Mid-term Outcomes of Image-Guided Surgical Thromboembolectomy and Routine Intraoperative Angiography for Native Vessel Acute Lower-Limb-Threatening Ischemia.

Background: Standard balloon-catheter thromboembolectomy (TE) is an established effective treatment for acute lower-limb ischemia (ALI) with recognized limitations when there is an underlying arterial lesion or thromboembolism of the infrapopliteal arteries. The aim of this study was to evaluate the efficacy and safety of image-guided surgical TE combined with routine intraoperative completion angiography in the treatment of ALI patients.

Methods: Between September 2020 and August 2022, this prospective study included all consecutive adult patients presenting to a tertiary center with unilateral ALI of Rutherford class II due to thromboembolic occlusion of native arteries who underwent image-guided surgical TE and routine completion intraoperative angiography.
