Validation of the Chinese system for cardiac operative risk evaluation (SinoSCORE):the experience from Guangdong Cardiovascular Institute

Objective To validate of the Chinese system for cardiac operative risk evaluation (SinoSCORE) in Cantonese surgery patients. Methods Data from Guangdong Cardiovascular Institute in the period January 2004 through December 2008 were analyzed on 2462 Cantonese heart surgery patients. First,compared risk factors of this series and database of SinoSCORE,and then calculated

Methods Adult patients (age≤18 years) underwent valve surgery with preoperative serum creati nine 【 300 μmol / L were included between January 2005 and December 2008. Fifty patients developed ARF-D

Pleomorphic xanthoastrocytoma in the lateral ventricle with extensive subarachnoid dissemination： report of a case and review of the literature

Pleomorphic xanthoastrocytoma （PXA） is a rare benign tumor that is usually located in the superficial cerebral hemisphere.Most reports of PXAs have included only a single case or small series.Therefore,the data with respect to the natural history of this tumor are fragmentary.We report a case of a PXA in the unusual location of the right lateral ventricle with extensive subarachnoid dissemination.To our knowledge,this is a rare case of PXA in the lateral ventricle.In addition,extensive subarachnoid space dissemination of this distinctly benign type of glioma is exceedingly rare.In our case,there was meningeal dissemination and metastases to the bilateral trigeminal nerves and oculomotor nerves.The neuroradiographic features,tumor location,and dissemination were reviewed.

Procalcitonin could be a reliable marker in differential diagnosis of post-implantation syndrome and infection after percutaneous endovascular aortic repair

Background Thoracic endovascular aortic repair （TEVAR） is an emerging treatment moaality, wnicn nas been rapidly embraced by clinicians treating thoracic aortic disease. However, the clinical manifestations of systemic inflammatory response after TEVAR as post-implantation syndrome （PIS） resemble the perioperative infection. This study aimed to evaluate changes and diagnostic value of procalcitonin （PCT） and other traditional inflammatory markers for infections after TEVAR. Methods We conducted a prospective clinical study that enrolled 162 consecutive aortic dissection cases. who underwent TEVAR in our institution between July 2011 and November 2012. The PCT, C-response protein （CRP）, erythrocyte sedimentation rate （ESR） and blood routine examination were monitored before the operation and on days 1, 2, 3 and 5 after the operation. The diagnosis of infection was confirmed by the infection control committee with reference to Hospital Acquired Infection Diagnostic Criteria Assessment, released by the Ministry of Health of the People＇s Republic of China. Results Post endovascular repair of thoracic aorta, PCT changes significantly at different time points （X^2= 13.225, P=0.021）, without significant difference between the PIS group and the control group （0.24±0.04 vs.0.26±0.10, P=0.804）. PCT values were significantly higher in the first day after TEVAR than the preoperative levels （0.18±0.03 vs. 0.11±0.02, P 〈0.001）. Compared with PIS patients, the level of PCT, CRP, White blood cell （WBC） and neutrophil （NEU） in the infection patients elevated significantly （relatively X2=6.062, P=0.048; X2=6.081, P=0.048; X2=11.030, P=0.004; X2=14.632, P=0.001）. According to the ROC analysis, the PCT levels in the first day after TEVAR （AUC=0.785, P=0.012） had better predictive values of infection than WBC, NEU CRP and ESR （AUC=0.720, P=0.040; AUC=0.715, P=0.045; AUC=0.663, P=0.274; AUC=0.502, P=0.991）. The best predictive index was the changes of PCT between preoperative and postoperative （PCT）, which possess AUC as 0.803 （P=0.014）. And PCT=0.055 could be considered as an infection diagnosis cutoff value with a sensitivity of 83.3% and specificity 69.0%.

Changes of cerebrospinal fluid pressure after thoracic endovascular aortic repair

Background Decreasing the intracranial pressure has been advocated as one of the major protective strategies to prevent spinal cord ischemia after endovascular aortic repair. However, the actual changes of cerebrospinal fluid （CSF） pressure and its relation with spinal cord ischemia have been poorly understood. We performed CSF pressure measurements and provisional CSF withdrawal after thoracic endovascular aortic repair, and compared the changes of CSF pressure in high risk patients and in patients with new onset paraplegia and paraparesis.
