Similar conditions are achieved in the adult by derotating the bowel via the Cattell-Braasch maneuver. However, possible preparational bias might compromise the resulting topography.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Case presentation<\/jats:title>\n            <jats:p>We present a case of atypical malrotation of the bowel in a cadaver study using a 96-year-old Caucasian male specimen with incidental finding of the pathology post mortem with no known surgical intervention in the abdomen during his lifetime. We compare the topography and abdominal layers with the anatomy of a 98-year-old Caucasian female specimen where the Cattell-Braasch maneuver was used to revert the embryologic development.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>Reverting the embryologic development in the adult via Cattell-Braasch maneuver enables to mirror inherent malrotation and reestablishes the position of the bowel prior to its rotation. The Cattell-Braasch maneuver is further validated in this study by showing that it is able to demonstrate essential layers for surgical interventions without damaging their integrity. Atypical malrotation unmasks those fascial border-like layers, which are often hidden due to adhesions and fusing of tissue during the usual embryologic development. Developmental defects present a chance to explore essential surgical layers that are otherwise masked by artifacts due to fusion of layers of connective tissue.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/s13256-024-04869-6","type":"journal-article","created":{"date-parts":[[2024,11,12]],"date-time":"2024-11-12T05:01:30Z","timestamp":1731387690000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Validating the Cattell-Braasch maneuver with a case of inherent atypical malrotation of the bowel: a case report"],"prefix":"10.1186","volume":"18","author":[{"given":"Athanasios","family":"Alvanos","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Junk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ingo","family":"Bechmann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanno","family":"Steinke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,11,12]]},"reference":[{"issue":"4","key":"4869_CR1","doi-asserted-by":"publisher","first-page":"275","DOI":"10.1053\/j.sempedsurg.2003.08.009","volume":"12","author":"D Kluth","year":"2003","unstructured":"Kluth D, Jaeschke-Melli S, Fiegel H.
