| Popis: | WHAT THIS PAPER ADDS The literature on the safety of carotid endarterectomy (CEA) after intravenous thrombolysis (IVT) consists of relatively small series. This study presents the first very large registry based case controlled study on a consecutive series of patients having CEA with or without previous IVT for acute stroke. Equally low procedure related stroke and death rates were found in the two groups. Despite weaknesses in this study, including lack of data on the interval from symptoms to CEA in the control group, the results support the indication that CEA can also be performed within the recommended 2 weeks in patients having had IVT. Objective: Few studies have been published on the safety of carotid endarterectomy (CEA) after intravenous thrombolysis (IVT). Registry reports have been recommended in order to gather large study groups. Design: A retrospective, registry based, case controlled study on prospectively gathered data from Sweden, the capital region of Finland, and from Denmark, including 30 days of follow up. Methods: The study group was a consecutive series of 5526 patients who had CEA for symptomatic carotid artery stenosis during a 4.5 year period. Among these, 202 (4%) had IVT prior to surgery, including 117 having CEA within 14 days, and 59 within 7 days of thrombolysis. IVT as well as CEA were performed following established guidelines. The median time from index symptom to CEA was 12 days (range 0e130, IQR 7e21). Results: The 30 day combined stroke and death rate was 3.5% (95% CI 1.69e6.99) for those having IVT þ CEA, 4.1% (95% CI 3.46e4.39) for those having CEA without previous IVT (odds ratio 0.84 [95% CI 0.39e1.81]), 3.4% (95% CI 1.33e8.39) for those having IVT þ CEA within 14 days, and 5.1% (95% CI 1.74e13.91) for those having IVT þ CEA within 7 days. Conclusion: Data on the time from symptoms to CEA in patients not having IVT, Rankin score, degree of stenosis, and cerebral imaging were not available. Despite its weaknesses, this study reasserts that CEA can be performed within the recommended 2 weeks of the onset of symptoms and IVT without increasing the risk of peri-operative stroke or death. Centres and vascular registries are recommended to continue monitoring changes in patient characteristics, lead times, and major complications after CEA in general, with a special focus on those who have undergone a prior thrombolysis. |
