Anatomic and hemodynamic evaluation of percutaneous transluminal angioplasty
Insights
Balloon angioplasty for lower extremity arteries shows limited long-term success. Femoropopliteal angioplasty is not durable, while iliac artery angioplasty durability needs more study.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
Background:
- Lower extremity arterial disease significantly impacts patient mobility and quality of life.
- Balloon angioplasty is a common endovascular intervention for treating these stenotic lesions.
Purpose of the Study:
- To evaluate the long-term durability and success rates of balloon angioplasty in the lower extremities.
- To compare the outcomes of iliac artery angioplasty versus femoropopliteal angioplasty.
Main Methods:
- Prospective observation of 29 out of 34 patients undergoing lower extremity balloon angioplasty over two years.
- Hemodynamic measurements and arteriograms performed pre-procedure, immediately post-procedure, and at three-month intervals.
- Late follow-up arteriograms for selected patients.
Main Results:
- Immediate technical success was 93%, but early hemodynamic improvement was only 62%.
- At a mean follow-up of nine months, overall continued success was 48%.
- Late failure rates were 18% for iliac artery procedures and 50% for femoropopliteal procedures.
Conclusions:
- Femoropopliteal balloon angioplasty demonstrates poor long-term durability.
- The durability of balloon angioplasty for iliac artery disease requires further investigation.
Abstract:
Of 34 balloon angioplasties of the lower extremity performed during a two year period, 29 were observed for three to 21 months. Hemodynamic measurements were performed preangioplasty, immediately postangioplasty and at three month intervals thereafter. Immediately, postangioplasty arteriograms were performed upon all patients. Late follow-up arteriograms were obtained for selected patients. Immediate anatomic success was achieved in 93 per cent of procedures, but early hemodynamic improvement occurred in only 62 per cent of the angioplasty procedures. At a mean follow-up time of nine months, continued success was noted in only 48 per cent of the procedures. Late failure with iliac artery procedures was demonstrated in only 18 per cent of the patients, while, in femoropopliteal angioplasty, late failure occurred in 50 per cent of the procedures. The results of this study and of others indicate that femoropopliteal balloon angioplasty in not a durable procedure. The durability of iliac artery angioplasty requires further evaluation.
