Early Volumetric and Biochemical Effects of Embolization in Head and Neck Paragangliomas.

Preoperative embolization is commonly performed for head and neck paragangliomas to reduce intraoperative bleeding; however, its early effects on tumor volume and catecholamine secretion remain unclear. We retrospectively reviewed 14 consecutive patients with head and neck paragangliomas who underwent embolization foll...

Prompt volumetric responses following preoperative embolization of skull base meningiomas: association with intratumoral contrast enhancement loss.

OBJECTIVE The role of preoperative embolization for skull base meningiomas remains controversial because potential surgical benefits must be balanced against endovascular procedural risks. Although embolization may induce early tumor volume reduction, evidence in skull base meningiomas remains limited. This study evalu...
