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.

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.

Introduction: Conventional knowledge of the brachial artery, the principal artery of the upper limb & its branches has played a major role in vascular surgeries. Literature along with various cadaveric & clinical studies suggest that brachial artery vary widely in origin, course and branching pattern. The great variability of this arterial pattern may be attributed to the failure of regression of some paths of embryonic arterial trunks. Anatomical knowledge of this principal artery and its variations has many clinical implications especially in surgeries related to orthopedic and vascular re-constructive procedures. MATERIALS AND METHODS: The present study was conducted on 56 upper limbs of different age group and sex (19 Male and 9 Female) The brachial arteries were identified and branching pattern and relations of the brachial artery with brachial plexus in arm was observed and presence or absence of variations were documented. Results: Out of 56 upper limbs studies, 53 (94.64%) limbs showed normal morphological pattern of brachial artery, 3 (5.35%) limbs showed superficial brachial artery, 1 limb (1.78%) showed tortuous and SBA with trifurcation into radial artery, ulnar artery and common interosseous artery in the cubital fossa. Conclusion: The study of Brachial artery and variation in its course and branching pattern is clinically important for surgeons, ortho-paedicians operating on the supracondylar fracture of humerus and radiologists performing angiographic studies on the upper limb. KEY WORDS: Common Interosseous Artery, Median Nerve, Superficial Brachial Artery, Trifurcation, Ulnar Artery.

Introduction Bilateral unusual course of the median nerve accompanied with variations of the brachial artery branching pattern are uncommon. Materials and Methods During the routine educational dissection of an upper limb, an interesting neurovascular variation was found in a 45-year-old male cadaver. Results We found a bilateral unusual and variant course of the median nerve in the arm region. The right median nerve, after formation, descended from the medial to the brachial artery, crossed the brachial artery anteriorly from medial to lateral, then inferiorly and lied medially to the distal third of the brachial artery, while the left median nerve ran medial to the brachial artery, passing anteriorly from medial to lateral, and, at the distal end of the arm, it buried itself in the brachialis muscle. Another set of findings were absence of the superior and inferior ulnar collateral arteries, superficial ulnar artery in the forearm and common interosseus artery originated from radial artery. Conclusion These types of compound neurovascular variations are of great importance in orthopedic, vascular, reconstructive surgeries and even in routine nursing care.

Superficial Ulnar Artery

The principal arteries of the upper limb show a wide range of variation that is of considerable interest to orthopedic surgeons, plastic surgeons, radiologists and anatomists. We present here a case of superficial ulnar artery found during the routine dissection of right upper limb of a 50-year-old male cadaver. The superficial ulnar artery originated from the brachial artery, crossed the median nerve anteriorly and ran lateral to this nerve and the brachial artery. The superficial ulnar artery in the arm gave rise to a narrow muscular branch to the biceps brachii. At the elbow level the artery ran superficial to the bicipital aponeurosis where it was crossed by the median cubital vein. It then ran downward and medially superficial to the forearm flexor muscles, and then downward to enter the hand. At the palm, it formed the superficial and deep palmar arches together with the branches of the radial artery. The presence of a superficial ulnar artery is clinically important when raising forearm flaps in reconstructive surgery. The embryology and clinical significance of the variation are discussed.

AbstractMandibular nerve is a branch of Trigeminal nerve which gives off Lingual, Inferior alveolar, Auriculotemporal, Buccal branch and motor branches to muscles of mastication. Anatomical variations related to mandibular nerve and its branches are of great importance to Oral maxillofacial surgeons and Dentists. During routine cadaveric dissection of infratemporal fossa of an adult male in the Institute of Anatomy, Madurai Medical College, variations in the branching pattern of mandibular nerve and an unusual course of lingual nerve were found on the left side. Such anatomical variations of mandibular nerve and its branches are of clinical significance during dental procedures and maxillofacial surgeries.

AbstractDuring routine dissection of upper limb, a variation in the origin of radial artery was observed in a female cadaver of about 60 years. The radial artery is usually a smaller terminal branch of the brachial artery in the forearm. On the right side of the cadaver the radial artery was found to originate from second part of the axillary artery, whereas on the left side the origin of radial artery was found to be normal. This variant of radial artery has been rarely documented in literature. Accurate anatomy of radial artery and its variations have definite diagnostic, interventional, and surgical significance.

Background: Variations in upper limb arteries have been frequently observed. Accurate knowledge of muscular and neurovascular variations is important for both surgeons and radiologists, which may prevent diagnostic errors.Methods: A study was done to note the variations in the termination of brachial artery in relation to the level of termination and the terminal branches. A total of 60 upper limbs (33 Right, 27 Left) were studied. The level of termination of brachial artery was identified based on the distance between the intercondylar line and the point of termination. The classic textbook description of brachial artery bifurcating into radial and ulnar arteries, 1 cm distal to elbow joint (ICL) was taken as normal.Results: A high origin of radial artery was noted in 11.67% of cases. Variations in the origin and relationship of median nerve to brachial artery, radial artery and ulnar artery was seen in 4 cases.Conclusions: Due to higher incidence of anatomical variations of arteries of the upper limb, prior anatomical knowledge of anomalies is of great clinical significance to vascular surgeons, orthopaedicians and radiologists performing angiographic studies.

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.

AbstractA detailed description of the vascular pattern of upper limbs especially their variations in their origin, course and branching pattern is of utmost importance anatomically in general and clinically in particular. These variations have drawn attention of surgeons, physicians, radiologist and interventionists due to the advanced surgical procedures practicd in vascular surgeries, plastic (reconstructive) surgeries and also for diagnostic and therapeutic approaches. 50 cadavers (100 upper limbs) were used for the study, which were dissected as the part of routine dissection for teaching undergraduate students at our institution. Length of the normal and variant arteries with mean, standard deviation, 'p' and 't' values are noted in each of the limbs. The following variations are observed - i) high division of brachial artery ii) higher origin of profunda brachii artery, iii) high origin of radial artery, iv) absence of common interosseous artery. The variations are of particular importance to the surgeons operating in the area, especially for those involved in vascular reconstructive surgeries. So it is prudent to do pre-operative studies of the brachial and antebrachial arteries and their branching patterns, to prevent possible complications post operatively.
