Essa complica\u00e7\u00e3o normalmente ocorre meses a anos ap\u00f3s o implante inicial, e dados recentes mostram um tempo mediano at\u00e9 a falha mec\u00e2nica de 41-48 meses, dependendo do fabricante do dispositivo<sup>6<\/sup>. Especificamente entre as falhas mec\u00e2nicas, <strong>os aneurismas de cilindro representam aproximadamente 9,5-11,1% das falhas de dispositivo entre os principais fabricantes<\/strong><sup>6<\/sup>. Para determinados dispositivos infl\u00e1veis de tr\u00eas pe\u00e7as, a taxa de aneurismas ou vazamentos de cilindro foi de 4,7%, com um seguimento mediano de 91 meses<sup>2<\/sup>. Os crit\u00e9rios de sele\u00e7\u00e3o de pacientes para o diagn\u00f3stico incluem homens com pr\u00f3teses penianas infl\u00e1veis que relatam desinsufla\u00e7\u00e3o incompleta, abaulamento vis\u00edvel ou apar\u00eancia assim\u00e9trica do p\u00eanis durante as tentativas de insufla\u00e7\u00e3o<sup>2<\/sup>. Os fatores de risco podem incluir o superdimensionamento dos cilindros e a doen\u00e7a de Peyronie concomitante<sup>2,3<\/sup>. O manejo cir\u00fargico envolve a revis\u00e3o completa do dispositivo, em vez da substitui\u00e7\u00e3o isolada do cilindro, para minimizar o risco de infec\u00e7\u00e3o e evitar a recorr\u00eancia da falha mec\u00e2nica<sup>3,5<\/sup>.
