Percutaneous Transluminal Angioplasty (PTA) with Wallstent for Internal Carotid Artery Stenosis. A Case Report

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Vascular Medicine

Background:

• A 67-year-old male with a history of myocardial infarction required evaluation for internal carotid artery stenosis prior to heart surgery.
• Preoperative studies revealed severe stenosis of the right internal carotid artery, despite the absence of neurological symptoms.

Purpose of the Study:

• To assess the efficacy of percutaneous transluminal angioplasty (PTA) with self-expanding stent placement for severe internal carotid artery stenosis.
• To manage carotid artery stenosis in a patient undergoing preparation for coronary artery bypass grafting (CABG).

Main Methods:

• Percutaneous transluminal angioplasty (PTA) was performed using a self-expanding stent to treat the stenotic right internal carotid artery.
• Angiographic assessment was conducted immediately post-procedure and at a three-month follow-up.

Main Results:

• The internal carotid artery stenosis improved significantly from 75% to 11% immediately after stenting.
• Mild restenosis to 16% was observed at the three-month follow-up.
• The stenting procedure was completed without any complications.

Conclusions:

• PTA with stenting is an effective treatment for severe internal carotid artery stenosis in patients with cardiovascular disease.
• Successful management of carotid artery stenosis facilitated the subsequent uneventful coronary artery bypass grafting (CABG) surgery.
• This case highlights the importance of addressing asymptomatic carotid stenosis in patients undergoing major cardiac procedures.
