Seroma â Definition, Symptoms, Fluid, Treatment, Types. A Seroma is a collection of serous fluid that develops after surgery or any blunt injury. Serous fluid is the fluid compartment of blood that seeps out when blood vessels are injured or ruptured during operation. Inflammation on the surgical site also increases the capillary permeability, thus increasing the flow of plasma from blood vessels into the interstitial spaces (spaces between cells).
A detailed description of the anatomical variations of the median nerve in the carpal tunnel, including the bifid median nerve, was previously reported. The bifid median nerve is a cause of secondary carpal tunnel syndrome due to its relatively higher cross-sectional area compared with a nonbifid median nerve. Magnetic resonance imaging (MRI) and ultrasound can be obtained to show bifid median nerves, helping surgeons avoid potential surgical hazards.
Left The median arcuate ligament is normally several millimeters to centimeters superior to the origin of the celiac artery. Right In MALS, the ligament is anterior, rather than superior, to the celiac artery, resulting in compression of the vessel and a characteristic hook-shaped contour.eliac artery compression was first observed by Benjamin Lipshutz in 1917. MALS was first described by Pekka-Tapani Harjola in 1963 and subsequently by J. David Dunbar and Samuel Marable in 1965. It has also been called Harjola-Marable syndrome and Marable syndrome.
