Thrombolysis enters the race: a new era for acute ischaemic stroke?
Thrombolysis has been shown to be an effective treatment for ischaemic stroke. The major obstacles to more widespread use of this therapy are lack of awareness that treatment is possible and the short, less than 3 hours, therapeutic window. Even though the use of this therapy can be burdened by the occurrence of intracerebral haemorrhages, there is tantalizing evidence that thrombolysis is the only approach that has been so far demonstrated to improve the outcome of these patients. Early recognition of the onset of stroke, the immediate transfer to a suitably equipped facility and careful screening of a computed tomographic scan of the head for signs of early infarction are necessary for the safe administration of intravenous thrombolysis. There is mounting evidence that intra-arterial thrombolysis in combination with transluminal angioplasty has even a greater potential than intravenous thrombolysis and, possibly, a lower rate of intracerebral haemorrhages. Despite doubts having been raised about the use of thrombolysis in routine clinical practice, it appears that this therapy is most effective in those patients treated with careful adherence to published guidelines.
