Bilateral High Division of Brachial Artery: A Case Report and Clinical Significance in Ayurvedic and Modern Medical Practice

The brachial artery is a major artery of arm and continuation of the axillary artery. It begins at the lower border of the teres major muscle and ends at the level of the neck of the radius in deeper part of cubital fossa by dividing into radial and ulnar arteries. The brachial artery variations were observed in its course, branching pattern and division. Higher division of brachial artery is one of the common variations ranging from 15% to 20% of population. The course, termination and precise knowledge of variations of Brachial Artery is an important aspect in the clinical practice of Physician, Vascular surgeons, and Radiologist.

Unilateral higher division of brachial artery

Arterial variations are common in upper extremity. The present article describes a case of higher division of brachial artery. Higher division of brachial artery occurred above the level of insertion of coracobrachialis muscle. Further, the brachial artery proper continues lateral to median nerve in the cubital fossa and divides into radial and ulnar artery at the level of neck of radius. Higher division of brachial artery continues downward and medially, medial to the median nerve in cubital fossa, forming the superficial palmar arch in the palm. Knowledge of such variation is extremely important, especially for the limb surgeons (for carrying out surgeries in arm, creating arteriovenous fistulas for dialysis), routine blood pressure measurements, radiographic imaging, and interventionists. The relevant topics of embryology, anatomy, and its clinical importance have been discussed in the literature review. The purpose of this article is to highlight the need for the awareness of the potential existence of such anatomical variation and how it can be preoperatively detected by color Doppler imaging, which would help the surgeons and clinicians to plan out surgery and therapeutic interventions.

Unilateral high division of brachial artery

AbstractArterial variations in the arm are of great clinical importance as this area is commonly involved in many surgical and invasive procedures. During dissection, we observed in the right upper limb a variation in the division and branching pattern of brachial artery in a female cadaver. The short segmented brachial artery divided about 6 cms. above the line joining the epicondyles of the humerus, but not in the cubital fossa. The course of the two divisions in the forearm is normal. Knowledge of these variation patterns is useful during surgeries.

Variations in the branching pattern of brachial, ulnar and radial arteries

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.

UNILATERAL HIGH DIVISION OF BRACHIAL ARTERY: A CASE REPORT AND LITERATURE REVIEW

AbstractThere are many articles reporting anomalies of various blood vessels of upper extremity. In the present article, we are reporting a case of high division of brachial artery into medial and lateral branches, 9.5 cm distal to the lower border of teres major muscle. It was also observed that the two branches are crossing over near the lower part of front of arm and the lateral branch continued into the cubital fossa and trifurcated at the proximal border of pronator teres muscle. We have discussed the anatomy, embryological basis, and clinical implications of these variations along with relevant literature review. The importance of knowledge about these variations in therapeutic and diagnostic interventions is discussed.

A study of anatomical variations of median nerve in human cadavers

Comprehensive knowledge pertaining to anatomical variations of median nerve is extremely important in clinical and surgical procedures so as to avoid injury to it. The objectives of the study were to know about the variations of median nerve in its formation, course, and distribution in arm. Dissection method was employed and 50 upper limbs were studied for anatomical variations of median nerve obtained from the department of Anatomy. Median nerve was formed by two roots in 37(74%) and by three roots in 13 (26%) specimens. It was formed in axilla in 32(64%), in upper third of arm in 10 (20%), middle third of arm in 6 (12%) and lower third of arm in 2 (4%) specimens. In one specimen high division of brachial artery in the middle third of the arm was observed along with formation of median nerve at the same level. Formation of median nerve was lateral to axillary artery in 42 (84%), anterior to axillary artery in 5 (10%), medial to axillary artery in 3 (6%) specimens. Median nerve coursed lateral to brachial artery in 47 (94%), medial to brachial artery in 3 (6%) specimens Median nerve was supplying flexor muscles of arm in 6 (12%) specimens. In two of these six specimens there were concomitant neurovascular variations as well. The present study may provide additional information as such neurovascular variations encountered here are important to be noted during surgical procedures as these are more prone to iatrogenic injuries.

