Insights

External carotid artery (ECA) stenting effectively treated limb-shaking transient ischemic attacks (TIAs) in a patient with severe carotid disease. This endovascular approach offers a viable alternative for managing complex carotid artery stenosis.

Area of Science:

  • Vascular Surgery
  • Neurology
  • Interventional Cardiology

Background:

  • The external carotid artery (ECA) is a key collateral source for cerebral blood flow, particularly during internal carotid artery (ICA) compromise.
  • Endovascular research has predominantly focused on the ICA, with limited attention to the ECA.
  • Limb-shaking transient ischemic attacks (TIAs) are an uncommon symptom of carotid artery disease, characterized by repetitive limb movements.

Observation:

  • A case involving an 80-year-old male with bilateral ICA and contralateral ECA occlusion presented with limb-shaking TIAs.
  • The patient exhibited significant stenosis in the right ECA as the cause of his symptoms.
  • The patient had bilateral internal carotid artery and contralateral external carotid artery occlusion.

Findings:

  • Percutaneous revascularization of the stenosed right ECA was successfully performed using angioplasty and stenting.
  • At 12-month follow-up, the patient remained neurologically stable with complete resolution of TIAs.

Implications:

  • External carotid artery (ECA) stenting is a feasible treatment option for limb-shaking TIAs.
  • This endovascular strategy is particularly beneficial for patients with contralateral carotid stenosis, compromised circle of Willis, or significant comorbidities.
  • ECA stenting presents a reasonable alternative to open surgical repair in select patient populations.
