Multi-center experience with intravascular lithotripsy for treatment of severe calcification during transcarotid artery revascularization for high-risk patients.

Objective: Transcarotid artery revascularization (TCAR) offers a safe alternative to carotid endarterectomy (CEA), but severe calcification is currently considered a contraindication in carotid artery stenting. This study aims to describe the safety and effectiveness of TCAR with intravascular lithotripsy (IVL) in patients with traditionally prohibitive calcific disease.

Methods: All consecutive patients who underwent TCAR+IVL from 2018-2022 at nine institutions were identified.

Initial experience with a modified "candy-plug" technique for false lumen embolization in chronic type B aortic dissection.

Background: Persistent distal false lumen (FL) perfusion after thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD) can lead to aneurysmal degeneration and an increased risk of rupture. We have presented our initial experience using a modified "candy-plug" (CP) technique for FL embolization.

Methods: From February 2021 to July 2022, we treated six patients using the modified CP technique.
