declared.
