Key result
Preoperative embolization before carotid body tumor resection did not significantly reduce intraoperative estimated blood loss compared to surgery without embolization (305 mL vs 265.6 mL).

Absolute Event Rate: 305% vs 265.6%
Preoperative embolization before carotid body tumor resection does not significantly reduce intraoperative blood loss compared to surgery without embolization.
Zeitler et al. (2010) conducted an observational in Carotid body tumors (n=25). Preoperative superselective angiography with embolization (PSE) vs. Excision without PSE was evaluated on Estimated blood loss (EBL). Preoperative embolization before carotid body tumor resection did not significantly reduce intraoperative estimated blood loss compared to surgery without embolization (305 mL vs 265.6 mL).
