Novel Application of Large Bore Aspiration in the Treatment of COVID-19 Associated Acute Limb Ischemia Using the Penumbra CAT 12 Lightning Aspiration System.

COVID-19 associated cardiovascular complications have been well documented throughout the pandemic and are associated with higher rates of morbidity and mortality. Hypercoagulable states resulting from systemic inflammation have been associated with increasing incidences of acute myocardial infarctions (AMI) and acute limb ischemia (ALI). Herein, we present a case of AMI complicated by ALI in a patient with COVID-19 in which aspiration thrombectomy using the Penumbra CAT 12 thrombectomy catheter was used in the management of acute popliteal artery occlusion.

Novel Use of the Penumbra CAT 12 Lightning Aspiration System for the Treatment of a Complex Thrombus.

Debulking procedures using aspiration devices have been previously described in the literature to treat vegetations or thrombi on intracardiac structures such as the tricuspid valve. Transcatheter therapy has also been shown to be an effective alternative to surgical treatment for managing high risk or non-surgical patients. Furthermore, aspiration procedures can help identify the unique etiologies of intracardiac masses which can greatly impact differing treatment modalities. Utilization of aspiration devices combined with blood-loss limiting technologies have led to an increased interest in using aspiration systems to address a wider array of clinical situations that can occur. Herein we describe our experience in using the Penumbra CAT 12 Lightning Aspiration System in addressing and treating a mobile mass attached to the lead of an implantable cardiac device.
