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
Evaluation
- 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]
