Compression of Brachial Vein between Two Lateral Roots of Median Nerve -A Case Report

During gross anatomy dissection, variation in the formation of median nerve of the upper limb was discovered in the right upper extremity of a 57-year-old male cadaver. Three roots contributed to the formation of median nerve instead of usual two roots i.e. two lateral roots and one medial root. After being formed the median nerve descended medial to the axillary artery. Between the two lateral roots brachial vein passed to open into the axillary vein. Anatomical variations in the formation of nerves and their unusual relationship to the surrounding structures can be the cause of nerve compression syndromes and vascular problems.

Short Axillary Vein and an Axillary Venous Ladder Formed by Basilic and Brachial Veins – An Anatomical and Clinical Perspective

Knowledge of anatomic variants of veins in the arm and axilla play a key role in planning of successful venous access. Possible anatomic variants of axillary vein, brachial vein and basilic vein and their clinical implications have been well described in the literature. We report a rare case of formation of a short axillary vein associated with complex venous communications between the basilic and brachial veins forming a venous ladder in the axilla, in formalin embalmed male cadaver. Axillary vein was formed in the upper part of the axilla by the fusion of basilic vein and unpaired brachial vein, and it was about 3cm in length. The higher-up confluence of basilic and brachial veins was also associated with presence of three communicating veins between the basilic and brachial veins in the axilla. Knowledge of reported venous variations is very useful during preoperative venous mapping and also for planning and execution of various surgical invasive procedures involving these veins.

Clinical Study of Brachial Vein Transposition Fistulas for Hemodialysis / 日本心臓血管外科学会雑誌

Brachial vein transposition fistulas for hemodialysis are embloyed when the superficial veins in arms are not used. In our hospital, 28 patients have received brachial vein transposition fistula in the past 13 years. Post-operative complications were bleeding at the puncture sites in 2 patients, infection at the puncture site in 1, and aneurysm formation in the transposed vein in 1. Access related hand ischemia and venous hypertension were not recognized. For 3 patients of fistula stenosis, percutaneous catheter dilatation was performed. For 2 of 19 patients with fistula occlusion, surgical thrombectomy was performed. The primary patency rates were 76.8% at 1 year and 55.8% at 4 years. The secondary patency rates were 95.5% at 1 year and 66.3% at 4 years. The brachial vein transposition procedure is useful for long-term continuation of hemodialysis using autologous arm vessels.
