Biopsia de la almohadilla de grasa de la pared abdominal - Overview

Nombres alternativos

Biopsia de la pared abdominal; Biopsia de la almohadilla de grasa de la pared del abdomen

Definición:

Es la extracción de una pequeña parte de la almohadilla de grasa de la pared abdominal. El procedimiento se realiza con mayor frecuencia con el fin de hacer pruebas para amiloidosis.

Forma en que se realiza el examen:

La aspiración con aguja es el método más comúnmente utilizado para obtener una biopsia de la almohadilla de grasa de la pared abdominal. Se limpia la piel del abdomen y se puede usar un anestésico local para insensibilizar el área. Se introduce una aguja a través de la piel hasta la almohadilla de grasa subcutánea. Se extrae un pequeño núcleo de la capa de grasa con la aguja y se envía al laboratorio para su análisis.

Preparación para el examen:

Generalmente no se requiere de una preparación especial.

Lo que se siente durante el examen:

Aunque el médico pueda haber anestesiado la piel, puede sentirse una leve molestia o presión durante la inserción de la aguja. Posteriormente, el área puede estar sensible o con hematomas por algunos días.

Razones por las que se realiza el examen:

El examen se puede llevar a cabo cuando se sospecha amiloidosis.
