BACKGROUND Many institutions routinely perform intraoperative imaging during cochlear implant (CI) surgery to determine accurate electrode placement. Different modalities exist; however, there remains some controversy regarding the usefulness of intraoperative imaging. OBJECTIVE Systematically review the utility of intraoperative imaging in CI surgery and implications for management. METHOD...

BACKGROUND Acute unstable syndesmotic ankle injuries are treated primarily by reduction and stabilization with a syndesmotic screw. Examination with fluoroscopy or standard radiographs may not provide reliable information about the quality of the reduction. There is evidence that intraoperative three-dimensional imaging can demonstrate a large proportion of malreductions. The aim of this study ...

BACKGROUND Placenta previa, one of the most severe obstetric complications, carries an increased risk of intraoperative massive hemorrhage. Several risk factors for intraoperative hemorrhage have been identified to date. However, the correlation between birth weight and intraoperative hemorrhage has not been investigated. Here we estimate the correlation between birth weight and the occurrence ...

BACKGROUND Intraoperative pathologic diagnosis of bone and soft tissue lesions is an important yet challenging tool in clinical musculoskeletal oncology practice. There is limited information in the literature addressing the practical issues commonly encountered regarding intraoperative frozen section of musculoskeletal lesions. METHODS A literature review and retrospective review of practica...

OBJECTIVE The aim of this study is to evaluate the prognostic significance of intraoperative peritoneal lavage cytology (PLC) in pancreatic invasive ductal adenocarcinoma. METHODS Intraoperative PLC was evaluated in 162 patients with resectable pancreatic invasive ductal adenocarcinoma. The results were analyzed for correlations with clinicopathological parameters and/or prognoses. RESULTS ...

BACKGROUND Advances in surgical and in imaging technology permit the performance of complex tumour resections in a safe and oncologically correct manner. To date, this has mainly implicated refined preoperative imaging methods, such as three-dimensional computer-assisted planning (3D-CASP). With the advent of modern hybrid operating rooms, intraoperative imaging has spread and various technique...

Unexplained intraoperative coagulopathies continue to be a diagnostic and therapeutic dilemma. The pathophysiology behind unexplained intraoperative coagulopathies is of great variety and complexity (preexisting coagulopathies, dilutional coagulopathy, interactions of medications etc.). We have shown in prospective studies that patients undergoing elective surgery who develop "unexplained" intr...

Mitral valve repair provides substantial advantages over mitral valve replacement in patients with severe mitral regurgitation. However, because of the possibility of persistent regurgitation, an intraoperative technique is needed to provide an immediate and accurate assessment of the adequacy of the repair before closure of the chest. One hundred patients with pure mitral regurgitation were st...

Our goal was to improve image guidance during minimally invasive image guided therapy by developing an intraoperative segmentation and nonrigid registration algorithm. The algorithm was designed to allow for improved navigation and quantitative monitoring of treatment progress in order to reduce the time required in the operating room and to improve outcomes. The algorithm has been applied to i...

OBJECT The routine use of intraoperative angiography as an aid in the surgical treatment of aneurysms is uncommon. The advantages of the ability to visualize residual aneurysm or unintended occlusion of parent vessels intraoperatively must be weighed against the complications associated with repeated angiography and prolonged vascular access. The authors reviewed the results of their routine us...
