Purpose: To demonstrate the different patterns of renal infarction to avoid pitfalls. To present 'flip-flop enhancement' pattern in renal infarction.
Materials And Methods: Retrospective review of a total of 41 renal infarction in 37 patients were done. These patients underwent initial CT and the diagnosis of renal infarction was confirmed with either follow up CT or at surgery.
Results: Twenty-three patients had wedge-shaped focal infarcts, nine patients had global and five patients had multifocal infarcts of the kidneys. Cortical rim sign was seen predominantly with global infarcts. In five patients, a 'flip-flop enhancement' pattern was observed. In two patients, planned renal biopsies due to tumefactive renal lesions were cancelled because of 'flip-flop enhancement' pattern on follow up CTs.
Conclusion: Although most of our cases were straightforward for the diagnosis of renal infarction, cases with tumefactive lesions and global infarctions without the well-known cortical rim sign were particularly challenging. We describe a new sign, flip-flop enhancement pattern, which we believe solidified the diagnosis of renal infarction in five of our cases. The authors recommend further investigations for association of flip-flop enhancement and renal infarction.

Predictive Value of Preoperative Hypersensitive C-Reactive Protein in the Incidence of Postoperative Cognitive Impairment in Valvular Disease Patients: A Retrospective Study.

Article Synopsis
- Postoperative cognitive dysfunction (POCD) is a complication linked to negative outcomes after cardiac surgery, and this study examines preoperative hypersensitive C-reactive protein (Hs-CRP) as a potential predictor of POCD in patients with valvular heart disease (VHD).
- Analyzing data from 372 VHD patients, the study found a 27.6% incidence of POCD one month post-surgery, with significant differences in age, education level, Hs-CRP levels, and duration of mechanical ventilation between patients who developed POCD and those who did not.
- The findings suggest that elevated preoperative Hs-CRP levels are an independent risk factor for POCD,
A Case Study of Aberrant Aortic Origin of the Right Coronary Artery.

This case report examines a rare cardiovascular abnormality, the Aberrant Aortic Origin of the Right Coronary Artery (AAORCA), in a 75-year-old patient with a history of myocardial infarction, acute renal injury, and cardiogenic shock. Rapid medical intervention, including coronary angioplasty, demonstrated the significance of prompt care. Chronic issues, including tobacco use and left ventricular dysfunction, complicated matters, emphasizing the importance of comprehensive long- term therapy.

Background: There is little research on cardiorenal anemia syndrome (CRAS) in China. This study was to describe the characteristics of patients with CRAS and to explore risk factors of all-cause death.
Methods: A total of 81,795 patients were hospitalized from August 2012 to August 2021 in the nephrology department and cardiology department, of which 820 patients with CRAS were recruited into this study.
We report a case in which mechanical thrombectomy (MT) was performed on a patient with cerebral infarction and renal failure, and contrast leakage remained on postoperative head computed tomography (CT) scans for more than 24 hours. A 75-year-old woman with a medical history of chronic renal failure due to diabetic nephropathy was admitted to the cardiology department of our hospital with chronic heart failure. During hospitalization, her diabetic nephropathy worsened.

Acute heart failure is associated with high hospitalization and mortality rates. A strong, independent risk factor for mortality in patients with heart failure is acute kidney injury, and the condition caused by this connection between disturbances in heart function and proper kidney functioning is cardiorenal syndrome (CRS). This case report discusses the role of continuous renal replacement therapy (CRRT) in the management of a CRS case with septic shock due to pneumonia.
