Aortic dissection rarely presents solely as lower limb ischemia, often leading to misdiagnosis as embolism. Prompt diagnosis requires considering dissection when embolectomy fails and angiography reveals specific vascular abnormalities.

Area of Science:

  • Vascular Surgery
  • Diagnostic Imaging
  • Cardiovascular Disease

Background:

  • Aortic dissection is a serious cardiovascular condition.
  • Lower limb ischemia can be an uncommon primary symptom of aortic dissection.

Observation:

  • Two cases are presented where aortic dissection mimicked limb ischemia.
  • Patients underwent attempted embolectomy prior to correct diagnosis.

Findings:

  • Diagnosis of aortic dissection should be suspected when embolectomy is unsuccessful in removing thrombus.
  • Angiography may reveal spiral lucencies in large vessels or non-filling of major arterial branches.

Implications:

  • Pre-operative angiography is crucial for accurate diagnosis in suspected cases.
