In another 30-year-old male patient, the entire course of a calcified LA was demonstrated using multidetector row computed tomography.展开更多

We report a case of a young morbidly obese patient who underwent sleeve gastrectomy that was complicated by a postoperative leak at the level of the gastroesophageal junction. A covered esophageal stent was placed endoscopically to treat the leak. The pa-tient developed massive upper gastrointestinal bleeding secondary to the erosion of the stent into an aberrant retroesophageal right subclavian artery twelve days after stent placement. She was ultimately treated by endovascular stenting of the aberrant right subclavian artery followed by thoracotomy and esophageal repair over a T-tube. This case report highlights the multidis-ciplinary approach needed to diagnose and managesuch a devastating complication. It also emphasizes the need for imaging studies prior to stent deployment to delineate the vascular anatomy and rule out the possi-bility of such an anomaly in view of the growing popu-larity of esophageal stents, especially in the setting of a leak.展开更多

It is diagnosed as nonvisualization of LSCA in catheterization study. Case Presentation: Here we report an unusual case of Tetralogy of Fallot (TOF) with right aortic arch with isolation of left subclavian artery (LSCA). Here LSCA originated from left pulmonary artery (LPA) through an atretic patent ductus arteriosus (PDA). There was nonvisualization of LSCA in catheterization study and it was confirmed by Computed Tomography (CT) angiography. Re-implantation of LSCA was done to left common carotid artery (LCCA) so that the left upper arm maintains a better flow in the future. Conclusion: Isolation of LSCA especially with TOF is a very rare entity. Re-implantation of LSCA to LCCA was done in view of weak pulses in left upper limb. Results were satisfactory in the follow up period.展开更多

文摘The standard surgery for distal common bile duct adenocarcinoma,pancreatic adenocarcinoma,and ampullary adenocarcinoma is pancreaticoduodenectomy(PD).PD is a technically challenging procedure with high mortality(0-3.5%)and morbidity(38-50%)rates(1-5).It is essential to recognize the anatomy preoperatively,especially of the hepatic artery and positions of the tumors,to avoid adverse events(6,7).The aberrant right hepatic artery(aRHA)originating from the superior mesenteric artery(SMA)is the most frequent and considerable hepatic artery variation(8-10).
