    Abstract:
    We describe a novel surgical technique to facilitate the second-stage elevation of the basilic or brachial vein in patients with first-stage brachial-basilic or autogenous brachial-brachial arteriovenous fistula by axial splitting of the medial antebrachial cutaneous nerve (MABCN). Filaments of the MABCN typically traverse the anterior aspect of the basilic and brachial veins. The second-stage elevation/shelf superficialization of the basilic or brachial vein, so as not to cause an injury to the MABCN, requires division of these veins with transposition over the nerve branches and subsequent reanastomosis. Our method of axial splitting of the MABCN enables elevation and shelf superficialization of the basilic or brachial vein without the division and reanastomosis of the vein. Twenty-eight patients underwent this simplified elevation. The nerve perineurium was incised longitudinally, nerve fibers were divided intrafascicularly, and cutaneous nerve branches were retracted aside. The vein was elevated between the divided nerves. On discharge and at 1-month follow-up, only one patient complained of localized patch hypoesthesia as reported in a simplified neurologic assessment questionnaire and neurologic examination.
