What is an abdominal aneurysm and what are the symptoms

The appearance of an aneurysm always causes panic. Aneurysms that have not ruptured and are bleeding usually require laboratory tests to diagnose. So what is an abdominal aneurysm? What are the symptoms?

Abdominal aortic aneurysm is a local or widespread permanent dilation or expansion formed due to damage to the middle layer structure of the artery, which makes the arterial wall unable to withstand the impact pressure of blood flow.

Most patients have no symptoms and are often discovered accidentally for other reasons. The typical abdominal aortic aneurysm is a bulging mass that pulsates on one side and back and forth, and half of the patients are accompanied by vascular noise. A few patients have compression symptoms, and the above-mentioned abdominal fullness and discomfort are common.

Symptomatic abdominal aortic aneurysms mainly include:

1. Pain: Pain is a common clinical symptom of abdominal aortic aneurysm. About one-third of patients experience pain. The pain is mainly located around the abdomen and umbilicus, ribs or waist. The nature of the pain can be dull pain, swelling pain, stabbing pain or knife-like pain.

2. Compression symptoms: As the abdominal aortic aneurysm continues to expand, corresponding symptoms may compress adjacent organs, which is more common clinically.

3. Embolism symptoms: Once the blood clot in the abdominal aortic aneurysm breaks off, it will turn into an embolism, blocking the organs or limbs supplied by blood and causing corresponding acute ischemic symptoms.

4. Abdominal pulsating mass: This is the most common and important sign of abdominal aortic aneurysm. Most patients are aware of the beating around the heart or umbilical cord. About one in six patients reported that their heart fell into the abdominal cavity. This pulsation is particularly prominent in the supine position and at night. The mass is mainly located in the left abdomen, with persistent and multidirectional pulsation and expansion.

5. Rupture symptoms: Abdominal aortic aneurysm rupture is an extremely dangerous surgical emergency with a mortality rate of 50% to 80%. The load pressure of the Laplace tube wall is proportional to the radius of the tumor. The larger the tumor diameter, the greater the risk of rupture.

Abdominal aneurysms are usually abdominal aortic aneurysms, which are usually accompanied by pain and rupture symptoms. Early diagnosis and treatment can reduce the harm of the disease to us.
