Abstract
Objective: The authors report a case of migration of glue (NBCA : nbutyl2cyanoacrylate) during presurgical direct puncture embolization of carotid body tumor.
Case presentation: A 42yearold woman had a gradually enlarging mass at the left neck. She underwent presurgical embolization of the tumor under the diagnosis of carotid body tumor. After failed transarterial embolization due to numerous but tiny feeding arteries, direct percutaneous embolization of the tumor using 20% NBCA was performed under fluoroscopic loadmap guidance. No neurological complications were caused by the procedures, though retrograde migration of NBCA into the occipital artery and facial artery occurred during the procedure. Postembolization angiography showed complete devascularization of the tumor. The tumor was completely removed without massive bleeding during surgery the day after the embolization. Histological examination revealed the diagnosis of paraganglioma. Her postoperative course was uneventful.
Conclusion: Presurgical direct percutaneous embolization with NBCA would be an effective procedure to control bleeding during removal surgery for a carotid body tumor. However, a careful attention should be paid for migration of NBCA into surrounding normal arteries to avoid neurological complications.
