Aortic rupture and transection are constituents of the acute aortic syndrome. Injury to the thoracic aorta during motor vehicle crashes is associated with blunt chest trauma and rapid deceleration mechanisms. Type A dissections and/or rupture of the aorta at the level of the aortic isthmus are the more common presentations of aortic injuries associated with motor vehicle crashes. We present the case of atypical echocardiographic findings of a nearly complete circumferential transection of the proximal ascending aorta injury after a motorcycle crash.

Background Sufficient evidence suggests that preoperative biliary stenting is associated with increased complication rates after pancreaticoduodenectomy. Methods Surveillance, Epidemiology, and End Results (SEER) and linked Medicare claims data (1992–2007) were used to identify patients with pancreatic cancer who underwent pancreaticoduodenectomy. We evaluated trends in the use of preoperative biliary stenting, timing of physician visits relative to stenting, and time to surgical resection and symptoms in stented and unstented patients. Results Pancreaticoduodenectomy was performed in 2,573 patients, and 52.6% of patients underwent preoperative biliary stenting (N = 1,354). Of these, 75.3% underwent endoscopic stenting only, 18.9% received a percutaneous stent, and 5.8% underwent both procedures. The overall stenting rate increased from 29.6% of patients between 1992 and 1995 to 59.1% between 2004 and 2007 (P Conclusion Use of preoperative biliary stenting doubled between 1992 and 2007 despite evidence that stenting is associated with increased perioperative infectious complications. The majority of stenting occurred prior to surgical consultation and is associated with significant delay in time to operation. Surgeons should be involved early in order to prevent unnecessary stenting and improve outcomes.
