Knowledge of the variations in the arterial supply of hand has reached a point of practical importance with the advent of microvascular surgery for revascularization, replantation and composite tissue transfers. Arterial supply of hand is derived from two anastomotic arches, formed between two main arteries of forearm i.e. radial, ulnar and their branches, in the palm.
The superficial palmar arch shows variation in formation at the radial side. In the present study we have recorded its data which would help in its clinical and surgical implications.
In the present study we have studied the formation of superficial palmar arches and their variations in 100 cadaveric hands at Dr. D . Y. Patil Medical College, Pune and B.J. Government Medical College, Pune, India.
According to Adachi's classification the most predominant pattern obseved was of Ulnar type arch (66%). According to Coleman and Anson classification 82% showed complete (Group I) superficial palmar arches and a very low incidence (18%) of incomplete arches (Group II). This suggests that collateral circulation is present in majority of cases. This would result in least number of complications considering radial artery harvesting for coronary bypass. Sub-classification of arches according to Coleman and Anson 1961 indicates that the predominant type in the present study was of Group I (Type B) which is formed entirely by Ulnar Artery (56%). Median artery and ulnar artery forming an incomplete superficial arch under Group II (Type C) having an incidence of 4% was recorded. Thus in such cases radial artery harvesting for coronary artery bypass may prove to be less fatal. This study is an effort to provide data about the formation of superficial palmar arches which has been a centre of attraction for most of the surgical procedures and injuries of the hand.
随着用于血管重建、再植和复合组织移植的微血管手术的出现，手部动脉供应变异的知识已达到具有实际重要性的程度。手部的动脉供应源自两个吻合弓，它们在前臂的两条主要动脉即桡动脉、尺动脉及其分支之间在手掌中形成。
掌浅弓在桡侧的形成存在变异。在本研究中，我们记录了其数据，这将有助于其临床和手术应用。
在本研究中，我们在印度浦那的迪帕克·帕蒂尔医学院和浦那的BJ政府医学院对100具尸体手的掌浅弓形成及其变异进行了研究。
根据足立分类法，观察到最主要的类型是尺型弓（66%）。根据科尔曼和安森分类法，82%显示为完整的（I组）掌浅弓，不完整弓（II组）的发生率非常低（18%）。这表明在大多数情况下存在侧支循环。考虑到为冠状动脉搭桥采集桡动脉，这将导致最少的并发症。根据科尔曼和安森1961年的分类法对弓进行的亚分类表明，本研究中主要类型是I组（B型），它完全由尺动脉形成（56%）。记录到正中动脉和尺动脉在II组（C型）下形成一个不完整的浅弓，发生率为4%。因此，在这种情况下，为冠状动脉搭桥采集桡动脉可能证明致命性较小。本研究旨在提供有关掌浅弓形成的数据，掌浅弓一直是大多数手部手术和损伤的关注焦点。
