A 95-year-old man suffered repeated episodes of loss of consciousness. Ruptured abdominal aortic aneurysm with giant retroperitoneal hematoma was diagnosed by computed tomography scans, and was referred to our hospital for surgical management. As he was about to be transported cardiopulmonary arrest developed, and emergency operation was started under resuscitation for pulseless electrical activity condition. We found a left common iliac artery aneurysm intraoperatively. We improved his hemodynamics by clamping the infrarenal abdominal aorta, and performed replacement of the left common iliac artery with a tube graft as quickly as possible. We inserted an intestinal drainage tube because of the expected high intraperitoneal pressure which caused by marked edema of the intestinal tract. He was weaned from respiratory support on the 5th postoperative day. He could walk on his own and was successfully discharged on the 28th postoperative day.

Type B intramural hematoma (IMH) is not considered to be a life-threatening condition, and medical treatment is the first treatment choice. We report 2 cases of ruptured type B intramural hematoma. Total arch replacement was performed via median sternotomy, which is not a common surgical strategy for type B dissection. Case 1 : a 77-year-old woman was transferred to our hospital with chest and back pain. CT revealed type B IMH with a large hematoma in the anterior mediastinum. She underwent total arch replacement, but she died of respiratory failure on the 167th postoperative day. Case 2 : a 60-year-old man was transferred to our hospital with chest and back pain. CT revealed a type B IMH with a large hematoma on the anterior side of the arch. He underwent total arch replacement, but died of sepsis on the 13th postoperative day. We had 2 rare cases of ruptured type B IMH. In both cases, postoperative courses were problematic. However, median sternotomy could be an approach for ruptured type B dissection in some cases.

Infected thoracic aortic aneurysms are rare. Standard treatment methods have not yet been established for medical treatment, timing of surgery, or surgical techniques. In this study, we report a case in which an ascending aortic reconstruction using an autologous superficial femoral artery was successfully performed for an infected pseudoaneurysm of the thoracic aorta without the use of artificial materials. The patient was a 78-year-old man with bacteremia caused by Staphylococcus aureus and an infected pseudoaneurysm of the thoracic aorta. The patient underwent replacement of the ascending aorta and coronary artery bypass grafting. The patient was discharged from the hospital with no recurrence of infection and no abnormality of the reconstructed aorta.
