Non-protected carotid artery stenting for symptomatic carotid stenosis in low resource settings

Background The use of a distal cerebral protection device during extracranial carotid artery stenting is still a matter of debate. The aim of this work was to evaluate the safety of performing carotid artery stenting procedure without the use of cerebral protection device in patients with symptomatic carotid stenosis. A retrospective study was performed during the period from September 2015 till March 2020 including 91 patients with symptomatic carotid artery stenosis. All patients were treated with a single stent type (Wall stent® - Boston scientific) without the use of cerebral protection device. Pre- and post-procedural clinical assessment with the national institute of health stroke scale (NIHSS). Post procedure brain diffusion-weighted magnetic resonance imaging (DW-MRI) if clinically indicated within 24 h was used to determine periprocedural cerebral embolization. Results A low complication rate was found as only one case (1%) showed mild deterioration in NIHSS and new acute cerebral emboli were detected with brain DW-MRI. Conclusion Carotid artery stenting can be performed safely without the use of cerebral protection device.
