Resumen

El objeto de este trabajo ha sido la evaluación de la potencial capacidad de los estudios Doppler color modo «energía» (power) con contraste intravenoso en el diagnóstico de la colecistitis aguda.

Hemos examinado 18 casos de colecistitis aguda y 5 de colecistitis crónica así como a un grupo control de 11 pacientes sin enfermedad vesicular. En estos pacientes se valoró la vascularización de las paredes vesiculares mediante ecografía Doppler color modo power antes y después de la administración intravenosa de contraste (Levograf®). La vascularización se evaluó mediante una escala en tres niveles (grados 0, 1 y 2) en función de la intensidad y de la localización de las señales de color.

El examen basal con Doppler power puso de manifiesto una sensibilidad en el diagnóstico de colecistitis aguda del 38,8%. Tras administración de contraste IV, la sensibilidad fue del 100%.

En conclusión, el uso de contrastes ecográficos permitió el diagnóstico de colecistitis aguda con sensibilidad y especificidad del 100% y resultó una buena alternativa diagnóstica a otros estudios complementarios o de imagen.

The aim of this study was to evaluate the potential capacity of color and power Doppler sonography with intravenous contrast medium in the diagnosis of acute cholecystitis. We examined 18 patients with acute cholecystitis, 5 patients with chronic cholecystitis and a control group of 11 patients without gallbladder disease.

In these patients, vascularization of the gallbladder wall was evaluated by color and power Doppler sonography before and after intravenous administration of contrast medium (Levograf®). Vascularization was evaluated with a 3-point scale (grades 0, 1 and 3) according to the intensity and localization of signs of color. In the diagnosis of acute cholecystitis, basal examination with power Doppler had a sensitivity of 38.8%. After administration of intravenous contrast medium, sensitivity was 100%. In conclusion, the use of sonographic contrast media in the diagnosis of acute cholecystitis showed a sensitivity and specificity of 100%. This technique represents a viable diagnostic alternative to other complementary or imaging studies.
