Insights

Intracranial angioplasty with coronary stents shows promise for stenosis treatment. However, a case of basilar artery stenosis demonstrated rapid re-stenosis and vessel rupture during stent-assisted angioplasty, highlighting potential complications.

Area of Science:

  • Neurology
  • Interventional Cardiology
  • Vascular Surgery

Background:

  • Intracranial artery stenosis poses a significant risk for stroke.
  • Stent-assisted angioplasty is increasingly used for intracranial stenosis.
  • Complications and long-term outcomes require further investigation.

Purpose of the Study:

  • To report a rare case of basilar artery stenosis.
  • To investigate the complications of stent-assisted angioplasty in this context.
  • To analyze pathological findings following a procedure failure.

Main Methods:

  • A case of basilar artery stenosis was treated with balloon angioplasty.
  • The patient experienced rapid re-stenosis and underwent stent-assisted angioplasty.
  • Autopsy was performed to examine the vessel pathology.

Main Results:

  • Simple balloon angioplasty led to rapid re-stenosis.
  • Stent-assisted angioplasty resulted in vessel rupture.
  • Autopsy revealed vessel wall disruption and elastic lamina defects at the stent site.

Conclusions:

  • While stent-assisted angioplasty is a viable option for intracranial stenosis, this case highlights potential severe complications.
  • Rapid re-stenosis and vessel rupture can occur, necessitating careful patient selection and procedural monitoring.
  • Pathological findings underscore the importance of understanding vessel wall response to stenting in the intracranial circulation.

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...

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...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
