RESUMO

INTRODUCTION: Liver transplant (LT) is today a first choice procedure in a group of hepatic diseases in their acute and chronic terminal stages. It is not, however, a technique that is completely free of complications and those of a neurological nature constitute between 8 47% of those reported. AIMS. The purpose of this study is to present the immediate neurological complications (NC) found in our patients, as well as to determine the predictive factors and their relation to the mortality rate. PATIENTS AND METHODS: From the medical records of 26 patients who received LT at the CIMEQ (July 1999 December 2001), we collected a group of variables related to the donor, the surgical procedure and the post operative period and associated them to the occurrence of NC while these patients were in the ICU. RESULTS: NC were found in 16 patients (61.5%), the most frequent being encephalopathy (30.8%), tremor (26.9%), and convulsions (19.2%). No relation was found between the presence of NC and prior hepatic encephalopathy, the use of a suboptimal donor, nor did it represent a significant increase in the mortality rate. There was a significant relation with LT to recipients rated as grade C on the Child Pugh classification system, the presence of intraoperative hypotension (p= 0.0164) and primary dysfunction of the liver graft (p= 0.041). CONCLUSIONS: NC represented a significant cause of morbidity in the period following a liver transplant in our series, although they had no significant repercussion on the mortality rate. Their presence is related to variables concerning the recipient, the surgical procedure itself and the immediate post operative period.

RESUMO

Se informa que los derivados orthohidroxilados de las aminas aromáticas son metabolitos que se liberan en la vejiga donde originan carcinomas. Se producen en el metabolismo del triptófano cuerpos con estructura similar, entre ellos la 3-hidrociquinurenina y el ácido carcinogenético. Se encuentran estos cuerpos en cantidades excesivas en la orina de los fumadores, quienes son incapaces de transformarlos en nicotenamida. Los fumadores en un grupo de 90 enfermos con carcinoma transicional de vejiga, alcanzaron el 90 porciento, en tanto que en el grupo control, constituido por 90 enfermos con carcinoma del colon, sólo alcanzaron el 40 porciento: 5 porciento>2 (AU)
