Percutaneous transluminal angioplasty of the subclavian artery: early and late results


, : Percutaneous transluminal angioplasty of the subclavian artery: early and late results. Cardiovascular and Interventional Radiology 10(3): 123-128

Percutaneous transluminal angioplasty of 23 subclavian arteries was attempted in 22 patients. Dilatation was successful in 3 of 4 right subclavian artery stenoses and 18 of 19 left subclavian artery stenoses. The primary clinical indication was posterior fossa ischemia in 11 patients, upper limb ischemia in 14 and both symptoms in 6. In 2 patients, dilatation of an asymptomatic high-degree left subclavian artery stenosis was performed before coronary artery bypass surgery using the internal mammary artery. Eighteen patients on follow-up over 6-60 months (mean 25 months) are free of symptoms with equivalent systolic blood pressures in both arms. Three patients showed relapse of the stenosis after 8, 12, and 15 months; one was successfully treated with a second dilatation. Complications consisted of an occlusion at the left axillary artery puncture site and a distal embolus to a finger artery. Percutaneous transluminal angioplasty appears safe and efficient therapy for subclavian artery stenoses with excellent short- and long-term results.
