ABSTRACT
Objective The clinical manifestations of cerebral infarction caused by acute basilar arterial occlusion are complex.The purpose of this study is to explore the relationship between lesion location and onset symptoms of cerebral infarction caused by acute basilar arterial occlusion.Methods Fifty three patients diagnosed with cerebral infarction caused by acute artery occlusion were collected from Nanjing Stroke Registry.They were hospitalized in Jinling Hospital from January 2007 to July 2016 and were divided into sudden onset group and progressive onset group.Their clinical and digital subtraction angiography data were analyzed retrospectively.Results Middle and distal segment of the basilar artery occlusions were usually found in sudden onset group.Patients in progressive onset group were more likely to present with proximal segment of the basilar artery occlusions.Significant statistical difference was found between two groups (P<0.05).Logistic regression analysis showed that the symptoms of patients with proximal segment basilar artery occlusion tended to be progressive onset, compared with patients affected by distal segment occlusion (OR=14.77,95%CI:1.57-139.00, P=0.019).Conclusion There was significant relationship between lesion location and onset symptoms of cerebral infarction caused by acute basilar arterial occlusion.Early diagnosis and timely treatment may improve clinical prognosis in patients.
ABSTRACT
Objective To investigate the type,clinical and imaging features of iatrogenic bile duct injury and the efficacy and safety of endoscopic and interventional radiology therapy.Methods A total of 48 patients with iatrogenic bile duct injury who have undergone endoscopic and/or interventional therapy from January 1st 2013 to June 30th 2016 were enrolled.Patients' general information,causes of injury,clinical manifestations,treatment methods,efficacy and complications were retrospectively analyzed.Results The causes of iatrogenic bile duct injury were cholecystectomy(45.8%,22/48),liver transplantation (35.4%,17/48),transjugular intrahepatic portosystemic shunt (8.3%,4/48),Roux-en-Y anastomosis (6.3%,3/48) and endoscopic retrograde cholangiopancreatography (4.2%,2/48).The most common type of iatrogenic bile duct injury was stenosis of intra/extra bile ducts (66.7%,32/48).Other types included biliary fistula(18.8%,9/48),hemobilia (10.4%,5/48) and stenosis of anastomotic stoma (4.2%,2/48).The most common clinical manifestations were jaundice (37.5%,18/48) and abdominal pain (29.2%,14/48).Other clinical manifestations were fever (14.6%,7/48),hematemesis or melena (8.3%,4/48) and abnormal drainage fluid (8.3%,4/48).Diagnosis was confirmed by angiography,cholangiography or endoscopy.The overall effective rate of minimally invasive therapy was 91.7% (44/48) and the most common complications were fever (16.7%,8/48) and pancreatitis (10.4%,5/48).Other complications were hemobilia (2.1%,1/48),cardia dilaceration (2.1%,1/48) and biliary fistula caused by catheter shedding(2.1%,1/48).Conclusion Iatrogenic bile duct injury could occur after upper abdominal surgeries,endoscopic or interventional procedures.Early diagnosis and treatment with endoscopic or vascular interventional methods can achieve satisfying efficacy and safety.
