septectomy การใช้

Stage 1 of the Norwood procedure involves atrial septectomy and transection and ligation of the distal main pulmonary artery.
In 1950, American surgeons Alfred Blalock and C . Rollins Hanlon introduced the " Blalock-Hanlon atrial septectomy ", which was then routinely used to palliate patients.
In 1966, American surgeons William Rashkind and William Miller transformed the palliation of d-TGA patients with the innovative " Rashkind balloon atrial septostomy ", which, unlike the thoracotomy required by a septectomy, is performed through the minimally invasive surgical technique of cardiac catheterization.
An atrial septectomy is the surgical removal of the atrial septum; this is performed when a patent foramen ovale ( PFO ), or atrial septal defect ( ASD ) are not present and additional shunting is required to raise the oxygen saturation of the blood flowing eventually into the aorta.
The HLM is turned off and the aortic and atrial cannula are removed, then an incision is made in the right atrium, through which the congenital or palliative atrial septal defect ( "'ASD "') is repaired; where a Rashkind balloon atrial septostomy was used, the ASD should be able to be closed with sutures, but cases involving large congenital ASDs or Blalock-Hanlon atrial septectomy, a pericardial, xenograft, or Dacron patch may be necessary.
