Abstract

Objective: Persistent sciatic artery (PSA) is a rare abnormal vascular condition, accounting for only 0.025% - 0.05%. Patients are often hospitalized because of complications such as embolism, chronic anemia or aneurysms sciatic artery. Method: We present a case of 70-year-old female patient admitted to the hospital after 3 days of acute obstruction due to a thrombus from the left common iliac artery. Computed tomography artery (CTA) and postoperative ultrasound detected the presence of sciatic artery on both sides and thrombosis causing obstruction of left sciatic artery. Thrombectomy of the left iliac artery was performed. Result: Three months follow up with clinical examination and ultrasound shows a good result. The patient had no intermittent claudication and could walk normally. Ultrasound presented a good circulation of the anterior and posterior tibial arteries. Conclusion: PSA is a very rare condition. Diagnosis is based on CTA and ultrasound, but difficult in less experience with this disease. Treatment choice depends on the features of anatomical abnormalities.
