Radial Artery: Anatomical Variations at Wrist and Clinical Significance
International Journal of Anatomy and Research, 2019
Background: Knowledge regarding the course and termination of the radial artery before harvesting it for coronary artery bypass graft surgery (CABGS) is important. The brachial artery terminates at the neck of radius into radial and ulnar arteries. Purpose of the study: To know the various patterns of anomalous division ofthe radial artery. Methods: The study included 50 upper limb specimens from the Department of Anatomy, Sree Narayana Institute of Medical Sciences, Ernakulam. The specimens were fixed with 10% formalin solution and the radial artery was exposed from its origin till termination and observations were noted down. Results: The present study revealed that, radial artery usually was arising from brachial artery at the level of neck of radius. The variants observed included high bifurcation of brachial artery, division of radial artery into palmar and dorsal branches in the forearm and anomalous course of radial artery in the region of anatomical snuff box. Conclusion: The present study has revealed the anomalous division and course of radial artery around the wrist and anatomical snuff box and the knowledge of such anomalous course is important for diagnostic, interventional and surgical procedures.
Clinically-relevant Variations in the Origin and Course of the Radial Artery
Negah Institute for Scientific Communication, 2021
Introduction: The radial artery is an essential artery supplying the structures in the forearm. Variations in the radial artery concerning its origin, course, branching pattern, and mode of termination have been commonly reported. The high origin of the radial artery from either brachial or axillary artery was detected in numerous studies. Clinically-radial artery is used in cardiac catheterization and bypass graft; thus, the knowledge of these variations is of utmost significance to the surgeons. Methods: In the present study, dissection was conducted on 51 upper limb specimens. The explored specimens were obtained from the College of Medicine and Health Sciences (NUST), Oman. Moreover, variations observed in the origin and course of the radial artery were noted and later photographed. Results: Out of the 51 upper limb specimens studied, variation in the origin of the radial artery was observed from the axillary artery in one specimen and the brachial artery in 3 limbs. The course of these varied arteries was superficial in the forearm. Conclusion: The knowledge of the variations in the origin and course of the radial artery will help prevent any untoward side effects that can occur during any procedures involving the radial artery.
High Origin of Radial Artery- A Cadaveric Case Report
Variations in the arterial pattern of the upper limb are very common as observed in many cadaveric and angiographic studies. Knowledge of variations in the origin and course of the radial artery is important because they are used for many diagnostic procedures as well as vascular and reconstructive surgeries like coronary angiography, percutaneous coronary intervention and coronary artery bypass surgery. During routine dissection in our institute, we observed a case of high origin of the radial artery in a 33 year old male cadaver. It was found to be unilateral; on left side, radial artery was taking origin from 3 rd part of the axillary artery at the lower border of pectoralis minor before the origin of subscapular artery and anterior circumflex humeral artery. It had a superficial course in the arm crossing the median nerve from medial to lateral side. The further course of this superficial radial artery in the forearm was normal and it terminated by forming a deep Palmar arch in hand. These variations may be of great clinical implications for vascular and plastic surgeons and radiologists. Superficial course of radial artery makes it vulnerable to accidental injuries and elevates the risk of bleeding.
Anatomical variations of radial artery and its morphology with clinical implications
International Journal of Research in Medical Sciences
Background: The radial artery (RA) is a continuation of the brachial artery and is one of the major blood supplying vessels to the structures of the forearm. It is originated in the cubital fossa at the level of the neck of the radius. It runs on the lateral aspect of the forearm before it reaches the wrist and branches out to supply the hand. The RA is also important clinically due to its location at the wrist, as it can be felt as a pulse and can be used to determine the heart rate. It is the artery of choice for coronary artery angiography, percutaneous coronary artery intervention, cannulation, and others. The main objective of this study is to study the variation in origin and course of the RA in cadavers.Methods: The present study was conducted with 100 upper limbs of 50 cadavers in the department of anatomy, Gouri devi institute medical sciences and hospital, Durgapur, West Bengal over a period of 2 years. By conventional dissection method, the axillary region, arm, forearm, ...
