Many patients and family members diagnosed with abdominal aortic aneurysm are worried that “if it ruptures acutely, will their lives really be on the line?” “The risk of surgery is very high, and if the surgery fails or there are complications, will it be the same?” Here’s what you need to know about acute rupture and the risks of surgery. A ruptured abdominal aortic aneurysm will generally be one of the following (1) forward breaking into the abdominal cavity, a large amount of blood loss into the abdominal cavity can quickly lead to shock or even death; (2) backward breaking into the peritoneum, forming a local hematoma, the peritoneum can often limit the continuation of bleeding, in this case the patient often has the opportunity to reach the hospital for emergency surgery to save lives. However, the complications and risks of emergency surgery are inevitably higher than those of elective surgery when detected early. (3) Rupture into the intestine and rupture into the lower vena cava is still considered extremely risky, but surgery can still be sought to gain a life-saving opportunity. Is surgery risky? In hospital centers with extensive surgical experience, the success rate of surgery is high, but with surgery comes risk. After all, abdominal aortic aneurysm repair surgery is one of the major surgeries in vascular surgery, and these risks include cardiovascular accident, paraplegia, intestinal and lower limb ischemia, as well as stent endoleaks, displacement, and infection. Endoleak is the continued flow of blood into the tumor cavity by various routes after overlapping stent implantation. The specific risks and complications need to be evaluated by a specialist preoperatively depending on the patient’s specific situation. In addition, the risks of emergency surgery are necessarily greater than those of elective surgery. One of the most important things to note about the risks of surgery is that the risk of abdominal aortic aneurysm rupture is always present in all aspects of the procedure, such as during hospitalization, during transport to the operating room, before surgery, and during surgery. After successful abdominal aortic aneurysm surgery, it is not a one-time event. activity, blood flow abnormalities, etc. Routine imaging review includes CTA or ultrasound to observe whether the blood flow is smooth, the position of the artificial vessel or stent, whether there is internal leakage, stent infection, stenosis, etc. It is usually 1 week, 3 months, 6 months, 1 year after surgery, and annually thereafter. What to do when there is obvious discomfort: return to the hospital or seek vascular surgery consultation promptly if there are episodes of abdominal pain, back pain, persistent high fever, gastrointestinal bleeding, lower limb ischemia, etc. during the out-of-hospital period.
