Category: Anatomy


Introduction: Brachial artery is the continuation of the axillary artery at the distal border of teres major. It ends at the level of neck of radius by dividing into radial & ulnar arteries. A detailed description of the vascular pattern of upper limbs especially their variations in their origin & branching pattern is of utmost importance anatomically in general and clinically in particular.

Objective: This study is more informative to know the arterial pattern in this part of Central Gujarat. The primary objective of the study is to establish pattern of human brachial artery &its origin, length, course, branches, and the measurement of the point of origin of branches of the brachial artery. The study also includes the pattern of variations in origin as well as branching

Materials and Method: This is a morphological study in which the study was carried out in 25 cadavers by precisely dissecting brachial artery & its branches. After the dissection each dissected part was cleaned and numbered and the arteries were painted red. The normal and variant arteries were observed and photographs of the variant upper limbs were taken for reference.

Results: In 50 upper extremities, 3 (6%) specimens possessed major arterial variations in the brachial artery and its branches and patterns.

Conclusion: Knowledge of the brachial artery and their variations are of clinical and surgical importance. It is prudent to do pre-operative studies of the brachial and ante brachial arteries and their branching patterns, to prevent possible complications post operatively.

Keywords: Brachial artery, radial artery, ulnar artery, profunda brachii artery.
