Insights

Symptomatic intracranial atherosclerotic disease (ICAD) causes 10% of US ischemic strokes. This review examines angioplasty and stenting for critical ICAD stenosis refractory to medical management.

Area of Science:

  • Neurology
  • Vascular Surgery
  • Interventional Radiology

Background:

  • Symptomatic intracranial atherosclerotic disease (ICAD) accounts for 10% of ischemic strokes in the US.
  • High-grade stenosis (>70%) in ICAD carries a significant risk of recurrent stroke (up to 35%).
  • Optimizing medical and endovascular treatments for ICAD is a key focus in stroke research.

Purpose of the Study:

  • To review the current state of endovascular treatment for symptomatic ICAD.
  • To evaluate the safety, suitability, and efficacy of angioplasty and/or stenting for critical ICAD stenoses.
  • To address the therapeutic strategy for patients with ICAD refractory to medical management.

Main Methods:

  • Comprehensive literature review of symptomatic ICAD studies.
  • Analysis of existing data on angioplasty and/or stenting in severe symptomatic ICAD.
  • Focus on case series and the need for randomized trial results.

Main Results:

  • Current data predominantly consists of case series for endovascular interventions in ICAD.
  • Randomized trial results comparing endovascular therapy to medical treatment are pending.
  • The efficacy and safety of angioplasty/stenting in refractory ICAD require further robust evidence.

Conclusions:

  • Angioplasty and/or stenting are potential therapeutic options for symptomatic ICAD.
  • Further randomized controlled trials are needed to establish definitive evidence for endovascular treatment efficacy in ICAD.
  • Optimizing treatment strategies for ICAD remains crucial for stroke prevention.

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

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...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
