ABSTRACT
Background: The complex and variable pattern of the arterial arcades of the palm form an interesting area of study anatomically and surgically. In the present study arches were classified into complete and incomplete types, the complete type being the most prominent in 88.6% of the palms. Among the complete type, arch formed by ulnar artery alone supplying the thumb and index finger was found in majority of the specimens (50%). The classical or standard superficial palmar arch formed by the superficial palmar branch of radial and ulnar arteries was found in only 28.5%. Different patterns of the arterial arcades of the superficial palmar arch are normally encountered during routine anatomical dissections of the palm which needs to be emphasized and highlighted for a desired surgical out come during microvascular reconstructive surgeries of the palm and during radial artery cannulation.
Context: With technological advancements in microsurgical procedures of the hand, fields of anatomical interest like the classification of arterial arcades of the palm, now becomes essential for operating vascular surgeons for a desired surgical outcome
Purpose of the study: The present study was taken up to analyze and document varying patterns of the arterial arcades of the superficial palmar arch.
Methods and Material: the study was conducted by dissecting 70 randomly obtained formalin fixed cadaver palms.
Results: In the present study arches were classified into complete and incomplete types, the complete type being the most prominent in 88.6% of the palms. Among the complete type, arch formed by ulnar artery alone supplying the thumb and index finger was found in majority of the specimens (50%). The classical or standard superficial palmar arch formed by the superficial palmar branch of radial and ulnar arteries was found in only 28.5%. Out of the 70 hands, incomplete arches were found only in 8 hands with an incidence of 11.4%.
Conclusion: Knowledge of arterial pattern of the hand is very important to vascular and reconstructive surgeons for effective treatment of injuries of the hand. Such a knowledge of the disposition of the arterial arcades of the palm also enables cardio-vascular surgeons to plan and modify surgical procedures such as radial artery harvesting, cannulation and in preventing the ischemia of hands in such procedures.
Key words: Superficial palmar arch, Arterial arcades, Complete arch, Incomplete arch.
