It is commonly held that the caudal mesenteric artery (CaMA, or inferior mesenteric artery in humans) arises in the same manner as the celiac and cranial mesenteric artery (CrMA, or superior mesenteric artery in humans), i.e., from the remodeling of the vitelline system of arteries that surrounds and supports the yolk sac. Conflicting evidence about the precise manner in which the CaMA arises w...

Rare vascular anomalies were observed postmortem in a Japanese female (60-yearold). 1) The common hepatic artery arose from the superior mesenteric artery, ascended on the anterior surface of the pancreas, where the right gastro-epiploic and right gastric arteries branched, and continued as a normally-positioned proper hepatic artery. 2) Superior to the inferior phrenic arteries and along the c...

Color Doppler ultrasonography was used to compare blood flow characteristics in the caudal artery of heifers fed diets with endophyte (Neotyphodium coenophialum) infected (E+) or noninfected (E-) tall fescue seed. Eighteen crossbred (Angus x Brangus) heifers were assigned to 6 pens and were fed chopped alfalfa hay for 5 d and chopped alfalfa hay plus a concentrate that contained E-tall fescue s...

The anterior interosseous nerve is a branch of the median nerve. It arises from the median nerve just distal to the antecubital fossa, about 5.5 cm distal to the medial epicondyle of the humerus. [2] It passes along the interosseous membrane between the ulna and radius. It terminates in the pronator quadratus muscle around the level of the wrist. It is largely a motor nerve. It supplies the fle...

OBJECTIVE To investigate the spatial pattern of lesion dispersion in posterior interosseous neuropathy syndrome (PINS) by high-resolution magnetic resonance neurography. METHODS This prospective study was approved by the local ethics committee and written informed consent was obtained from all patients. In 19 patients with PINS and 20 healthy controls, a standardized magnetic resonance neurog...

OBJECTIVE We sought to determine lesion sites and spatial lesion patterns in spontaneous anterior interosseous nerve syndrome (AINS) with high-resolution magnetic resonance neurography (MRN). METHODS In 20 patients with AINS and 20 age- and sex-matched controls, MRN of median nerve fascicles was performed at 3T with large longitudinal anatomical coverage (upper arm/elbow/forearm): 135 contigu...

STUDY DESIGN A retrospective study using 27 contrast-enhanced multi-planar computed tomography scans of subjects with lumbar scoliosis. OBJECTIVE To assess the risk of injury of lumbar segmental arteries during transpsoas approach in patients with lumbar scoliosis. SUMMARY OF BACKGROUND DATA Although lumbar interbody fusion using big intervertebral cage through transpsoas approach has a big...

Lipomas are extremely common benign soft tissue tumors that are usually subcutaneous and asymptomatic. However, an intramuscular lipoma, occurring adjacent to the proximal radius, may easily cause paralysis of the posterior interosseous nerve because of a specific anatomical relationship of these structures in that area. In this report, we describe an unusual case of a 48-year-old-woman with a ...
