RESUMO
Vasectomy has been considered a minor surgical procedure, even more so in view of the fact that, most of the time, it can be performed under local anaesthesia in a doctor's office. However, a particular phenotype is frequently found among those cases in which the urologist decides to use general anaesthesia, that poses a challenge for the surgeon as well as the anaesthetist.
La vasectomia se ha considerado un procedimiento quirúrgico menor, máxime cuando en un alto porcentaje de las veces se puede realizar con anestesia local en un consultorio médico; sin embargo, en aquellos pacientes donde el urólogo decide programar con anestesia general se encuentra frecuentemente un fenotipo particular que ofrece dificultades tanto al cirujano como al anestesiólogo.
