简介:
急性脑栓塞
Acute cerebral embolism is acute cerebral infarction, also known as “stroke”. It is a neurological dysfunction in the corresponding brain area due to degeneration and necrosis of nerve cells in the area of blood supply in the brain as a result of acute interruption of blood flow in the arterial blood vessels supplying the brain. Common etiologies and pathogenesis include atherosclerosis, cerebral embolism, arteriole occlusion, and brain diseases with definite etiology causing cerebrovascular damage, such as vasculitis and hereditary disorders.

  • 症状

    "Most of them have an acute onset during activities, without prodromal symptoms.

    The onset is sudden, peaking in seconds to minutes, with focal neurological impairments such as hemiplegia and aphasia. Cerebral artery occlusive syndrome includes unilateral hemiplegia (severe), lateral numbness (loss of sensation), homonymous hemianopia, aphasia, apraxia, vertigo, diplopia, oculomotor palsy, ataxia, crossed paralysis, pupillary abnormalities, quadriplegia, difficulty in eating and swallowing, and consciousness disorder."
  • 风险

    Whether an acute cerebral embolism is life-threatening or not depends mainly on the infarct size and location and the presence of serious complications. A small lacunar infarct is generally not life-threatening. However, massive cerebral embolism, such as a relatively large area embolism in the cerebral hemisphere or a large area embolism in the brainstem and cerebellum, may be immediately life-threatening, possibly due to increased intracranial pressure or due to brain herniation. Especially, the brain stem infarction, if large in size, may lead to respiratory and circulatory disorders, as well as consciousness disorder and even coma. It tends to be complicated with pulmonary infections, urinary tract infections, decubitus ulcers or deep vein thrombosis of the lower extremities, all of which may directly threaten the patient’s life. Therefore, acute cerebral embolism is life-threatening.
  • 诊断

    "Most of them have an acute onset during activities, without prodromal symptoms. It can be highly suspected by the patient's symptoms.

    At the same time, the clinical diagnosis can basically be made based on the previous medical history, such as previous history of underlying diseases of embolic origin such as heart disease, atherosclerosis, severe fractures or complicated embolism of other organs.

    The diagnosis can be established by CT, MRI and perfusion imaging, DSA and other imaging examinations."

Catheter thrombectomy

Catheter thrombectomy is a procedure in which an aspiration catheter is delivered to the proximal end of an intracranial thrombus and the thrombus is extracted directly from the body through the catheter by negative pressure aspiration at the proximal end of the catheter. Or the catheter is pulled out of the body along with the thrombus when negative pressure suction is applied, to unblock the occluded vessels and restore blood flow.

Stent thrombectomy

Stent thrombectomy is a procedure in which a stent is pulled out of the body along with the thrombus after the stent is delivered inside the thrombus through a microcatheter with the support of angiography, and then is released and fully opened to be embedded with the thrombus, to unblock the occluded vessels and restore blood flow.
