AI Article Synopsis
Article Abstract
Fibromuscular dysplasia is a noninflammatory segmental disease of the arteries, of unknown origin. While the renal arteries are most commonly affected, other larger vessels, including the carotid and vertebrals, may be involved. Fibromuscular dysplasia has been implicated as a cause of stroke in adults and (on rare occasions) in children. The classic angiographic presentation is that of a string of beads. The condition frequently requires surgical or interventional radiological treatment. These approaches most commonly lead to long-term neurological improvement. Five cases with typical angiographic appearance are presented.

Fibromuscular dysplasia (FMD) is a rare, non-atherosclerotic vascular disease affecting medium to large arteries, especially the renal and internal carotid arteries (ICAs). The string-of-beads appearance, indicative of alternating areas of stenosis and dilatation, is a key imaging feature typically observed in the distal ICAs. Diagnosing FMD in critically ill patients poses challenges due to the risks associated with traditional imaging methods such as computed tomography angiography (CTA), magnetic resonance angiography, and digital subtraction angiography.

Treatment-resistant hypertension (TRH) is defined by consistently elevated blood pressure readings unresponsive to medical management. In clinical practice, it poses a significant challenge due to the intertwining variables that may cause the issue to persist such as lifestyle, genetics, and other comorbidities, as opposed to simple medication non-adherence. This report describes the case of a 68-year-old female patient presenting for a routine follow-up with persistently elevated ambulatory blood pressure readings.

Arterial hypertension in young adults, which includes patients between 19 and 40 years of age, has been increasing in recent years and is associated with a significantly higher risk of target organ damage and short-term mortality. It has been reported that up to 10% of these cases are due to a potentially reversible secondary cause, mainly of endocrine (primary aldosteronism, Cushing's syndrome, and pheochromocytoma/paraganglioma), renal (renovascular hypertension due to fibromuscular dysplasia and renal parenchymal disease), or cardiac (coarctation of the aorta) origin. It is recommended to rule out a secondary cause of high blood pressure (BP) in those patients with early onset of grade 2 or 3 hypertension, acute worsening of previously controlled hypertension, resistant hypertension, hypertensive emergency, severe target organ damage disproportionate to the grade of hypertension, or in the face of clinical or biochemical characteristics suggestive of a secondary cause of hypertension.
