Percutaneous transluminal angioplasty and stent placement for subclavian and Brachiocephalic Artery stenosis in aortitis syndrome.
Cardiovascular and interventional radiology, 1999Co-Authors: Motohiro Nomura, Sinya Kida, Tetsumori Yamashima, Junkoh Yamashita, Jun Yoshikawa, Osarru MatsuiAbstract:A 43-year-old man with progressive right common carotid, subclavian Artery, and Brachiocephalic Artery stenoses due to aortitis syndrome is presented. The patient’s right common carotid Artery had been treated by percutaneous transluminal angioplasty (PTA) four times previously, but it was finally occluded. The right subclavian Artery was treated by PTA once, which resulted in restenosis. The stenosis extended to the Brachiocephalic Artery. For this patient, PTA followed by stent placement was performed for the right subclavian and Brachiocephalic Artery stenosis. Because arterial stenosis is progressive in cases of aortitis syndrome, simple PTA alone does not appear to be sufficient for treatment. We suggest that PTA followed by stent placement may be an alternative treatment for recurrent stenosis in aortitis syndrome.

angioplasty with or without stent placement in the Brachiocephalic Artery feasible and durable a retrospective cohort study
Journal of Vascular and Interventional Radiology, 2007Co-Authors: Eline S Van Hattum, Jeanpaul P M De Vries, Ferry Lalezari, Jos C Van Den Berg, Frans L MollAbstract:Purpose To evaluate the results of percutaneous transluminal angioplasty (PTA) and stent placement in isolated Brachiocephalic trunk lesions. Materials and Methods PTA, with or without stent placement, was used to treat 30 patients with isolated clinically significant stenoses ( n = 25) or occlusions ( n = 5) of the Brachiocephalic Artery. Initial clinical success was defined as a relief or substantial reduction of the preprocedural symptoms, and initial technical success was defined as a mean translesion pressure gradient of less than 5 mm Hg or a residual stenosis of less than 20%. Clinical evaluation and duplex Doppler ultrasonography of the lesion site were performed at follow-up. Clinical restenosis was defined as recurrent clinical symptoms and a lumen reduction of more than 50%, determining the primary clinical patency. Technical restenosis was defined as more than 50% lumen reduction with or without renewed clinical symptoms, determining the primary technical patency. Results The initial technical success rate was 83% (occlusions, 60%; stenoses, 88%), and the clinical success rate was 81%. Two patients had major complications, and four experienced minor complications. At a median follow-up of 24 months (4 weeks to 92 months), the primary clinical patency rate was 79% (95% confidence interval [CI]: 57%, 104%), with 83% (95% CI: 60%, 105%) for arteries with stents and 67% (95% CI: 13%, 120%) for those without stents ( P = .11). The primary technical patency rate was 50% (95% CI: 24%, 76%). Conclusion PTA with or without stent placement in a stenotic or occlusive Brachiocephalic Artery is a procedure of tolerable safety with a high initial success rate; however, only moderately rewarding results were obtained after 2 years. Selective stent placement probably improves long-term success. Primary PTA with selective stent placement in an atherosclerotic obstructive Brachiocephalic Artery should be considered the preferred treatment option.
