A 54-year-old woman underwent abdominal aortic replacement for abdominal aortic aneurysm in March 2012. Approximately 6 months after surgery, she was taken by ambulance to hospital due to thoracodorsal pain, lower limb paralysis and pain. Emergency computed tomography indicated acute aortic dissection involving the ascending aorta, aortic arch, and descending aorta. The outline of the prosthesis implanted in the abdominal aorta was absent, and emergency surgery was performed immediately by median sternotomy to treat suspected complete obstruction. Following confirmation of brachiocephalic artery dissection, extracorporeal circulation was started with drainage of blood from the vena cava and the return via left axillary artery, plus perfusion in both lower limbs. However, the level of regional oxygen saturation declined as the flow of extracorporeal circulation increased. To solve this problem, an incision was made in the ascending aorta, and an aortic cannula was inserted directly into the true lumen. Aortic arch replacement was then performed, but this central repair failed to improve blood flow in both the left and right femoral artery. Proximal thrombectomy successfully removed a large amount of thrombi, but did not improve blood circulation. Left axillobifemoral bypass was subsequently performed, and improved lower limb blood circulation, but with residual motor impairment. Since the patient regained somatosensory sensation and was able to perform simple exercises, rehabilitation was started. Hemodialysis was required after abnormal increases in muscle enzyme levels and white blood cell count, but this was later discontinued following improvement of renal function. The patient was transferred to a rehabilitation clinic 54 days after surgery.

Background:
/Aim: The aim of this study was to compare the therapeutic efficacy of ablation and surgery in solitary hepatocellular carcinoma (HCC) measuring ≤5 cm with a large HCC cohort database.
Methods:
The study included consecutive 2,067 patients with solitary HCC who were treated with either ablation (n=1,248) or surgery (n=819). Th e patients were divided into three groups based on the tumor size and compared the outcomes of the two therapies using propensity score matching.
Results:
No significant difference in recurrence-free survival (RFS) or overall survival (OS) was found between surgery and ablation groups for tumors measuring ≤2 cm or >2 cm but ≤3 cm. For tumors measuring >3 cm but ≤5 cm, RFS was significantly better with surgery than with ablation (3.6 and 2.0 years, respectively, P=0.0297). However, no significant difference in OS was found between surgery and ablation in this group (6.7 and 6.0 years, respectively, P=0.668).
Conclusion
The study suggests that surgery and ablation can be equally used as a treatment for solitary HCC no more than 3 cm in diameter. For HCCs measuring 3-5 cm, the OS was not different between therapies; thus, ablation and less invasive therapy can be considered a treatment option; however, special caution should be taken to prevent recurrence.

A 71-year-old man with Behçet's disease was admitted to our hospital for treatment of a thoracic aortic aneurysm. On admission, there was marked inflammatory response, but blood culture was negative and there was no significant accumulation of gallium scintigraphy. The aorta was shaggy and there were two aneurysms in the descending aorta. We performed endovascular aortic repair for this aneurysm in consideration of the inflammatory aortic aneurysm. After treatment, the patient had paraparesis, however he underwent physical rehabilitation to regain function. He was followed up for 1 year and remains in good clinical condition without anastomotic aneurysm, dilatation or aneurysm at another site.
