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.
Superficial Ulnar Artery: A Cadaveric Study
International Journal of Anatomy and Research
Background: The principal arteries of the upper limb show a wide range of variation that is of considerable interest to orthopaedic surgeons, plastic surgeons, radiologists and anatomists. The main arteries of the forearm are the ulnar and radial arteries, which usually arise opposite the neck of the radius in the inferior part of the cubital fossa as terminal branches of the brachial artery. The superficial ulnar artery is an ulnar artery of high origin that lies superficially in the forearm. Its importance lies on the field of vascular grafting. Knowledge of the course of such superficial artery is also important as it may be accidentally injured during surgery. Many studies have been done previously on regard of this aspect. Materials and Methods: In the present study, 30 upper limbs of 15 cadavers were examined for the presence of superficial ulnar artery during routine dissection for the teaching purpose of undergraduate students for a period of three years in the Department of Anatomy, R G Kar Medical College and Hospital, Kolkata. The course of superficial ulnar artery, if any, was observed along with the course of radial and common interosseous artery of both sides. Observation: In two cadavers, (6.66% of total limbs dissected) the ulnar artery had origin from the brachial artery above the cubital fossa in the arm and proceeded superficially in the forearm but had normal termination in the hand. In one cadaver superficial ulnar artery was originating from the distal third of the brachial artery and on the other cadaver, it was arising from the junction of upper and lower half of the brachial artery. In both the cases, the brachial artery had a usual course in the arm but in the cubital fossa they divided into the radial artery and common interosseous artery and both of them followed the normal course. Conclusion: Knowledge of this variation is important for appropriate planning of operative procedures involving superficial ulnar artery. It is also important as it is highly vulnerable to intra-arterial injection.
Upper limb principal arteries variations: A cadaveric study with terminological implication
Upper limb principal arteries variations: A cadaveric study with terminological implication, 2020
Although the variability of the upper limb arteries is a clinically important problem, the prevalence is varying across the existing studies and classification is rather complicated, not well established and sometimes even unclear for simple and direct understanding and usage. Multiple case reports appearing in the last years apply incorrect, inappropriate, and sometimes misleading terminology. We performed an anatomical cadaveric study of the variability of the arteries of the upper limb, namely, the axilla, arm, and forearm, in 423 upper limbs embalmed with classical formaldehyde method (Central European population). We proposed to apply the Equality system based on the common trunks for denomination of the axillary artery branches principal variations: Truncus subscapulocircumflexus (22.9%), truncus profundocircumflexus (13.75%), and truncus bicircumflexus (13.95%). Further, we proposed the terminology system developed by Rodríguez-Niedenführ et al. for the free upper limb principal arterial trunk variations based on the origin, location (in the arm only, or in the arm and forearm), and course (related to the forearm flexor muscles) of the involved artery: Arteria brachialis superficialis (9.5%), arteria brachioradialis superficialis (6.4%), arteria brachioulnaris superficialis (1.9%), arteria brachiomediana superficialis (0.5%), and arteria comitans nervi mediani manus (3.3%). Extensive development of the catheterization methods via the arteria radialis et ulnaris as well as surgical procedures using flaps based on perforating branches of these arteries (including arteria brachioradialis superficialis et brachioulnaris superficialis) necessitate thorough data on prevalence of the variant vessels for safe performance of these procedures to prevent any unexpected situations or to react adequately in such.
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, ...

Anatomic study of the dorsal arterial system of the hand
2004
Historically, the dorsal arterial system of the hand received less attention than the palmar system. The studies concerning dorsal arterial anatomy present some controversies regarding the origin and presence of the dorsal metacarpal artery branches. Knowledge of the anatomy of dorsal metacarpal arteries is especially applied in the surgical planning for flaps taken from the dorsum of the hand. The purpose of this study is to analyze the arterial anatomy of the dorsum of the hand, compare our observations with those of previous studies from the literature, and therefore to define parameters for surgical planning for flaps supplied by the dorsal metacarpal arteries. METHOD: Twenty-six dissections were performed at the dorsum of the right hand of 26 cadavers by making a distal-based U-shaped incision. After catheterization of the radial artery at the wrist level, a plastic dye solution with low viscosity and quick solidification was injected to allow adequate exposure of even small vessels. The radial artery and its branches, the dorsal arterial arch, the dorsal metacarpal arteries, the distal and proximal communicating branches of the palmar system, and the distal cutaneous branches were carefully dissected and identified. RESULTS: The distal cutaneous branches originating from the dorsal metacarpal arteries were observed in all cases; these were located an average of 1.2 cm proximal from the metacarpophalangeal joint. The first dorsal metacarpal artery presented in 3 different patterns regarding its course: fascial, subfascial, and mixed. The branching pattern of the radial artery at the first intermetacarpal space was its division into 3 branches. We observed the presence of the dorsal arterial arch arising from the radial artery in 100% of the cases. The distance between the dorsal arterial arch and the branching point of the radial artery was an average of 2 cm. The first and second dorsal metacarpal arteries were visualized in all cases. The third and fourth dorsal metacarpal arteries were visualized in 96.2% and 92.3% of cases, respectively. There was proximal and distal communication between the dorsal arterial arch and the palmar system through the communicating branches contributing to the dorsal metacarpal artery formation. CONCLUSION: At the dorsum of the hand there is a rich arterial net that anastomoses with the palmar arterial system. This anatomical characteristic allows the utilization of the dorsal aspect of the hand as potential donor site for cutaneous flaps.
