“…Despite a large number of articles presenting anatomical characteristics of superficial and deep palmar arches, some palmar arteries were only partially described, for example, the thenar arteries coming from the anatomical snuff-box portion of RA. This is obviously true for the SPB of the RA, which was in previous reports only mentioned as a part of SPA [2,5,13,14,23,26].…”

“…Our original contribution to the morphometric and topographic classification of the SPB into two groups was a result of a more detailed analysis of the SPB itself, then in a previous observation of the thenar eminence blood supply [26]. Measuring the calibres and comparing the frequency of well-developed SPBs in our present series of 35 corrosion casts, which was 31.4%, with the earlier incidence of 40% of prominent SPB in 30 human hands, no statistically significant difference was found (χ 2 with Yates correction 0.212, two-tailed p = 0.6453), confirming and supporting our methodological approach.…”

“…Anatomical studies have seldom dealt with the role of SPB in the cutaneous blood supply of the thenar eminence itself [4,17,21,26], or the arterial supply of the thumb [2,15,26], and only rare data is available on the calibre of the SPB [2,5,17]. To our knowledge, there are no articles in the literature describing the branching pattern related to the morphometric features and variations of the SPB.…”

“…Hamahata et al [ 16 ] stated that anastomosis using radial recurrent artery vessels is recommended as a strategy in free radial forearm transplantation for salvage operations. The superficial palmar branch of the radial artery can be also used in plastic and reconstructive surgery as the radial artery superficial palmar branch perforator flap [ 50 – 52 ]. Our present findings indicate that the prominent superficial palmar branch contributed to the formation of superficial palmar arch more often when the brachioradial artery occurred.…”

Background This study thoroughly analyzes the anatomic variations of the brachioradial artery (radial artery of high origin) based on the variability of its origin, the presence and types of anastomosis with the brachial artery in the cubital fossa (“cubital crossover” or “cubital connection”), and the pattern of radial recurrent arteries, as well as the vascular territory within the hand. Material and Methods One hundred and twenty randomly selected, isolated upper limbs fixed in 10% formalin solution were dissected. Results The radial artery was found to have a high origin in 9.2% of total number of the limbs: two cases from the axillary artery; nine cases from the brachial artery. Anastomosis between the brachioradial and “normal” brachial arteries in the cubital fossa was also frequently observed (54.6%). The anastomosis (“cubital crossover”) was dominant in one case, balanced in three cases, minimal in two cases, and absent in five cases. Conclusions The brachioradial artery may originate from the brachial and, less frequently, from the axillary artery. Anastomosis between the brachioradial and “normal” brachial arteries in the cubital fossa may be dominant, balanced, minimal, or absent. A complete radioulnar arch was found more often when the brachioradial artery was present as a variant.

“…Knowledge of the anatomical variations of the arterial supply of the hand, including variability of the superficial palmar arch, is of crucial significance for safe and successful hand surgeries [46–49]. In the study of Rodríguez-Niedenführ et al [12], the PMA supplied the hand by joining the superficial palmar arch (35% of cases with palmar type of the PMA) or by forming some of the common palmar digital arteries (65% of cases presenting palmar type of the PMA).…”

Persistent Median Artery as an Unusual Finding in the Carpal Tunnel: Its Contribution to the Blood Supply of the Hand and Clinical Significance

BackgroundKnowledge of the variable relation of the persistent median artery (PMA) to the median nerve and its contribution to the formation of the superficial palmar arch is of great clinical significance. This study presents a proposal of specific variables which might be introduced to characterize the PMA in the wrist region.Material/MethodsOne hundred and twenty-five randomly selected, isolated upper limbs fixed in 10% formalin solution were subjected to anatomical dissection.ResultsOf the 125 upper limbs, PMA was found in 5 specimens (4% of the total number of limbs). In the carpal tunnel, the artery occupied the anterolateral position (2 cases), the anterior position (2 cases) or the anteromedial position (1 case) in relation to the median nerve. Two types of superficial palmar arches with significant contributions from the PMA were observed in the studied material: complete medio-ulnar arch and an incomplete arch without a connection between the territories of the ulnar and median arteries. The mean ratio of the diameter of the PMA to the diameter of ulnar artery at the level of the wrist was 0.59 (min.=0.38, max=0.83, SD=0.19).ConclusionsOrthopedic and hand surgeons should be aware of the probability of occurrence of the PMA in both planning and conducting surgeries within the wrist region and within the carpal tunnel, as this anomalous vessel might present significant contributions to the arterial blood supply of the hand and might potentially play an important role in the presence of notable clinical symptoms and presentations.
