Cutting balloon angioplasty (CBA) versus conventional balloon angioplasty (PTA) in the pre-dilatation of carotid artery stenosis: our preliminary experience.

| Abstract |
A retrospective study was carried out to evaluate the efficacy and safety of cutting-balloon angioplasty (CBA) for the predilatation of tight fibrocalcified carotid stenosis before carotid artery stenting (CAS). We also compared the intraprocedural results of CBA with those of conventional percutaneous transluminal angioplasty (PTA) in terms of postdilatation rate. The study population was composed of 32 patients who underwent CAS requiring predilatation before stent implantation. In detail, predilatation was performed by using a conventional balloon (PTA) in 14 patients (group A) and a cutting balloon (CBA) in 18 patients (group B). Intraprocedural and periprocedural mortality, major and minor procedural and neurologic complications, arterial damage, and embolic debris found in the distal filter were recorded. We statistically compared the rate of postdilatation obtained in the two groups. Technical success was obtained in 100% of the cases. No death, major neurologic or periprocedural complications, or arterial damage were recorded in either group. Minor neurologic reactions were recorded in 1 patient from group A (4%) and in 1 patient from group B (3%). Embolic debris was found in the distal filter in 2 patients from group A (8%) and in 3 patients from group B (10%). Postdilatation was necessary in 14 patients from group A (100%) and in 9 patients from group B (50%) (p < 0.05). Although limited to a small number of patients, compared with PTA, CBA seems to be a safe and effective procedure for the predilatation of tight fibrocalcified carotid stenoses before stent placement and may decrease the need for postdilatation in this patient population.
