Persistencia y repermeabilización del conducto de Cuvier izquierdo / Persistence and restoration of the patency of the left duct of Cuvier

La hepatopatía crónica favorece la redistribución del flujo hacia la circulación sistémica. Si bien es poco frecuente, la repermeabilización de los conductos venosos embrionarios causa el aumento de la presión en la circulación portal. Nuestro objetivo es dar a conocer la persistencia y permeabilidad del conducto venoso de Cuvier izquierdo y su presentación en imágenes

The increased pressure in the portal circulation due to a chronic liver disease favours the redistribution of the flow to the systemic circulation. Although rare, reperfusion of embryonic venous channels may be a possibility. The aim of this article is to determine the persistence and the patency of the ductus venosus, called the left duct of Cuvier, and its presentation in images

Massive ocular hemorrhage resulting in blindness in a patient with the sickle cell trait who developed leptospirosis. Case report

This case report describes the findings of a 18 year-old black male from Bahia, a Northeastern state in Brazil, with the sickle cell trait, who developed bilateral hyphema and vitreous hemorrhage with blindness in the course of leptospirosis. The patient started to complain of blurred vision four days after the start of fever and muscular pain and approximately twelve hours after the introduction of penicillin. The severity of the leptospirosis in conjunction with sickle cell trait was considered to be the most likely explanation for this ocular complication
