Intra-Arterial Thrombolysis

Intra-arterial thrombolysis offers benefit in cases with persisten obstruction (despite intra-venous thrombolysis - approximately 32-60%), patients arriving beyond the 3 hour time window for IV therapy. It also reduces hemorrhagic complications while allowing for precise imaging of anatomy, pathology and collateral pattern in the brain tissue.

Recent clinical trials have shown efficacy of almost 76% with IA Thrombolysis in stroke patients. Under this technique a catheter is advanced to the site of the block under radiological visual control, and the clot busting drugs are introduced at the site of the block, offering high concentration of the required medicine at the site of the blockage.
