RESUMO
The present study describes a rare variation which celiac trunk is divided into four branches instead of three, inaddition to a retro-portal pathway of the right hepatic artery. This variation was observed in a male adultcadaver. In this article, we also review the literature to make a brief discussion of the clinical and embryologicalrelevance of these variations. The identification of that kind of variations in the celiac trunk and hepatic arteriesis extremely important for surgeons and radiologists since multiple variations can lead to unexpectedcomplications.
RESUMO
Hyperbaric oxygenation consists in exposing patients to increased gas pressures while inhaling pure oxygen. It involves the use of hyperbaric chambers that can double or triple gas pressure inside them. Hyperbaric oxygenation may be useful in different clinical situations, but mostly for the treatment of decompression syndrome. In the last decades, it has been used for the management of different kinds of wounds. Hyperbaric oxygenation not only increases the delivery of oxygen to damaged tissues, but also stimulates angiogenesis, collagen synthesis, stem cell migration and local immune response. Clinical trials that have addressed the use of hyperbaric oxygenation are difficult to compare due to their heterogeneity in terms of experimental design, kind of injuries involved and assessment of outcome. Even though, most studies support the concept that hyperbaric oxygenation accelerates the healing process.
