Different Manifestations of Persistent Sciatic Artery and Possible Treatment Options: A Series of Four Cases

Persistent sciatic artery (PSA) is a rare vascular anomaly classified into five types according to the Pillet and Gauffre classification system. Although PSA may be detected as an incidental finding, symptomatic cases account for approximately 80% of all cases and have variable clinical presentations. Due to the frequent ischemic and aneurysmal complications, PSAs can lead to limb-threatening conditions requiring prompt identification and adequate treatment management. In this paper, we present a series of four cases of PSA with extremely different anatomical characteristics, patients’ ages, medical histories and clinical presentations. All cases were diagnosed in our institution and managed after multidisciplinary discussions involving vascular surgeons and interventional radiologists. The series included three women and one man. In two cases, one of which included gluteal and back pain, pulsatile masses were found. Two patients had lower-limb chronic ischemia, one with rest pain and one with IIb claudication. Whereas selective angiography was performed only in endovascular approaches, computed tomography angiography (CTA) was performed on all patients as the decisive diagnostic modality. In our series, treatment strategies were selected on the basis of clinical and anatomical factors, and after the evaluation of the potential risks and benefits of each technique. Treatment was medical in two cases, endovascular in one case and hybrid in one case.

Persistent Sciatic Artery Aneurysm With Distal Embolization Treated Endovascular - A Case Report.

Persistent sciatic artery (PSA) is a rare embryologic remnant of the internal iliac artery variant with an estimated incidence of 0.03-0.06 %. Aneurysmatic formation can give rise to neurological sciatic nerve compression symptoms or thromboembolic and ischemic symptoms. The present is a case with recurrent thromboembolic symptoms and PSA aneurysm, successfully treated endovascularly.

Acute Limb Ischemia Secondary to Thrombosis in Persistent Sciatic Artery: A Case Report and Review of Management Strategies

Persistent sciatic artery (PSA) is a rare vascular anomaly with potential for significant vascular complications. We present a case of a 39-year-old male with acute limb ischemia secondary to thrombosis in a PSA, highlighting the challenges in diagnosis and management. Despite the absence of aneurysmal formation, the patient presented with severe pain and absent distal pulses, prompting urgent intervention. Computed tomography angiography revealed thrombosis extending into the left common iliac artery. Catheter-directed thrombolysis (CDT) was successfully performed, resulting in complete resolution of the thrombus and restoration of limb perfusion. The patient experienced symptomatic relief postoperatively and regained ambulatory function. This case underscores the importance of considering PSA in the differential diagnosis of acute limb ischemia and highlights CDT as an effective treatment modality. Further research is needed to optimize the management of acute limb ischemia associated with PSA and to evaluate long-term outcomes.

Persistent Sciatic Artery in Right Lower Extremity Complicated by Thrombosis: A Case Report.

Persistent sciatic artery (PSA) is a rare congenital vascular malformation with an incidence of approximately 0.025% to 0.04%. Persistent sciatic artery has major complications, such as aneurysms, thrombosis, and occlusion. Complications may lead to a range of serious clinical problems, and a timely diagnosis of this vascular variant is crucial to avoid life-threatening complications. A 65-year-old man was admitted to the hospital with pain and chills in the right lower extremity for 2 months, which gradually worsened. This was accompanied by numbness in the right foot for the last 10 days. Computed tomography angiography showed that the right inferior gluteal artery and right popliteal artery of the right internal iliac artery were connected, which is considered a congenital developmental variant. This was complicated by multiple thromboses of the right internal and external iliac arteries, and the right femoral artery. After admission to the hospital, the patient underwent endovascular staging surgery to relieve numbness and pain in the lower extremities. Treatment strategies can be selected based on the anatomical characteristics of PSA and superficial femoral artery. Asymptomatic patients with PSA can be closely monitored. Surgery or individualized endovascular treatment plans should be considered for patients with aneurysm formation or vascular occlusion. For the rare vascular variation of the PSA, clinicians must make a timely and accurate diagnosis. Ultrasound screening is essential, which requires experienced ultrasound doctors to be aware of vascular interpretation and develop personalized treatment plans for each patient. In this case, we adopt staged a minimally invasive intervention to solve the problem of lower limb ischemic pain for patients. This operation has the advantages of rapid recovery and less trauma, which has important reference significance for other clinicians.

Catheter-Directed Thrombolysis for Persistent Sciatic Artery Presenting with Acute Limb Ischemia

Persistent sciatic artery (PSA) is a rare congenital peripheral artery disorder that is usually detected incidentally on computed tomographic examination. PSA can also cause iliac aneurysm and acute thromboembolism, which are potentially associated with rest pain, claudication, and limb-threatening ischemia. Patients with PSA and leg ischemia should be treated with revascularization and appropriate management of PSA aneurysm. The authors often choose emergent bypass surgery or endovascular intervention for aneurysmal rupture and acute lower-extremity arterial occlusion. This report describes an emergency procedure using catheter-based thrombolysis for acute limb ischemia in a patient with PSA.

