Renovascular Disease and Mesenteric Vascular Disease

Area of Science:

• Vascular Medicine
• Nephrology
• Cardiology

Background:

• Renal artery stenosis (RAS) arises from atherosclerosis and fibromuscular dysplasia, leading to ischemic nephropathy, renovascular hypertension, and cardiovascular disease.
• Mesenteric ischemia, acute or chronic, results from arterial embolism/thrombosis, venous thrombosis, or nonocclusive events.
• These conditions significantly impact patient morbidity and mortality.

Purpose of the Study:

• To review the epidemiology, pathophysiology, diagnosis, and management of renal artery stenosis and mesenteric ischemia.
• To delineate the clinical scenarios warranting screening for RAS.
• To summarize current understanding and treatment strategies for both vascular conditions.

Main Methods:

• Literature review of epidemiological data.
• Pathophysiological mechanisms of RAS and mesenteric ischemia.
• Analysis of diagnostic modalities and therapeutic interventions.

Main Results:

• RAS screening is not routine but indicated for specific hypertension and renal insufficiency presentations.
• Acute mesenteric ischemia often involves embolism/thrombosis; chronic forms typically result from arterial obstruction.
• Early diagnosis and intervention are crucial for favorable outcomes in both conditions.

Conclusions:

• Renal artery stenosis and mesenteric ischemia are serious vascular diseases requiring careful evaluation.
• Risk stratification and targeted screening are essential for RAS.
• Comprehensive management strategies are necessary for optimizing outcomes in mesenteric ischemia.
