However, the implications of AKI before thoracic endovascular aneurysm repair （TEVAR） of type B acute aortic dissection （AAD） remain unclear. This study evaluated the incidence, predictors, and in-hospital outcomes of AKI before TEVAR in patients with type B AAD. Methods Between 2009 and 2013, 76 patients were retrospectively evaluated who received TEVAR for type B AAD within 36 h from symptom onset. The patients were classified into no-AKI vs. AKI groups, and the severity of AKI was further staged according to kidney disease： im- proving global outcomes criteria before TEVAR. Results The incidence of preoperative AKI was 36.8%. In-hospital complications was significantly higher in patients with preoperative AKI compared with no-AKI （50.0% vs. 4.2%, respectively; P 〈 0.001）, including acute renal failure （21.4% vs. O, respectively; P 〈 0.001）, and they increased with severity of AKI （P 〈 0.001）. The maximum levels of body tem- perature and white blood cell count were significantly related to maximum serum creatinine level before TEVAR. Multivariate analysis showed that systolic blood pressure on admission （OR： 1.023; 95% CI： 1.003-1.044; P ： 0.0238） and bilateral renal artery involvement （OR： 19.076; 95% CI： 1.914 190.164; P = 0.0120） were strong predictors of preoperative AKI. Conclusions Preoperative AKI frequently occurred in patients with type B AAD, and correlated with higher in-hospital complications and enhanced inflammatory reaction. Systolic blood pressure on admission and bilateral renal artery involvement were major risk factors for AKI before TEVAR.展开更多

Case Report: We report the case of a 36-year-old with severe scoliosis status post repair over a decade ago, neurofibromatosis type I, and a known large meningocele in the left thoracic cavity, presenting with new acute respiratory compromise. She was taken to the operating room for a lumboperitoneal shunt, but the operation was aborted due to her severe spinal deformity. Two days later, she successfully underwent a procedure for ventriculoperitoneal shunt placement. Upon discharge a week later, the patient was hemodynamically stable, able to move all extremities with good strength, and demonstrated improved oxygenation. In the following 7 months, the patient demonstrated continued minimal requirement on nasal cannula, and MRI showed a stable left thoracic giant meningocele. Conclusion: Ventriculoperitoneal shunting is a method of treating and stabilizing acutely symptomatic giant meningoceles.展开更多
