“…Further studies are needed to clarify the relation of the PSA to the inferior gluteal artery. The PSA usually receives 3–4 perforating arteries from the profunda femoris (Job, 1934; Arey, 1965; Blair & Nandy, 1965), and supplies the fine muscle branches to the hamstring and adductor magnus muscles (Blair & Nandy, 1965). In this case, the course of the PSA seems almost typical, supplying the long head of the biceps femoris, the semitendinosus and the semimembranosus muscles on both sides.…”

During student dissecting practice, a rare developmental anomaly showing persistent sciatic artery (PSA) was found in the bilateral lower limbs of a 74-year-old Japanese male cadaver. The PSA was a continuation of the internal iliac artery on both sides, did not anastomose with the perforating arteries and ended by anastomosing with the popliteal artery on both sides. The course and distribution of the PSA were relatively consistent with previous reports. In the present case, however, the PSA and inferior gluteal arteries existed simultaneously on both sides, despite the general assumption that the inferior gluteal artery is a remnant of sciatic artery regression.

“…On the other hand, the sciatic artery is interrupted shortly and distributes mainly to the gluteal muscles as the inferior gluteal artery. Accordingly, an anomalous long artery that branches from the inferior gluteal artery has been customarily considered to be the human persistent sciatic artery among anatomists if this anomalous artery accompanies the sciatic nerve, distributes to the lower part of some femoral flexor muscles or anastomoses to the popliteal artery (Adachi, 1928;Yokoo, 1932;Job, 1933;Finerty, 1947;Mada, 1955;Nakamura and Kasai, 1956;Kubota et al, 1958;Blair and Nandy, 1965;Yoshimura et al, 1988;Ukeshima et al, 1990;Emura et al, 1991;Inoue et al, 1993;Tohno et al, 1993;Sekiya et al, 1997;Kodama, 2000) (Fig. 1).…”

Summary:The main aim of this review is (1) to introduce the two previous studies we published human lower limb anatomy based on the conventional macroscopic anatomical criteria with hazardous recognition of this description, (2) to activate the discussion whether the limb homology exists, and (3) to contribute to future study filling the gap between the gross anatomy and embryology.One of the topics we discussed was the human persistent sciatic artery. To date, numerous human cases of persistent sciatic artery have been reported in which the anomalous artery was present in the posterior compartment of the thigh alongside the sciatic nerve. As one of the important criteria for assessing the human primitive sciatic artery, its ventral arterial position with respect to the sciatic nerve is reasonable based on the initial positional relationship between ventral arterial and dorsal nervous systems and comparative anatomical findings. We also discuss ways of considering the topography of muscles of the lower limb and their innervations compared to those of the upper limb. We propose a schema of the complex anatomical characteristics of the lower limb based on the vertebrate body plan. According to this reasonable schema, the twisted anatomy of the lower limb can be understood more easily.These two main ideas discussed in this paper will be useful for further understanding of the anatomy of the lower limb and as a first step for future. We hope that the future study in lower limb will be further developed by both viewpoints of the classical gross anatomy and recent embryology.

“…posterior or inferior) side of the hip. Despite this suggested lengthening of the nerve course in foetuses, many dissection studies have indicated the presence of an artery accompanying the adult sciatic nerve (arteria comitans nervi ischiadici) [1,5,7,8,14,15,21,33,36,37,40]. Moreover, vascular surgeons have recently drawn attention to aneurysms of this accompanying artery as a cause of leg pain or paralysis, such reports [6,18,22,25,34] having increased significantly in number since the year 2000.…”
