AIM: In this prospective study, we aimed to compare flow characteristics and the short term patency of sequential and y-grafts by intraoperative transit time flow measurement.
METHODS: Sixty patients were selected from 1374 isolated coronary bypass operations. Group 1 (N.=36) consisted of sequential grafted, Group 2 (N.=24) consisted of y-grafted patients. Intraoperative graft flow measurement was done with a transit time flow meter at stable hemodynamic conditions. We follow up the groups at the 30th day of the operation.
RESULTS: The mean flows at measurement set up were 43.2±19.7 mL/min in Group 1 and 43.6±21.7 mL/min in Group 2. After distal graft clamp removal the same values were 63.4±20.9 mL/min in Group 1 and 67.3±35.3 ml/mins in Group 2. At the 30th day of the operation no patients died, and none of them had an acute myocardial infarction.
CONCLUSION: The percent of flow increase in sequential graft group was higher but the difference of the percent of flow increase between groups was not statistically significant.
