Complete Revascularization of Acute Limb Ischemia With Distal Pedal Access

Abstract

Acute limb ischemia (ALI) is an abrupt decrease of blood flow to a limb, resulting in a potential threat to that body part. In ALI, which is commonly caused by embolism or traumatic occlusion, symptoms appear quickly due to a lack of collateral blood flow and extension of the thrombus to arterial outflow. In cases with ALI presentation, urgent evaluation and management are necessary. Here, we report 3 cases with ALI due to thromboembolism. Conventional open thromboembolectomy was performed with a femoral artery cutdown and antegrade passage of the embolectomy catheter. Further, distal access was created in the dorsalis pedis artery and/or posterior tibial artery at the ankle level. After the retrograde passage of the guidewire and antegrade insertion of the embolectomy catheter, the embolus was completely removed.
