Dermal fillers have become increasingly popular as a cosmetic treatment for facial rejuvenation.Although these injections are generally considered to be safe,as the number of injections has increased,so has the rate of complications.Ischemic complications of fillers include vision loss,ophthalmoplegia,skin necrosis,and cerebral infarction.Knowing the anatomy well is critical to optimally prevent and manage these serious complications.Prevention includes knowledge of the vascular anatomy of the facial area,as well as certain injection techniques such as aspiration,use of a smaller needle,and adoption of a larger cannula.The use of ultrasound has been a recent innovation in preventing and treating filler complications as well.The reversibility of fillers should also be considered when choosing a filler.Some hyaluronic acid(HA)fillers,including the newer ones on the market,are difficult to reverse and non-HA fillers and fat are irreversible.This review aims to discuss facial anatomy,the various ischemic filler complications,the prevention and management of these complications,and the relatively recent use of imaging as an adjunct. 展开更多

BACKGROUND:Ischemia-related biliary tract complications remain high after orthotopic liver transplantation.Severe ischemic biliary complications often involve the hepatic duct bifurcation and left hepatic duct,resulting finally in obstructive jaundice.Prevention and management of such complications remain a challenge for transplant surgeons.METHODS:All 160 patients were followed up for at least 180 days after transplantation.One-way analysis of variance (ANOVA) and comparative univariate analysis were made using 3 groups (no complications;mild complications;severe complications),to analyze risk factors associated with biliary complications.Multiple logistic regression and linear regression analysis were used to analyze independent risk factors for severe ischemic biliary complications,after excluding other confounding factors.RESULTS:By ANOVA and comparative univariate analysis,the risk factors associated with biliary complications were preoperative bilirubin level (P=0.007) and T-tube stenting of the anastomosis (P=0.016).Multiple logistic regression analysis showed that the use of T-tube and preoperative serum bilirubin were not independent risk factors for severe ischemic biliary complications after orthotopic liver transplantation.Chi-square analysis indicated that in the incidence of severe ischemic biliary lesions,bile duct second warm ischemic time longer than 60 minutes was a significant risk factor.Linear regression demonstrated a negative correlation between cold preservation time and warm ischemia time.CONCLUSIONS:Preoperative serum bilirubin level and the use of T-tube stenting of the anastomosis were independent risk factors for biliary complications after liver transplantation,but not for severe ischemic biliary complications.The second warm ischemia time of bile duct longer than 60minutes and prolonged bile duct second warm ischemia time combined with cold preservation time were significant risk factors for severe ischemic biliary complications after liver transplantation with grafts from non-heart-beating donors. 展开更多

Background In-hospital medical complications are associated with poorer clinical outcomes for stroke patients after disease onset. However, few studies from China have reported the effect of these complications on the mortality of patients with acute ischemic stroke. In this prospective work, the China National Stroke Registry Study, we investigated the effect of medical complications on the case fatality of patients with acute ischemic stroke. Methods From September 2007 to August 2008, we prospectively obtained the data of patients with acute stroke from 132 clinical centers in China. Medical complications, case fatality and other information recorded at baseline, during hospitalisation, and at 3, 6, and 12 months after stroke onset. Multivariable Logistic regression was performed to analyze the effect of medical complications on the case fatality of patients with acute ischemic stroke. Results There were 39741 patients screened, 14526 patients with acute ischemic stroke recruited, and 11 560 ischemic stroke patients without missing data identified during the 12-month follow-up. Of the 11 560 ischemic patients, 15.8% (1826) had in-hospital medical complications. The most common complication was pneumonia (1373; 11.9% of patients), followed by urinary tract infection and gastrointestinal bleeding. In comparison with patients without complications, stroke patients with complications had a significantly higher risk of death during their hospitalization, and at 3, 6 and 12 months post-stroke. Having any one in-hospital medical complication was an independent risk factor for death in patients with acute ischemic stroke during hospital period (adjusted OR=6.946; 95% CI 5.181 to 9.314), at 3 months (adjusted OR=3.843; 95% C/3.221 to 4.584), 6 months (adjusted OR=3.492; 95% CI 2.970 to 4.106), and 12 months (adjusted OR= 3.511; 95% CI 3.021 to 4.080). Having multiple complications strongly increased the death risk of patients. Conclusion Short-term and long-term outcomes of acute stroke patients are affected by in-hospital medical complications. 展开更多

BACKGROUND Pancreaticoduodenectomy(PD)has been increasingly performed as a safe treatment option for periampullary malignant and benign disorders.However,the operation may result in significant postoperative complications.Here,we present a case that recurrent pyogenic liver abscess after PD is caused by common hepatic artery injury in atypical celiac axis anatomy.CASE SUMMARY A 56-year-old man with a 1-d history of fever and shivering was diagnosed with hepatic abscess.One year and five months ago,he underwent PD at a local hospital to treat chronic pancreatitis.After the operation,the patient had recurrent intrahepatic abscesses for 4 times,and the symptoms were relieved after percutaneous transhepatic cholangial drainage combining with anti-inflammatory therapy in the local hospital.Further examination showed that the recurrent liver abscess after PD was caused by common hepatic artery injury due to abnormal abdominal vascular anatomy.The patient underwent percutaneous drainage but continued to have recurrent episodes.His condition was eventually cured by right hepatectomy.In this case,preoperative examination of the patient’s anatomical variations with computed tomography would have played a pivotal role in avoiding arterial injuries.CONCLUSION A careful computed tomography analysis should be considered mandatory not only to define the operability(with radical intent)of PD candidates but also to identify atypical arterial patterns and plan the optimal surgical strategy. 展开更多
