Purpose: We aimed to present our clinical experience with the renal artery catheterization (RAC) technique, which reduces the volume of intra-arterial contrast media (ICM) used during endovascular aortic repair (EVAR), and describe the short-term results of this technique.
Materials And Methods: We retrospectively evaluated 16 patients (15 males and one female) who underwent EVAR between March 2011 and February 2012 using the RAC technique for an abdominal aortic aneurysm. A Simmons-1 catheter was preferred for renal artery cannulation. The mean age of the patients at the time of treatment was 70 years (range, 61-82 years). Fifteen cases were fusiform aneurysms, and one case was a saccular aneurysm. Creatinine and estimated glomerular filtration rate (eGFR) values were recorded before the procedure and during the first 72 hours postprocedure.
Results: Bifurcated stent grafts were implanted with 100% procedural success using the RAC technique. The inferiorly positioned renal artery was cannulated with a Simmons-1 catheter in the first five patients, and was maintained at the level of the renal artery orifice in the remaining patients. The mean volume of the ICM used was 47 mL (range, 23-83 mL). The creatinine and eGFR values were not significantly different between the pre- and postoperative periods (P > 0.05).
Conclusion: Reducing the volume of ICM used during EVAR is critical for protecting renal function. The RAC technique is a safe and effective method in appropriate patients when performed by experienced clinicians.
Background: Hypertension is a risk factor for bleeding events and is included in the HAS-BLED (Hypertension, Abnormal renal/liver function, Stroke, Bleeding history or predisposition, Labile INR, Elderly, Drugs/Alcohol concomitantly)score. However, the effects of blood pressure (BP) and changes in BP on bleeding events in patients undergoing percutaneous coronary intervention (PCI) remain poorly understood. This study is aimed to investigate the relationship between systolic BP (SBP) changes during hospitalisation and bleeding events in patients undergoing PCI.
We report a case of a very rare association of adrenal adenoma, unilateral adrenal hyperplasia, and bilateral renal artery stenosis. A 61-year-old man with a remarkable history of two severe strokes was admitted to the Nephrology department with hypertension associated with severe hypokalemia and metabolic alkalosis. Doppler of renal arteries was not conclusive, so contrast-enhanced scanning was done revealing a left adrenal adenoma, right adrenal hyperplasia, and bilateral moderate renal artery stenosis.
Background: Type 1 diabetes (T1D) carries a significant risk of atherosclerosis as the main driver for cardiovascular events. Atherosclerosis is initiated by the activation of the endothelium by various risk factors through the inflammation process. The anti-inflammatory cytokine TGF-β1 may inhibit the development of atherosclerosis.
Traumatic Renal Artery Thrombosis (TRAT) is an uncommon condition characterized by a low clinical incidence and a lack of specific symptoms, making it highly susceptible to being overlooked or misdiagnosed. This retrospective analysis aims to review the diagnostic and therapeutic approaches applied to a TRAT patient who received successful treatment in the Emergency Medicine Department of the First People's Hospital of Kunshan. The objective is to enhance clinicians' comprehension of TRAT, promote early diagnosis and intervention, and ultimately improve patient outcomes.
Kidney tissue injury in renal artery stenosis (RAS) involves inflammation, endoplasmic reticulum stress (ERS), and mitochondria damage. Tumor necrosis factor-stimulated gene-6 (TSG-6), an endogenous reparative molecule, may decrease ERS and improve renal function. To assess its impact on the stenotic murine kidney, we injected TSG-6 or vehicle for two weeks in mice with RAS.
