A perspective of percutaneous transluminal angioplasty

PTA is a relatively new procedure which is still evolving. More technical improvements are needed. Stiffer balloon plastics and devices to measure arterial wall compliance during balloon inflation are predicted to lead to better long-term success rates. Increasing case numbers provide greater expertise and subsequent refinements in performance and case selection. These factors will lead to improved statistics. Other features of overall patient care must be considered also. The procedure is easy for patients to tolerate, and they can return to activities and work in three or four days. The overall cost is much cheaper than surgery, even at a conservative success rate of 65 percent. There is minimal risk and morbidity, and virtually no mortality. PTA can be repeated if the lesion recurs. Severe complications are rare and almost always surgically treatable. If PTA fails to achieve success, a traditional surgical procedure can be performed. Percutaneous transluminal angioplasty is an important therapeutic alternative to traditional medical and surgical treatment for occlusive arterial disease. It can save legs, veins, time, and money. We need to refine and accurately record the use of this procedure. Total cooperation among clinicians, surgeons, and radiologists is essential for proper utilization of PTA.
