Anatomical variations are deviations from the standard structures and morphologies of bodily arrangements, a phenomenon commonly seen in arteries and nerves. A typical axillary artery extends from the outer border of the first rib to the lower edge of the teres major before the pectoralis minor divides the axillary artery into three parts. Within existing research, several variations have been seen in the branching of the axillary artery, particularly among the second and third divisions. This case report examines and describes the anatomical differences of the second and third division of the axillary artery in a 64-year-old Caucasian female; variations were found in the second division of the axillary artery, two thoracoacromial arteries, as well as the absence of the stemming lateral thoracic artery. Within the third division of the axillary artery, the subscapular artery supplying the latissimus dorsi (two branches), subscapularis (circumflex scapular artery), and the serratus anterior (two branches) muscles were identified and distally, the axillary artery bisected into the brachial and accessory brachial arteries. A genetic mutation, environmental factors, and embryological malformations are among the hypotheses associated with these anatomical variations. From a clinical standpoint, these variations may not produce impairment though the knowledge of an individual’s distinctive arrangements would aid in preventing unnecessary complications that could arise during particular interventions.

AbstractThe median nerve is formed in the axilla by fusion of the two roots from the lateral and medial cords. The present case report describes an anomalous presentation of double formation of median nerve and its relation with axillary and brachial arteries. The median nerve was formed in two stages at different levels, first in the axilla and then in the upper arm by receiving double contribution from the lateral root of the lateral cord, which fuse with the medial root of the medial cord to form the median nerve. The formation took place medial to the axillary artery in the axilla and antero-medial to the brachial artery in the arm. Such anatomical variations and their relation with the arteries are important for the surgeons and anesthesiologists and of great academic interest to the anatomists.

BACKGROUND: Variations in the branching pattern of the axillary artery are a rule rather than an exception. The knowledge of these variations is of anatomical, radiological, and surgical interest to explain unexpected clinical signs and symptoms. OBJECTIVE: The large percentage of variations in branching pattern of axillary artery is making it worthwhile to take any anomaly into consideration. The type and frequency of these vascular variations should be well understood and documented, as increasing performance of coronary artery bypass surgery and other cardiovascular surgical procedures. The objective of this study is to observe variations in axillary artery branches in human cadavers. METHODS: We dissected 80 limbs of 40 human adult embalmed cadavers of Asian origin and we have studied the branching patterns of the axillary artery. RESULTS: We found variations in branching pattern of axillary artery in 62.5% of the limbs. Anatomical variations included: origin of lateral thoracic artery from the subscapular artery; absent thoracoacromial trunk and all its branches arose directly from the second part of the axillary artery; division of thoracoacromial trunk into deltoacromial and clavipectoral trunks, which were divided into all branches of thoracoacromial trunk; origin of subscapular, anterior circumflex humeral, posterior circumflex humeral and profunda brachii arteries from a common trunk from the third part of the axillary artery; and origin of posterior circumflex humeral artery from brachial artery in addition to third part of the axillary artery. CONCLUSIONS: The study was carried out to show important variations in the branching pattern of axillary artery, in order to orient the surgeons performing angiography, coronary bypass, and flaps in reconstructive surgeries.

During routine dissection of an approximately 50-year-old male cadaver for the undergraduate medical students at Melaka Manipal Medical College, Manipal University, Manipal, we came across a variation in branching pattern of right axillary artery. The second part of axillary artery gave rise to a common trunk which divided into the subscapular and lateral thoracic arteries. The third part of right axillary artery gave rise to anterior and posterior circumflex humeral arteries. Variations in the branching pattern of axillary artery are important for the surgeons performing interventional or diagnostic procedures in cardiovascular diseases.

