Surgery and Stenting As Combined Treatment of a Symptomatic Tandem Stenosis of the Carotid Artery

¶ International co-operative studies have demonstrated a benefit from surgery for symptomatic and asymptomatic patients affected by internal carotid artery stenosis of 60–70%. The presence of a tandem lesion, intracranial or extracranial, may annul the benefit of surgery. Such patients may thus represent a challenging problem for management if age, good general conditions and a normal neurological status favour a therapy. A 54-year-old man developed transient ischaemic attacks of the left hemisphere; his general condition was good, and neurological status was normal. Angiography showed a tight stenosis at the left common carotid artery near the ostium and at the homolateral carotid bifurcation. At first, a self-expanding wall stent was placed at the level of the common carotid artery stenosis, and immediately after a standard endarterectomy under general anaesthesia was performed. The postoperative course was normal and was complicated only by the presence of a mild deficit of the hypoglossal nerve due to the presence of a high bifurcation. The early and late outcome of our case suggests that stenosis of the proximal common carotid artery may be successfully treated by stenting. While awaiting additional data about this new technology, endovascular techniques and surgery may be complementary in the management of patients suffering from such tandem lesions.
