A cerebrospinal fluid hydrothorax is a very rare complication following ventriculoperitoneal (VP) shunt and usually reported in children. We report a case of 47-year-old woman who developed massive hydrothorax and respiratory distress following intrathoracic migration of distal shunt catheter. After the confirmation of catheter in thoracic cavity using radionuclide shuntogram, the patient was successfully treated with laparoscopic shunt catheter reposition.

Background: An effectively functioning arteriovenous fistula (AVF) is vital for end-stage renal disease patients. This study aims to evaluate the effects of Fogarty balloon catheter dilation on creating an effectively functioning AVF.
Methods: This retrospective cohort study was conducted at our clinic between 2020 and 2022.

Transjugular intrahepatic portosystemic shunt (TIPS) is a widely used surgery for portal hypertension. In clinical practice, the diameter of the stent forming a shunt is usually selected empirically, which will influence the postoperative portal pressure. Clinical studies found that inappropriate portal pressure after TIPS is responsible for poor prognosis; however, there is no scheme to predict postoperative portal pressure.

Purpose: To compare costs of intravascular ultrasound (IVUS)-guided transjugular intrahepatic portosystemic shunt (TIPS) creation versus non-IVUS-guided TIPS creation, accounting for differences in procedure time and resource utilization.
Materials And Methods: This single institution retrospective study estimated procedure time and resource utilization from 157 consecutive elective TIPS creation procedures, of which 91 were IVUS-guided and 66 were non-IVUS-guided. Differences in procedure costs were derived using time-driven activity-based costing.

Background And Purpose: Proximal protection devices, such as TransCarotid Artery Revascularization (TCAR, SilkRoad Medical, Sunnyvale), aim to yield better outcomes in carotid artery stenting (CAS) than distal protection devices by preventing plaque embolization to the brain. However, transfemoral catheters may not fully reverse flow from the external carotid artery (ECA) to the internal carotid artery (ICA). We assess a new balloon-sheath device, Femoral Flow Reversal Access for Carotid Artery Stenting (FFRACAS), for this purpose.

Peripheral arterial chemoreceptors monitor the levels of arterial blood gases and adjust ventilation and perfusion to meet metabolic demands. These chemoreceptors are present in all vertebrates studied to date but have not been described fully in reptiles other than turtles. The goals of this study were to 1) identify functional chemosensory areas in the South American rattlesnake (Crotalus durissus) 2) determine the neurochemical content of putative chemosensory cells in these areas and 3) determine the role each area plays in ventilatory and cardiovascular control.
