An 80-year-old man received stent implantation for severe stenosis of the right renal artery. During the procedure, the proximal edge of the stent was successfully positioned at the ostium of the renal artery. After 6 months, follow-up renal angiography showed transverse stent fracture without restenosis. The proximal part of the fractured stent had moved and protruded into the abdominal aorta. Three years later, the proximal part of the fractured stent had migrated from the renal artery to the wall of infrarenal aorta. This is the first reported case of stent migration of the renal artery caused by a complete transverse stent fracture.

Unexpected identification of peak systolic velocity in the radial artery as a risk factor for functional primary patency of radiocephalic fistulas.
Nefrologia (Engl Ed)
January 2025
Department of Ultrasound, The Second Hospital of Dalian Medical University, Dalian City, Liaoning Province, China. Electronic address:
Objective: As radiocephalic fistula is not necessarily appropriate for all patients with advanced kidney disease, our aim was to investigate the sensitive indicators that affect the functional primary patency of radiocephalic fistulas.
Methods: This prospective observational study included consecutive patients referred to the Second Hospital of Dalian Medical University for initial creation of radiocephalic fistula from July 2017 to December 2019. Preoperative ultrasound parameters, demographic characteristics, serum indicators and comorbidities were recorded.
Outcomes of Patients Treated with Double-Wide Scallop vs Fenestrations for Celiac Artery Incorporation During Repair of Complex Abdominal Aortic Aneurysms.

Objectives: Celiac artery (CA) incorporation during FB-EVAR for complex abdominal aortic aneurysms (cAAA) is typically performed with fenestrations. Double-wide scallops (DWS) can be used when appropriate. We aimed to assess outcomes of patients treated with DWS for the CA during FB-EVAR for cAAA.

Cardiology Department (P.B., X.L., V.T.T., M.A.B., A.V., E.Y., D.M.N., U.P., J.L., S.P.T., P.C.Q.), Westmead Hospital, Sydney, Australia.
Background: Transcatheter renal denervation (RDN) remains inconsistent despite developments in ablation technologies, due to the lack of an intraprocedural physiological end point.
Objective: To identify whether aorticorenal ganglion (ARG) guided RDN using microwave (MW) catheter leads to more consistent denervation outcomes compared with empirical MW ablation.
Methods: Pigs underwent sham procedure (n=8) or bilateral RDN using an in-house built open-irrigated MW catheter.

Department of Medical Imaging, Lille Catholic University, Saint-Philibert Hospital, ETHICS laboratory, Lille, EA, France.
Objective: The objective of this study was to explore the ability of dual-energy computed tomography (DECT) to detect monosodium urate (MSU) crystal deposits in the kidneys and renal artery walls, and uric acid urolithiasis, in patients with gout and chronic kidney disease (CKD).
Methods: Patients with gout and with stage 2-4 CKD were prospectively included in this cross-sectional study. Patients underwent renal, knee and feet DECT scans.
