Neurovascular outcomes and predictive factors following carotid body tumor surgical resection

Abstract : Objectives: Our retrospective study aims to report our experience in the management of carotid body tumors and to evaluate the early and late postoperative neurovascular complications according to the Shamblin classification and tumor size. Study Design: We performed a retrospective study on 54 carotid body tumor resections in 49 patients, between 1980 and 2011. The data was analyzed including early and late postoperative complications and sequelae at 18 months. Results: The median follow-up was 17 months (IQR, 10-67 months). Carotid body tumors were classified according to Shamblin classification: group I (n=17), group II (n=25), and group III (n=12). Early postoperative complications occurred in 31 cases, including 30 cases of cranial nerve deficit. Cranial nerve deficit occurred in 83% of Shamblin III tumors and the mean tumor size was significantly larger in patients with deficit (4cm ±1.4 versus 2.9 ±1.3; p<0.01). Shamblin III tumors and tumor >3.2 cm were considered as predictive factors for early postoperative peripheral neurological complications. There was no cranial nerve deficit recovery in 8 patients, even after 18 months of follow-up; no predictive factor was identified. Conclusion: Surgical resection remains the only curative treatment with low vascular morbidity. However early postoperative nerve deficits are still frequent, most of them are temporary and they show recovery within 18 months. Tumor size and Shamblin classification correlate with neurovascular complications.
