# Recurrent carotid artery stenosis successfully and safely treated with drug-coated balloon angioplasty under flow reversal

## TL;DR

A drug-coated balloon angioplasty successfully treated recurring carotid artery narrowing in a patient with no further issues after 16 months.

## Contribution

Demonstrates successful treatment of recurrent carotid artery restenosis using drug-coated balloon angioplasty under flow reversal.

## Key findings

- Drug-coated balloon angioplasty resolved the lesion and improved symptoms.
- Patient remained asymptomatic with no restenosis for 16 months post-treatment.

## Abstract

Carotid artery restenosis after index carotid artery revascularization reduces its stroke prevention benefit. A 73-year-old woman presented with recurrent right carotid artery restenosis following two carotid endarterectomies with patch angioplasty and in-sent restenosis after subsequent transcarotid artery revascularization. We performed in-stent paclitaxel-coated balloon angioplasty under flow reversal with resolution of the lesion on imaging and improvement in symptoms. Patient remains asymptomatic with no evidence of restenosis 16 months after treatment.
