The conditions required for cerebrovascular stenting include meeting the indications without contraindications, which should be comprehensively evaluated by the doctor in conjunction with the actual situation of the patient.
1. Indications: (1) Non-disabling ischemic cerebrovascular disease that has occurred within 6 months in the area responsible for the blood supply of the diseased vessel, if angiography suggests that the stenosis of the diseased artery is more than 50%, or non-invasive angiography suggests that it is now more than 70%.
(2) Patients without neurologic localization symptoms may be considered for stenting if angiography suggests a luminal stenosis of more than 60% or noninvasive angiography suggests a stenosis of more than 70%, and if pharmacologic therapy is ineffective.
2. Contraindications: (1) Patients with intracranial hemorrhage within 3 months; having had a cardiac infarction or large cerebral infarction within 3 weeks; accompanied by intracranial aneurysm or acute lesions of blood vessels that cannot be treated in advance or at the same time; and active bleeding in the gastrointestinal tract.
(2) Having uncontrollable hypertension; inability to use heparin and antiplatelet drugs; allergy to contrast agents; having cardiac, renal, and other important organ insufficiency; having a tortuous arterial course that makes the procedure difficult; and having an expected survival of less than 2 years.
Whether a patient is able to undergo cerebrovascular endoprosthesis implantation needs to be professionally and comprehensively evaluated by a doctor, and it is recommended that he or she should seek medical treatment in a timely manner and under the guidance of a doctor.
