Comparar el número de vasos identificados y las velocidades e índices de pulsatilidad de los mismos mediante doppler transcraneal (DTC) y dúplex transcraneal codificado en color (DTCC) en una población de enfermos con traumatismo craneoencefálico (TCE).
Material y métodosSe estudiaron 30 enfermos ingresados por TCE en una Unidad de Cuidados Intensivos (UCI) neurocríticos. Consecutivamente se realizaron estudios mediante DTC y DTCC. Se compararon la tasa de insonación de las arterias del polígono de Willis y los parámetros hemodinámicos obtenidos.
ResultadosLa edad media fue de 50 años. El 67% fueron varones. En el estudio mediante DTCC se insonó la arteria carótida interna en un 95% de los casos, la arteria cerebral media (ACM) en el 95% de las ocasiones, la arteria cerebral anterior (ACA) en un 91% y la arteria cerebral posterior (ACP) en un 92% de los estudios. Mediante DTC convencional se hallaron en un 29%, 93%, 67% y 35% respectivamente. La velocidad media mediante DTCC y DTC en la ACM fue de 79cm/ seg vs 59cm/seg respectivamente (p<0.0001), en la ACA de 61cm/seg vs 42cm/seg (p<0.0001) y en la ACP de 43cm/seg y 33cm/seg (p<0.0001).
ConclusionesEl DTCC permite un estudio hemodinámico más completo en los enfermos con TCE ingresados en la UCI. Su impacto en el pronóstico del TCE deberá determinarse en próximos estudios.
To compare the number of vessels identified and mean velocity and pulsatility index values obtained by transcranial doppler (TCD) and transcranial color coded sonography (TCCS) in patients with traumatic brain injury (TBI).
MethodsThirty patients suffering from TBI admitted in our neurocritical Intensive Care Unit (ICU) were studied. We performed consecutive studies by TCD and TCCS. The number of Circle of Willis vessels insonated and the hemodynamic parameters were compared.
ResultsMean age was 50 years. Twenty patients were male. By using TCCS, internal carotid artery was insonated in 95%, middle cerebral artery (MCA) in 95%, anterior cerebral artery (ACA) in 91% and posterior cerebral artery (PCA) in 92% of the studies. Using conventional TCD they were insonated in 29%, 93% 67% and 35% of the studies respectively. Mean velocity values measured by CCS and TCD in MCA were 79cm/sec vs 59cm/sec respectively (p<0.0001), in ACA were 61cm/sec vs 42cm/sec (p<0.0001) and in PCA were 43cm/sec vs 33cm/sec (p<0.0001).
ConclusionTCCS allows a high quality hemodynamic study of TBI patients admitted to the ICU. Further studies must define its impact on outcome of TBI patients.
