Combined Less-invasive Surgical and Endovascular Technique to Minimise Operative Trauma and Treat Excessive Aortoiliac Thrombotic Obliteration with Popliteo-crural Involvement and Acute Limb Ischaemia

Abstract

This article demonstrates a less-invasive combined surgical and endovascular alternative approach in a case in which an excessive thrombotic formation in the infrarenal aorta caused occlusion of the iliac artery and the ipsilateral crural arteries. A 51-year-old man was admitted to the authors’ hospital with symptomatology of acute lower limb ischaemia. He had undergone endovascular treatment with placement of kissing stents in the common iliac arteries 2 years previously. A CT angiography scan revealed an extensive thrombus formation in the entire infrarenal aorta occluding the distal infrarenal aorta, the iliac artery and the crural arteries. He underwent a hybrid approach, with exposure of only the right common femoral artery and over-the-wire embolectomy of the infrarenal aorta and the iliac artery, and after the restoration of the inflow, an embolectomy of the peripheral vessels was carried out. To cover the residual aortic thrombus and to restore the severe in-stent restenosis of the previously deployed bare stents, three covered balloon-expandable stents were deployed in kissing technique. The patient was discharged on the fourth postoperative day with palpable peripheral pulses. Combined surgical and endovascular techniques minimise the operative trauma and length of hospital stay for the patient, successfully restoring the perfusion in a physiological manner.
