Background

  • The most common visceral arterial aneurysm, and the third most common abdominal aneurysm after the aorta and iliac vessels
  • The incidence of splenic artery aneurysms on CT is 0.8%[1]

Clinical Features

  • Typically asymptomatic as most are incidental findings on CT
  • Can cause epigastric/abdominal pain and hemodynamic instability if ruptured

Differential Diagnosis

  • Calcified left adrenal haematoma
  • Other causes of hemoparitoneum if ruptured

Diagnosis

  • Initial FAST exam may show fluid in left upper quadrant if ruptured aneurysm
  • CTA Abdomen/Plevis is the gold standard[2]

Management

  • Emergent laparotomy or endovascular ablation for ruptured aneurysm

Disposition

  • Any size in symptomatic patients, cirrhotic patients undergoing liver transplant, patients with α-1 antitrypsin deficiency, and patients who are pregnant or of childbearing age requires consultation with a vascular surgeon for ligation or embolization
  • Greater than 2cm: Requires consult with a vascular surgeon for ligation or embolization[3]
  • Less than 2cm: Discharge with follow up with PCP or vascular surgeon for surveillance scans at six months and then every 1-2 years[4][1]
