Key result
Percutaneous embolization using EVOH as the sole embolic agent achieved complete devascularization in all 7 carotid body paragangliomas, with an average intraoperative blood loss of 55 ml.
Why the study?
Does percutaneous embolization with EVOH achieve devascularization and reduce intraoperative blood loss in patients with carotid body paragangliomas?
Observational (n=7)
Does percutaneous embolization with EVOH achieve devascularization and reduce intraoperative blood loss in patients with carotid body paragangliomas?
Percutaneous embolization with EVOH as the sole agent safely achieves complete devascularization of carotid body paragangliomas, facilitating surgical resection with low blood loss.

May support EVOH embolization for carotid body tumors; leaves open need for prospective validation.
McColl et al. (2010) conducted an observational in Carotid body paragangliomas (n=7). Percutaneous embolization with ethylene vinyl alcohol copolymer (EVOH) was evaluated on Extent of angiographic devascularization and intraoperative blood loss. Percutaneous embolization using EVOH as the sole embolic agent achieved complete devascularization in all 7 carotid body paragangliomas, with an average intraoperative blood loss of 55 ml.
