Fístula arteriovenosa pulmonar - Overview

Nombres alternativos

Malformación arteriovenosa pulmonar

Definición:

Es una afección en la cual se desarrolla una conexión (fístula) anormal entre una arteria y una vena en los pulmones. Como resultado, la sangre pasa a través de los pulmones sin recibir suficiente oxígeno.

Causas, incidencia y factores de riesgo:

Las fístulas arteriovenosas pulmonares generalmente son el resultado de una enfermedad genética (heredada) que causa el desarrollo anormal de los vasos sanguíneos del pulmón. Las fístulas también pueden ser una complicación de una enfermedad hepática.

Los pacientes que padecen la enfermedad de Rendu-Osler-Weber (ROWD, por sus siglas en inglés), también llamada telangiectasia hemorrágica hereditaria (THH), con frecuencia tienen vasos sanguíneos anormales en muchas partes del cuerpo.