Variations in the arteries of the upper limb are commonly seen. Most of these variations are seen as variant division of axillary artery and as high origin of radial or ulnar artery. In the present case a higher division of brachial artery was seen, with the artery dividing in the arm just distal to teres major muscle into its terminal branches, the radial artery laterally and ulnar artery medially, the artery had passed superficial to the median nerve before its division. The other branches, profunda brachii and superior ulnar collateral arteries arose from brachial artery whereas the inferior ulnar collateral artery arose from the ulnar artery. Knowledge of such variations is important in view of their clinical significance and they need to be considered prior to surgical procedures.

Higher bifurcation of brachial artery with superficial course of radial artery in forearm: A study report

Background: Normally brachial artery divides into its terminal branches namely radial and ulnar arteries at the neck of the radius in the cubital fossa and these are the main arteries responsible for the irrigation of the forearm. In the present study we found higher division of brachial artery into radial and ulnar arteries with superficial course of radial artery unilaterally during routine dissection for MBBS student. Accurate information regarding these variations is important during vascular and re-constructive surgery and also in evaluation of angiographic images. Aims & Objective: The altered anatomy of the blood vessels may make them more vulnerable to trauma and to haemorrhage but at the same time more accessible for cannulation. Our aim is to report the occurrence of the higher division of brachial artery with superficial course of radial artery in a sample of western Indian population. Material and Methods: A prospective evaluation was conducted on cadavers at various Medical Colleges, in Gujarat. The upper limbs of cadavers were dissected and observed for any variation in the course of brachial artery and its terminal branches radial and ulnar arteries. Results: A total of 96 arms of 48 subjects were studied. In three upper limbs we found higher division of brachial artery with superficial course of radial artery. The variant was present unilaterally in left upper limb of three males (6.25%, n = 48). Conclusion: Anomalies in origin and course of principal arteries have practical importance for orthopaedicians, radiologists and vascular surgeons. Awareness of incidence of this variation is necessary to avoid complication during pre-operative procedure or surgeries in the upper limb.

An Anatomical Study of Primary Pattern of Arteries of Upper Limb With Relevance to Their Variations

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.

Unilateral High Division of Brachial Artery with Common Trunk of Origin for Radial and Profunda Brachii Arteries

Variations in the arterial pattern of upper limb are of common observation during cadaveric dissections, surgical procedures and radiological imaging. The pattern of arterial variations and their relationship with neighboring structures is of clinical importance. Most of the arterial variations in the upper limb are of radial and ulnar arteries. Brachial artery variations and mid arm variations are rare. During routine dissection of an adult cadaver high bifurcation of brachial artery into a larger ulnar artery and a short trunk that further subdivided into profunda brachii and superficial radial arteries was observed in the right upper limb.

Unusual insertion of the coracobrachialis muscle to the brachial fascia associated with high division of brachial artery

Anatomical variations of the coracobrachialis muscle (CBM) are common. We detected an abnormal form of the CBM of the left arm during human cadaver dissection. The CBM originated from the tip of the coracoid process of the scapula and divided into muscular and musculo-aponeurotic bellies. The muscular belly inserted into the middle of the anteromedial surface of the humerus, which is the normal anatomic insertion point of the CBM. The musculo-aponeurotic belly inserted into the medial intermuscular septum as well as the brachial fascia, creating a tunnel for the passage of the brachial artery. Inside the tunnel, the brachial artery bifurcated into the radial and ulnar arteries. No abnormality of the CBM, the brachial artery, or the median nerve was detected in the contralateral arm. The phylogenic, ontogenic, functional, and clinical importance of this variant muscle is described. Knowledge of such variations is of considerable importance during invasive and non-invasive investigative procedures or orthopedic, reconstructive, or surgical procedures.
