Conventional anticoagulation for acute DVT can cause post-thrombotic syndrome (PTS). Therefore, early thrombus removal strategies for acute DVT are widely appreciated across different societies. PMT is recently-established therapy to manage acute DVT when experts and resources are available. In Korea, CDAT is popular options for acute DVT because PMT devices are limited by reimbursement issues. We compared the results of PMT with Angiojet with CDAT and evaluated risk factors affecting patients’ outcome.
This is a retrospective study from a prospectively registered database of the patients, who underwent interventional procedures due to acute DVT in Seoul St. Mary’s Hospital from 2013 to 2015. PMT with AngioJet and Solent Omni catheter was compared to CDAT for acute DVT. Patients' demographics, procedural information, their results, and complications were retrieved from EMR and PACS and analyzed with SPSS 10.1.
Fifty-eight patients were enrolled. 22 patients were treated by PMT, and 36 by CDAT. There was no procedure or in-hospital mortality in both groups. There were 3 additional thrombolysis in PMT group and 6 in CDAT group. There was no difference of technical success rate between PMT and DCAT regardless of thrombolysis (P=0.4183, P=9.205). The limitation of PMT with Angiojet was a short operating time of AngioJet (less than 5 mins) with residual thrombus while large thrombus embolization in DCAT.
PMT with AngioJet and DCAT are a safe and effective strategy for early thrombus removal of patients with acute DVT with different pitfalls. This study is limited by the small number and retrospective study.
