Comprehensive Computed Tomography Guidance of Coronary Bypass Graft Surgery
Apply CT angiography, CT perfusion imaging and advanced image processing techniques to improve revascularization decision-making and surgical strategies in patients undergoing coronary artery bypass graft surgery.
Cerebral Blood Flow in Neonates During Major Cardiac Surgery.
Rationale: During cardiac surgery, neonates are at high risk of cerebral damage: 36-78% will have new cerebral lesions after surgery. Adequate cerebral perfusion (CBF) is mandatory to prevent postoperative brain damage and neurobehavioral outcomes. For CBF, the systemic blood pressure should be managed above the brain's critical closing pressure (CrCP), …
Tracheal Tube and Swallowing After Head and Neck Surgery
The present study was designed as a cross-sectional observational study providing the enrollment of tracheostomized patients undergoing major oncological surgery for head-neck cancer. Aims to provide objective data on the bolus transit during swallowing in tracheostomized patients with tracheal tube and without tracheal tube closing directly the tracheal stoma with …
Glucose Homeostasis, Metabolomics and Pregnancy Outcomes After Bariatric Surgery
The aim of the GLORIA study is to determine whether an altered glucose metabolism (with more hypoglycaemia and glycaemic variability) and altered metabolomics during pregnancy after bariatric surgery contribute to the increased risk for adverse pregnancy outcomes such as small-for-gestational age infants. In addition, the investigators also aim to evaluate …
Multimodal Image Registration for Helping Laparoscopic Liver Surgery Guidance
Multimodal intraoperative minimal-invasive (laparoscopic or robotic) liver surgery images will be registered to each other. Explicitly, these are the ultrasound and laparoscope images. Once they are registered, they will reveal the hidden tumor's location to the surgeon in real time through augmented reality. The intraoperative augmentation will also be enriched …
An Audit of Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy
Peritoneal carcinomatosis is a common event in the natural history of colorectal and other digestive tract cancers. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) provides a promising therapeutic option for highly selected patients with peritoneal carcinomatosis arising from different malignancies such as colorectal cancer, gastric cancer, ovarian cancer, or …
Scleroderma Registry & Repository at the Hospital for Special Surgery
The overall objective of the Scleroderma Registry is to support and promote the basic science and clinical research of this complex rheumatic disease at the Hospital for Special Surgery (HSS). The registry facilitates our understanding of the clinical features, pathobiology, genetics of Scleroderma. This will ultimately lead to a potential …
Bone Marrow Fat and Bariatric Surgery-Mediated Bone Loss
Results are inconsistent and further studies are needed to better understand the impact of bariatric surgery on the bone-BMA relationship depending on the type of bariatric surgery: RYGB vs. SG. Future studies are also needed to define the molecular mediators of bone loss and BMA changes. Several molecular mediators have …
Investigate and Predict Aortic & Thoracic Surgery Persistenet Postsurgical Pain
This is an observational clinical study aiming to further the wider understanding of patients who develop persistent pain after Thoracoabdominal Aorta surgery, a surgical cohort who are disproportionately affected. This will be undertaken through a prospective biopsychosocial characterisation of the phenotype of patients undergoing this operation. Increasing numbers of patients …
OSA as a Remote Ischemic Preconditioning in Vascular Surgery
Ischemia and reperfusion (I/R) injury during abdominal aortic aneurysm (AAA) repair is inevitable and may lead to postoperative multi-organ failure. Remote ischemic preconditioning (short periods of ischemia in anticipation of longer period of ischemia) may act protectively against ischemia. Studies of ischemic preconditioning in patients with AAA are conflicting. Obstructive …
