Summary

Minimally invasive endoscopic thoracic sympathectomy offers a safe and effective treatment for severe angina pectoris in patients ineligible for traditional procedures. This approach significantly improves symptoms and exercise capacity with no major complications.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Minimally Invasive Procedures

Background:

  • Open surgical sympathectomy effectively treats severe angina pectoris but has high morbidity and mortality.
  • A minimally invasive endoscopic technique for sympathectomy has shown promise for palmar hyperhidrosis.

Purpose of the Study:

  • To evaluate the efficacy and safety of minimally invasive endoscopic thoracic sympathectomy for severe angina pectoris in patients unsuitable for conventional treatments.

Main Methods:

  • Endoscopic thoracic sympathectomy was performed on 43 patients with severe angina pectoris.
  • Patients were ineligible for coronary artery bypass grafting or percutaneous transluminal coronary angioplasty.

Main Results:

Related Experiment Videos

  • No mortality or severe complications were observed.
  • 19 patients (44%) were symptom-free, 22 (51%) improved, and 2 (5%) were unchanged.
  • Significant reductions in anginal attack frequency, nitroglycerine use, and ST-segment depression, along with increased exercise capacity.

    • Conclusions:

    • Minimally invasive endoscopic thoracic sympathectomy is a safe and effective treatment for severe angina pectoris in select patients.
    • This technique provides significant symptomatic relief and functional improvement with a low complication rate.
