Article Synopsis
  • Renal artery stenosis (RAS) is a condition where the renal artery is narrowed by 60% or more, most commonly due to atherosclerotic plaques, affecting 5-10% of the population; rare causes include fibromuscular dysplasia and vasculitis.
  • The standard diagnostic method for RAS is digital subtraction angiography (DSA), but other imaging techniques like Doppler ultrasonography and CT angiography are also important.
  • Treatment typically involves percutaneous transluminal angioplasty (PTA), and a case study highlights a 19-year-old patient who benefitted from using a paclitaxel-coated balloon to restore renal artery function and reduce hypertension.

Article Synopsis
  • Renal artery stenosis (RAS) and mid-aortic syndrome (MAS) are important but often overlooked causes of high blood pressure in children, with RAS involving the narrowing of renal arteries and MAS affecting the abdominal aorta and associated vessels.
  • These conditions can arise from genetic issues and other factors like fibromuscular dysplasia and Takayasu arteritis, making their symptoms complicated and hard to diagnose despite improved imaging techniques.
  • Treatment varies from medications that only partially control blood pressure to more invasive options like angioplasty and surgery, and the article emphasizes the need for a multidisciplinary approach and early detection to improve treatment outcomes for affected children.

Peripheral arterial disease (PAD) represents one of the most prevalent cardiovascular disease processes and carries a high burden of morbidity and mortality. Patients with chronic limb-threatening ischemia (CLTI), the most severe manifestation of PAD, have the highest rates of cardiovascular morbidity and mortality of the overall PAD population. Patients with below-the-knee (BTK) PAD have an increased propensity toward CLTI due to small-vessel caliber and the frequently comorbid conditions of end-stage renal disease and diabetes mellitus, which tend to affect small artery beds preferentially.
