Enfermedades vasculares del hígado. Guías Clínicas de la Sociedad Catalana de Digestología y de la Asociación Española para el Estudio del Hígado / Vascular diseases of the liver. Clinical Guidelines from the Catalan Society of Digestology and the Spanish Association for the Study of the Liver

Las enfermedades vasculares hepáticas, a pesar de su relativamente baja prevalencia, representan un problema de salud importante en el campo de las enfermedades hepáticas. Una característica común a muchas de estas enfermedades es que pueden causar hipertensión portal, con la elevada morbimortalidad que ello conlleva. Con frecuencia estas enfermedades se diagnostican en pacientes jóvenes y el retraso en su diagnóstico y/o un tratamiento inadecuado pueden reducir de forma importante la esperanza de vida. El presente artículo revisa la evidencia actual en el síndrome de Budd-Chiari, la trombosis venosa portal en pacientes no cirróticos, la hipertensión portal idiopática, el síndrome de obstrucción sinusoidal, las malformaciones vasculares hepáticas en la telangiectasia hemorrágica hereditaria, la trombosis portal en la cirrosis, otras patologías vasculares menos frecuentes como las fístulas arterioportales, así como un apartado sobre el diagnóstico por imagen de las enfermedades vasculares hepáticas y su tratamiento desde el punto de vista hematológico (estudio de la diátesis trombótica y tratamiento anticoagulante). Las recomendaciones se han realizado de acuerdo a los estudios publicados extraídos de Pubmed. La calidad de la evidencia y la intensidad de las recomendaciones fueron graduadas de acuerdo al sistema Grading of Recommendations Assessment Development and Evaluation (GRADE). Cuando no existían evidencias suficientes, las recomendaciones se basaron en la opinión del comité que redactó la guía.

Despite their relatively low prevalence, vascular diseases of the liver represent a significant health problem in the field of liver disease. A common characteristic shared by many such diseases is their propensity to cause portal hypertension together with increased morbidity and mortality. These diseases are often diagnosed in young patients and their delayed diagnosis and/or inappropriate treatment can greatly reduce life expectancy. This article reviews the current body of evidence concerning Budd-Chiari syndrome, non-cirrhotic portal vein thrombosis, idiopathic portal hypertension, sinusoidal obstruction syndrome, hepatic vascular malformations in hereditary haemorrhagic telangiectasia, cirrhotic portal vein thrombosis and other rarer vascular diseases including arterioportal fistulas. It also includes a section on the diagnostic imaging of vascular diseases of the liver and their treatment from a haematological standpoint (study of thrombotic diathesis and anticoagulation therapy). All recommendations are based on published studies extracted from PubMed. The quality of evidence and strength of recommendations were rated in accordance with the GRADE system (Grading of Recommendations, Assessment Development and Evaluation). In the absence of sufficient evidence, recommendations were based on the opinion of the committee that produced the guide.

Combined liver-kidney transplantation in patients with cirrhosis and chronic kidney disease.

The outcome of patients with cirrhosis and chronic kidney disease treated with combined liver-kidney transplantation (CLKT) is not well known because most series of patients treated with CLKT include not only patients with cirrhosis but also patients with inherited diseases without cirrhosis. To evaluate to what extent the combined kidney transplantation impairs posttransplantation outcome compared to liver transplantation (LT) alone, the outcome of patients with cirrhosis and chronic kidney disease treated with CLKT (n = 20) was compared to that of a group of patients with cirrhosis without chronic kidney disease treated with LT alone matched by age, sex, year of transplantation and severity of cirrhosis (n = 60). The primary end point of the study was survival, and secondary end points were outcome of renal function and complications within 6 months of transplantation. Patients with CLKT had a higher incidence of bacterial infections and transfusion requirements compared to LT patients. The incidence of acute renal failure during the first 6 months was similar, yet the severity of renal failure was greater in patients with CLKT. Hospital and intensive care unit (ICU) stays were longer in the CLKT group. One- and three-year survival probabilities in patients treated with CLKT were 80 and 75% compared to 97 and 88%, respectively, in patients treated with LT. In conclusion, CLKT for patients with cirrhosis and chronic kidney disease is associated with a relatively high frequency of postoperative complications that moderately impairs short-term survival. However, 3-year survival of patients with cirrhosis treated with CLKT is excellent.
