Abstract
PURPOSE
In some patients, revascularization is not possible or is not effective. For these, percutaneous deep vein arterialization (p-DVA) could be considered an alternative treatment. The aim of this study is to evaluate the long-term results of an intravascular ultrasound (IVUS)-guided technique that has only one percutaneous access.
MATERIALS AND METHODS
This is a prospective monocentric study on 18 no-option CLTI limbs treated with an IVUS-guided p-DVA. The primary outcome measures are: the freedom from major adverse events (MAEs) and survival at 30 days; limb salvage and amputation free survival (AFS) at 30 days, 6 months, 12 months and 24 months. The secondary outcome measures are: procedural success, survival, patency and wound healing.
RESULTS
We treated 14 patients with no-option CLTI, carrying out 18 p-DVA. Median age was 74,4 years (60-87). All these patients had a previous failed angioplasty of the tibial and foot arteries. Procedural success rate, defined as the establishment of arterial flow into the venous system of the foot, was 100%. No deaths and MAEs recorded at 30 days. Survival was 100%, 83.4% and 77.8%; limb salvage was 88.9%, 77.8% and 77.8%; AFS was 88.9%, 61.1% and 55.6% at 6, 12 and 24 months. Complete wound healing was 18.7% at 6 months, 80.0% at 12 months and 100% at 24 months.
CONCLUSION
Based on these results, the IVUS-guided p-DVA seems to be safe and effective for no-option CLTI patients, with no mortality related to the intervention, an acceptable limb salvage rate and amputation free survival.
