Background: There is scarcity of data regarding great saphenous vein harvest site infection incidence
after coronary artery bypass grafting in our geographic location, therefore we aimed to determine
the exact burden of the disease so that appropriate strategies could be made if it comes out to be
major public health problem.
Material and Methods: This Cross-sectional study was conducted at Cardiothoracic Surgery
Department, Aga Khan University Hospital, Karachi, from April 2014 to October 2014 on 163
patients selected through Non- probability, consecutive sampling. All adult patients 18 years and
above with coronary artery disease who underwent coronary artery bypass grafting. Data was
analyzed using SPSS version 17. Chi-square test was applied to see the effect of age, gender, diabetes,
smoking, hypertension, obesity, prolonged ICU stay, use of IABP, aortic cross clamp time and
number of vein grafts harvested, on outcome variable (harvest site infection). P value of <0.05 was
considered statistically significant.
Results: Harvest site infection was 1.5%. Variables studied i.e. age, gender, diabetes, hypertension,
length of ICU stay, obesity, smoking; IABP, cardiopulmonary bypass time, aortic cross clamp time
and number of vein grafts harvested had no statistical significant effect on the frequency of harvest
site infection post coronary artery bypass grafting.
Conclusion: In our study, infection rate was reported 1.5% (2 patients) which is much lower as
compared to the reported frequency in literature. This may be due to small sample size as compared
to the studies in literature.
