RESUMO
Ascites is the fluid accumulation in the peritoneal cavity, and it is the consequence of a wide variety of entities, being liver cirrhosis the most common one. In this kind of patients, the development of ascites results from splanchnic vasodilation; decreased effective circulating volume; the activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system; and a systemic inflammatory process. Its management is diverse and depends on the severity of the hemodynamic disturbance and other clinical manifestations. In recent years, therapeutic strategies have been developed, but they tend to result unconventional, so new evidence demonstrates the advantages of non-selective beta-blockers for the survival rate of patients with end-stage cirrhosis and ascites.

INTRODUCTION AND OBJECTIVES: The association between non-alcoholic fatty liver disease and cerebral hemodynamics arises from cardiovascular damage mechanisms such as endothelial dysfunction, arterial wall increased stiffness, high thickness of the intimate index of the internal carotid artery, left ventricular hypertrophy, left diastolic dysfunction, calcification coronary arteries and increased epicardial fat. The multidirectional relationship between systemic inflammation and lipid metabolism constitutes a common and simultaneous mechanism that causes vascular damage. This study aims to provide insight into the relationship between non-alcoholic fatty liver disease and the function of systemic circulation and cerebral circulation using Doppler ultrasound. PATIENTS AND METHODS: Is an observational, cross-sectional, prospective, comparative study conducted at Medica Sur Hospital. Thirty-five patients were selected consecutively. The patients consulted neurological service for various symptoms without severity criteria, such as vertigo, primary headache and balance disturbances. RESULTS: There is a difference in the variables mean of the right MCA PI (pâ¯=â¯0.023), left MCA PI" (pâ¯=â¯0.004), and left VA PI (pâ¯=â¯0.036) between the control and NAFLD groups. The correlation analysis between these variables and the CAP showed a positive correlation of the three variables with the CAP, "right MCA PI" (râ¯=â¯0.384), left MCA PI "(râ¯=â¯0.509) and" left VA PI " (râ¯=â¯0.551). CONCLUSIONS: This study demonstrates a subclinical process of the middle cerebral artery in subjects with NAFLD, which suggests it may be involved in the disease development and points the need to make decisions for this liver manifestation prevention and treatment.
