UF Health Stroke Outcomes

Aneurysm Procedures  UF Health 2015 Mortality Rate  National Benchmark
Unruptured Clipping 0% <2.7%
Unruptured Coiling 0% <3.4%
Ruptured Clipping 17% <9.9%
Ruptured Coiling 7% <8%

Our national benchmarks for the aneurysm procedures were based on mortality data from the International Subarachnoid Aneurysm trial (ISAT)(1-2) for ruptured aneurysms and the International Study of Unruptured Intracranial Aneurysms (ISUIA)(3) for unruptured aneurysms. *1, 2, 3

Carotid Procedures UF Health 2015 Complication Rate National Benchmark
Asymptomatic CEA 0% <3%
Asymptomatic CAS 0% <3%
Symptomatic CEA 6% <6%
Symptomatic CAS 6% <6%

The carotid procedures benchmarks are provided by The Joint Commission.
