Abstract 19521: Slow and Prolonged Inflations of Percutaneous Transluminal Angioplasty is as Effective as Stenting in Peripheral Vascular Interventions
Background: The benefit of stent implantation over percutaneous transluminal angioplasty (PTA) in patients undergoing peripheral vascular interventions (PVI) has not been well described. Original data supporting stents over PTA was in an era without routine atherectomy, and more recent data including chronic total occlusions (CTO) and longer lengths demonstrated no difference.
Method: 551 patients undergoing PVI were identified from January 2011 to January 2015. Success was defined by a composite improvement of ankle brachial index (ABI) to over 0.9, an ultrasound velocity of less than 250 m/s, or Rutherford classification improvement. All PTA was performed over a slow inflation over 5 minutes. A Pearson chi-square and multivariate analyses were used to determine results.
Results: 274 (49.72%) patients received PTA alone and 277 (50.28%) received stents. Although more patients with diabetes and longer lesion length were in the PTA group, stenting did not improve the individual or composite success endpoints. Even when correcting for these differences in a multivariate analysis.
Conclusion: PTA is as effective as stenting even in patients with diabetes and long lesion lengths (over 100mm). More data is necessary as drug eluting balloon angioplasty has been shown to improve patency over PTA, however the more slow and prolonged inflations in PTA may be responsible for these findings.
