Name of journal: CureusAbstract: Preoperative embolization via transarterial route is an acceptable adjunct to the treatment of carotid body tumors (CBT). Direct tumor puncture for embolization has been previously described as a safe and feasible option. We revisit this technique and present our initial experience treating CBT via direct puncture. We identified six patients that underwent preoperative embolization of CBT using a direct puncture technique embolized with Onyx (EV3 Micro Therapeutics Inc., Irvine, CA, USA). After defining the angioarchitecture via digital subtraction angiography, the tumor was targeted with Onyx. Using a 21-gauge needle, the tumor was punctured using a fluoroscopic road mask. There were no immediate post-procedural complications following embolization. All patients underwent definitive resection within 24 hours. During surgery, the embolization material did not affect surgical maneuvers. In addition, the estimated blood loss was noted to average 50 ml. Although early in our experience, direct percutaneous embolization of CBT appears to be a reproducible and well-tolerated endovascular treatment option. Overall, the reported body of evidence available confirms the safety and efficacy of direct intralesional embolization with Onyx.
