VEITH 2023 | Vikram S. Kashyap: Do pre-expansion, post-expansion during TCAR therapy increase adverse events
Extracranial carotid artery stenosis is a major cause of atherosclerotic stroke. Transfemoral carotid artery stenting (TF-CAS) is an important therapeutic procedure for carotid artery stenosis. The balloon dilatation strategies during its treatment are preexpansion only (PRE), postexpansion only (POST), and preexpansion + postexpansion (PRE + POST). Concerns have been raised about higher neurological risk and hemodynamic instability associated with POST and PRE + POST during TF-CAS. Studies have shown that post dilatation for TF-CAS increases the risk of stroke by 2.4-fold and increases the risk of hemodynamic instability by 3.8-fold, which can lead to increased myocardial infarction (MI), LOS, and mortality. Transcarotid artery revascularization (TCAR) bypasses the manipulation of the device through the aortic arch and across the diseased segment, providing better embolic protection. Whether performing balloon dilatation during TCAR also results in the above adverse events is not yet known.At the recent 50th International Congress on Vascular and Endoluminal Vascularization (VEITH 2023), Professor Vikram S. Kashyap from the Cleveland Medical Center analyzed the results of performing PRE or POST or PRE+POST balloon dilation strategies during TCAR.
