We examine the problems arising when training residents/fellows (RFs) initiate the learning of diagnostic cervicocerebral angiography (DCCA) and describe the steps on how to facilitate the learning process while avoiding complications. The risk of permanent neurological deficit as a result of DCCA ranges from 0.3–0.5%. Factors that correlated with complications include the following: the history of cerebral infarction, infusion of a large amount of contrast medium, a prolonged fluoroscopic time (>80 min) and the efficiency of training received. These findings suggest that the neurological morbidity depends largely upon the technique of catheterization of the patient. In order to reduce the complications arising from the lack of training, a personalised mentorship with a careful supervision of trainees is necessary. To ensure a good patient outcome, a decreased procedural time, awareness of complications at every step of the procedure and their avoidance, as well as the provision of good quality images is necessary. A mentorship program with a close supervision of the RFs is also one of the prerequisites for obtaining a good result.
