[A single-use vascular clamp. An experimental and clinical study].
Twelve rabbit femoral arteries were clamped for one hour with a TKS2 clamp in order to confirm the atraumatic nature of the Tamai disposable clamp. After 15 or 30 minutes of revascularisation, the arteries were excised and studied by light microscopy and scanning electron microscopy. Temporary dilatation of the artery was observed after removal of the clamp, as the patency test was always positive. Light microscopy revealed parietal flattening without any cellular disorganisation and scanning electron microscopy revealed flattening of the endothelial cells without any tearing. On the basis of these favourable results, combined with the ease of use, we now use the Tamai clamp daily.
