“…PSAA, often caused by possible fragility of blood vessel walls and repetitive mechanical compression, occurs in 14.3-50.7% of PSA cases. [2][3][4][5][6] Arterial occlusion occurs in 9.0-41.7 % of PSA cases 2,5,12 and frequently coexists with PSAA.…”

“…The literature was searched and revealed no previously reported cases of continuous thrombotic lesions that extended from the IIA orifice to the below-knee arteries. [2][3][4][5][6][7][8][9][10][11][12][13][14] In such cases, the EIA running to the deep femoral artery, could develop as a collateral pathway into the J o u r n a l P r e -p r o o f popliteal artery. However, the EIA in the present case was also thrombosed, and a potential risk of limb loss was high.…”

“…PSA occurs in approximately 0.01-0.06% of the population, and may cause sciatica neuralgia, aneurysmal formation (PSAA), and/or thrombotic occlusion. [1][2][3][4][5][6] Along with surgical bypass and/or resection, endovascular treatment (EVT), including stent-grafting deployment, thrombolysis, and/or embolization, has recently emerged as a key treatment option. 2,[6][7][8][9][10][11][12] This report describes a successful management of a case of a PSAA with thrombotic occlusion extending from the orifice of the IIA and EIA to the below-knee popliteal artery.…”

Persistent sciatic artery (PSA) is an embryologic remnant of the internal iliac artery, and when is present, it undergoes aneurysmal degeneration in up to 60% of the cases. Endovascular repair is an increasingly utilized treatment strategy for PSA aneurysms (PSAAs). The objective was to demonstrate the safety and efficacy of the endovascular repair in patients with PSAA and to identify potential risk factors for loss of patency or limb loss. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and eligible studies were identified through search of the PubMed, Scopus, and Cochrane Central databases. Fifteen case reports, comprising 15 patients overall, were included. The median age of the patients was 68 years old (mean age 66 ± 13.4 years) with half of the reported patients being women. Most patients presented with progressive limb claudication, complaining about an enlarging palpable pulsatile buttock mass. The onset of symptoms was sudden in 78% of the reported cases. Additionally, the distal pulses on PSAA side were diminished or absent in 91% of the patients. Acute limb ischemia was the primary diagnosis in 75% of the cases. All patients underwent endovascular repair of the PSAA with a covered stent. Procedural outcomes were favorable in all patients demonstrating no symptoms recurrence, aneurysmal regression, or total obliteration evaluated by angiographic studies (computed tomography angiography [CTA] and angiogram). Periprocedural imaging evaluation was determined either with CTA or duplex ultrasound (DUS). Periprocedural complications included only 1 endoleak with distal dissection. This endoleak was identified after stent deployment and dissection distal to the aneurysm. Mean follow-up (with CTA and/or DUS) was 22 months, with all patients being asymptomatic with no recurrence of symptom. The endovascular treatment of PSAA with covered stent is safe and effective. Persistent sciatic artery aneurysms is associated with high procedural success, low periprocedural compilations, and favorable mid-term follow-up.

Acute Ischemia of Lower Limbs Caused by Thrombosis of Persistent Sciatic Artery: Case Report

Background: Hypoplasia of the external iliac artery with persistent sciatic artery (PSA) is rare. Patients with this condition seek medical treatment mainly due to the formation of persistent sciatic aneurysm or aneurysm complicated with distal ischemia. Case presentation: In the present study, we report a case of a patient with thrombosis of PSA without aneurysm in the left lower limb that underwent endovascular treatment. Conclusion: Thrombosis of PSA may be associated with sedentary or other unhealthy lifestyles. Endovascular treatment of sciatic arterial diseases could be performed through the brachial artery approach, especially for those with hypoplasia of bilateral iliofemoral arteries.

Treatment Strategy for Persistent Sciatic Artery and Novel Classification Reflecting Anatomic Status

Abstract: occlusive vasculopathies remains unclear. One major problem in trying to formulate meaningful management strategies is a generalised reluctance for HIV patients to return for surveillance.
