BACKGROUND: The deep and perforating lymphatic anatomy of the upper limb still remains the least described in medical literature.
MATERIALS AND METHODS: Six upper limbs with the axillary tissue were harvested from three unembalmed human cadavers amputated at the shoulder joint. A small amount of 6% hydrogen peroxide was employed to detect the lymphatic vessels around the deep palmar arch, radial and ulnar neurovascular bundles. A 30-gauge needle was inserted into the vessels and they were injected with a barium sulphate compound. Each specimen was dissected, photographed and radiographed to demonstrate deep lymphatic distribution of the upper limb.
RESULTS: Continuing from the deep lymph vessels of the hand, single or multiple deep collecting lymph vessels have been found along the radial, ulnar, anterior and posterior interosseous neurovascular bundles in the forearm, brachial and deep branchial neurovascular bundles in the upper arm. During their courses, lymph nodes were found setting in the trunk of the radial, ulnar and brachial lymph vessels near or in the cubital fossa, and in the axillar. Perforating lymph vessels have been found near the wrist and in the cubital fossa, which linked the superficial and deep lymph vessels. The direction of lymphatic drainage was from the deep to superficial or superficial to deep vessels.
CONCLUSION: The deep lymphatic anatomy of the upper limb has been described. The results will provide an anatomical basis for clinical management, educational reference and scientific research.
