What are the symptoms of abdominal aneurysm and how to diagnose it

What are the symptoms of an abdominal aneurysm? How is it diagnosed?

Symptoms of abdominal aortic aneurysms, in fact, most patients have no symptoms, often due to physical examination and accidental discovery for other reasons. The typical abdominal aortic aneurysm is a bulging mass that beats sideways and forward and backward, and half of the patients are accompanied by vascular noise. A small number of patients have compression symptoms, and the above-mentioned abdominal fullness and discomfort are common.

Symptoms of abdominal aortic aneurysm mainly indicate the need for surgical treatment, and its symptoms mainly include:

1. Pain: It is a common symptom before rupture, mainly located around the umbilical cord and in the upper and middle abdomen. When the aneurysm invades the lumbar spine, there may be lumbar pain. If there is severe pain in the abdomen or waist recently, it usually indicates that the tumor is on the verge of rupture.

2. Rupture: Patients with acute rupture suddenly experience severe back pain, accompanied by shock, and may even die before admission to the hospital. If the peritoneum ruptures, bleeding is limited to hematoma, and abdominal pain and hemorrhagic shock may last for hours or days, but the hematoma may usually rupture again into the peritoneal cavity and cause death. Tumors can also rupture into the inferior vena cava, resulting in aortovenous fistulas and heart failure. Tumors occasionally rupture into the duodenum, causing gastrointestinal bleeding.

3. Other serious complications: Tumors occasionally cause acute thrombosis, which can lead to lower extremity arterial embolism. Duodenal pressure can cause intestinal obstruction, and inferior vena cava pressure obstruction can cause peripheral edema.

Abdominal aortic aneurysm must be diagnosed before it can be treated. You can suspect abdominal aortic aneurysm based on medical history and a mass around the umbilicus or in the upper middle abdomen, sometimes with mild tenderness, which may be accompanied by acute or chronic lower limb ischemia symptoms, and some patients may hear abdominal vascular noise and tremors. Further color ultrasound examination, CTA or MRA diagnosis can be established through examination. CTA can be used as a means of first clear diagnosis of abdominal aortic aneurysm.
