[Thrombolytic agents in cerebral infarctions].

Summary

Thrombolytic therapy can restore arterial patency to reduce cerebral infarction. Selective intra-arterial thrombolysis shows promise, particularly in carotid artery occlusions, and may be beneficial for basilar artery occlusions.

Area of Science:

  • Neurology
  • Vascular Medicine
  • Interventional Radiology

Context:

  • Cerebral infarction, caused by arterial occlusion, poses significant morbidity and mortality risks.
  • Thrombolytic agents aim to restore blood flow and prevent ischemic damage.
  • Evaluating the efficacy and safety of different thrombolysis approaches is crucial for stroke management.

Purpose:

  • To review and compare the outcomes of systemic and selective intra-arterial thrombolysis for cerebral infarction.
  • To assess the influence of occlusion site (carotid vs. vertebrobasilar) on thrombolysis effectiveness.
  • To determine the risk of cerebral hemorrhage associated with thrombolytic therapy.

Summary:

  • Systemic thrombolysis showed a 22.2% mortality rate and 58.2% satisfactory outcome. Selective intra-arterial thrombolysis had a 29.7% mortality rate and 84.5% satisfactory outcome.
  • Outcomes varied by occlusion site: carotid system (10.4% mortality, 84.4% outcome) and vertebrobasilar system (61.5% mortality, 85.0% outcome).
  • Selective intra-arterial thrombolysis is likely justified for carotid occlusions and potentially beneficial for basilar artery occlusions, with an estimated 14% mortality for the latter.

Impact:

  • Selective intra-arterial thrombolysis appears more effective than systemic thrombolysis, especially for carotid occlusions.
  • The findings suggest potential indications for selective intra-arterial thrombolysis in basilar artery occlusions, despite associated risks.
  • Further research is needed, considering factors like occlusion site, for optimal thrombolytic treatment strategies in stroke.
