What are the possible complications associated with surgery for smoker’s disease? There are three types of surgical treatments for smoker’s disease. Bypass surgery, patch surgery and combined vascular bypass surgery are generally used. Surgery has a high cure rate and is generally smooth and risk-free. Only rarely do post-surgical complications occur. What are the complications of smoldering surgery: 1. Cerebral infarction. Cerebral infarction is the most common surgical complication, which causes redistribution of blood flow in the brain after affecting the original blood flow, resulting in infarction at the surgical site or infarction at the primary site. 2. Cerebral hyperperfusion syndrome. That is, the formation of its own stable state, and the surgery has caused interference with blood flow, re-access to foreign blood flow, the formation of more obvious interference with the original blood flow, this is called cerebral overperfusion syndrome. Hyperperfusion syndrome is not that it is caused by a poor prognosis, it is a complication that normally occurs after surgery, and the brain will complete its own adaptation within about 2 weeks of surgery. 3. Cerebral hemorrhage. It is mostly seen in adults and can manifest as intraventricular hemorrhage, intracerebral hemorrhage and subarachnoid space hemorrhage due to different pathological development. Probability of surgical complications: Based on a study of 500 patient case data, it was found that the incidence of complications varied among patients with different types of surgery. The complication rates were 12.7% after direct revascularization (bypass), 12.6% after indirect revascularization (patching), and 10% after combined vascular bypass (bypass). The specific probability deviation varies according to the depth of experience of the surgeon, with a relatively high complication rate for shallow experience and a relatively low postoperative complication rate for experienced surgeons. Will there be recurrence after smoker’s disease surgery? It can be said that there is no concept of recurrence of smog, only poor surgical results or unsuccessful surgeries. Once you have smoldering disease, there is chronic progressive stenosis or occlusion of the main branches of the cerebral artery ring and the formation of a network of small smoke-like vessels at the base of the skull, and even after surgery, those narrowed and occluded vessels are still occluded. Therefore, there is no such thing as recurrence. The surgery is done by creating another new blood flow channel to supply blood to the brain through another built side branch bypass. This method does not open the blood vessels at the source, but it also keeps the patient from experiencing a lack of blood supply to the brain and is the best treatment for smog. Because postoperative complications can occur, patients should do a good job of daily care after surgery. In the first three days after surgery, they should rest in bed more often to avoid fatigue and should pay more attention to rest, and their families should pay more attention to the patient’s daily diet. In conclusion: smog surgery is treated with combined vascular bypass surgery, the probability of complications will be reduced. The procedure is also the best treatment option. The complications associated with the surgery vary from person to person, most patients do not experience complications and most complication symptoms can be treated. Patients should not worry about the health consequences of complications from the procedure. The treatment of smoker’s disease should not be left to chance and if diagnosed should be treated early to avoid safety hazards.
