Effect of balloon angioplasty in femoropopliteal arteries assessed by intravascular ultrasound

Abstract

Vascular damage is common following PTA. Lumen gain is mainly due to vessel expansion and, to a lesser extent, to a decrease in plaque area.

Intravascular Ultrasound and Histology in In Vitro Assessment of Iliac Artery Angioplasty

“…Both the lumen area and the vessel area at the target site increased significantly more than the mean values obtained from all cross-sections. In contrast, a slight increase in plaque area was seen, probably caused by a better detection of plaque after PTA; these findings correspond with studies in both coronary and peripheral arteries [3,5,6,11,13,14] (Table 4). However, in two other studies a different explanation has been proposed for the increase in lumen area after PTA.…”

“…In vitro studies performed with IVUS in atherosclerotic arterial segments have proven that the technique is reliable for documenting lesion morphology and quantifying the size of the vessel lumen and the extent of plaque [8 -10]. Furthermore, IVUS is able to assess the morphologic and quantitative effects of balloon angioplasty (PTA) [11][12][13][14]. To date, no systematic study has investigated in vitro the ability of IVUS to assess the effects of PTA in the iliac artery.…”

High-Grade, Non-Flow-Limiting Dissections Do Not Negatively Impact Long-term Outcome After Paclitaxel-Coated Balloon Angioplasty: An Additional Analysis From the THUNDER Study

“…13,14 In the FemPac study, 15 the rate of dissections was lower (~30% for both coated and uncoated balloons). In THUNDER, dissections occurred in~50% of the patients in each of the two treatment groups.…”

Usefulness of the “Non-Slip Element” Percutaneous Transluminal Angioplasty Balloon in the Treatment of Femoropopliteal Arterial Lesions

“…The main drawback of balloon angioplasty is vessel dissection, which occurs in ~80% of cases. 11,12 Severe dissection requires repeat revascularization and has an adverse effect on long-term patency. 10 Nitinol stent implantation is an alternative to balloon angioplasty, and midterm clinical outcomes of nitinol stenting were superior to those of balloon angioplasty for the treatment of femoropopliteal lesions.…”
