Abstract:
Objective To evaluate the efficacy of dual stent placements for the treatment of occlusion/stenosis of subclavian artery associated with stenosis of adjacent vertebral artery initial site. Methods The clinical data of 9 patients with occlusion/stenosis of subclavian artery associated with stenosis of adjacent vertebral artery initial site were retrospectively analyzed. Stent implantations in the affected subclavian artery and vertebral artery were separately performed; the patients were followed up for 3-12 months after the treatment. The therapeutic efficacy was evaluated with the clinical symptoms and Doppler ultrasonic examination. Results Successful implantation of two stents was accomplished in all 9 patients, with the technical success rate of 100%. After the treatment, the blood flow in both the subclavian and vertebral arteries was unobstructed. Following-up examination showed that the subjective symptoms were obviously improved in all 9 patients, and no serious procedure-related complications occurred. Doppler ultrasound examination showed that no in-stent restenosis or stent displacement was observed. Conclusion For the treatment of occlusion/stenosis of subclavian artery associated with stenosis of adjacent vertebral artery initial site, dual stent placement technique is a safe and feasible means with satisfactory effect in improving vertebro-basilar arterial insufficiency.
