Results of carotid artery stenting (CAS) are directly related to the experience and skills of the operator. The most dreadful complication of CAS is stroke. Analyzing the complications during the authors’ own procedures, they came to the conclusion that most, if not all, of the complications are preventable. Attention to details is crucial, and it involves having the appropriate wires, catheters, balloons, stents, and cerebral protection devices readily available.
