Insights

Angioplasty and stenting of vertebral artery (VA) stenosis is feasible and safe for extracranial cases. Intracranial VA stenosis procedures are possible but carry life-threatening risks, requiring further study.

Area of Science:

  • Vascular Surgery
  • Interventional Neuroradiology
  • Cardiovascular Medicine

Background:

  • Vertebral artery (VA) stenosis poses a risk of stroke.
  • Treatment options for VA stenosis include angioplasty and stenting.

Purpose of the Study:

  • To evaluate the feasibility and safety of angioplasty or angioplasty and stenting for extra- and intracranial vertebral artery stenosis.

Main Methods:

  • 16 patients with 16 stenotic VAs underwent angioplasty or angioplasty with stenting.
  • Stenoses were located in V1, V2, and V4 segments; 14 were symptomatic and atherosclerotic.

Main Results:

  • Procedures were technically successful in 14 of 16 VAs (87%).
  • Complications included asymptomatic vessel dissection and one fatal subarachnoid hemorrhage due to vessel perforation.

Conclusions:

  • Extracranial VA stenosis treatment with angioplasty/stenting shows high success and low complication rates.
  • Intracranial VA stenosis procedures are feasible but associated with potentially life-threatening complications.
  • Future research should focus on durability and complication rates of primary stenting without predilation.

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 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...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
Anastomoses01:19

Anastomoses

In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.
Arterial Anastomosis: These occur between arteries. They are most common in...
