Highlights
Colonic volvulus represents the leading cause of colonic obstruction in sub-Saharan Africa.
The sigmoid colon is the primary site of volvulus while the transverse colon is a rare condition.
The synchronous occurrence of a sigmoid colon and transverse colon volvulus is exceptional.
The dual location of strangulation makes it a major surgical emergency with a high risk of gangrene and septic shock.
The literature concerning its description is sparse and the treatment options are poorly codified.
Introduction: The knowledge of different anatomical variations of the terminal branches of the thoraco-acromial artery is inseparable from any integumentary surgery of the anterior region of the shoulder. It is especially the case when performing surgery of reconstruction flaps of this region, whose use is increasing in recent years. The purpose of our work was to report the modalities of birth and terminal division of the thoracoacromial artery. Material and methods: We performed a direct and selective injection of 24 thoracoacromial arteries on cadavers preserved in a low-formalin solution rich in glycerin. The injected solution was made of a mixture of methylene blue and gelatin. Cadaveric dissection was then used to study the location, number, and path of the terminal branches of the thoracoacromial artery. Results: In the thickness of the cellulo-fatty tissue, the thoracoacromial artery gave at least two and at most four terminal branches: two bulky and constant branches (the deltoid and pectoral branches) and two small and inconstant branches (the acromial and clavicular branches). However, anatomical variations were also found in the path and localization of each terminal branch: thus the deltoid and pectoral branches had a vertical downward or oblique path. Conclusion: The anatomical variations observed on the terminal branches of the thoracoacromial artery can compromise any surgery of the anterior shoulder area of the integument. These variations should be better known by surgeons.
IntroductionConnaitre les dimensions normales de l'oreille externe constitue un pré-requis en chirurgie. Le but de ce travail est de déterminer les valeurs moyennes des différentes mesures morphométriques des oreilles gauches et droites dans notre population d’étude.MéthodesNotre groupe d’étude était constitué de 100 sujets adultes jeunes (50 femmes et 50 hommes) âgés de 18 à 25 ans, et exempts de traumatismes ou d'anomalies congénitale de l'oreille externe. Les différentes mesures répertoriées étaient représentées par: la hauteur totale de l'oreille, la largeur totale de l'oreille, la hauteur lobulaire, la largeur lobulaire, la distance tragus - anti-hélix, la distance tragus - hélix, ainsi que la projection de l'oreille.RésultatsL’âge moyen de notre population d’étude était de 22 ans. La hauteur totale de l'oreille était respectivement de 61,6 et 60,3 mm chez les sujets de sexe masculin et féminin. La largeur totale retrouvée était respectivement de 32,5 et 30,8 mm. Pour toutes les distances mesurées, nous retrouvions des différences entre hommes et femmes, ainsi que d'un coté à l'autre.ConclusionPour le clinicien, il est important de prendre en compte les mesures morphométriques de l'oreille externe non seulement dans un but diagnostic, mais également pour reproduire lors de sa reconstruction une oreille anatomiquement correcte.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
