Correlación entre el diámetro de la vena porta, recuento plaquetario y tiempo de protrombina en el diagnóstico de várices esofágicas en pacientes con enfermedad hepática crónica del Hospital de Lídice durante el período Enero 2002- Marzo 2007.

Recent studies have reported non invasive diagnostic alternatives for Esophageal Varices (EV), identifying prognostic factors such as: low platelet count, enlarged spleen, augmented portal vein diameter, diminished prothrombin activity level (PT), and an advanced Child-Pugh classification. Objectives: to determine the relationship between portal vein diameter, platelet count and PT as negative predictors for the presence of EV. Methods: A retrospective study was carried out among patients with chronic hepatic disease and endoscopic diagnosis of EV, correlating portal vein diameter, platelet count and PT, at the Gastroenterology Service, Hospital of Lídice; between January 2002 and March 2007. Results: The diameter of the portal vein ranged from 8, 00 to 20, 00 mm; the platelet count between 44,000 and 650,000 mm and the difference between the PT varied from 0, 00 secs and 12, 30 secs. The most frequent endoscopic diagnosis of EV was grade II (58%), related with a mean portal vein diameter of 12, 21 mm, platelet count of 151,18mm and PT of 1, 36 secs. Discussion: we found a direct proportional relationship between portal vein diameter and the grade of EV, and an inversely proportional relationship with platelet count and PT.
