Contrast Enhanced Echocardiography for Detection of Intrapulmonary Shunts in Liver Transplant Candidates
Background: Intrapulmonary vascular abnormalities associated with liver cirrhosis may result in intrapulmonary right-to-left shunt and hypoxemia. The aim of this study was to use contrast enhanced echocardiography to detect intrapulmonary vascular abnormalities in patients with liver cirrhosis candidates for liver transplantation. Methods: One hundred and two adult patients underwent contrast e...
متن کاملAnatomical and functional intrapulmonary shunt in acute respiratory distress syndrome.
OBJECTIVES The lung-protective strategy employs positive end-expiratory pressure to keep open otherwise collapsed lung regions (anatomical recruitment). Improvement in venous admixture with positive end-expiratory pressure indicates functional recruitment to better gas exchange, which is not necessarily related to anatomical recruitment, because of possible global/regional perfusion modificatio...
متن کاملArterial hypoxaemia in cirrhosis: fact or fiction?
BACKGROUND Although low arterial oxygen tension (Po2) has been claimed to occur in one to two thirds of patients with cirrhosis, hypoxaemia appears to be rare in clinical practice. AIMS To assess the frequency of arterial hypoxaemia in cirrhosis in relation to clinical and haemodynamic characteristics. PATIENTS One hundred and forty two patients with cirrhosis without significant hepatic en...
متن کاملIntrapulmonary agenesis of venous system and bronchopulmonary arterial anastomosis.
Agenesis of the intrapulmonary and extrapulmonary veins of the right lung was found by angiography and histological examination in a three year old boy. Blood supplied by the intersegmental arteries drained via the pulmonary arteries of the right lung into main and left pulmonary arteries. This caused a shunt between the aorta and pulmonary artery. Agenesis of the pulmonary venous system as a c...
متن کاملArterial hypoxaemia following premedication in patients with coronary artery disease.
The effect of premedication with morphine and scopolamine, morphine alone, and scopolamine alone on arterial oxygen tension has been studied in patients with coronary artery disease undergoing bypass operations. Control arterial blood samples were obtained with the patients in the supine position breathing room air the day before operation. A second arterial blood sample was taken in the induct...
