Variations in axillary artery branching pattern can lead to iatrogenic injuries during invasive procedures. Knowledge of the same is critical to prevent such events. Multiple bilateral variations were observed in the branching pattern of axillary artery. These variations were noted in a female cadaver, during routine undergraduate dissection in September 2019 in Lady Hardinge Medical College, New Delhi. On the left side, an anomalous branch running with the medial pectoral nerve was found. A common stem arising from the 2nd part of left axillary artery divided to give the lateral thoracic artery, the subscapular artery and an alar artery. Another alar branch arose from the left subscapular artery before it bifurcated into thoraco-dorsal and circumflex scapular arteries. The right axillary artery gave an aberrant branch proximal to the lateral thoracic artery. A common trunk arising from the 2nd part of right axillary branched out to give the posterior circumflex humeral artery, the subscapular artery and an alar artery. The brachial artery divided 13.5 cm proximal to the intercondylar line of humerus on the left and 14.4 cm on the right side. On both sides, the ulnar artery arose proximally and the radial and common inter-osseous arteries continued as a common trunk and divided distally. This case study reports multiple bilateral axillary artery anomalies and complements to the existing knowledge of vascular anomalies. Comprehensive knowledge of these variations is essential from anatomical, radiological and surgical point of view. During surgeries involving axillary and pectoral group of lymph nodes, such variations should be kept in mind.

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.

Abstract Background Variations in the upper limb arterial pattern are commonplace and necessitate complete familiarity for successful surgical and interventional procedures. Variance in the vascular tree may involve any part of the axis artery of the upper limb, including the axillary artery and brachial artery or its branches, in the form of radial and ulnar arteries, which eventually supply the hand via anastomosing arches. Objectives To study the peculiarities of the arterial pattern of the upper limb and to correlate them with embryological development. Methods The entire arterial branching of forty-two upper limbs of formalin fixed adult human cadavers was examined during routine dissection for educational purposes, conducted over a 3-year period in the Department of Anatomy, Lady Hardinge Medical College, New Delhi. Results The study found: 1) One case in which a common trunk arose from the third part of the axillary artery, which immediately splayed into four branches (2.4%); 2) High division of the brachial artery into ulnar and radial arteries, in 3 cases (7.1%); 3) Pentafurcation of the brachial artery into ulnar, interosseus, radial, and radial recurrent arteries and a muscular twig to the brachioradialis in 1/42 cases (2.4%); 4) Incomplete Superficial Palmar arch in 3/42 cases (7.1%); and 5) Presence of a median artery in 2/42 case(4.8%) Conclusions This study observed and described the varied arterial patterns of the upper limb and identified the various anomalous patterns, supplementing the surgeon’s armamentarium in various surgical procedures, thereby helping to prevent complications or failures of reconstructive surgeries, bypass angiography, and many similar procedures.

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.

Brachial artery in arm is commonly used for percutaneous arterial catheterization, angiography, vascular flaps for reconstructive surgeries, and can be injured in fractures of arm or elbow region. Knowledge of variations in branching pattern is must for all clinicians and especially for vascular and orthopaedic surgeons to avoid complications like haemorrhage, ischemia and necrosis during various surgical procedures. This study was done to observe variations in branching pattern of brachial artery in cadavers and its clinical applications. The study was conducted on eighty upper limbs of 40 cadavers (30 males and 10 females) of age group 50-70 years in the Dept of Anatomy, R.N.T. Medical College, Udaipur (Raj). In 30 cadavers branching pattern of brachial artery was normal. In 10 cadavers either unilaterally or bilaterally variable branching pattern was noticed in the form of (1) Absence of profunda brachial artery (2) Origin of Profunda brachii artery from axillary artery (3) Termination of brachial artery i.e. in the middle of arm into radial and ulnar artery (4) Termination of brachial artery in arm into medial and lateral branches continuing distally as radial and ulnar artery respectively. Genetic predisposition, chemical factors or hemodynamic forces can be the reasons for arterial variations in the upper limb.

