ReviewCurrent evidence based guidelines for factor VIIa use in trauma: the good, the bad, and the ugly.
Recombinant factor VII (rFVIIa) has arisen as an option for the control of life-threatening traumatic bleeding unresponsive to other means. The timing of administration, dosage, mortality, units of blood transfusion saved, risk of thrombotic events, and risk/benefits ratio are presently poorly defined. A Medline search from 1995 through March 2008 was conducted. ⋯ There is Level I supporting the use of rFVIIa for blunt trauma patients only. There is no Class I evidence supporting decreased mortality or differences in thromboembolic events. Minimal effective dosing regimens and cost/benefit analyses have not yet been examined.

Pancreatic injuries are rare, with penetrating mechanisms being causative in majority of cases. They can create major diagnostic and therapeutic challenges and require multiple diagnostic modalities, including multislice high-definition computed tomography, magnetic resonance cholangiopancreatography, endoscopic retrograde cholangiopancreatography, ultrasonography, and at times, surgery and direct visualization of the pancreas. Pancreatic trauma is frequently associated with duodenal and other severe vascular and visceral injuries. ⋯ Wide surgical drainage is a key to any surgical trauma technique and access for enteral nutrition, or occasionally parenteral nutrition, are important adjuncts. Morbidity associated with pancreatic trauma is high and can be quite severe. Treatment of pancreatic trauma-related complications often requires a combination of interventional, endoscopic, and surgical approaches.

Case ReportsEarly thrombosis of the superior vena cava in a patient with a central venous catheter and carcinoma of the ampulla of Vater.
Superior vena cava syndrome results from obstruction of flow through the vessel either by external compression or thrombosis. External compression by intrathoracic neoplasms is the most common etiology. Thrombosis of the vessel most often occurs in the setting of indwelling catheters or pacemakers. ⋯ In this report, we present a patient who developed superior vena cava thrombosis after undergoing a short period of central venous catheterization and a Whipple procedure for adenocarcinoma of the ampulla of Vater. The endothelial damage caused by the catheter, the low-flow state induced by the large fluid shifts during the operation, and the hypercoagulable state induced by malignancy fulfill Virchow's triad for venous thrombosis. To our knowledge, this is the first reported case of superior vena cava syndrome after the Whipple procedure with symptoms appearing after a shorter period of catheterization than previously reported in the adult literature.
