Contribution to the study of angiographic semiology of the thyroid
Contribución al estudio de la semiología angiográfica del tiroides
Resumen:
We have 40 observations made through infraclavicular puncture of the subclavian artery and through a Seldinger catheter and selective technique which is a contributionof angiographic semiology to the study of the thyroid gland. It is accompanied by a general analysis of the vascular trunks, thyroid pedicles and intraparenchimatose circulation.Character·stic aspects of difuse goiter are established: an image of well defined uniform opacity, with intense capture of the contrast by the arteriolo-capillarybed.Nodular goiter, shows a complex radiological morphology: its most frequent signs are irregular impregnation images and vascular tracings which outline displacementstructures. Thyroid atrophy in mixedema is expressed by the small calibre of its pedicles and limited thyroid vascularization. The author concludes that angiographysupplies important data on various aspects: diagnosis of the anatomo-clinical variety of goiter; morphological elements of interest in the planning of surgery; functionalelements deduced by the angiographic profile of the gland; elements which appear in the ,comparison of the angiogram with other exploratory means: gammagram,histopathology, etc.; exploration of the residual stump and postoperatory recurrency.
Se estudian 40 observaciones realizadas por punción infraclavicular de la arteria subclavia y mediante catéter Seldinger y técnica selectiva como aporte a la semiologíaangiográfica de la glándula tiroides. Se hace el análisis genérico de troncos vascularet pedículos tiroideos, circulación intraglandular. Se establecen aspectos característicos delbocio difuso: imagen de opacidad uniforme y bien limitada, con intensa .captación del contraste por el lecho arteriocapilar. El bocio nodular muestra morfología radiológicacompleja: los signos más frecuentes son las imágenes de impregnación irregular y trazos vasculares que dibujan estructuras de desplazamiento. La atrofia tiroidea en el mixedema, se expresa por el escaso calibre de sus pedículos y escasa vascularización tiroidea. Se concluye que la angiografía aporta hechos de interés real en varios aspectos:diagnóstico de la variedad anatomoclínica del bocio; elementos morfológicos de interés en la planificación del acto operatorio; elementos de orden funcional deducidosdel perfil angiográfico de la glándula; elementos que surgen de la confrontación .el angiograma con otros medios de exploración: gammagrama, histopatología, etc.;exploración del muúón residual y de las recidivas postoperatorias.
