Observational StudyRenal resistive index assessment by intraoperative transesophageal echocardiography is associated with acute kidney injury after cardiac surgery: a prospective observational study.
Acute kidney injury (AKI) is a major health burden after cardiac surgery. Renal vasoconstriction and venous congestion can be assessed via transesophageal echocardiography (TEE). The primary objective is to determine feasibility of measuring intraoperative Renal resistive index (RRI) and portal vein pulsatility fraction (PF) by TEE. The secondary objectives are to determine the association between RRI and/or PF and postoperative AKI, Intensive Care Unit (ICU) length of stay, hospital length of stay, and 30-day mortality. ⋯ This study demonstrates high feasibility for obtaining intraoperative TEE measurement of RRI and PF and significant correlation between postoperative AKI with pre CPB RRI, post chest closure RRI, and the combination of RRI at the three timepoints.

Ventriculo-peritoneal shunt procedures can improve idiopathic normal pressure hydrocephalus (iNPH) symptoms. However, there are no automated methods that quantify the presurgery and postsurgery changes in the ventricular volume for computed tomography scans. Hence, the main goal of this research was to quantify longitudinal changes in the ventricular volume and its correlation with clinical improvement in iNPH symptoms. Furthermore, our objective was to develop an end-to-end graphical interface where surgeons can directly drag-drop a brain scan for quantified analysis. ⋯ Proposed metric quantifies changes in ventricular volume before and after shunt surgery for patients with iNPH, serving as an automated and effective radiographic marker for a functioning shunt in a patient with iNPH.

Abdominal aortic aneurysm (AAA) is a significant global health concern, yet comprehensive population-based studies remain limited. This study aimed to evaluate the hospitalization rates, surgical trends, mortality, and reintervention rates for ruptured (r-AAA) and nonruptured (nr-AAA) AAA using data from a national health insurance database. ⋯ AAA predominantly affects older individuals, and the annual incidence shows a declining trend. Since the introduction of EVAR, its use has steadily increased while OSR rates have decreased. Although both EVAR and OSR are associated with reduced mortality in patients with r-AAA, OSR is linked to superior long-term survival outcomes.
