Key result
Temporary coronary occlusion using suture snare caused more acute damage than silastic loop or bulldog clamp in a pig model, while silastic loop showed some late damage.
Why the study?
Does the method of temporary coronary artery occlusion (suture snare, silastic loop snare, or bulldog clamp) affect the degree of acute and chronic vascular damage in a porcine model?

Suture snare may increase acute vascular injury risk versus alternatives in off-pump CABG; hypothesis-generating for clinical technique trials.
Does the method of temporary coronary artery occlusion (suture snare, silastic loop snare, or bulldog clamp) affect the degree of acute and chronic vascular damage in a porcine model?
Different techniques of temporary coronary artery occlusion cause varying degrees of acute and chronic vascular damage, which may contribute to early postoperative graft occlusion in off-pump bypass surgery.
Hsi et al. (2002) studied Coronary artery occlusion (n=12). Temporary coronary occlusion methods (suture snare, silastic loop snare, bulldog clamp) vs. Comparison among methods was evaluated on Degree of damage to the area of occlusion by light microscopy. Temporary coronary occlusion using suture snare caused more acute damage than silastic loop or bulldog clamp in a pig model, while silastic loop showed some late damage.
