Pharmaco-mechanical thrombectomy for early thrombus removal.

Area of Science:

• Vascular Medicine
• Interventional Cardiology
• Thrombosis Research

Background:

• Venous thromboembolism (VTE) poses a significant health burden.
• Early thrombus removal is crucial to prevent valvular damage and post-thrombotic syndrome (PTS).
• Current literature on pharmaco-mechanical thrombectomy (PMT) outcomes needs comprehensive review.

Purpose of the Study:

• To review the current literature on the outcomes of pharmaco-mechanical thrombectomy (PMT) for early thrombus removal in patients with venous thromboembolism (VTE).
• To compare PMT outcomes with catheter-directed thrombolysis (CDT).

Main Methods:

• MEDLINE database search and manual reference review.
• Inclusion of studies reporting outcomes of PMT alone and PMT versus CDT.
• Outcomes assessed: clot lysis, pulmonary embolism (PE), major bleeding, recurrent deep vein thrombosis (DVT), venograms, and lytic agent volume.

Main Results:

• Nine articles reported on PMT using devices like Angiojet, Trellis, and Helix with various thrombolytics.
• Complete and partial thrombus removal rates were up to 84% and 64% for PMT, and 81% and 59% for CDT.
• PMT significantly reduced procedure duration, lytic use, and the number of venograms compared to CDT.
• Data on PE and bleeding risks comparing PMT and CDT remain limited.

Conclusions:

• Pharmaco-mechanical thrombectomy (PMT) is a feasible, safe, and efficient alternative for expediting thrombolysis in VTE.
• Early thrombus removal aims to mitigate valvular damage and reduce the risk of PTS.
• Further research is needed to fully elucidate PE and bleeding risks associated with PMT.
