ABSTRACT
Background: Variations of the arteries, nerves and muscles of the upper limb have both clinical and surgicalimportance. The superficial brachial artery origination from the third part of the axillary artery, communicationsbetween the musculocutaneous and median nerves, variant formation of the brachial plexus, origination of theProfunda brachii artery from the posterior circumflex humeral artery have been well documented. We describehere the other variations in the upper limbs of a male cadaver.Case Report: During our routine dissection studies on a 50year old male cadaver we encountered variations inRight upper limb.Observations: In this case we observed the axillary artery gives two terminal branches the first was the superficialbrachial artery and the second was a common trunk for the sub scapular,brachial, posterior circumflex humeral and anterior circumflex humeral arteries. Superficial brachial arterygive Radial and Ulnar arteries. Variant formations of the brachial plexus i.e., medial root of median nerveoriginate from both lateral and medial cord.Conclusion: We think that such variations should be kept in mind during surgical and diagnostic procedures.Variation in the brachial plexus medial root of median nerve originate from both lateral and medial cord mightbe of significance in diagnostic clinical neurophysiology.
ABSTRACT
Abstracts: Variations of the axillary artery have been frequently observed during routine anatomy dissection classes. These variations of vascular system are of considerable significance for surgical and radiological procedures. Accurate knowledge of these variations is desirable as well as essential as they may be mistaken for veins that may lead to formation of gangrene and even loss of hand during surgical procedures. Reported here is one such case of A unilateral superficial brachial artery with a high origin of Profunda Brachii artery (PBA) as observed during routine dissection class of medical students at Rohilkhand Medical College, Bareilly, India.
ABSTRACT
The principal arteries of the upper limb show a wide range of variations that are of considerable interest to orthopedic surgeons, plastic surgeons, radiologists and anatomists. We present here a case of bilateral superficial brachial artery found during the routine dissection of the upper limbs of a 50-year-old female cadaver. In both the limbs, the third part of the axillary artery divided into superficial brachial and deep brachial arteries; denominated according to their relation to the median nerve. The superficial brachial artery continued in the arm without giving any branches and ended in the cubital fossa dividing into radial and ulnar arteries. The deep brachial artery gave rise to anterior circumflex humeral, posterior circumflex humeral and profunda brachii arteries. Earlier superficial brachial artery has been reported with a prevalence rate varying from 0.2% to 25% but bilateral variation is extremely rare. The great variability of this arterial pattern may be attributed to the failure of regression of some paths of the embryonic arterial trunks.1 The embryological and clinical significance of this variant are also discussed in detail.
ABSTRACT
The vascular anatomy of the human upper limb which is man’s important earning tool, is a complex and challenging area. The arterial supply of the upper limb is mainly maintained by brachial artery through its branches. Recent progress in vascular surgery has engendered a need for precise knowledge of the frequency of anatomical variations in the branching pattern of axillary artery. Upperlimb injuries are the most frequent occupational accidents. Awareness of variations in the anatomy of brachial artery and its branches is important to avoid serious complications while treating the cases of arterio-venous fistulae, aneurysms and abscess drainage in the region of axilla, arm and cubital fossa. The present study was undertaken on 54 upper limbs of both sexes from embalmed adult human cadavers . The specimens were studied by detailed dissection method. In the present study, 59.3% of specimens showed variations of axillary artery. Better anatomical knowledge about the branches of brachial artery and their variations are important for surgeons, physicians, radiologists and interventionists, because based on anatomical study, new diagnostic and therapeutic approaches can be proposed.
ABSTRACT
During an ordinary dissection, a cadaver showed a bilateral anomalous origin of the deep brachial artery, where this vessel appeared like a branching of the subscapular artery with common trunk, which included the posterior circumflex humeral artery. The course and distribution of the deep brachial artery in the back compartment were relatively consistent with previous reports. Arterial variations can be damaged through iatrogenic means if not properly documented. The knowledge of this case is very important in clinical medicine and in surgeries in this compartment to prevent any injury.
Durante dissecação em prática usual, um cadáver apresentou origem anômala da artéria braquial profunda, na qual este vaso apareceu como um ramo da artéria subescapular com um tronco comum, que incluiu a artéria circunflexa posterior do úmero. O curso e a distribuição da artéria braquial profunda no compartimento posterior foram relativamente coincidentes com relatos prévios. Variações arteriais podem ser danificadas de maneira iatrogênica se não forem adequadamente documentadas. O conhecimento desse caso é muito importante na prática clínica e em cirurgias nesse compartimento para prevenção de qualquer injúria.

En este estudio se trata de observar la variabilidad del origen y morfología de la arteria braquial profunda. Se utilizaron 14 cadáveres, a los cuáles se les midió el largo y diámetro de la Arteria Braquial Profunda antes de su bifurcación en Arteria Colateral Radial y Colateral Media en ambos brazos. El 21,4 por ciento presentó el origen de la Arteria junto con ramas musculares, el 14,3 por ciento de manera bilateral un origen común de la Arteria Braquial Profunda y la Arteria Circunfleja Humeral Posterior, el 7,2 por ciento una bifurcación temprana de la Arteria Braquial en Arterial Radial y Ulnar a nivel del tercio proximal del antebrazo y el 7,2 por ciento la misma variación a nivel del tercio medio. La longitud y diámetro de la Arteria en el estudio en promedio fue de 84,78 mm con un diámetro de 1,66 mm en la izquierda y de 83,26 mm con un diámetro de 1,68 mm de la derecha, las diferencias presentadas no son estadísticamente significativas. El conocimiento de las diferencias anatómicas de importancia en la práctica clínica y quirúrgica...
