A Case of Common Peroneal Nerve Palsy Associated with Internal Iliac Artery Embolization by Using N-butyl-2-cyanoacrylate (NBCA).

A 64-year-old man was scheduled to undergo endovascular aneurysm repair for an abdominal aortic aneurysm (AAA). Since preoperative computed tomography showed an AAA with common iliac artery and internal iliac artery (IIA) aneurysms, IIA embolization was scheduled. Embolization using a coil was supposed to be performed; however, the lateral sacral artery could not be selected. For this reason, IIA embolization using N-butyl-2-cyanoacrylate (NBCA) was undertaken. During embolization, the median sacral artery was unexpectedly embolized through the lateral sacral artery. The patient complained of drop foot just after embolization; he was diagnosed with iatrogenic common peroneal nerve palsy. We have learned that sciatic nerve palsy can occur in cases of embolization with a liquid NBCA-Lipiodol mixture to the lateral or sacral median artery.
