Abstract
INTRODUCTION: The following study aimed to find the pooled prevalence estimate of anatomical variations in the palmar vasculature, namely the superficial palmar arch (SPA) and the deep palmar arch (DPA). The importance of understanding the vasculature of the hand has become critical with the increasing use of hand microsurgery.
METHODS: Major online medical databases (PubMed, EMBASE, ScienceDirect, and Web of Science) were extensively searched for terms pertaining to the SPA, the DPA, and their anatomy and variations. Articles reporting data on the SPA and/or the DPA were collected and their data extracted. Furthermore, a reference search was performed, allowing to pinpoint any articles that were not previously found. The collected data were analyzed using MetaXL 5.3.
RESULTS: The analysis included 36 studies (n = 4841 palmar arches). The SPA was found to be complete in 81.3% of cases, with the radioulnar anastomosis being the most common variant (72.0%). The incomplete SPA was present in 18.7% of cases, with the ulnar artery supplying the third finger from both radial and ulnar side as the most prevalent in 34.8%. The DPA was found to be complete in 95.2% of cases.
CONCLUSION: In this study, the SPA was predominantly complete, with the anastomosis between the radial and the ulnar artery being most prevalent. Furthermore, the DPA was also complete in the vast majority of cases. The palmar arches and their variations should be kept in mind when considering the use of palmar vasculature for cardiac catheterization and other medical procedures, due to the risk of iatrogenic ischemic hand complications.
