Surgical treatment for ruptured aneurysm of distal arch or aortic arch: report of three cases

We experienced three cases of surgery for ruptured aneurysm of the distal aortic arch (2 cases) or aortic arch (1 case). A 59-year-old man who was diagnosed as distal arch aneurysm ruptured to the pericardial cavity underwent graft replacement of the aneurysm and reconstruction of a left subclavian artery under selective cerebral perfusion (SCP). This patient had left hemiplegia postoperatively. A 73-year-old man who was diagnosed as an aneurysm of distal arch and descending aorta ruptured to left pleural cavity underwent graft replacement of the aneurysm and reconstruction of a left subclavian artery under SCP, and died of severe left ventricular failure possibly due to preoperative myocardial ischemia. A 70-year-old man who was diagnosed as a saccular aneurysm of aortic arch ruptured to mediastinum underwent resection of the aneurysm and patch plasty of the aorta under SCP. The postoperative course was uneventful. We discussed the approach to aneurysm, adjunctive method and surgical precedures from standpoint of our ruptured three cases.
