Transcatheter closure of Blalock-Taussig anastomosis with brachial access in a child with obstruction of the left subclavian artery and secondary subclavian steal syndrome

Subclavian Steal in Patients with Blalock-taussig Anastomosis.

ALTHOUGH the collateral anastomotic channels that occur secondary to obstruction of the first segment of the subclavian artery have received relatively little comment by anatomists, the participation by the vertebral artery in such instances has been mentioned.' Recently, the finding of retrograde flow from the vertebral artery on the side of an obstruction in the first part of the subclavian a...

Short Communications Vertebrobasilar Ischemia After Total Repair of Tetralogy of Fallot: Significance of Subclavian Steal Created by Blalock-Taussig Anastomosis Vertebrobasilar Ischemia After Correction of Tetralogy of Fallot

Patients who have undergone a Blalock-Taussig anastomosis for treatment of congenital heart disease may have the vascular anatomy of the subclavian steal syndrome. Cerebral ischemia has been reported in such patients, but not when total surgical correction has eliminated other predisposing factors. We report a patient who developed vertebrobasilar insufficiency 31 years after Blalock-Taussig an...

Transcatheter occlusion of a Blalock-Taussig shunt with a detachable balloon in a child.

A case of transcatheter occlusion of a Blalock-Taussig shunt with a detachable silicone filled balloon is described. This 11 year old boy had previously had a repair of tetralogy of Fallot together with ligation of a large Blalock-Taussig shunt. Though there was a good surgical result, the shunt proved to be incompletely closed leaving a significant left to right shunt. As an alternative to a f...

Transcatheter closure of antegrade pulmonary blood flow with Amplatzer septal occluder after Fontan operation

Transcatheter Closure Modification of the Fontan Operation for Patients at Increased Risk

Ventricular dysfunction, elevated pulmonary vascular resistance, and residual distal pulmonary artery distortion contribute to early mortality after a Fontan operation; they may be transient or reversible. A baffle fenestration, allowing right-to-left shunting, maintains cardiac output and limits right atrial pressure. A baffle fenestration was surgically created at the time of a modified Fonta...
