New device for intraoperative graft assessment: HyperEye charge-coupled device camera system.
Our institution developed a new color chargecoupled device (CCD) camera system (HyperEye system) for intraoperative indocyanine green (ICG) angiography. The device consists of a combination of custommade optical filters and an ultra-high-sensitive CCD image sensor with non-Bayer color filter array (i.e., HyperEye technology), which can detect simultaneously color and near-infrared (NIR) rays from 380 to 1200 nm. Here, we demonstrate intraoperative graft assessment using the HyperEye system. ⋯ The HyperEye system can visualize any structural and functional failures. Our findings suggest that this device could become a useful tool for intraoperative graft assessment.

Case ReportsMediastinal teratoma complicated with acute mediastinitis.
We report a case of a mediastinal teratoma associated with acute mediastinitis that required an emergency operation. These tumors cause a variety of complications, but reports of acute mediastinitis are rare. A 24-year-old woman was admitted to our hospital for complaints of chest pain and fever and was subsequently diagnosed as having an anterior mediastinal tumor. ⋯ The histopathologic diagnosis was a mature teratoma that included pancreatic tissue. Although the apparent site of the rupture was not obvious, there was a wide area of acute inflammation in the mediastinal adipose tissue. The patient did well and was discharged from the hospital without major complications.
