The aim of this study is to analyze the incidence, risk factors, management, and follow-up of patients with portal vein thrombosis (PVT) undergoing primary orthotopic liver transplantation (OLT). Four hundred fifteen OLTs were performed in 391 patients. In 62 patients, partial (group 1; n ‫؍‬ 48) or complete (group 2; n ‫؍‬ 14) PVT was found at the time of surgery. Portal flow was reestablished by venous thrombectomy. In this study, we compare 62 primary OLTs performed in patients with PVT at the time of OLT with a group of 329 primary OLTs performed in patients without PVT (group 3) and analyze the incidence of PVT, use of diagnostic methods, surgical management, and outcome. We found no significant differences among the 3 groups for length of surgery, cold and warm ischemic times, and postoperative stay in the intensive care unit. With the piggyback technique, groups 1 and 2 had greater blood losses and required more blood transfusions than group 3. The early reoperation rate was greater in group 2. The incidence of rethrombosis was 4.8% (group 1, 2%; group 2, 14.3%). Reexploration and thrombectomy (2 patients) and retransplantation (1 patient) had a 100% mortality rate. In particular, the mortality rate of patients with complete PVT with extension into the splanchnic veins is high (33%). Three-month and 4-year patient survival rates were statistically similar in the 3 groups. The presence of PVT at the time of OLT is not a contraindication for OLT. However, if PVT extends into the splanchnic veins, the outcome is guarded. (Liver Transpl 2001;7:125-131.)

Ésta sostiene que mentir es cognitivamente más complejo que decir la verdad y que un aumento artificial de la dificultad cognitiva durante una entrevista hará que el mentiroso muestre señales delatoras de sobrecarga cognitiva. En este trabajo argumentamos que mentir no es siempre más complejo que decir la verdad. Inferir automáticamente engaño a partir de indicadores de carga cognitiva puede llevar a error. Los profesionales deben conocer el funcionamiento de la memoria y del sistema cognitivo para poder comprender el significado de los indicadores de carga cognitiva y los científicos deben desarrollar modelos cognitivos de la mentira y elaborar sus hipótesis a partir de mecanismos y procesos cognitivos específicos. Por último, puesto que las emociones influyen en la cognición, no puede obviarse su papel en la detección de mentiras. a b s t r a c tRecently, the dearth of evidence supporting nonverbal-emotional approach to lie detection has favored the development of cognitive orientation. According to cognitive orientation, lying is cognitively more complex than truth telling, such that an artificial increase of cognitive difficulty during an interview will lead liars to show indicators of cognitive overload. In this paper we argue that lying is not always more cognitively difficult than telling the truth. Automatically inferring deception from the observation of cognitive load indicators may lead to erroneous judgments. Practitioners must know how memory and the human cognitive system work, so they can understand the actual meaning of cognitive load indicators. Scientists should develop cognitive models of deception to guide their research, and should base their research hypotheses on specific cognitive mechanisms and processes. Finally, because emotions influence cognition, the role of emotions in lie detection cannot be neglected. © 2017 Colegio Oficial de Psicólogos de Madrid. Published by Elsevier España, S.L.U.
