In addition, ROC analysis was used to assess prediction results of the multivariate analysis.
Results: On univariate analysis 5 parameters were significant predictors of the type of repair, while on multivariate analysis only 3 parameters remained strong and independent predictors including the gapometry/urethrometry index, urethral gap length and prostatic displacement. The gapometry/urethrometry index was a proxy for all other parameters. At a cutoff index of 0.35 the appropriate surgical Sonidegib molecular weight repair was predicted with 91% specificity and a 95% positive predictive value.
When ROC analysis was performed the AUC was 0.979.
Conclusions: The type of anastomotic repair of pelvic fracture urethral distraction defect can be predicted by 3 preoperative
factors, namely the gapometry/urethrometry index, urethral gap length and prostatic displacement. The gapometry/urethrometry index has the highest predictive accuracy and is a proxy for all other factors. An index less than 0.35 indicates a simple perineal operation and an index greater than 0.35 indicates an elaborated perineal or a transpubic procedure.”
“INTRODUCTION: We evaluated the feasibility, usefulness, and limitations of near-infrared indocyanine green (ICG) videoangiography during procedures involving the extracranial vertebral artery (VA).
METHODS: Nine patients (2 women, 7 men; mean age, 55 years) were evaluated at 2 neurosurgical centers. Near-infrared ICG videoangiography was applied during transposition and rerouting of the first segment of VA (V1; n = 6) and during resection of neurinomas near the second (V2; n = 1) and
third (V3; n = 2) segments of VA.
RESULTS: Tanespimycin price Early after ICG injection, V1 fluoresced homogenously. The fluorescence of V2 and V3 varied. Without extrinsic compression, these segments appeared as noncontiguous hot spots because the VA runs freely in a periosteal sheath surrounded Aldehyde_oxidase by a venous plexus that attenuates the fluorescent light. Hot spots corresponded to areas where the artery neared the surface. With extrinsic compression, VA enhanced homogenously because it was pushed against the periosteal layer. During the late phase, the V1 signal was attenuated, whereas the venous plexus surrounding V2 and V3 enhanced homogeneously, thereby masking the VA itself. Near-infrared ICG videoangiography helped to confirm VA patency during transposition and rerouting but was not helpful during VA exposure because the periosteal sheath must already be exposed to detect the VA or its surrounding plexus. After exposure, videoangiography can help to determine the position of the VA within its periosteal sheath.
CONCLUSION: Videoangiography can be used to provide information about the patency of the VA and its location within the periosteal sheath to prevent injury during resection of tumor adherent to the periosteal sheath.”
