Chemodectomas are rare neuroendocrine tumors that typically arise at the carotid bifurcation and progressively englobe the internal and external carotid artery. Surgical asportation of the capsulated mass is the elective treatment. Pre-procedural embolization of this high vascular tumors is highly recommended because it has shown to improve surgical outcome by reducing both, mean blood loss and total operation time. Many different embolization techniques have been described in literature. In the here presented case we opted for an endovascular approach using resorbable purified porcine skin gelatin cross-linked with glutaraldehyde microspheres (Optisphere - MEDTRONIC) as an embolic agent. These turned out to be very safe and effective in improving surgical outcome by reducing operative blood loss and thus reducing treatment-related morbidity.
化学感受器瘤是一种罕见的神经内分泌肿瘤，通常发生在颈动脉分叉处，并逐渐包围颈内动脉和颈外动脉。手术切除囊状肿块是首选的治疗方法。由于术前栓塞这种高血管肿瘤可以减少术中平均失血量和总手术时间，因此强烈推荐这种治疗方法。文献中已经描述了许多不同的栓塞技术。在本病例中，我们选择了一种使用可吸收的纯化猪皮明胶交联戊二醛微球（Optisphere - MEDTRONIC）作为栓塞剂的血管内方法。这些方法在减少手术相关发病率方面通过减少手术失血量来改善手术结果，非常安全有效。
