Insights

Endovascular treatment for subclavian artery stenosis and occlusion is safe and effective, showing high success and patency rates. This approach is recommended as a first-line therapy in experienced vascular centers.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Endovascular Interventions

Background:

  • Subclavian artery stenosis and occlusion are prevalent upper extremity arterial diseases, primarily caused by atherosclerosis.
  • Endovascular treatment offers a potential alternative to open surgery, but supporting data remain limited.
  • This study assesses endovascular procedures for subclavian artery lesions at a Vietnamese tertiary vascular center.

Purpose of the Study:

  • To evaluate the safety and effectiveness of endovascular treatment for subclavian artery stenosis and occlusion.
  • To determine the short- and long-term outcomes and patency rates of these procedures.
  • To provide evidence supporting endovascular therapy as a primary treatment option.

Main Methods:

  • Retrospective analysis of patients undergoing endovascular treatment for symptomatic subclavian artery stenosis or occlusion (October 2013 - April 2022).
  • Assessment of clinical characteristics, procedural details, and outcomes.
  • Evaluation of short- and long-term results, including complication rates and patency.

Main Results:

  • Twenty-five patients (mean age 56.8 years) with atherosclerotic risk factors were included.
  • Endovascular procedures achieved 96% technical success with an 8% complication rate.
  • Median follow-up was 43 months, with a 3-year patency rate of 92%.

Conclusions:

  • Endovascular treatment for subclavian artery stenosis/occlusion is safe and effective.
  • Excellent long-term patency rates support percutaneous revascularization as a first-line therapy.
  • Further research with larger cohorts and extended follow-up is warranted.

Aortic Regurgitation III: Medical Management01:25

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
