“…Morphological variations of the PA occurred in 28% of cadavers in this study, which was higher than in other studies, in which the prevalence of variations ranged from 4 to 17.6% [1, 3, 5, 7, 11, 12, 14, 16–20, 22, 24, 25, 27, 29, 34, 35, 37]. A few classifications have been proposed for these morphological variants [16, 18].…”

“…The most common morphological variations are associated with high or normal origin, and also concern types [1, 3, 5, 7, 11, 12, 14, 16–20, 22, 24, 25, 27, 29, 34, 35, 37]. High levels of branching of the PA result from variations in the type of regression of the medial division of the sciatic artery [29]. However, when the anterior sciatic artery bundle fails to regress, a common trunk for the ATA and FA is formed, and when the distal portion of the sciatic artery fails to regress, trifurcation occurs [29].…”

IntroductionIdentifying the branching pattern of the popliteal artery (PA) is a vital step in planning radiological and surgical procedures involving the anterior and posterior tibial and fibular arteries. The aim of this study was to characterize the course and morphology of the terminal branches of the PA.Materials and methodsThe anatomical variations in the branching patterns of the anterior and posterior tibial and fibular arteries were examined in 100 lower limbs fixed in a 10% formalin solution. A dissection of the popliteal region of the leg was carried out according to a pre-established protocol, using traditional techniques. Morphometric measurements were then obtained twice by two researchers.ResultsIn most cases (72%) the PA divides to form the anterior tibial artery (ATA) and a common junction for the posterior tibial and fibular arteries (type I), which further splits into the fibular artery and the posterior tibial artery (PTA). This type was subdivided into two subgroups according to whether the ATA (subgroup a) or the common junction of the posterior tibial and fibular arteries (subgroup b) had the larger diameter. Other identified variations included division of the PA into the ATA and PTA—8% (type II), trifurcation—12% (type III), the division of the PTA into the ATA and FA—8% (type IV), and aplasia of the PTA—8% (type IV).ConclusionAlthough the typical PA branching type was observed, it can be classified further into two additional sub-types based on the diameter of the ATA and the common junction of the posterior tibial and fibular arteries.

The study of topographical variations of the branches of the popliteal artery in human fetuses from a macroscopic point of view in modern anatomy is considered relevant and promising. The need to study the anatomy of the terminal branches of the popliteal artery in fetuses of different ages is due to the rapid development of fetal surgery and the improvement in the performance of surgical procedures on the structures of the knee and lower leg areas, since the establishment of the anatomical variability of the vessels of the lower extremities allows choosing the optimal tactics of surgical intervention. In the literature, there are fragmentary data on the fetal topography of the popliteal artery and its branches. The purpose of the study. The study aimed to establish the topographic and anatomical features of the branches of the anterior and posterior tibial arteries in human fetuses of 4-6 months. Material and methods. The study of the fetal anatomy of the popliteal artery was carried out on 34 preparations of human fetuses (81.0-230.0 mm parietococcygeal length) using the methods of anatomical preparation, vascular injection, and morphometry. Results and discussion. In 21 examined fetuses, the classic variant of the branching of the anterior and posterior tibial arteries was observed both on the right and on the left extremity. In other fetuses, atypical variants of the origin and topography of the branches of the popliteal artery were found. The most interesting, from our point of view, was the anatomical variants of the terminal branches of the popliteal artery in fetuses of 160.0, 180.0, and 195.0 mm parietococcygeal length. A high variant of the branch of the peroneal artery from the popliteal artery; a rare variant of doubling the peroneal artery is trifurcation of the popliteal artery into the anterior and posterior tibial and peroneal arteries, doubling of the branches of the tibioperoneal trunk, as well as the formation of anastomoses between them were revealed. Among the most frequent atypical variants of the onset of the peroneal artery in the studied human fetuses was its branch from the tibioperoneal trunk. Conclusion. To obtain a clear idea of the spatial orientation of the peroneal artery in human fetuses, fetal surgeons should distinguish three segments in the peroneal artery trunk: segment I of the peroneal artery (it is proximal part) is the passage of the peroneal artery trunk in the ankle-popliteal canal; segment ІІ (middle part) corresponds to the topography of the peroneal artery in the inferior muscular-peroneal canal; the third segment of the peroneal artery (distal part) is a segment of its trunk from the point of exit from the inferior muscular-peroneal canal to the level of its division into terminal branches

Background The identification of popliteal artery branching variation is of anatomical importance for surgical and endovascular procedures in the posterior region of the knee and below. Purpose To evaluate the variations and associated factors of popliteal artery branching by computed tomography angiography (CTA). Material and Methods CTA of the lower extremities of 1542 lower limbs in 771 patients (513 men and 258 women) were retrospectively reviewed to assess the popliteal artery branching patterns. The patient's sex, side of lower limbs, and population were recorded and evaluated for their association with popliteal artery branching patterns. P < 0.05 was considered to indicate statistical significance. Results Variations in the branching of the popliteal artery were recorded in 9.3% of patients. The three most common variations were found to be hypoplastic-aplastic posterior tibial artery (PT) (3.6%), trifurcation (2.0%), and hypoplastic-aplastic anterior tibial artery (0.8%). A new pattern was detected in 2 (0.1%) cases, which were described as double PTs. Statistically significant differences were noted in the proportion of variation branching between the male and female groups (odds ratio = 1.52; 95% confidence interval = 1.07–2.16; P = 0.02). Conclusion The findings on popliteal variational branching patterns in the present study were in conformance to previous reports. Our study identified a novel variation of popliteal artery branching, which has not been mentioned in the literature so far. Sex was found to be an associated factor of branching variation.
