Objective: This study evaluates the importance
of intraoperative assessment of transit time flow measurement
of anastomoses for early detection and revision of graft problems.
Method: From September 1998 till March 2001, 323 patients underwent
CABG in Cardiovascular Clinic Tuzla. Total number of distal gafts
was 807 (2,49 per patient). All placed grafts were tested intraoperatively
with transit time flow measurement (TTMF). Results: nineteen grafts
(2,35%) were surgically revised on the basis of unsatisfactory
flow curves, low mean flow or high pulsatile index. In all revised
grafts, significant technical error was found such as intimal
flap, thrombus, graft knicking or dissection. All revised anastomoses
were corrected until the satisfactory TTFM results were obtained,
with no major complications or deaths in entire series of patients.
Conclusion: On the basis of our experience, we strongly recommend
the patency of each graft be assesses perioperatively with TTFM.
Use of TTFM improved surgical results by enabling early detection
of graft problems and immediate intraoperative revision.
Keywords: Flow measurement, patency, revision.
