Abstract:
The blood supply and source about the sciatic nerve in 20 fetuses were studied. We observed the number and diameter of the branches of blood vessels and the size, characteristic distribution of the network formed from them, microscopically and by naked eye. A combined angiography was used. After injection of Chinese ink the epineuria were peeled. About the vascular distribution of the nerve tract we perceived that:1. The blood supply of the sciatic nerve was from two vascular systems——external and internal (separated by the perineurium); 2. The external part showed segmental of multiple origination, mainly from the nutrition arteries, and some arterioles directly from the sciatic arteries. The number, diameter, branching type of the vessels, size and shape of the anastomosing network were also observed; 3. The internal part consisted of microarteries and capillaries, which form an anastomosing network. The diameter of the vessels, shape and size of the network were measured.In view of the above-mentioned data, when a part of the sciatic nerve should be isolated, the clinical physicians ought to consider the blood supply in segmental character, so that the part of nerve taken off must not be too long to avoid injuring the nutritional vessels.
