Abstract
BACKGROUND
To review the Shamblin classification of carotid body paragangliomas (CBPs) and the role of intra-arterial stenting in their surgical management.
METHODS
Retrospective case series of 20 patients with 28 CBPs that were surgically resected at our center. Intra-arterial stenting was performed in Shamblin II and II classes.
RESULTS
The mean follow-up was 47.8 months. Five (17.9%) tumors were Shamblin class I, 15 (53.6%) were class II, and 8 (28.6%) were class III. Thirteen (68.4%) CBPs were associated with other paragangliomas. The internal carotid artery (ICA) was stented preoperatively in eight (28.6%) cases and occluded in four (14.3%) cases. The tumor extended to the jugular foramen in six cases (21.4%). Intraoperatively, there was an ICA injury in one case of Shamblin II CBP in the present era.
CONCLUSIONS
The proposed classification enables the clinician to plan the management of the ICA and the right approach. Stenting of the ICA gives a chance for complete tumor removal with arterial preservation.
