Preoperative Thoracic CT Findings Associated With Postoperative Mechanical Ventilation in Patients Undergoing Major Abdominal or Pelvic Surgery: A Matched Case-Control Study.

. Postoperative prolonged mechanical ventilation is associated with increased morbidity and mortality. Reliable predictors of the need for postoperative mechanical ventilation after abdominal or pelvic surgeries are lacking.

Packed red blood cell transfusion associates with acute kidney injury after transcatheter aortic valve replacement.

Background: Acute kidney injury after cardiac surgery significantly associates with morbidity and mortality. Despite not requiring cardiopulmonary bypass, transcatheter aortic valve replacement patients have an incidence of post-procedural acute kidney injury similar to patients who undergo open surgical aortic valve replacement. Packed red blood cell transfusion has been associated with morbidity and mortality after cardiac surgery.

Atherosclerosis on CT Angiogram Predicts Acute Kidney Injury After Transcatheter Aortic Valve Replacement.

Objective: The purpose of this study is to determine the association of vascular calcification and renal artery stenosis on CT angiogram (CTA) obtained before transcatheter aortic valve replacement (TAVR) with postprocedure acute kidney injury (AKI).

Materials And Methods: In this single-center retrospective cohort study, 106 pre-TAVR CTAs were evaluated by two independent blinded readers. Renal artery stenosis was visually graded as less than 50% or greater than or equal to 50% luminal narrowing.
