“…Recently, endovascular techniques such as percutaneous embolization with coils have been tried, providing symptomatic improvement, especially in cases of incomplete PSA where revascularization is usually unnecessary [5,11,17–19]. In cases requiring continuity of the sciatic artery, percutaneous endovascular management of the lesion with stent-graft represents a further treatment option [5,11,17–19].…”

“…In cases requiring continuity of the sciatic artery, percutaneous endovascular management of the lesion with stent-graft represents a further treatment option [5,11,17–19]. However, whether or not endovascular procedures represent a reasonable alternative to classic surgical techniques is yet to be determined, because a stent graft in this location bears the potential risk for graft dislodgment or compression over the hip joint, and its durability remains an open question [11].…”

A case of bilateral persistent sciatic artery with unilateral aneurysm: An 18-year period of graft patency after excision of aneurysm

SummaryBackgroundA persistent sciatic artery (PSA) is a rare vascular anomaly with an estimated incidence of 0.02–0.04% and with a high rate of complications such as aneurysm formation, thromboembolism, and ischemia, that may lead to amputation.Case ReportWe present a case of a female patient with complete symptomatic ambilateral PSA and with unilateral aneurysm. The aneurysm was excised and the PTFE graft was interposed at the aneurismal sac (femoro-popliteal bypass could not be performed because of the high degree hypoplasia of the superficial femoral artery). The graft endured continuous compression and stretching during regular daily life of the patient. At check-up 18 years after the operation, the Doppler ultrasound showed a patent graft and no new aneurismal dilatation of the sciatic artery.ConclusionsTo our knowledge the follow-up of the presented case is the longest reported so far in the literature. The uneventful course of the patient confirms that classical aneurysmectomy still constitutes one of the treatment options of PSA aneurysm.

“…The primitive sciatic artery is given off from the dorsal root of the umbilical artery by as early as 6 mm embryo stage, to serve as the dominant supply for the developing lower limb bud [8–10]. Consequently, it runs dorsally to the growing lower limb all the way to the sole of the foot and forms the adult popliteal and peroneal vessels [4, 8, 9]. The umbilical artery gives off the external iliac artery, proximally to the origin of the sciatic artery [4, 10].…”

“…From the 18 mm embryo stage, the flow from the superficial femoral artery, through the superior communicating ramus, into the popliteal artery, dominates, resulting in the involution and discontinuity of the sciatic artery by the 22 mm embryo stage [10, 11]. The sciatic artery now persists only as the adult inferior gluteal artery [4, 8, 10]. …”

Persistent sciatic artery is a very rare clinical entity. Those of us who have not seen the lesion regard this as a condition which is described in the literature through less than 200 cases. We report, here, a case of a 60-year-old female who presented to the surgical outdoor with complaints of a pulsatile gluteal swelling associated with ischemic changes in the ipsilateral lower limb. On Doppler and CT angiographic analysis, the patient was determined as having persistent sciatic artery aneurysm which was then managed by a combined surgical and endovascular approach. Ours is probably the first such case to be reported from India. The objective of this case report is to highlight the relevant embryology, the pathognomonic presenting features, the diagnostic dilemma, management, and complications associated with a case of persistent sciatic artery (PSA).
