A 55-year-old woman underwent bilateral renal artery stent placement with good angiographic result. After the procedure, the patient complained of left flank pain secondary to subcapsular hematoma. Retrospective evaluation of images taken during stent implantation favored the diagnosis of guidewire perforation. Three hours after the procedure, contrast-enhanced computed tomography and subsequent renal angiography showed multifocal extravasations. We performed emergent renal ablation for the treatment of massive bleeding. To our knowledge, this is the first use of transcatheter renal ablation technique for this purpose.

Real-world outcomes in cardiac resynchronization therapy patients: Primary results of the SMART registry.
ESC Heart Fail
December 2024
Boston Scientific Corporation, St. Paul, Minnesota, USA.
Article Synopsis
- Cardiac resynchronization therapy (CRT) is effective for treating heart failure but is under-researched in patients with common comorbidities like atrial fibrillation (AF).
- The SMART registry enrolled 2035 patients to assess CRT response based on clinical outcomes over 12 months, focusing on factors like all-cause mortality, hospitalizations, and quality of life.
- Results showed 58.9% of patients improved, but factors like age, AF, and diabetes were linked to lower CRT responsiveness, with patients having AF experiencing higher rates of hospitalizations and mortality compared to those in normal rhythm.
Effect of Transforming Growth Factor-β Inhibition on Ureteral and Renal Scarring in a Rat Model of Upper Urinary Tract Ablation with Irreversible Electroporation.

Objective: To determine whether adjuvant transforming growth factor-β (TGF-β) inhibition with pirfenidone (PFD) can mitigate ureteral wall scarring and related complications in a rat model of upper urinary tract ablation with irreversible electroporation (IRE).
Methods: Transmural ablation of the ureter was performed with IRE in 24 rats. Post-IRE, animals were randomly assigned to receive PFD or no drug, followed by euthanasia at 2-, 5-, or 10-days.
O-GlcNAc transferase promotes vascular smooth muscle calcification through modulating Wnt/β-catenin signaling.

Vascular calcification (VC), associated with high cardiovascular mortality in patients with chronic kidney disease (CKD), involves osteogenic transdifferentiation of vascular smooth muscle cells (VSMCs). O-GlcNAcylation, a dynamic post-translational modification, is closely linked to cardiovascular diseases, including VC. However, the exact role and molecular mechanism of O-GlcNAc signaling in abnormal mineral metabolism-induced VC remain unclear.

In patients with renal masses, when intervention is warranted, partial nephrectomy is preferred when feasible, especially for T1 renal masses. Thermal ablation, however, has become an accepted alternative treatment of small renal neoplasms with excellent oncologic outcomes. The National Comprehensive Cancer Network guidelines include thermal ablation as a treatment strategy for managing T1a and select T1b masses.

We report a case of computed tomography-guided percutaneous radiofrequency ablation of a bleeding renal angiomyolipoma. Radiofrequency ablation was performed as an alternative to partial nephrectomy and super-selective renal artery embolization for ruptured renal angiomyolipoma with slow persistent bleeding in a patient with elevated serum creatinine levels and other comorbidities. Computed tomography-guided radiofrequency ablation successfully stopped the active hemorrhage and did not affect long-term renal function during the 3-year follow period.
