Anatomical variations in the formation, course and distribution of brachial plexus are well documented. The present report describes some rare variations with regard to relation of cords of brachial plexus, median and ulnar nerves with the third part of axillary artery and brachial artery in the left upper limb of an adult male cadaver. All three cords of brachial plexus were noted to be latera...

BACKGROUND Endothelial dysfunction associated with diabetes mellitus (DM) may influence arterial vasoreactivity after arterial stimulus, such as cannulation, and cause changes in diameter and blood flow. Despite the frequent use of arterial cannulation during anesthesia and critical care, little information is available regarding vasoreactivity of the radial and ulnar arteries and its influence...

Ulnar artery aneurysms are an exceedingly rare entity in the pediatric population and have no consistent etiologic mechanism. We present the case of a 15-year-old male with a multilocular ulnar artery aneurysm in the setting of no antecedent history of trauma, no identifiable connective tissue disorders, and no other apparent etiological factors. Furthermore, the patient's arterial palmar arch ...

Variations of the brachial plexus and median nerve relationships with axillary artery may be significant to anatomists, radiologists, anesthesiologists, surgeons. In some cases, coexistence anatomical variations nerves vessels also a source conflict between individual structures, e.g., entrapment neuropathy due atypical (superficial nerve) course artery. The presented report describes coexistin...

Variations of arterial patterns in the upper limb have represented the most common subject of vascular anatomy. Different types of artery branching pattern of the upper limb are very important for orthopedists in angiographic and microvascular surgical practice. The brachial artery (BA) is the most important vessel in the normal vascular anatomy of the upper limb. The classical pattern of the p...

Introduction The brachial plexus is a complex structure which is divided into roots, trunks, divisions and cords. The brachial plexus is formed by the union of ventral rami of C5, C6, C7, C8 and greater part of T1.These ventral rami are the roots of brachial plexus, almost equal in size but variable in their mode of junction. Ventral rami of C5 and C6 unite at the lateral border of the scalenus...

We present a patient with a failed radial coronary angioplasty as a result of bilateral brachioradial arteries, the radial arteries anomalously originating from the axillary arteries. We review the literature concerning abnormal origins of the radial artery and propose the left ulnar artery as optimal access of choice in cases with a right brachioradial artery of relatively small size in its pr...

The transradial approach is safe and effective for coronary procedures. However, its use may be compromised in cases of variations in radial artery anatomy, spasms, and negative Allen's test. The transulnar approach emerges as a viable alternative to transradial approach. We report on a patient who underwent primary angioplasty via ulnar artery without ischemic hand complications despite prior ...
