SECONDARY outcome

Timeframe: 12 months

Overall satisfaction with the procedure via telephone survey (scaled from 0 to 9). Patients answered just one question. Are you satisfied with the procedure? Being 0 = Completely unsatisfied, I regret having undergone a embolization procedure 9=Totally satisfied with the procedure, everything was perfect, I would recommend it to anyone with the same problem.
