Surgery to unblock a blood vessel generally refers to either thrombus aspiration or stent implantation. It is necessary to choose the appropriate procedure for the patient’s condition. The most effective way to relieve the symptoms of vascular blockage and save the cells from necrosis due to ischemia is to unblock the blood vessel. If the thrombus is newly formed in the acute stage, thrombus aspiration can be performed to open the blood vessel. If it is a chronic lesion, aspiration is difficult to clear the thrombus, and the blood vessel can be opened by implanting a stent. Both procedures are realized by puncturing the radial artery or femoral artery for interventional therapy, which is a minimally invasive procedure with fast postoperative recovery, and the therapeutic effect has been widely certified by the clinic. The patient’s specific choice of procedure needs to be judged in conjunction with the condition of the patient and the results of the imaging, and it is recommended that the surgeon’s opinion be taken into account.
