ABSTRACT
Case 1 is a 70-year-old male. He has a history of cholelithiasis and left inguinal hernia. A preoperative examination of the inguinal hernia showed the enlargement of the mediastinal shadow, and he was referred to our department. A close examination revealed a right-sided aortic arch, a right descending aorta, and a descending aortic diverticulum. No subjective symptoms, intracardiac malformations, or other cardiovascular diseases were observed. The surgery was scheduled for descending aorta replacement including a diverticulum with right posterior lateral 4th intercostal thoracotomy and lower body partial extracorporeal circulation. However, due to aortic intima injury at the proximal end, hypothermic cerebral circulatory arrest and proximal anastomosis were performed by the open proximal method. There was no problem with the postoperative course, and he was discharged 19 days after surgery. Case 2 is a 51-year-old female. Born in China, she has lived in Japan for 15 years. No notable history. An abnormal shadow was shown on chest Xp performed in a medical examination, and aortic malformation was suspected on chest CT. She was referred to our department. The diagnosis was right-sided aortic arch, right descending aorta, aberrant left subclavian artery, and Kommerell diverticulum. There were no subjective symptoms and no intracardiac malformations. The operation was a two-stage operation. As the initial surgery, median sternotomy was performed, total arch replacement with intrathoracic reconstruction of the left subclavian artery, and open stent graft insertion, and the Kommerell diverticulum was covered with an open stent graft. We did not treat the diverticulum because it was located on the dorsal side. At 15 days after surgery, we performed embolization of the origin of the left subclavian artery from the Kommerell diverticulum. There was no problem with the postoperative course, and she was discharged 19 days after the initial surgery.
