Directional Femoral Ultrasound-Guided Compression Technique Using in Percutaneous Mechanical Thrombectomy for Acute Deep Vein Thrombosis: A Retrospective Cohort Study.

Residual thrombus in common femoral vein is a difficult problem associated with higher incidence of PTS. Few studies have focused on common femoral venous thrombus clearance. PMT with directional femoral UCT could improve the thrombus clearance rate and primary patency rate of acute iliofemoral DVT, and might decrease the incidence of PTS compared to traditional PMT treatment without UCT. Directional femoral UCT is recommended in PMT treatment of acute iliofemoral DVT.
