The common femoral artery (CFA) divides into the superficial femoral artery (SFA) and deep femoral artery (DFA). The lateral circumflex femoral artery (LCFA) and medial circumflex femoral artery (MCFA) are most often branches of the DFA, although a large number of different variations in their origin has been described. We performed microdissection on both lower limbs of 30 fetuses, gestational age from 7 to 10 lunar months. Our results show that the LCFA and MCFA usually arise from the DFA. In 78.3% of cases, the MCFA originated from the DFA. In 11.7% of cases, the MCFA originated from the CFA, and in 5% of cases from the SFA. One case showed a common trunk with the DFA. Also, the MCFA was missing in one case, and it had a common trunk with the LCFA in one case. In 83.3% of cases, the LCFA arose from the DFA and in 6.7% of cases from the CFA. In one case, it had a common trunk with the DFA, and in one case with the MCFA. In 3.3% of cases, the LCFA was missing. In 66.7% of cases, both arteries originated from the DFA, in 15% of cases one originated from the DFA and the other from the CFA or SFA. Our results are in accordance with some published studies but also differ from the outcomes of other studies. Comprehensive knowledge of different variation types is imperative in order to prevent complications during surgical and orthopedic interventions.

The sural nerve is a sensory nerve, usually formed in the distal part of the leg by the union of the lateral sural cutaneous nerve or the communicating fibular branch with the medial sural cutaneous nerve. The aim of this paper is to present a case of a variant formation of the sural nerve and a review of the literature related to this case. During the dissection of an adult male cadaver, the medial sural cutaneous nerve and communicating fibular branch, after respectively deriving from the tibial and common fibular nerve, were noticed to continue their course without any formation of a unique nerve trunk on the posterior side of both lower limbs. A transverse communicating branch, connecting these two nerves, was present in both legs. As the sural nerve is of significant diagnostic and therapeutic importance, detailed knowledge of the sural nerve's anatomy and its contributing nerves is also of great importance.

The brachial plexus represents a field of many anatomical variations with important clinical implications, especially in the diagnosis and treatment of the thoracic outlet syndrome (TOS). The case described in this paper presented a novel bilateral variation in the relation of the upper trunk of the brachial plexus to the anterior scalene muscle. The ventral rami of the C5 and C6 spinal nerves perforated the anterior scalene muscle simultaneously through a common opening, and joined to form the upper trunk. Previous literature reports described variations of the brachial plexus and the scalene muscles, as well as the embryological basis for their presence. The case reported herein helps to improve the comprehension of the TOS, as well as the diagnostic and therapeutical approach to this syndrome. (Folia Morphol 2019; 78, 1: 195-198)