A Study of Variations in the origin and course of Radial Artery
Anatomical variations of Radial artery are of potential clinical implications during vascular and reconstructive surgeries. The cause of abnormal radial artery origin and superficial course may be developmental and genetic. Intended intravenous injections may lead to unintentional intra-arterial injections if superficial radial artery is mistaken for veins. The aim of the present study is to identify the variations of radial artery in its origin in routine cadaveric dissections in the department of Anatomy , Siddhartha Medical College, Vijayawada, NRI Medical College, Chinnakakani and ACSR Govt. Medical College, Nellore. 96 specimens of upper limb were dissected and observed the following variations. From the third part of Axillary artery, Radial artery was found to be originated bilaterally and its course is superficial.. In the middle of the arm radial artery arised from the medial side of the brachial artery bilaterally where it crosses the median nerve and its course is superficial. In the middle of the arm , Radial artery has taken its origin from the lateral side of the brachial artery unilaterally crossing the median nerve near its origin and its course is superficial. Before cardiac procedures, thorough knowledge about the normal anatomy and expected variations of radial artery should be known to cardiac surgeons as the radial artery is the second most commonly used graft in coronary bypass surgeries in place of great saphenous vein and also for trans-catheter coronary interventions.

BACKGROUND: Radial artery is the smaller terminal branch of brachial artery. Abnormal variations in the anatomy of radial artery may produce an iatrogenic injury leading to undesired complications. MATERIALS & METHODS: Study was carried out on 18 formalin fixed cadavers i.e. 36 limbs of adult age in the Department of Anatomy. Arm and forearm of both upper limbs were carefully dissected to note the variation in the origin of Radial artery. RESULT: Unilateral Variations of high origin of Radial artery were observed in two cases (5.55%). In first case, radial artery was originated from right brachial artery 13.5 centimetre above the intercondylar line while in second case it was 19 centimetres above the intercondylar line. CONCLUSION: In recent times, there has been an increase in the use of radial artery for various diagnostic & invasive procedures which requires the qualified apprehension of the variant anatomy to avoid iatrogenic injury and perform safe procedures.

Bilateral superficial radial artery at the wrist associated with a radial origin of a unilateral median artery The radial artery is classically described at the wrist as passing deep to the tendons of the anatomical snuff-box. Variations in the origin and proximal course of this artery are some of the most common anomalies found in the forearm (15%) (McCormack, 1953), but the finding of a radial artery, or one of its branches, passing superficial to the lateral tendons of the anatomical snuff-box is rare. A persistent median artery has an incidence of 8 % (Lippert & Pabst, 1985) but its origin from the radial artery has only rarely been described (Adachi, 1928; Jorge-Barreiro & Valdecasas-Huelin, 1991; Henneberg & George, 1992). The association of a superficial radial artery at the wrist with a median artery arising from it, has not previously been described. Here we present a case of bilateral superficial radial arteries. On the right there was a Manners-Smith type II anomaly and on the left there was a similar situation for the radial artery except that a median artery was also present. Unusually such a median artery arises distally from the radial artery. The superficial radial artery coursed over the lateral tendons in the anatomical snuff-box before terminating in the deep palmar arch. The median artery passed deep to the flexor retinaculum to close the superficial palmar arch. The pattern for the radial artery is similar to that described among primates and some prosimiae. The anomalies reported were found during routine dissection of 40 upper limbs from human cadavers in the Department of Anatomy, Cambridge University, England. The specimens were right and left forearms from an adult male cadaver aged 93 y. In both arms, the brachial artery divided into the radial and ulnar arteries in the cubital fossa. The course and distribution of the ulnar artery was normal in both forearms. The course of the radial artery as far as the lower third of the forearm was normal. At this level it could be subdivided into 2 branches based on their course and situation: 'superficial' and 'deep'. The 'superficial radial artery' passed dorsally around the superficial aspect of the branchioradialis muscle and superficial to the tendons of the anatomical snuff-box to terminate, in the normal way, by passing between the 2 heads of the 1st dorsal interosseous muscle to complete the deep palmar arch (Fig. I A, B). The 'deep radial artery', more slender than the 'superficial' one, descended along the normal course of the 'true radial artery' and passed deep to the tendons of the anatomical snuff-box to terminate as the dorsal carpal branch making up the dorsal carpal arch (Fig. 1A, B).
A study of variable origins of arteries in arm
European Journal of Plastic Surgery, 2007
A series of anomalous arterial supply of the arm and shoulder is presented. In these cases, the deep brachial artery arose from a common trunk with posterior circumflex humeral artery. In one case, the superior ulnar collateral artery and deep brachial artery originated from the posterior circumflex humeral artery. The common trunk or posterior circumflex humeral artery arose from the brachial artery at the level of the lower border of the teres major (at the origin of the brachial artery). A possible ontogenetic explanation is provided for this situation. Awareness of the variations of arteries of the arm or shoulder is important for angiographers and the surgeon who operates in this region.
