Non-invasive assessment of arterial stenoses in angioplasty surveillance: A comparison with angiography

Abstract

Restenosis should be assessed with imaging of the angioplasty site during angioplasty surveillance.

Management of mixed arterial and venous leg ulcers

“…In some patients, clinical assessment alone cannot accurately diagnose arterial compromise10, 13, 14. Ankle : brachial pressure index (ABPI) measurement and venous imaging using colour venous duplex ultrasonography are validated methods of vascular assessment and can be performed during a single clinic visit15.…”

Peripheral arteries

“…62 The diagnostic potential of these measurements is uncertain. In a study 63 using a velocity ratio >2 to indicate stenosis of >50% 5 days post-procedure, arteries with a residual stenosis exceeding 50% had a significantly worse patency rate (11%) at one year compared with lower levels of residual narrowing, which had patency rates of 80%.…”

What's new in vascular surgery?

“…They found that their primary patency at 1 year was a dismal 22%, leading them to the appropriate conclusion that long segment stent use in superficial femoral artery disease should be reserved for few patients. The optimal method of follow-up after angioplasty has attracted considerable attention, most recently from Nyamekye and associates from the Middlesex Hospital in London [31]. They found, remarkably, that neither symptoms, pulse status, resting ankle brachial index, nor exercise ankle brachial index showed any useful correlation with angiography.…”
