Abdominal aortic aneurysm

Alternative names:

aneurysm - aortic

Symptoms:

• abdomen hernia or mass, midline, pulsating (rhythmic throbbing), with tenderness to touch
• pulsating sensation in the abdomen
• pain in the abdomen
  • severe, sudden, persistent or constant
  • not colicky or spasmodic
  • may radiate to groin, buttocks, or legs
  • pain may begin suddenly

• abdominal rigidity
• pain in the lower back
  • severe, sudden, persistent, may radiate

• paleness
• rapid pulse
• dry skin/mouth
• excessive thirst
• anxiety
• nausea & vomiting
• lightheadedness occurs with upright posture
• fainting occurs with upright posture
• sweating, excessive
• skin, clammy
• fatigue (tiredness or weariness) developing recently
• heartbeat sensations
• rapid heart rate(tachycardia) when rising to standing position
• impaired ability to concentrate
• shock
• abdominal mass

Note: Aneurysms may develop slowly over many years and often have no symptoms. If the aneurysm expands rapidly, tears open (ruptured aneurysm), or blood leaks along the wall of the vessel (aortic dissection), the above symptoms may develop suddenly.

Signs and tests:

Listening to the abdomen with a stethoscope (auscultation) shows a "blowing" murmur over the aorta or a "whooshing" sound (bruit). Physical examination of the abdomen is performed. If a rupture is suspected, physical examination for signs of blood loss (hypovolemia) and an evaluation of lower extremity pulses and circulation are performed.

Abdominal aortic aneurysm may show on these tests:

• abdominal X-ray
• abdominal ultrasound
• MRI of abdomen
• CT scan-abdominal
• angiography of aorta

A CBC may indicate loss of blood.