During routine undergraduate dissection in the upper extremities of a 65 years old male cadaver in the department of Anatomy at Dr. PSIMS & RF, coexistence of muscular and neurovascular variants were identified .Muscular variations included presence of additional head(third) of biceps brachii in the left arm, accompanied with medially positioned median nerve in relation to brachial artery bilaterally . Teres minor muscle was not identified and the origin of long head of triceps brachii extended upto the lateral border of scapula on the left side. Both the medial cutaneous nerves of arm and forearm arouse from a single trunk bilaterally. In the right limb the axillary artery showed only four branches instead of six branches, with common trunk for thoraco-acromial and lateral thoracic artery and common trunk for subscapular and posterior circumflex humeral artery. Knowledge of coexistence of these variations would of profound importance surgically and clinically, especially in limb injuries and surgical repairs.

AbstractDuring routine dissection of a cadaver alloted to the undergraduate students in the department of anatomy in SN Medical College, Bagalkot, the authors found multiple variations in the branching pattern of brachial, ulnar and radial arteries. There was high division of brachial artery into ulnar and radial arteries. The profunda brachii originated from brachial artery as usual while superior and inferior ulnar collateral arteries originated from ulnar artery. The radial artery gave origin to common interosseous artery which further divided into anterior and posterior interosseous arteries. All the three arteries i.e. brachial, ulnar and radial were considered as superficial arteries as they were superficial throughout the course. These observations of vascular anomalies are of clinical significance to vascular and plastic surgeons.

Context: The kidney is a highly vascular organ in the human body. The aim of the present study was to see the variations in perihilar branching pattern and morphology of the main renal arteries in a Bangladeshi population based on autopsy.Methods: This cross-sectional, descriptive study was done in the Department of Anatomy, Dhaka Medical College, Dhaka, from July 2008 to June 2009, based on collection of 140 post mortem human kidneys from 70 unclaimed dead bodies which were in the morgue. All the samples were divided into three age-groups: A (10-19 years), B (20-39 years) and C (40-59 years). Morphological examination was done to identify main renal arteries and accessory renal arteries with their sites of origin and perihilar branching pattern of the renal arteries as well. The length of the renal artery was measured by using a measuring tape. Besides, renal angiography was done to see the intrarenal branching pattern.Results: The length of the right and left renal arteries were found 3.09±0.08 cm and 2.09±0.09 cm; 3.48±0.17 cm and 2.34±0.17 cm; 3.88±0.17 cm and 2.81±0.16 cm in group A, B and C respectively. The length of the right renal artery was found greater than of the left (P<0.001) in all age-groups. Besides, age related changes were also found in the length of the renal arteries (P<0.001). Accessory renal arteries were present in the right side in 33.4%, 23.35 and 33.3% specimens in group A, B and C respectively, while in the left side, in 59.7%, 27.9% and 13.4% in group A, B and C respectively. The number of anterior divisions of the both renal arteries were 2 in 8.3%, 3 in 12.5% and 4 in 79.2% specimens in group A, while in group B, 2 in 7%, 3 in 17.4% and 4 in 75.6% specimens, and in group C, 2 in 3.3%, 3 in 3.3% and 4 in 93.3% specimens. Number of posterior division was found only 1 in all the groups. Renal angiography revealed intrarenal branching pattern which showed segmental arteries divided into several lobar arteries and interlobar arteries.J Dhaka Medical College, Vol. 24, No.1, April, 2015, Page 12-16

Arterial Anomalies

Variations in the branching pattern of axillary artery are observed by many anatomists all over the world. A unique bilateral variation in the axillary artery was observed during the routine dissection of the upper limbs on an approximately 65 year old male cadaver. An abnormal communicative channel was observed between lateral thoracic artery and anterior circumflex humeral artery. It passed between the two roots of median nerve. Arterial anomalies in the upper limb are due to defective remodelling of vascular plexus of the upper limb bud during embryogenesis. Knowledge of variations in axillary artery is quintessential for surgeons, radiologists and anaesthesiologists to avoid treacherous complications during procedures.
