Abstract

Objective: Mo. Ma Ultra (Mo. Ma) is used during carotid artery stenting (CAS) and, in two cases, we experienced difficulties withdrawing the stent delivery system. Here we report the mechanism and procedures that should be performed for safe withdrawal of the system.
Case presentation: Representative case 1: An 81-year-old male patient with symptomatic carotid stenosis who underwent CAS using Mo. Ma. During the operation, we encountered issues with withdrawing the stent delivery system.
Conclusion: The cause of difficulties in withdrawing the stent delivery system in CAS using Mo. Ma is the stent tip getting caught in the outlet port of Mo. Ma. The stent system can be safely withdrawn by resheathing the outer sheath of a Precise stent accurately.
