A homotopy-based sparse representation for fast and accurate shape prior modeling in liver surgical planning
Shape prior plays an important role in accurate and robust liver segmentation. However, liver shapes have complex variations and accurate modeling of liver shapes is challenging. Using large-scale training data can improve the accuracy but it limits the computational efficiency. In order to obtain accurate liver shape priors without sacrificing the efficiency when dealing with large-scale train...
متن کاملQuantitative radiology: automated CT liver volumetry compared with interactive volumetry and manual volumetry.
OBJECTIVE The purpose of this study was to evaluate automated CT volumetry in the assessment of living-donor livers for transplant and to compare this technique with software-aided interactive volumetry and manual volumetry. MATERIALS AND METHODS Hepatic CT scans of 18 consecutively registered prospective liver donors were obtained under a liver transplant protocol. Automated liver volumetry ...
متن کاملEffects of liver cirrhosis on portal vein embolization prior to right hepatectomy in patients with primary liver cancer
Preoperative portal vein embolization (PVE) induces compensatory hyperplasia of the future liver remnants (FLR), thus increasing resectability in the non-cirrhotic patients with primary liver cancer (PLC). However, it is unclear if it is similar in patients with liver cirrhosis. Therefore, the present study investigated the PVE value prior to liver resection in patients with PLC, and the liver ...
متن کاملPost-hepatectomy liver failure.
Hepatectomies are among some of the most complex operative interventions performed. Mortality rates after major hepatectomy are as high as 30%, with post-hepatic liver failure (PHLF) representing the major source of morbidity and mortality. We present a review of PHLF, including the current definition, predictive factors, pre-operative risk assessment, techniques to prevent PHLF, identification...
متن کاملClinical effect of ischemic preconditioning prior to hepatectomy
Objective: This study evaluated the effect and clinical value of hepatic ischemic preconditioning (IP) prior to hepatectomy. Methods: 458 patients who underwent liver resection from 2001 to 2014 at Xijing Hospital were retrospectively analyzed. The patients were divided into two groups. From 2001 to 2005, the Pringle maneuver was primarily used for hepatic inflow occlusion, and 223 patients wer...
