Surgical Management Strategies for Carotid Artery Invasion by Head and Neck Cancer: Ligation Versus Reconstruction.

Objective: Whether ligation or reconstruction should be performed after radical resection of the tumor and carotid artery in patients with head and neck cancers invading the carotid artery (HNC‐CA) has been controversial. This paper provides a review and meta‐analysis of the efficacy of these 2 modalities. Data Sources: PubMed, Cochrane, Web of Science, Scopus, and Ovid databases were searched through August 2023. Review Methods: Descriptive, graphical, tabular, and quantitative data were extracted. The statistical outcomes (risk difference, RD) were synthesized under a random‐effects model. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta‐analyses reporting guidelines. Results: A total of 22 papers and 337 patients met the inclusion criteria for the literature review. Statistical analysis showed that the RD of overall survival (OS) rate at 1‐year was 32% (95% confidence interval [CI]: 21%‐42%) for ligation and 70% (95% CI: 65%‐76%) for reconstruction (P <.05). The RD for OS rate at 2‐year was 16% (95% CI: 7%‐26%) for ligation and 39% (95% CI: 30%‐47%) for reconstruction (P <.05). The RD for disease‐free survival rate at 1‐year was 27% (95% CI: 17%‐38%) for ligation and 60% (95% CI: 51%‐70%) for reconstruction (P <.05). There were no statistically significant differences (P >.05) between the 2 surgical modalities in terms of locoregional recurrence rate, carotid blowout rate, surgery‐related complications rate, neurological complications rate, and perioperative mortality rate. Conclusion: This review demonstrates the significant advantage of carotid artery reconstruction surgery in short‐term patient survival, thus making it a recommended option for HNC‐CA patients undergoing radical surgery.
