Catheter Expands Treatment Options
The current study, a subgroup analysis of the RESCUE trial, was one of the first to examine the impact of catheter-directed lysis on distal occlusions, study coauthor Parth M. Rali, MD, said in an interview.
To this point, literature has been limited to evaluation for proximal disease, said Dr. Rali, director of thoracic surgery and medicine and part of the Pulmonary Embolism Response Team at Temple University Hospital, Philadelphia.
Dr. Rali said he was encouraged to see confirmation that the BEC catheter, because of its design, works in patients with proximal or distal occlusive disease.
In clinical practice, “the catheter provides an additional option for care in patients with multiple distal occlusive disease when a systemic tissue plasminogen activator (tPA), may put patient at high bleeding risk,” Dr. Rali said.
Looking ahead, a prospective, observational multicenter study would be useful to validate the findings from the post hoc analysis of the current study, he noted.
The study was sponsored by the National Heart, Lung, and Blood Institute, Commonwealth of Pennsylvania, and Thrombolex Inc., a medical device company developing interventional catheter-based therapies for the rapid and effective treatment of acute venous thromboembolic disorders. Dr. Bashir is a cofounder and has an equity interest in Thrombolex Inc. Dr. Rali disclosed serving as a consultant for Thrombolex, Inari Medical, Viz AI, and ThinkSono.
