Revascularization therapy: Since the occurrence of stroke is often associated with thrombus formation in cerebral arteries, embolization therapy can be used in the hyperacute phase of stroke, using an embolization stent to reach the diseased vessel through a microscopic catheter to remove the thrombus and recanalize the vessel. If it is purely a thrombotic component or embolic material, the thrombectomy stent is not implanted in the body; if there is a stenosis or vascular entrapment, the thrombectomy stent or other stent implantation is required to avoid re-occlusion or thrombus re-formation after thrombus removal and to improve the recanalization rate. It is important to buy time: different treatment strategies are used at different times of onset. Within 4.5 hours of infarction in the cerebral hemisphere, intravenous thrombolysis can be performed first. If intravenous thrombolysis is not effective or if there is evidence of cerebrovascular occlusion, subsequent reliance on arterial thrombolysis is used to recanalize the vessel. If the onset is outside of 4.5 hours and within 8 hours and there is the possibility of large vessel pathology, direct vascular imaging or direct cerebral angiography can be performed to recanalize the vessel if cerebral artery occlusion is present. For posterior circulation strokes, the time can be relatively longer. Because the consequences of posterior circulation stroke with conventional treatment are extremely poor, a turnaround may exist only with better recanalization therapy. The duration of posterior circulation can therefore be extended to 24 hours. For units where thrombolysis does not exist, if within the time window of onset, intravenous thrombolysis may be used first, and then rapid transfer to a hospital in a condition for thrombolysis can be performed using an ambulance. Time is too important: In hyperacute stroke treatment, a large number of neurons die every second, which increases the chance of corresponding poor prognosis if time is delayed. According to Changhai Cerebrovascular Center, most of the time is often wasted on preoperative communication with families; for example, sometimes when it comes to the risk of embolization treatment, some families even have to wait for other families to make a decision together, and finally delay the treatment. In order to save time, Changhai Cerebrovascular Disease Center adopts the model of examination and treatment first and pay later, with a high degree of integration of cerebrovascular medicine and surgery as one, forming a professional treatment team to receive treatment quickly and save patients first, which greatly shortens the golden time before treatment. Related points: 1. Hyperacute stroke can be treated with embolization; 2. Both doctors and patients’ families should have the concept of golden time.
