Vascular Spasm01:16

Vascular Spasm

3.1K
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last...

Venous Thrombosis III: Interprofessional Care

222
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...

Area of Science:

  • Neurology
  • Interventional Neurology
  • Stroke Medicine

Background:

  • Mechanical thrombectomy is a key treatment for acute ischemic stroke.
  • Vasospasm is a known, usually transient, periprocedural complication.

Observation:

  • This report details the second documented case of symptomatic delayed vasospasm.
  • The vasospasm was a unique, device-related adverse event following mechanical thrombectomy.

Findings:

  • Delayed vasospasm after mechanical thrombectomy can be symptomatic.
  • Device-related complications can manifest as delayed neurological events.

Implications:

  • Clinicians should be aware of the potential for delayed symptomatic vasospasm.
  • Close patient follow-up is crucial after mechanical thrombectomy to detect such adverse events.
