Percutaneous transluminal angioplasty of the innominate, subclavian, and axillary arteries

Percutaneous balloon angioplasty offers an alternative to surgery for the alleviation of symptoms in upper limb arterial disease. This report documents 28 per-femoral dilatation procedures in 27 patients for 33 subclavian, two innominate, and two axillary lesions. Thirty-four stenoses and three occlusions were treated, with multiple dilatations in five patients. Indications for treatment were: arm ischaemia (15 patients); neurological (steal syndrome) symptoms (8); and combined ischaemia plus steal (5). Angioplasty was technically successful in 27 procedures with symptomatic relief in 25 cases up to a mean follow-up of 24 months (median 20 months, range 2-90 months). One patient had successful repeat angioplasty for recurrent ischaemic symptoms after 30 months. Angioplasty improved pulse deficits in all but two patients and reduced arm blood pressure differential to less than 30 mmHg in all but three patients. There were three complications: a femoral artery occlusion and a groin haematoma required surgical intervention and another patient suffered an extension of a contralateral stroke. Percutaneous balloon angioplasty has proved safe and effective. We recommend angioplasty as the first line treatment for ischaemic or neurological symptoms in upper limb vascular disease.
