Comparison of the Mammary Harvesting Technique

Status Completed

Clinical Trial Summary

The skeletonization technique of left internal artery (LIMA) harvesting is reported as more spar-ing to the vascular supply of the sternum. Some studies report a greater length and greater flow of the graft additionally. The aim of our study was to measure the difference in post-op sternal blood supply compared to the pedicle harvesting technique and to measure the length and flow of the LIMA graft.

Clinical Trial Description

A total of 90 patients were examined in a prospective randomized study. In 60 patients referred for coronary artery bypass grafting (CABG), LIMA was harvested, one-half (n=30) skeletonized, and one-half (n=30) with a pedicle. Thirty patients operated via sternotomy without LIMA harvesting (other procedures, for instance, valve surgery) were the control group. In patients undergoing LIMA harvest, harvest duration, graft length, and graft free flow were measured at defined arterial pressure. In all patients, the sternal blood flow was examined by active dynamic thermography (DIRT): first preoperatively and on 4th postoperative day. During this, the time of spontaneous rewarming of the skin surface after the application of a cold stimulus was measured in the caudal part of the sternum. The difference between postoperative and preoperative time was calculated and compared between groups. ;
