Abstract
The Indigo system (Penumbra Inc., Alameda, CA, USA), a new thrombus aspiration device for acute lower limb ischemia and acute superior mesenteric artery occlusion, was first covered by health insurance in Japan on September 1st, 2023. Until now, thrombolytic therapy has been widely performed for these acute arterial occlusive diseases, but, it has become difficult due to the suspension of the supply of urokinase preparations. The Indigo system promotes active thrombectomy using a vacuum pump that generates substantial suction and is expected to be a promising alternative treatment in the current circumstances. This article introduces the basics of the Indigo system and how to use it by presenting clinical cases.
