[The use of pulsed echo-Doppler in verifying the patency of by-passes and reconstructions of the humeral artery]. / Utilización de EcoDoppler pulsado en la comprobación de la permeabilidad de by-passes y reconstrucciones de la arteria humeral.

Personal experiences using Duplex as alternative method to the invasive techniques in 17 patients after the surgical restoration of their injured humeral arteries, are presented. Duplex was used during the control and also during the follow-up of the surgical procedures.

[Importance of morphologic evaluation of carotid lesions in their correlation with cerebral ischemic pathology]. / Importancia de la valoración morfológica de las lesiones carotídeas en su correlación con patología isquémica cerebral.

Authors present a review of 182 atheromatous plaques into the extracranial carotid trunks. Diagnosis of such pathologies were made by Eco-Doppler on 615 patients. Objective was to determinate the emboligen potential of the plaques following structural and functional criteria. Almost all the symptomatic plaques with functional disturbances showed some structural injury with emboligen potential. Two third parts of all the symptomatic diseases hemodynamically no-significant were associated with plaques with emboligen power. On stenosis higher than 70%, functional criterium was more important for study than structural criterium.
