Recent advances in intra-arterial thrombolysis

Area of Science:

• Neurology
• Vascular Medicine
• Interventional Cardiology

Background:

• Intravenous thrombolysis is a cornerstone treatment for acute ischemic stroke (AIS).
• Limitations of IV thrombolysis include a narrow therapeutic window, poor targeting of occlusions, and suboptimal recanalization.
• Intra-arterial (IA) thrombolysis presents a potential solution to these challenges.

Purpose of the Study:

• To review thrombolytic agents used in AIS.
• To compare the rationale and efficacy of IA versus IV thrombolysis.
• To discuss clinical trials and alternative endovascular techniques for IA thrombolysis.

Main Methods:

• Review of existing literature on thrombolytic agents and their mechanisms.
• Analysis of clinical trial data for IA thrombolysis.
• Discussion of mechanical and endovascular approaches.

Main Results:

• IA thrombolysis may circumvent limitations of IV therapy.
• Various thrombolytic agents, dosages, and mechanisms are discussed.
• Clinical trials and endovascular techniques are reviewed.

Conclusions:

• IA thrombolysis offers a promising alternative for AIS treatment.
• Further research and clinical trials are needed to optimize IA therapy.
• Mechanical and endovascular adjuncts may enhance IA thrombolysis outcomes.
