“…By the 22 mm stage, the SA becomes discontinuous and eventually regresses completely except for segmental remnants. Therefore, it is widely assumed that the persistence of the sciatic portion of the embryonic posterior axial artery and its failure of the anastomosis with the anterior femoral network result in the PSA (Arey, 1965; Donovan & Sharp, 1984; Noblet et al ., 1988; Inoue et al ., 1993). In the present case, the persistence of the sciatic portion of the embryonic posterior axial artery and the dual blood supply by the PSA and the femoral artery were observed 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.

“…The PSA was observed only on the right side, and had an aneurysm (diameter, 24 mm) at its initial segment. The caliber of the PSA was large (13 mm) compared to previous reports (Table 1, Emura et al ., 1991; Inoue et al ., 1993; Tohno et al ., 1993).…”

“…Therefore, detailed information on the running route, caliber, and interrelationship of the PSA with other organs remains to be described. Moreover, only 16 cases were documented in Japanese cadavers (Tohno et al ., 1993; Sekiya et al ., 1997; Yazama et al ., 2002), and those were relatively small caliber PSA with a diameter <5 mm (Emura et al ., 1991; Inoue et al ., 1993; Tohno et al ., 1993). In the present case, we report a very large PSA with a caliber up to 13 mm accompanied with a large aneurysm.…”

Herein is reported a rare case of right persistent sciatic artery (PSA) in the cadaver of a 96-year-old woman who did not have any clinical manifestations related to this anomaly when alive. The anomalous PSA originated from the internal iliac artery, directed toward the infrapiriform foramen, and descended the dorsal side of the thigh. Approximately 20 mm inferior to the infrapiriform foramen, the PSA formed a relatively large aneurysm elongating for approximately 30 mm in length. It then passed under the long head of the femoral biceps muscles, and reached the popliteal fossa, maintaining a constant caliber (approx. 13 mm) as it went down distally. In contrast, the femoral artery was very narrow, and tapered at the level of the knee joint. In addition, the popliteal vein gave rise to two branches, one ran along with the sciatic artery and the other pierced the adductor muscles, and appeared on the ventral side of the thigh. It then drained into the deep femoral vein, which reached the pelvis via the femoral vein. The present case is an interesting example for clinicians who work in pelvic surgery.
