To establish guidelines for the surgical treatment of patients with infective endocarditis who have cerebrovascular complications, we conducted a detailed retrospective study of 181 of 244 patients with cerebral complications among 2523 surgical cases of infective endocarditis of the Japanese Association of Thoracic Surgery. The results showed that 9.7% of all patients with infective endocarditis had associated cerebral complications: 108 (44.3%) had active native valve endocarditis, 96 (39.3%) had healed native valve endocarditis, and 40 (16.4%) had prosthetic valve endocarditis. The hospital mortality of the patients with cerebral complications was 11.0% in the group as a whole: 13.9% in active native valve endocarditis, 3.1% in healed native valve endocarditis, and 37.5% in prosthetic valve endocarditis. Diseased valves included the following aortic valve in 55.5%, mitral valve 49.8%, tricuspid valve in 1.3%, and pulmonary valve in 1.3%. In 181 patients with cerebral complications, organisms were detected as follows: gram-positive cocci in 133 (73.5% [Streptococcus in 85, Staphylococcus in 32]), gram-negative in 18 (9.9%), fungus in 11 (6.1%), and unknown in 64.6%, cerebral bleeding in 31.5%, cerebral abscess in 2.8%, and meningitis in 1.1%. Hospital mortality rate and an exacerbation rate of cerebral complications, including related death, according to the interval from onset of cerebral infarction to cardiac surgery, were as follows: 66.3% and 45.5% within 24 hours, 31.3% and 43.8% between 2 and 7 days, 16.7% and 16.7% between 8 and 14 days, 10.0% and 10.0% between 15 and 21 days, 26.3% and 10.5% between 22 and 28 days, and 7.0% and 2.3% over 4 weeks later, respectively. A significant correlation existed between the interval and the exacerbation of cerebral complications (tied p = 0.008). Preoperative risk factors affecting exacerbation of cerebral complications were as follows: (1) severity of cerebral complications (p = 0.006), (2) intervals (p = 0.012), and (3) uncontrolled congestive heart failure as indications for cardiac surgery (p = 0.014). One patient underwent a cardiac operation within 24 hours of the onset of cerebral hemorrhage and died of cerebral damage. No exacerbations occurred in 10 patients who underwent their operation between 2 and 28 days. Nevertheless, exacerbations occurred in 19.0% of patients whose operation was done more than 4 weeks later. These data suggest that cardiac operations can be done safely 4 weeks after cerebral infarction, and if the delay is more than 2 weeks, the exacerbation rate will be around 10%. The risk of progression of cerebral damage is still significant 15 days and even 4 weeks after cerebral hemorrhage.

A 71-year-old man with a retroperitoneal abscess caused by a ureteral stone was successfully treated by retroperitoneal drainage. He was considered to be at high risk of infection because of his bedridden state (resulting from a post-cerebral infarction and malignant rheumatoid disease) and steroid administration for the rheumatoid disease. He also had an empyema adjacent to the retroperitoneal abscess. This was thought to be separate from the retroperitoneal abscess because it did not resolve after the retroperitoneal drainage. Thoracic cavity drainage was undertaken, after which the empyema disappeared. The drainage fluid contained pus, similar to the fluid from the retroperitoneal drainage. Escherichia coli organisms were cultured from both drainage fluids. There were no signs of recurrence on computed tomography (CT) imaging. In conclusion, we report a case of retroperitoneal abscess perforating into the thorax, successfully treated by retroperitoneal and thoracic cavity drainage in an immunocompromised host. CT was a very effective imaging modality for this diagnosis, and we recommend early drainage of abscess in immunocompromised patients.

We report the case of a systemic air embolism occurring during pulmonary radiofrequency ablation. At the end of the procedure, the patient experienced a sudden myocardial infarction, complicated by ventricular fibrillation, cardiac arrest, and cerebral infarction. Thoracic computed tomography showed an air-blood level inside the left atrium and ventricle, the aortic arch, and the coronary arteries. Cerebral computed tomography showed an infarct in the frontoparietal area. Myocardial infarction and stroke responded to resuscitation measures, including hyperbaric oxygenation. The occurrence of this life-threatening event confirms the need to train experienced anesthesiologists in these new invasive approaches to cancer treatment.

Thoracic endovascular aneurysm repair(TEVAR) has been applied more and more frequently to an atherosclerotic distal aortic arch aneurysm. Even if the procedure is successful, extensive cerebral infarction might occur, especially in the left vertebral artery area. We therefore devised a new method to prevent embolic events using a thrombectomy catheter with an end hole, which was placed at the origin of the letf subclavian artery via the radial artery. This simple left subclavian artery balloon technique not only prevents cerebral embolism in the left vertebral artery system, but also provides a position marker under X-ray, and enables tight compaction of the embolization coils.

Thoracic endovascular aortic repair( TEVAR) for thoracic aortic aneurysm has been established as a 1st-line therapy, especially in high-risk cases, with device improvements and the appearance of various procedures, but there are still cases of anatomical adaptation. On the other hand, several countermeasures have been developed, but there are no commercially available devices for fenestrated or branched stent grafts in Japan. Moreover, complications such as cerebral infarction, organ ischemia and bypass occlusion and infection are pointed out in popular debranch TEVAR. However the surgeon-modified fenestrated TEVAR can extend the landing zone without open thoracotomy and laparotomy, and can reduce the operation time by decreasing debranch branches. And by the use of a commercially available device, is an urgent correspondence is possible surgical procedures. We report our treatment strategies including experience of 29 cases( Relay Plus:13 cases, Cook TX2:16 cases) of surgeon-modified fenestrated TEVAR that we implemented.
