[Individual variability in the structure and topography of the celiac plexus and its clinical significance].

Using anatomical and histological methods individual variability of structure and topography of coeliac plexus 94 preparations of adults of both sexes were studied. In 32% coeliac plexus was presented as a multitude of small ganglia connected by a network of nerve fibres remote from visceral branches of aorta. In 38% the plexus was composed of middle sized ganglia concentrated into groups at the level of coeliac trunk from the left and at the level of the source of superior mesenteric artery without contacts wit lig.arcuatum from right, histologically ganglia had lobular structure with low amount of connective tissue (29%-50%). In 30% it was comprised of 2-4 large conglomerates of ganglia attached to lig.arcuatum from the bottom forming a dense circle around the vessel, decline in neuron relative number was discovered histologically. Single neurons surrounded by rough fibrous tissue were observed instead of lobules (42-94%). Correlation between structure and topography of the plexus and skeletotopy of coeliac trunk, aorta and lig.arcuatum were established which can be used to reveal "risk" groups involving neuroganglionic component in extravasal compression of coeliac trunk.
