ET1 Concentration, Metabolic Pathway Activation, and Pulmonary Blood Flow in Infants Undergoing Superior Cavo-Pulmonary Anastomosis
This is a novel preliminary study of biomarkers of pathologic pre-operative pulmonary vascular development, elevated pre-operative Pulmonary Vascular Resistance Index (PVRi), and complications associated with decreased post-operative pulmonary blood flow in single ventricle patients undergoing superior cavo-pulmonary anastomosis (SCPA). The study will utilize a combined targeted and untargeted approach to …
Ultrasonography in the Diagnosis of Nasal Fractures
The purpose of this cross-sectional prospective observational study is to determine the efficacy of high-resolution ultrasonography in identifying and characterizing nasal bone fractures in adult patients with recent facial trauma. The primary questions it aims to answer are: Can high-resolution ultrasonography effectively detect nasal bone fractures? Is high-resolution ultrasonography capable …
Patient-specific Planning of Minimally Invasive Brain Interventions Based on Vascular-hemodynamic Mapping
Endovascular procedures for treating brain aneurysms and arteriovenous malformations (AVMs) are becoming increasingly popular due to their less invasive nature and lower risk of complications. However, they still face challenges such as difficult catheter navigation and incomplete embolization. This study aims to improve the efficiency and safety of endovascular procedures …
Orthognathic Speech Pathology: Phonetic Contrasts of Patients With Dental Discrepancies Pre- and Post-Treatment Analyses
The investigators are studying how speech is effected by jaw and tooth position in jaw surgery patients. Eighty percent of our jaw surgery patients have speech pathologies, compared to five percent of the general population, but speech pathologists do not understand why. The investigators hypothesize that open bites and underbites …
DRug-coAted Balloon Compared With cuttinG balloON in Treatment of Arteriovenous Fistula Stenosis
The purpose of this clinical trial is to compare the efficacy and safety of cutting balloons versus drug-coated balloons in treating venous stenosis of autologous arteriovenous fistulas.The main questions it aims to answer are: Will drug-coated balloons achieve a better CD-TLR rate compared to cutting balloons? What medical problems do …
Intraoperative Laser Speckle Contrast Imaging of Cerebral Blood Flow
The purpose of this research study is to evaluate the ability of laser speckle contrast imaging to visualize blood flow in real time during neurosurgery. Real-time blood flow visualization during surgery could help neurosurgeons better understand the consequences of vascular occlusion events during surgery, recognize potential adverse complications, and thus …
AOrtic Surgery: Systemic Inflammatory Response Versus Sepsis
The goal of the prospective observational study is to evaluate the immunological background of inflammatory response often seen after open thoracic aortic surgery. Patients scheduled for this type of procedure will undergo a series of blood testing (preoperatively, and several times postoperatively). The blood samples will be used for a …
Congenital Lung Anomalies (CLA) Swiss Database
Congenital lung anomalies include different pathologies such as congenital cystic adenomatoid malformation, pulmonary sequestration, bronchial atresia, emphysema, bronchogenic cyst. They concern less than 1/10000 births and their physiopathological origin is still poorly understood. The main goal of this project is to pool the cases from different swiss centers on a …
NIRS in Congenital Heart Defects - Correlation With Echocardiography
Neonatal patients with congenital heart defects (CHD) have changing physiology in the context of transitional period. Patients with CHD are at risk of low perfusion status or abnormal pulmonary blood flow. Near infrared spectroscopy has been used in neonatal intensive care units (NICU) to measure end-organ perfusion. The investigator plan …
Intraoperative Monitoring for the Lateral Lumbar Interbody Fusion Procedure
This study is designed to evaluate the clinical utility of a known intraoperative neuromonitoring modality (SSEP) using saphenous nerve as the site of stimulation to identify changes to the lumbar nerves which may be at risk during the lateral lumbar interbody fusion (LLIF) procedure.
