Endovascular Treatment for Infectious Sciatic Artery Aneurysm

Abstract

The persistent sciatic artery is a rare congenital disease. Owing to the weak structure of the persistent sciatic artery, it progresses into an aneurysm. The aneurysm causes embolisms or ruptures at times. Thus, timely treatment of the patient with a persistent sciatic artery is important. In this study, we report a case of an 86-year-old woman presented with fever (38°C) and pain in the right buttock. A computed tomography scanning revealed the right persistent sciatic aneurysm and inflammatory changes around the aneurysm. However, the infectious persistent sciatic artery aneurysm of the inflammatory aneurysm could not be diagnosed. Thus, the patient was treated with antibiotics, and improvement of the inflammatory reaction was noted through the results of hematological examinations. The infectious persistent sciatic aneurysm was then clinically diagnosed. Since the patient was too old for the infectious lesions to be excised, the endovascular device VIABAHN 8.0×250 mm was used for treatment. The blood culture test reported negative results and the infection was under control. VIABAHN was placed onto the aneurysm and the operation was performed successfully. The patient was discharged 9 days after the operation. 3 years after the operation, she doesn’t have any signs of infection nor obstruction of the stent. Thus, the infected persistent sciatic artery aneurysm was treated with multidisciplinary treatment. And this case can have the longest patency.
