Клинические аспекты некоторых вариантов строения поверхностной ладонной дуги человека

Abstract

Abstract Background: Superficial palmar arch plays more important role for hand circulation then the deep one. The classical form of superficial palmar arch is believed to be most common but the presence of variations can reach even 60%. Variations of superficial palmar arch have great clinical importance because sometimes they can change the routine way of surgical procedures or lead to complications. Material and methods: The study included 60 hands of adult human cadavers. All the cadavers were taken from the Normal Anatomy department of Grodno State Medical University and fixed with 10% formalin solution. Topography of superficial palmar arch was studied in all the hands by macro- and micropreparation and variations were noted. Results: Among the observed cadavers 85% hands had the classic anatomy of the superficial palmar arch and the variant patterns were revealed in 15% hands. 12% of cases showed complete variant palmar arch and in 3% of hands it was incomplete. Also we found unusual curves of superficial palmar arch and common digital arteries (coiling) in one right hand. Conclusions: The present study had provided details about some of the rare variants of the superficial palmar arch in humans which will be beneficial for the operating hand surgeons. Current development of microsurgical techniques in reconstructive hand surgery need the understanding of variant arterial arches, the comprehensive knowledge of which is important for the successful operations.
