Endoneurial Blood Flow

The blood supply (vasa nervorum) to peripheral nerves is composed of an interconnected dual circulation. The endoneurium of nerve fascicles is maintained by the intrinsic circulation which is composed of microvessels primarily of capillary caliber. Transperineurial arterioles link the intrinsic circulation with the extrinsic arterial supply located in the epineurium. Blood flow in the vasa nervorum is neurogenically influenced (1,2). Although a recent hypothesis proposes that endoneurial blood flow is controlled by the action of autonomic nerve fibers associated with epineurial arterioles (2), our recent studies (3) show that in addition to epineurial arterioles other segments of the vasa nervorum are also innervated. In this study, we examine blood vessels of the endoneurium for possible innervation.

Vascular Compromise

SummaryEleven canine forelimbs were examined using either gross dissection or a modified Spalteholz technique to investigate the blood supply of the palmar metacarpal sesamoid bones. In addition, the sesamoid bones, from two prepared skeletons, were examined for the presence of vascular foramina. Multiple vascular foramina were observed over the sesamoid surface. The most consistent elements of the arterial supply were proximal vessels supplying the axial and dorsal abaxial sides of the bone. In addition, palmar and distal sources often made contributions to the blood supply. Various minor or occasional sources were noted. This study demonstrates that the palmar metacarpal sesamoid bones of the dog have an abundant but highly variable vascular supply.The blood supply of the canine palmar metacarpal sesamoid bones was examined, using several methods, in order to evaluate the possible involvement of vascular compromise in sesamoid disease. It was found that the sesamoid bones have an abundant blood supply which is presumably resistant to disruption.
