Treatment is faster and outcomes are better at stroke centres dealing with a high volume of patients, finds research published online in the Journal of NeuroInterventional Surgery.
The authors base their findings on 442 patients treated with endovascular therapy—clot busting treatment provided inside the brain via a catheter without the need for surgery—at nine specialist (tertiary) stroke centres between September 2009 and July 2011.
All the patients, whose average age was 66, arrived at the centres within eight hours of the start of their symptoms. They all had a blood clot in a major brain artery, which had cut off blood supply and caused their stroke.
The researchers collected information on age and sex, and risk factors likely to affect the success of treatment, such as high blood pressure, abnormal heart rhythms (atrial fibrillation), diabetes, and high cholesterol.
They also looked at other key factors, including the size and location of the clot, the time taken before treatment was given, and how quickly blood flow was restored (reperfusion).
The data showed that the average time to the start of treatment—insertion of a catheter through the groin—after a CT scan of the brain, and injection of the clot buster drug into the affected artery, to completion of the procedure, was 95 minutes, on average. Read More
