[Vasa vasorum of subcutaneous veins and lymph vessels]

After intraarterial ink-injection the vasa vasorum of veins and lymphatic vessels in adults, dead born children and fetuses were demonstrated micropreparatorily. In their walls the larger veins of the saphena system possess a capillary network corresponding to the connective tissue and muscle structures/patterns in the vessel wall. No vasa vasorum could be found in the subcutaneous veins less than 1 mm in diameter. The lymphatic vessels of the inner prefascial bundle show a one-dimensional capillary network in the outer layers of the wall. Like the vasa vasorum of the saphena system it develops in the second half of fetal life.
