This paper presents a method towards inferring personalized 3D spine models to intraoperative CT data acquired for corrective spinal surgery. An accurate 3D reconstruction from standard X-rays is obtained before surgery to provide the geometry of vertebrae. The outcome of this procedure is used as basis to derive an articulated spine model that is represented by consecutive sets of intervertebr...

OBJECTIVE Intraoperative blood loss in patients undergoing oncological spine surgery poses a major challenge for vulnerable patients. The goal of this study was to assess how the surgical procedure, tumor type, and anatomy, as well anesthesiological parameters, affect intraoperative use information generate short preoperative checklist surgeons anesthesiologists identify at risk increased loss....

BACKGROUND To date, few parameters have been found that can aid in patient selection and surgical strategy for eloquent area gliomas. AIMS The aim of the study was to analyze preoperative and intraoperative factors that can predict functional outcome and extent of resection in eloquent area tumors. PATIENTS AND METHODS A retrospective analysis was conducted on 60 patients harboring supraten...

ultrasound-conductive substance (e.g., water, pus, blood, and fibrous tissue), the withdrawal of air (e.g., resorption atelectasis) will also lead to the genesis of B lines. Demonstrating this last point, in an ex vivo animal model of graded atelectasis, B lines were observed in increasing numbers with increasing atelectasis. Pathologic examination of the excised lungs showed diffusely compress...

OBJECTIVE To describe which obstetric patients lose enough blood during postpartum hemorrhage to receive a reinfusion of intraoperative blood salvage. METHODS Eight years of intraoperative blood salvage data from a regional tertiary care maternity hospital were analyzed. The volume of blood returned through intraoperative blood salvage was standardized to the volume of red blood cells in an a...

background one of the major problems in surgery is intraoperative bleeding which reduces visibility in the operative field. an important task for an anesthetist during head and neck surgery is to improve intraoperative visibility. objectives the purpose of this study was to compare the amount of bleeding using different doses of oral metoprolol during three common types of nasal operation; rhin...

conclusions premedication with clonidine to decrease intraoperative blood loss can be more effective in patients with opium addiction than the ones without addiction. results intraoperative blood loss in clonidine recipient groups, patients with and without addiction, was less than that of the placebos (both p values < 0.01) and the difference magnitude was higher in patients with opium addicti...

BACKGROUND In off-pump coronary artery bypass surgery, manipulations on the beating heart can lead to transient interruptions of myocardial oxygen supply, which can generate an accumulation of oxygen-dependent metabolites in coronary venous blood. The objective of this study was to evaluate the reliability of intravascular near-infrared spectroscopy as a monitoring method to detect possible isc...

Many hypothesize that subtle inflammation and immune activity detected in the intraoperative period are linked to adverse postkidney transplant clinical outcomes. To this end, renal allografts were analyzed for expression of pro-inflammatory, inflammation-induced adhesion molecules, immune activation as well as anti-apoptotic genes expressed 15 min after vascular reperfusion (zero-hour) to dete...

The ideal surgical treatment of giant liver hemangioma is still controversial. This study aims to compare the outcomes of enucleation with those of resection for liver hemangioma larger than 10 cm in different locations of the liver and establish the preoperative predictors of increased intraoperative blood loss.Eighty-six patients underwent enucleation or liver resection for liver hemangioma l...