Persistent Sciatic Artery: A Cadaveric Case Study

Objective The persistent sciatic artery associated with birth is a rare anomaly with a high rate of abnormal dilatation, blockage and stenosis prompting in extreme thrombosis, caudal embolisation, or aneurysm rupture. This is a case report on cadaveric specimen (50-year-old) African female cadaver in the Human Anatomy Laboratory, Department of Human Anatomy, Uzima University. Methods: During routine cadaveric dissections by first year medical students a peculiar structure was noted behind the right thigh after exposure of gluteal muscles. Results: The structure, identified as persistent sciatic artery, entered the gluteal region through the greater sciatic foramen and lied superficial to the sciatic nerve. The vessel was large and it passed out of the pelvis through the greater sciatic foramen below the pirifomis and descended posterior to the sciatic nerve. Muscular and articular branches branched off from artery through its course. The artery descended behind the thigh and was traversed obliquely by the long head of the biceps femoris muscle posteriorly. The sciatic artery continued as the popliteal artery that lied alongside popliteal vein, which was retraced back from the infrapiriform fossa. The femoral arteries were hypoplastic and had no obvious connections with the sciatic artery. Conclusion: It is a vital practice to recognize the position and tendency of sciatic artery to develop aneurysms and subsequent deep vein thrombosis that may be life threatening. Furthermore, understanding of this principle changes the approach to surgical interventions that are required during the process of bypass grafting.

Persistent Sciatic Artery: A Case Report

Persistent sciatic artery (PSA) is a very rare congenital vascular anomaly, occurs in 0.025% to 0.04% of the population, and occasionally associated with thromboembolic events or aneurismal diseases. We herein share experience of diagnosis and successful treatment of a Vietnamese patient with PSA complicated with distal thromboembolism. A 70-year-old woman was admitted to the hospital for acute lower limb ischemia. A computed tomography angiography (CTA) revealed complete occlusion of the left common iliac artery. Surgical embolectomy was carried out and abnormal distal left femoral artery was noted intraoperatively. Postoperative CTA showed a persistent sciatic artery (PSA) on the left and adequate perfusion of the left lower limb. During 2 years follow-up, the patient remained symptom-free with good perfusion to the distal left popliteal artery, anterior and posterior tibial arteries.

An Infected Massive Persistent Sciatic Artery Aneurysm Treated by an Aneurysmal Incision and Drainage after Angiographic Embolization.

A man in his 80s undergoing chronic hemodialysis presented with a high fever. A 10-cm soft mass was palpable in his right buttock. Abdominal computed tomography and angiography showed an incomplete-type unilateral persistent sciatic artery aneurysm (PSAA) with gas patterns and a blood flow through the aneurysm. Incision drainage was performed after arterial embolization. Gram staining of the hematoma showed gram-positive cocci that had formed chains, thus leading to a diagnosis of an infected PSAA. Drainage by incision after arterial embolization was used as the therapeutic method of choice for a massive infected PSAA with a sustained blood flow in order to prevent sciatic nerve injury and bleeding associated with PSAA resection.

1529 Management of A Rare Case of Bilateral Persistent Sciatic Artery Aneurysms Causing Critical Limb Ischaemia With Staged Embolisation And Femoropopliteal Bypass: A Case Report

Abstract Introduction Bilateral persistent sciatic arteries (PSA) are rare with an incidence of 0.001%. They represent a persistence of the embryonic axial limb circulation via the internal iliac artery. Normally the PSA involutes and is replaced by the superficial femoral artery (SFA). Failure of regression leads to a PSA with varying configurations. Up to 50% of PSAs are aneurysmal and may present with rupture or acute/chronic ischaemia, typically at 40-50 years old. Case Report A 74-year-old female presented with limb threatening ischaemia manifesting with rest pain, sensory deficit and early tissue loss (Rutherford IIb). She had a left femoral pulse but absent pulses distally. Pedal pulses were noted on the contralateral limb. CT angiogram revealed bilateral complete PSAs with incomplete hypoplastic SFAs (Pillet-Gauffre 2a). Both PSAs were aneurysmal; the left PSA was acutely occluded distal to the aneurysm. She underwent staged intervention with percutaneous embolisation of the left PSA, followed by femoropopliteal bypass. She was discharged six days later with good symptomatic relief at one month follow up. We are planning to treat the contralateral limb in a similar manner electively in case complications occur. Conclusions PSAs are commonly associated with limb threatening complications but due to their rarity there are limited reports on the management of this condition. Here we can report a good outcome in a late presentation using staged embolisation with open reconstruction.

The Persistent Sciatic Artery Aneurysm a Cause of Recurrent Limb Ischemia – A Rare Case Report

A persistent sciatic artery (PSA) is a rare vascular anomaly. It can cause complications, including acute and chronic limb ischemia, aneurysm formation, and compression of adjacent tissues during early embryonic development, the sciatic artery usually disappears when the superficial femoral artery has developed properly. PSA is usually an incidental finding and is exceedingly rare to find bilaterally. We are presenting a rare case of unilateral PSA aneurysm presented as an episode of recurrent acutely ischemic limb.
