15 صفحه اولRegional pulmonary blood flow in patients with circulatory shunts.
Carbon dioxide labelled with oxygen-15 can be used to compare the blood flow in different regions of the lung. Results obtained with this technique in normal subjects at rest with the chest upright show that there is a much higher perfusion per unit of alveolar volume in the lower zone than in the upper zone. On moderate exercise the flow increases in both zones but the lower zone blood flow re...
متن کاملDuctal stenting for acute thrombosis of modified Blalock-Taussig shunts.
transannular patch was placed and stent flow was interrupted with a clip. A 1500-g neonate diagnosed with pulmonary atresia with ventricular septal defect, right aortic arch, ductus left and left superior vena cava, was administered prostaglandin to 2 months and underwent a right MBT shunt. Prostaglandin perfusion was restarted at 24 h as saturation was <65%. Echocardiography detected no flow i...
متن کاملBidirectional cavopulmonary shunt with additional pulmonary blood flow.
There are some controversies regarding the usefulness of leaving additional pulmonary blood flow when establishing a bidirectional cavopulmonary shunt. From April 2002 to September 2008, 13 patients (mean age, 24 +/- 16 months) underwent a bidirectional cavopulmonary shunt procedure with fine adjustment of additional pulmonary blood flow, as an intermediate step before the Fontan operation. The...
متن کاملPulmonary blood flow after total cavopulmonary shunt.
The pattern of pulmonary blood flow was studied in three patients after a total cavopulmonary shunt procedure. Doppler studies showed a phasic pattern of flow which varied with the respiratory cycle. Pulmonary blood flow was increased with normal inspiration, and was much augmented by the Mueller manoeuvre. This suggests that flow was occurring when a negative intrathoracic pressure was generat...