Background: The maxillary artery supplies the deep structures of the face and cranium. The maxillary artery and the mandibular nerve form a clinically important relation in the infratemporal fossa. Variations of the maxillary artery may complicate dental, oral, and maxillofacial surgeries in this region. Methods: During routine academic dissection of a 91-year-old Caucasian female cadaver, the pterygoid segment of the left maxillary artery was found medial to the posterior division of the mandibular nerve in the infratemporal fossa. Results: The maxillary artery coursed superior to the point of division of the mandibular nerve and remained undivided. Conclusion: This rare unilateral variation will be of interest to anatomists and clinicians, as an understanding of anatomical variations of the maxillary artery can help decrease the risk of hemorrhage and other surgical complications. KEY WORDS: Maxillary artery, Mandibular nerve, Lateral pterygoid muscle, Infratemporal Fossa.

The Axillary artery is the continuation of the subclavian artery and is a major artery of the upper limb. During the routine dissection for Undergraduate Ayurvedic Medical Students of Sharada Ayurvedic Medical College, Yadgir, Karnataka, India, in the Department of Anatomy, we come across a variation in branching pattern of second and third part of right axillary artery in male cadaver approximately 55 years of age. The first part of axillary artery was found to be normal. In the second part of axillary artery we observed two branches, first one is thoracoacromial artery arose as usual second branch given common trunk which is further divided into lateral thoracic artery and subscapular artery. Even third part of axillary artery gave one common trunk that terminated by bifurcating into Anterior Circumflex Humeral Artery and Posterior Circumflex Humeral Artery.

During routine dissection of a male cadaver for I year MBBS students in the department of Anatomy bilateral variations in the branching pattern of Axillary artery were observed. In the present study it was observed that, on the left side, the subscapular artery which usually arises from the third part of Axillary artery was found to be originating from the second part along with the lateral thoracic artery and thoraco-acromial artery whereas anterior circumflex humeral artery and posterior circumflex humeral artery originated from the third part as usual. On the right side, the circumflex scapular artery and the Thoracodorsal artery were arising as a common trunk from the third part which is not the usual pattern. Knowing such variations is of utmost significance in performing various clinical procedures by Vascular surgeons, Radiologists, Clinical anatomists and in interventional and diagnostic procedures in cardiovascular diseases.

The Brachial artery usually begins as the continuation of the Axillary Artery at the inferior border of the Teres Major muscle and terminates by bifurcating into radial and ulnar arteries in the cubital fossa. A case of unilateral bifurcation of the artery 7.5 cm distal to the inferior border of the Teres Major muscle in the proximal half of the right arm was identified in a northern Nigerian cadaver that was dissected by medical students of Usmanu Danfodiyo University, Sokoto. The Profunda Brachii, Superior Ulnar Collateral and Inferior Ulnar Collateral arteries arose from the relatively short brachial arterial trunk. Although the documented incidence of this anatomical variation is low in Nigeria, its concomitant widespread documentation in other parts of the world makes it a sufficiently important anatomical variation of the Brachial Artery, to warrant its being taught to students of Anatomy and Medicine. The knowledge of anatomical variations of the brachial artery and its branches is also important in radiological and clinical practice.Keywords: Anatomical variation, brachial, artery, Nigeria

AbstractIntroduction: Mapping the branching patterns of the thoracoacromial artery has a particular practical importance. Familiarity with the different anatomical variations is essential for successful surgical procedures in the anterior shoulder region.Case presentation: We present an unusual anatomical variant observed during the dissection of a cadaver at the Department of Anatomy and Embryology of the “George Emil Palade” University of Medicine, Pharmacy, Science and Technology of Târgu Mureş, Romania. According to the classical description, the thoracoacromial artery originates from the second part of the axillary artery, but we observed an unusual branching variation: the thoracoacromial artery provided a subscapular branch right after its origin, then it split into a pectoral branch, the lateral thoracic artery, and a common trunk that gave a second pectoral branch and a deltoid-acromial branch. The clavicular branch was missing.Conclusions: The case we presented demonstrates that there are anatomical variations of the axillary artery system that are partially or entirely different from the classical descriptions. Our study describes a variation of the thoracoacromial artery that has not been reported so far.
