Infrarenal Abdominal Aortic Aneurysm, Ruptured: Causes, Symptoms, and Diagnosis

Infrarenal abdominal aortic aneurysm (AAA) refers to the abnormal dilation of the lower segment of the aorta, which passes through the abdomen. When this aneurysm ruptures, it can lead to life-threatening complications. Understanding the causes, symptoms, and diagnosis of a ruptured infrarenal AAA is crucial for timely medical intervention.

Causes:

1. Age: Advanced age is a significant risk factor for developing an infrarenal AAA.
2. Smoking: Tobacco use greatly increases the likelihood of aneurysm formation and rupture.
3. Genetics: A family history of AAA can contribute to an individual's susceptibility.
4. High blood pressure: Uncontrolled hypertension puts excessive strain on the arterial walls, making them more prone to weakening.

Symptoms:

• Pain: A sudden, severe abdominal or back pain is a common symptom of a ruptured infrarenal AAA. The pain may radiate to the groin or legs.
• Hypotension: A sudden drop in blood pressure can occur due to internal bleeding, leading to dizziness, lightheadedness, and even loss of consciousness.
• Pulsating mass: In some cases, a palpable pulsating mass may be felt in the abdomen, indicating the presence of an AAA.

Diagnosis:

If a ruptured infrarenal AAA is suspected, immediate medical attention is crucial. The following diagnostic procedures are commonly used:

1. Physical examination: A thorough physical examination is conducted to assess the patient's vital signs, including blood pressure, heart rate, and presence of a pulsating mass.
2. Imaging tests: Ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI) may be performed to visualize the aneurysm and determine the extent of the rupture.
3. Lab tests: Blood tests, such as complete blood count (CBC), may be conducted to evaluate the patient's overall health and detect any potential complications.
