Fibromuscular dysplasia (FMD) is a rare nonatherosclerotic, noninflammatory vascular disease affecting mostly renal and carotid arteries and is the second most frequent cause of renal artery stenosis. The symptomatology is dominated by arterial hypertension due to the frequent involvement of the renal arteries and depends on the location of the lesions. Most of the cases are middle-aged women of Caucasian origin. There are two subtypes based on angiographic aspect: multifocal FMD (80% of the cases) and focal FMD (rarer with a more balanced sex ratio). Angioplasty of the renal arteries is generally disappointing with less than 50% cure of hypertension. It appears necessary to improve our knowledge of the FMD and to optimize the selection of eligible patients for revascularization with transdisciplinary collegial therapeutic decision.

Approximately 5-10% of patients with hypertension have secondary hypertension. We describe a case of secondary hypertension from bilateral renal artery stenosis (RAS): "Pickering syndrome." This is a case of hypertension secondary to bilateral RAS which provides an opportunity to review secondary hypertension with a specific focus on RAS, in terms of when to consider work up, causes of secondary hypertension, diagnostic testing, and treatment.

Background And Aim: Coronary artery bypass grafting (CABG) is a key treatment for coronary artery disease, but accurately predicting patient survival after the procedure presents significant challenges. This study aimed to systematically review articles using machine learning techniques to predict patient survival rates and identify factors affecting these rates after CABG surgery.

Percutaneous vertebroplasty (PVP) is a widely utilized minimally invasive technique originally developed for the treatment of vertebral compression fractures. It has since expanded to treat osteoporotic vertebral compression fractures, pathologic vertebral fractures resulting from primary or secondary spinal tumors, and traumatic spinal fractures. Despite its benefits, PVP is associated with significant complications, the most common of which is bone cement leakage.

The increasing age of patients with end-stage renal disease raises the issue of hostile arterial access for transplantation, with technical difficulties associated with clamping and suturing the iliac artery. Some of these patients - who theoretically represent those who would benefit the most from transplantation in terms of mortality - are contraindicated because of anatomical and medical issues. In this context, a specific endovascular device called EndoPreKiT (Endovascular Preparation for Kidney Transplantation) has been designed, enabling arterial access for transplantation via a mini-invasive procedure.
