This is because there are dozens of risk factors for cerebrovascular disease. Dizziness, head swelling, unstable blood pressure, and different blood pressure in both arms are all common symptoms of blood theft from the subclavian artery. Narrowing of the subclavian artery causes blood that should be supplied to the brain by the vertebral artery to flow downward to the right upper extremity, so dizziness and head swelling result from brain ischemia. The right subclavian artery is narrowed, so the blood pressure in the right arm is significantly lower than the left. Ultrasound has confirmed this. The blood flow murmur you hear yourself is exactly the murmur from the vortex caused by the narrowing of the blood vessel. We doctors also need to listen to the murmur when examining a patient. Now the patient can hear it himself, and it will be more obvious if the doctor uses a stethoscope. The presence of arterial stenosis is confirmed from the side. This condition is a must for stenting treatment. Usually arterial stenosis is divided into symptomatic and non-symptomatic. Patients with symptoms must be treated, otherwise they will further aggravate and even develop a serious cerebral infarction. The conservative treatment plan you described so far is not bad, but it is not likely to be stenosis relief! Nor is it possible to stop the progression of the stenosis. And the relationship from stenosis to vessel occlusion is not linear with a positive time correlation. Once a stenotic vessel initiates the process of occlusion, it usually takes only a few minutes. And once the vessel is occluded, in addition to the possibility of severe cerebral infarction and sequelae, it requires an occluded subclavian artery opening procedure, which is much more difficult and risky than simply implanting a stent. Subclavian artery stenting is usually safe and not very risky. Stenting in cardiac patients is usually done in emergency myocardial infarction, so the risk of cardiac stenting itself is not significant, mainly because the myocardial infarction is critical at that time! The patient’s current condition is perfectly tolerant of stenting, and I believe that after stent implantation, the patient’s condition will improve significantly, and he may even recover as normal! This is because we are solving the very problem that is causing the patient’s symptoms. My initial judgment is that only one stent is needed. There is no possibility that it will be incapacitating at all. After the stent is implanted, if no serious accidents occur, it should be possible to recover to the level before the onset of the disease. How come you can’t lift two pounds? Most likely, the surgery was done after the patient already had symptoms of cerebral infarction and limb paralysis. You remember that this surgery is to prevent future cerebral infarction and relieve the symptoms of this ischemia, and there is no immediate effect on the paralysis due to cerebral infarction that has already appeared in this time. After stenting, you can get up and move around in 24 hours. No so-called recovery time is needed. There is little to no damage to the body to speak of, only a wound smaller than a green pea. The postoperative medication situation is: aspirin + clopidogrel for 3 months after surgery; after 3 months, just keep one and take it for life. The review is very simple: within six months after surgery, it is enough to review the neck ultrasound every 3 months, and after that, it is enough to review the neck ultrasound once a year.
