Pose Estimation of Periacetabular Osteotomy Fragments with Intraoperative X-Ray Navigation [PDF]

IEEE Transactions on Biomedical Engineering, vol. 67, no. 2, pp. 441-452, Feb. 2020, 2019
Objective: State of the art navigation systems for pelvic osteotomies use optical systems with external fiducials. We propose the use of X-Ray navigation for pose estimation of periacetabular fragments without fiducials. Methods: A 2D/3D registration pipeline was developed to recover fragment pose.

Period-dependent Associations between Hypotension during and for Four Days after Noncardiac Surgery and a Composite of Myocardial Infarction and Death: A Substudy of the POISE-2 Trial

Anesthesiology, 2017
Background: The relative contributions of intraoperative and postoperative hypotension to perioperative morbidity remain unclear. We determined the association between hypotension and a composite of 30-day myocardial infarction and death over three ...

Sufentanil versus fentanyl in intraoperative and postoperative periods in pediatric patients

Critical Care, 2006
In our study we compared sufentanil vs fentanyl in children undergoing Lich–Gregoir antireflux plasty. The aim of this study was to evaluate and compare the hemodynamic parameters during anesthesia as well as the time of extubation of both opioid analgesics.

Flexible 3D Kirigami Probes for In Vitro and In Vivo Neural Applications

Advanced Materials, EarlyView.
A customizable and scalable approach to fabricate flexible 3D kirigami microelectrode arrays (MEAs) featuring up to 128 shanks, including surface and penetrating electrodes designed to interact with the 3D space of neural tissue, is presented. The 3D kirigami MEAs are successfully deployed in several neural applications, both in vitro and in vivo, and ...

Registration of ultrasound volumes based on Euclidean distance transform [PDF]

, 2020
During neurosurgical operations, surgeons can decide to acquire intraoperative data to better proceed with the removal of a tumor. A valid option is given by ultrasound (US) imaging, which can be easily obtained at subsequent surgical stages, giving therefore multiple updates of the resection cavity.

Intraoperative optical mapping of epileptogenic cortices during non-ictal periods in pediatric patients

NeuroImage: Clinical, 2016
Complete removal of epileptogenic cortex while preserving eloquent areas is crucial in patients undergoing epilepsy surgery. In this manuscript, the feasibility was explored of developing a new methodology based on dynamic intrinsic optical signal imaging (DIOSI) to intraoperatively detect and differentiate epileptogenic from eloquent cortices in ...

Prediction of suboptimal cytoreductive surgery in patients with advanced ovarian cancer based on preoperative and intraoperative determination of the peritoneal carcinomatosis index

World Journal of Surgical Oncology, 2018
BackgroundThe peritoneal carcinomatosis index (PCI) can be used to quantify the tumor burden in patients with advanced ovarian cancer. The aim of the present study was to establish a predictive model for suboptimal cytoreductive surgery (SCS) (residual ...
