Surgical outcome of Carotid body tumor resection after percutaneous embolisation with ethylene-vinyl alcohol copolymer (Onyx®).

Conclusion:    Preoperative embolization reduces intraoperative blood loss, improves operative field visualisation and consecutively diminishes damage to nerval and vascular structures. Percutaneous embolization via direct intratumoral puncture appears to achieve a higher degree of devascularization by affecting arterial vessels, capillary bed and venous drainage. Existing data suggest a decrease in intraoperative blood loss and fluoroscopy times over transarterial embolization.
