摘要

BACKGROUND. Although surgical endarterectomy or bypass is regarded as the treatment-of-choice for extracranial cerebral vascular stenosis, percutaneous transluminal angioplasty (PTA) has its role as an alternative procedure for symptomatic patients refractory to medical therapy and/or for whom surgical treatment is contraindicated. METHODS. Occlusive blood vessels were first identified by neurologic, ultrasonic and angiographic studies. Patients were premedicated with heparin and corticosteroid. From a transfemoral approach, double lumen balloon dilatation catheter was guided across the area of stenosis, and inflated two or three times to produce dilatation. Following PTA, patients received anticoagulants and corticosteroid for a period, and were followed by clinical examination, Doppler blood-flow and angiographic studies. RESULTS. Seventeen patients undergoing 26 procedures were included in this study. The lesions involved subclavian artery in nine cases, common carotid artery in seven, internal carotid artery in five and proximal vertebral artery in five. Digital subtraction angiography (DSA) was done immediately after PTA and showed improvement of stenotic segment (residual stenosis < 30%) in 22 vessels. Restenosis occurred in two cases of subclavian artery PTA six months later. There were three complications, including TIA in two cases and hematoma at the puncture site in one case. Clinically, symptomatic improvement was obtained in 13 cases. CONCLUSIONS. In patients with significant atherosclerotic stenosis of neck vessels, PTA is a beneficial procedure for improving blood flow to brain circulation and for alleviating symptoms.
