ABSTRACT
Acute limb ischemia (ALI) due to arterial thromboembolic occlusion is a critical emergency in vascular medicine, requiring attention for rapid diagnosis and intervention, to prevent limb loss and major amputation, which is associated with patient disability in the long term. Traditionally, surgical embolectomy has been used for the treatment of ALI. Endovascular treatment of ALI traditionally involved catheter-directed thrombolysis. This option, however, poses some limitations, including an increased risk for access site and systemic bleeding complications, especially in patients with high bleeding risk. Therefore, in the last decades, several devices have been developed and tested for the mechanical endovascular treatment of ALI. Such devices involve either rotational thrombectomy or continuous thrombus aspiration. While rotational thrombectomy is limited in rather large arteries due to the risk of dissection and perforation in arteries <3 mm, continuous thrombus aspiration can be applied in smaller vessels and tortuous anatomies. In our case series we present a minimal-invasive endovascular approach for the treatment of two patients with ALI due to thrombotic occlusion of tortious and small diameter arteries. Minimal-invasive mechanical thrombectomy using the Penumbra Aspiration System emerged as a successful alternative to surgical embolectomy, enabling prompt treatment and with a short hospital stay for both patients. Our article therefore highlights the use of continuous thrombus aspiration in small diameter vessels and tortuous anatomies, which may represent a contraindication for the use of rotational thrombectomy. In addition, this technique may be applied even in patients with higher bleeding risk since additional lysis is not necessary in patients, where complete thrombus removal can be achieved by this device.
