Clinical Causes: Aging: The risk increases as people grow older, especially over 60. Atherosclerosis: The buildup of fatty deposits in the arterial walls weakens the vessel wall. Genetic Factors: Family history of aneurysms increases risk. Hypertension: High blood pressure puts extra stress on the arterial walls. Smoking: Smoking cigarettes significantly elevates the risk of aneurysm formation and rupture. Trauma: Sudden injury to the abdomen can cause aneurysm rupture. Infections: Occasionally, infections can weaken the arterial wall. Connective Tissue Disorders: Conditions like Marfan syndrome or Ehlers-Danlos syndrome can predispose to aneurysms.

Key Symptoms: Sudden, severe abdominal or back pain that may radiate to the groin or legs. A feeling of pulsation or awareness of a throbbing mass in the abdomen. Signs of shock such as rapid heartbeat, low blood pressure, and sweating. Nausea or vomiting. Lightheadedness or fainting episodes. Decreased or absent peripheral pulses if blood flow is compromised.

Diagnosis Path: Ultrasound: A quick, non-invasive test that can detect aneurysms and their rupture. Computed Tomography (CT) Scan: Provides detailed images of the aorta and reveals the extent of rupture. Magnetic Resonance Imaging (MRI): An alternative imaging option, often used when concerns about radiation exposure exist. Physical Examination: Detection of a pulsatile abdominal mass and signs of shock.

Treatment Protocols: Emergency Surgery: The most common and critical approach involves repairing the aneurysm via open surgical repair or endovascular aneurysm repair (EVAR). Blood Transfusion: To replace lost blood and stabilize blood pressure. Intensive Care: Postoperative management in an intensive care unit to monitor vital signs and organ function. Supportive Care: Managing pain, preventing infections, and controlling blood pressure to reduce strain on the repaired vessel.
