Specific steps: After local anesthesia, use a very fine puncture needle to enter the femoral artery (femoral artery/radial artery), then insert a contrast catheter (less than 2 mm in diameter) to reach the cervical blood vessel, and inject contrast agent through the catheter for angiography to understand the degree of blood vessel blockage. This process is called cerebral angiography.
Patients with acute cerebral infarction can be recanalized with thrombolytic drugs through catheter, which is called arterial thrombolysis.
Those who need stent treatment also send the stent into the blood vessel through the neck and cerebrovascular, and release the stent after reaching the lesion.
After interventional examination and treatment, it is necessary to stay in bed for several hours to repair the blood vessels in the thigh before resuming daily activities.
During the examination and treatment, the patient has only a brief mild pain and does not need special treatment. Therefore, interventional therapy does not require surgery, with little trauma and quick recovery!
