1/4. Direct identification of patency achieved by a bi-directional Glenn shunt procedure: images by volume rendering using electron-beam computed tomography.The present study aimed to identify the patency achieved by a bi-directional Glenn shunt procedure by shaded volume rendering (VR) images using electron-beam computed tomography (EBCT). A Damus Kay-Stanzel type procedure was performed on a female with hypoplastic left heart syndrome who later received a bi-directional Glenn shunt to increase pulmonary blood flow. In considering the characteristics of the bi-directional Glenn shunt procedure, in which the superior vena cava is connected to the right pulmonary artery, an early phase acquisition protocol with injection of contrast material from the right cubital vein using the step volume scan mode of EBCT was planned to acquire blood flow information. Excellent spatial resolution volume data of the heart and great vessels was obtained from which 3-dimensional images were made. Bi-directional Glenn shunt flow could be observed directly and the complex morphology and relationships between adjacent structures were revealed by 3-dimensional VR imaging. The combination of EBCT and VR can provide useful information to evaluate congenital heart diseases.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/4. Mechanical thrombectomy using the AngioJect in a child with congenital heart disease.Acute thrombosis of a vascular channel can be a serious and perhaps fatal complication. We describe a patient who developed complete thrombosis of the left pulmonary artery following catheter placement of a stent in this vessel shortly after open heart surgery. The thrombosis was successfully removed using the Possis AngioJet mechanical thrombectomy catheter.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/4. Portosystemic shunt with polysplenia and hypoplastic left heart syndrome.We report a unique case of portosystemic shunt with polysplenia and hypoplastic left heart syndrome. The abnormal vessel connected the right renal vein and the splenic vein. The shunt flow was from the systemic vein to the portal vein before the Fontan-type operation, but it reversed and ran from portal vein to systemic vein after the Fontan-type operation.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/4. hypoplastic left heart syndrome with intact atrial septum--attempt of an interventional palliation by ductal and interatrial stent implantation.In patients with hypoplastic left heart syndrome (HLHS) and intact atrial septum, the blood entering the left atrium cannot egress. emergency treatment interventionally or surgically is mandatory immediately after birth. We describe a patient with HLHS and intact atrial septum who underwent successful transvenous atrial septostomy immediately after birth. When the interatrial communication became restrictive, stent implantation into the arterial duct and into the atrial septum was performed on the 7th day of life. Despite good hemodymanic response, the lung damage was severe and persistent, rendering staged surgical correction impossible. The child died on the 23rd day of life. autopsy showed patent and correct placed stents in the duct and the atrial septum. There was severe dilatation of pulmonary lymphatic and venous vessels, suggestive of long-standing pulmonary venous hypertension. In conclusion, this form of HLHS has a poor prognosis despite early and aggressive interventional treatment.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
