BACKGROUND: Severe @entity2998 stenosis accounts for 5-10   % of all @entity385 . Currently, therapeutic recommendations are undergoing changes, particularly regarding the treatment of asymptomatic @entity850 . Consolidated knowledge on the indications, nationwide distribution and numbers of cases are not available. Moreover, the impact and grade of implementation of the recently published national S3 guidelines on the reality of medical treatment remain unclear. METHODS: Analysis of administrative hospital data involving the diagnosis-related groups (DRG) statistics and structured quality reports for 2010 and 2013 to evaluate the procedural therapy trends concerning operative and interventional approaches for symptomatic and asymptomatic @entity2998 stenoses. RESULTS: In Germany approximately 37,000 carotid endarterectomies (CEA) and approximately 5,000 @entity3538 ( @entity3538 ) are carried out per year. Approximately 94   % of CEA and 62   % of @entity3538 are performed in centers with more than 25 procedures per year. Only 33   % of CEA and 39   % of @entity3538 are related to symptomatic @entity850 . CONCLUSION: Mathematically, an undertreatment of symptomatic and an overtreatment of asymptomatic @entity2998 stenoses become apparent. Efforts should be made to achieve inpatient medical treatment conforming to the national S3 guidelines, in particular to adequately reduce the risk of @entity64 recurrence in @entity1 with @entity731 symptomatic carotid @entity2791 .
