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.
The median nerve and coracobrachialis muscle lie laterally to the brachial artery at its proximal aspect whereas the medial cutaneous nerve of the forearm and the ulnar nerve lie medially to the artery proximally. At the distal aspect of the brachial artery, the basilic vein and median nerve lie medially. Two venae comitantes, or accompanying veins, run with the brachial artery, and are connected together by transverse and oblique branches.
