Summary

Essential thrombocythemia caused intracranial thrombosis and internal carotid artery stenosis. Prompt anticoagulation during acute ischemic stroke prevented vessel obstruction, followed by antiplatelet therapy after platelet count normalization.

Area of Science:

  • Neurology
  • Hematology

Background:

  • Intracranial thrombosis can lead to severe neurological deficits.
  • High-grade internal carotid artery stenosis is a significant risk factor for stroke.

Purpose of the Study:

  • To present a case of stroke secondary to intracranial thrombosis caused by essential thrombocythemia.
  • To highlight the management strategy for acute cerebral ischemia in this context.

Main Methods:

  • Case report detailing a patient with progressive stroke.
  • Diagnosis of intracranial thrombosis and internal carotid artery stenosis.
  • Identification of essential thrombocythemia as the underlying cause.
  • Management with anticoagulation and subsequent antiplatelet therapy.

Main Results:

  • Effective anticoagulation in the acute phase prevented further thrombus progression.
  • Clinical improvement and normalization of platelet counts were achieved with hydroxyurea.
  • Successful transition from anticoagulation to antiplatelet agents.

Conclusions:

  • Essential thrombocythemia is a critical consideration in cryptogenic stroke with thrombosis.
  • Timely anticoagulation is vital in managing acute ischemic stroke due to thrombocythemia.
  • A multi-step antithrombotic strategy can be effective in preventing recurrent events.
