Avaliação intra-operatória da pressão portal e resultados imediatos do tratamento cirúrgico da hipertensão portal em pacientes esquistossomóticos submetidos a desconexão ázigo-portal e esplenectomia

Abstract

These results have demonstrated that the esophagogastric devascularization with splenectomy promotes immediate decrease in the portal pressure and a consequent reduction in the esophageal varices size. We also observed that the risk of mortality and severe complications related to this technique is not insignificant.

Doppler Ultrasound Could Predict Varices Progression and Rebleeding After Portal Hypertension Surgery: Lessons from 146 EGDS and 10 Years of Follow‐Up

“…EGDS reduces portal vein diameter and portal flow velocity leading to a decrease in the vein’s hyper flux component. This in turn reduces both diameter and number of esophagogastric varices [5, 10, 51–57]. Our study showed portal diameter decrease during the postoperative period, mirroring results of other studies.…”

Does the Drop in Portal Pressure After Esophagogastric Devascularization and Splenectomy Influence the Variation of Variceal Calibers and the Rebleeding Rates in Schistosomiasis in Late Follow-Up?

“…Patients were divided into two groups, according to the portal pressure drop, in more or less than 30%.The threshold value of 30% was chosen because it was the average indicated by studies that measured the portal pressure before and after EGDS or splenectomy 4 , 7 , 11 , 22 .…”
