Usefulness of the Vein Cuff Technique for Recurrent Stenosis due to Intimal Hyperplasia in Prosthetic Graft and Autologous Vein Graft Anastomosis / 日本心臓血管外科学会雑誌

We sometimes encounter the case that we have to make an anastomosis between a prosthetic graft and an autologous vein graft in revascularization of a lower extremity. However, it is said that the intimal hyperplasia in the anastomosis site of a prosthetic graft and autologous vein graft has a tendency to become severe in the long term postoperatively. We herein report a case in which a vein cuff (St. Mary's boot) technique was very useful to prevent recurrent stenosis due to intimal hyperplasia. No recurrence of stenosis in repair lesion has been detected for 7.5 years after operation.

A Case of Residual Atrial Septal Defect with Left Atrial Isomerism Requiring Reoperation 37 Years after the First Operation / 日本心臓血管外科学会雑誌

A 47-year-old female was admitted to our hospital for management of dyspnea. She had undergone surgery for an atrial septal defect (ASD) at the age of 17. Computed tomography revealed left isomerism, inferior vena cava interruption with azygos continuation and a residual ASD. Intra-operative findings showed that the residual ASD was positioned across the orifice of the hepatic vein. The previous suture line could be identified in the partially-closed atrial septum above the residual defect. Re-closure was performed without difficulties, and the patient's condition was good at discharge. Closure of ASD is a simple and basic procedure in cardiac surgery but care must be taken not to leave a shunt at the lower part of the defect, especially in cases with ASD defects in the lower margin.
