Intermittent compression of the calf and foot to enhance the circulation in ischemic limbs is a hitherto poorly evaluated method. It is now possible to apply controlled compression therapy using mechanical devices. In a pilot study with a prototype device, 8 patients Fontaine stage: III-IV were treated in sessions using an Art Assist, model AA-1000 S/N3 (ACI-Medical, San Marcos, CA, USA) pneumatic compression device, consisting of a cuff around the foot and ankle. Pneumatic compression of 100 mmHg for 3 sec per 20 sec cycle was applied for 15-90 min, with patients in supine position and legs 15° dependent. Treatment effect was measured with air plethysmography (APG) (APG-1000, ACI Medical), transcutaneous oxygen pressure recovery time (TORT) , and visual analogue scale (VAS).
Calf Blood flow increased from 39.9 (26.5) to 50.5 (32.4) ml/min (SD), p=0.0218 (Wilcoxon), TORT diminished from 4.1 (1.6) to 2.9 (0.7) min, p=0.063 (Wilcoxon), VAS indicated subjected improvement after 6/17 sessions. Best results were obtained with sessions <30 min. Longer sessions were poorly tolerated.
These results show that intermittent pneumatic compression may acutely improve the circulation in ischemic limbs. Its long-term effect remains to be established. The clinical value is currently being assessed in a randomized placebo-treatment-controlled blinded trial.
