In the compression cases of the celiac trunk by the arcuate ligament (Dreze et al.; Joubaud et al.) and associated SMA (Houssin et al.) when the very dense fibronervous envelope formed by nervous and lymphatic ramifications involving both arteries and celiac trunk branches was sectioned, an arciform
bridge, considered to be the diaphragmatic arcuate ligament was observed crossing the celiac trunk.
(1967) observed intrasurgically that if the section of the fibrotic ganglion of the celiac plexus is performed, the pulsations of the celiac trunk and its branches do not return to normal, being necessary decompression of the celiac trunk by sectioning arciform
fibers of the diaphragm, which also exert compression.
The most common sites of involvement are the cheeks, forehead, upper lip, nose, chin and V area of the neck, rarely in the neck and forearms.The large, spreading, pigmented macules often have polycyclic or arciform
