Smoker’s disease is an uncommon cerebrovascular disease that was first identified by a Japanese medical expert in the 1960s. Smoky disease is a chronic progressive stenosis or occlusion of major bilateral branches of the cerebral arterial ring, which leads to abnormalities in the vascular network at the base of the skull. Smog can be very dangerous and can have serious and even life-threatening consequences. It can lead to cerebral ischemia, cerebral infarction, cerebral hemorrhage, etc. Some patients may also experience seizures. The main symptoms may include dizziness, headache, weakness of limbs, loss of vision, visual field loss, memory loss, slurred speech, etc., and even cause hemiplegia and disability. If an acute attack of cerebral infarction or cerebral hemorrhage occurs, it may be life-threatening. Therefore, once smog is detected, it must be treated promptly. For the treatment of smog, the medical profession has been conducting research for more than half a century since the disease was discovered in the last century. It is now generally accepted that conservative treatment of smog is not very meaningful and surgery is the only option to treat smog. So how do you get surgery for smog? Currently, combined vascular bypass surgery is a very advanced and successful surgical procedure for the treatment of smog. The operation of combined vascular bypass surgery is such that it sends direct bypass and patching to you in the same surgery together, first anastomosing the superficial temporal artery to the middle cerebral artery to achieve immediate blood flow, and at the same time carrying out multi-factor patching to induce the formation of new blood vessels to further expand the scope of blood supply improvement and achieve more ideal results.
