Tóm tắt

In this work on vascularization of digital nerves, we have studied the anatomy of the deep network of venae comitantes of digital arteries, and the system of superficial palmar venules. 22 specimens of nerve and artery were dissected as one unit and were infused with Microfil prior to study under the microscope. The deep venous network, a satellite of the digital artery, can be classified into four types. A true network of deep venae comitantes exists in three of these four types, drained by deep veins arising from the transverse anastomotic arches between the palmar digital pedicles. Vascularization of the digital nerve is supplied by numerous anastomotic vessels connecting epineurial vessels, digital artery and the periarterial network (venae comitantes and vasa vasorum). This anatomical configuration lends itself to vascularized nerve grafting; for example, it is possible to use a nerve/artery graft taken as a unit from an amputated finger unsuitable for replantation. Two types of valves in this superficial venous network have been identified and their function is discussed.
