General Knowledge A poor quality bicycle inner tube will bulge in a ball-like fashion when inflated. Similarly, a limited or extensive bulge in the aortic wall due to weakened support for various reasons (mostly atherosclerosis), formed by the impact of arterial blood flow, is called an aneurysm. Aneurysms are not malignant tumors, but are dangerous because if they rupture and bleed, they are often life-threatening and cannot be resuscitated. AAA patients often have: smoking, hypertension, coronary heart disease, chronic obstructive pulmonary disease, chronic renal insufficiency, hyperlipidemia, diabetes, etc. Signs of the disease Often there is no obvious discomfort and is mostly detected by the doctor during physical examinations or visits for other discomforts. Some patients may have a throbbing sensation in the abdomen, and some may feel a throbbing mass on the left side of the belly button. When the aneurysm is large and compresses the surrounding organs, there may be abdominal fullness after meals, nausea and vomiting. Pain in the lower back often indicates that the aneurysm has a tendency to rupture. Ultrasound is the most common test used in the outpatient setting, and other tests include aortic spiral CT imaging and MRI angiography and angiography. The classical and effective treatment for this condition is surgery. Endovascular treatment of abdominal aortic aneurysms is a new technique and option that has been developed in the last decade or so. Its greatest advantage is that it is less invasive and does not require an open abdomen. It is increasingly preferred or even preferred by patients and physicians because of its minimally invasive features, but it is more expensive. Whether the patient can undergo this treatment depends on the specific anatomy of the tumor and is not applicable to all patients. Self-care 1. Quit smoking. 2. Strictly control blood pressure, regulate emotions and avoid great joy and sadness. 3. For those who suffer from chronic obstructive pulmonary lesions, attention should be paid to keeping warm and cold during the alternating seasons, reducing the triggering factors of lung infection, and avoiding violent coughing. 4. avoid constipation and various factors that may cause increased pressure in the thoracic and abdominal cavities. 5. Avoid abdominal compression and collision. Precautions Preoperatively, practice relieving hands and defecation in bed. Practice deep breathing and effective coughing before surgery to facilitate postoperative elimination of respiratory secretions and full lung expansion. Open patients generally cannot eat and drink for about 3 days after surgery, and can only gradually resume eating and drinking after exhaustion. Encourage early postoperative limb activities in bed, and get out of bed as soon as the condition permits.
