Nombres alternativos

Biopsia del túnel del carpo

Definición:

Es un examen en el cual se extrae una pequeña parte de tejido del túnel carpiano (parte de la muñeca).

Forma en que se realiza el examen:

Se limpia la piel de la muñeca y se inyecta un medicamento para insensibilizar el área. A través de una pequeña incisión en la piel, se toma una muestra del tejido del túnel carpiano, lo cual se hace por medio de la extirpación directa del tejido o por aspiración con aguja.

Algunas veces, este procedimiento se realiza al momento de hacer una cirugía de liberación del túnel carpiano.

Preparación para el examen:

El médico puede solicitarle que no coma nada durante unas cuantas horas antes del examen.

Lo que se siente durante el examen:

Es probable que usted experimente una sensación de ardor o quemazón cuando se inyecta el anestésico. Usted puede igualmente sentir algo de presión o sensación de tirón durante el procedimiento. Posteriormente, el área puede estar sensible o adolorida por algunos días.

Razones por las que se realiza el examen:

El examen generalmente se hace para descartar una afección llamada amiloidosis.
