Dans le cas d\u2019une suspicion de maladie art\u00e9rielle ou veineuse, un \u00e9chodoppler peut \u00eatre prescrit par votre m\u00e9decin.

Qu\u2019est-ce qu\u2019un \u00e9chodoppler ?<\/strong>
<\/p><\/div><\/div>\n\n\n\n


L\u2019\u00e9chographie doppler est un examen tr\u00e8s pr\u00e9cis qui permet d\u2019\u00e9tudier \u00e0 la fois l\u2019anatomie et des l\u00e9sions sur les parois vasculaires<\/strong>, c\u2019est \u00e0 dire des art\u00e8res<\/strong> et veines<\/strong> (plaques, plus ou moins calcifi\u00e9es, dissections, h\u00e9matomes, an\u00e9vrysmes, r\u00e9tr\u00e9cissements, variantes anatomiques), ainsi que le flux du sang <\/strong>(modifications h\u00e9modynamiques, vitesses, d\u00e9bit, turbulences, sens). Ceci, dans le but de d\u00e9tecter une potentielle anomalie comme une art\u00e9riopathie ou \u201cart\u00e9rite\u201d (art\u00e8re bouch\u00e9e ou r\u00e9tr\u00e9cie), une insuffisance veineuse ou une phl\u00e9bite (thrombose veineuse, c’est-\u00e0-dire veine bouch\u00e9e par un caillot). 

L\u2019\u00e9chodoppler est un examen indolore, non invasif et sans danger pour la sant\u00e9.

Pourquoi faire un \u00e9chodoppler ?<\/strong>
<\/p><\/div><\/div>\n\n\n\n


Un examen par \u00e9cho-doppler est g\u00e9n\u00e9ralement effectu\u00e9 pour les cas suivants :

<\/p><\/div><\/div>\n\n\n\n

– D\u00e9tecter une \u201cart\u00e9riopathie\u201d  : art\u00e8res encrass\u00e9es par des d\u00e9p\u00f4ts qui peuvent parfois r\u00e9tr\u00e9cir le vaisseau ou le boucher, on parle alors de st\u00e9nose ou d\u2019occlusion art\u00e9rielle. Certaines situations sont plus \u00e0 risque de fabriquer ces d\u00e9p\u00f4ts sur les parois art\u00e9rielles : diab\u00e8te, hypertension art\u00e9rielle, tabagisme, dyslipid\u00e9mie (\u201ccholest\u00e9rol\u201d), surpoids, mais aussi l\u2019h\u00e9r\u00e9dit\u00e9 (avoir une personne de sa famille qui a ce type de probl\u00e8me jeune).

L\u2019int\u00e9r\u00eat de d\u00e9pister cette pathologie est de la traiter avant que des complications potentiellement graves ne surviennent :

– infarctus, AVC, art\u00e9riopathie symptomatique (douleur des jambes \u00e0 la marche voire au repos).

– d\u00e9pister un an\u00e9vrisme de l\u2019aorte dans le cas d\u2019ant\u00e9c\u00e9dents familiaux.

– d\u00e9tecter une thrombose veineuse profonde ou phl\u00e9bite (veine bouch\u00e9e par un caillot), dont le risque si non trait\u00e9e est l\u2019embolie pulmonaire.

– d\u00e9tecter une insuffisance veineuse (des varices).

– rechercher la cause d\u2019\u0153d\u00e8mes des membres inf\u00e9rieurs (jambes ou chevilles gonfl\u00e9es) ou sup\u00e9rieurs

– plaies ou ulc\u00e8res des orteils ou des jambes.

– troubles vasomoteurs (extr\u00e9mit\u00e9s froides ou chaudes, changements de couleurs)

– En pr\u00e9vision d\u2019une intervention chirurgicale ou endovasculaire sur une art\u00e8re ou veine 

– contr\u00f4le suite \u00e0 une intervention chirurgicale ou endovasculaire.

D\u00e9roulement de l’examen :<\/strong>
<\/p><\/div><\/div>\n\n\n\n


Vous \u00eates allong\u00e9(e) sur le dos. 

Un gel est appliqu\u00e9 sur la zone \u00e0 examiner (membres inf\u00e9rieurs ou sup\u00e9rieurs), puis le m\u00e9decin d\u00e9place la sonde le long de la veine ou de l\u2019art\u00e8re cibl\u00e9e \u00e0 travers la peau et r\u00e9alise de nombreuses mesures \u00e0 la fois morphologiques (\u00e9paisseur de plaques,  r\u00e9tr\u00e9cissement de vaisseaux en diam\u00e8tre \u2026) et h\u00e9modynamiques (caract\u00e9ristiques de la circulation, vitesses, d\u00e9bit, amortissement des flux \u2026). 

Dans le cas d\u2019un bilan d\u2019insuffisance veineuse (recherche de \u201cvarices\u201d), le m\u00e9decin vous demandera en fin d\u2019examen de rester debout quelques minutes sur un escabeau de phl\u00e9bologie (haut de 2 marches) pour tester votre r\u00e9seau veineux de fa\u00e7on optimale.

Dans certains cas (recherche de d\u00e9fil\u00e9 thoraco-brachial ou d\u2019art\u00e8re poplit\u00e9e pi\u00e9g\u00e9e), le m\u00e9decin vous demandera de r\u00e9aliser des mouvements en cours d\u2019examen, on parle de man\u0153uvres dynamiques.

Les images g\u00e9n\u00e9r\u00e9es sont analys\u00e9es, un compte-rendu oral est ensuite r\u00e9alis\u00e9 par le Dr. Laporte-Gladu pour vous donner ses conclusions et r\u00e9pondre \u00e0 vos questions. 

Enfin, vos clich\u00e9s d\u2019examen vous sont remis via l’application Medifile<\/em>. Ces r\u00e9sultats sont \u00e9galement adress\u00e9s au m\u00e9decin prescripteur ou \u00e0 votre m\u00e9decin traitant.
<\/p><\/div><\/div>\n\n\n\n


Dur\u00e9e de l\u2019examen : entre 20 et 40 minutes selon la zone \u00e9tudi\u00e9e.<\/strong>
