The median sternotomy approach for the treatment of chronic pulmonary thromboembolism was recently improved by Daily, Jamieson, and coworkers who adopted it for use under cardiopulmonary bypass with intermittent circulatory arrest; however, we have sometimes found that the circulatory arrest time was too short to complete thromboendarterectomy. Therefore, we attempted to perform a selective cerebral perfusion technique to extend the endarterectomy time. Although we noted slight back-bleeding from the bronchial arteries, we were able to extend the endarterectomy time without causing any postoperative delirium. We conclude that the median sternotomy approach using cardiopulmonary bypass with selective cerebral perfusion may be the best option for extending the thromboendarterectomy time.

We report the case of a patient who underwent treatment for a macroembolism in the right lower leg, which led to shaggy aorta syndrome. Anticoagulant therapy for the macroembolism and intra-aortic catheterization exacerbated the patient's renal function and triggered another massive microembolization of the visceral arteries, with a fatal outcome. To minimize the incremental complications inherent to this syndrome, awareness and prompt diagnosis with enhanced computed tomography or intravenous digital subtraction aortography are essential. Axillo-bifemoral bypass with bilateral external iliac artery ligations, performed with optimal timing, could save patients with shaggy aorta syndrome.

(1) Wound hypoesthesia and numbness displayed a high incidence. (2) Atrophy of the abdominal wall muscle in the incision side was found in these patients. (3) The cause of AB is considered to be muscle atrophy induced by denervation injury of an 11th intercostal nerve. (4) To avoid an eleventh intercostal nerve injury must be deemed the most effective method for preventing AB.

A 52-year-old man was referred to our institution because of a solitary aneurysm of the left common iliac artery. The presence of the aneurysm was demonstrated by CT and angiography. The aneurysm had a diameter of about 30mm. The walls of the bilateral external iliac arteries were irregular, like a string of beads. The aneurysm was resected and replaced with a vascular prosthesis. Histological examination of the aneurysm and a part of the left external iliac artery indicated a diagnosis compatible with fibromuscular dysplasia (FMD: medial fibroplasia). A solitary iliac aneurysm is rare, and is usually due to atherosclerosis.However, the aneurysm in this case was related to FMD. To the best of our knowledge, only one other case of a solitary common iliac aneurysm caused by FMD has so far been described.
