Successful endovascular treatment in patients with acute thromboembolic ischemia of the lower limb including the crural arteries

AIM: S catheter system in patients with acute limb ischemia (ALI) involving thromboembolic occlusion of the proximal and mid-crural vessels. METHODS: S catheter was used in the proximal segment of the crural arteries. Data related to the clinical examination, Doppler sonography, angiography and follow-up from these patients were further used for analysis. RESULTS: S catheter thrombectomy due to remaining thrombus formation with no reflow was performed in the anterior tibial artery in two of seven cases (29%), in the tibiofibular tract and posterior tibial artery in two of seven cases (29%) and in the tibiofibular tract and fibular artery in the remaining three of seven cases (43%). Ischemic symptoms resolved promptly in all, and none of the patients experienced a procedural complication, such as crural vessel dissection, perforation or thrombus embolization. CONCLUSION: S catheter system may be a safe and effective treatment option in case of thrombotic or thromboembolic occlusion of the proximal and mid-portion of crural arteries.
