Objective: Compare the evolution regarding the complications concerning two types of incision
(conventional mini-incision), for saphenectomy in patients that go under myocardial revascularization
or otherwise known as coronary artery bypass surgery.
Methods: In January 2012 to August 2013, 66 patients were prospectively selected for coronary artery
bypass with cardiopulmonary bypass surgery. These were divided into two groups: Conventional and
Mini-Incision, with 33 patients in each group chosen in a random fashion and with knowledge of which
technique to be used being presented only at the start of the surgery. In the conventional group, the
patients received an incision to the lower member of 7e10 cm. The patients in the Mini-Incision group
received an incision to the lower member of 3e4 cm, both performed without the use of any special
material.
Results: The groups were similar in terms of clinical data and in the preoperative period. Males made up
a greater part of the group with 63.7% and 81.9% in groups C and M, respectively. Among the complications
analysed, edema (p ¼ 0.011), hematoma (p ¼ 0.020), dehiscence (p ¼ 0.012) and infection
(p ¼ 0.012), were significantly greater in group C when compared to group M. When the matter comes to
the variable in relation to the risk of Surgical Site Infections (SSI), no difference was found between the
groups.
Conclusion: Coronary artery bypass surgery with mini-incision for saphenectomy, demonstrated a lower
rate for preoperative complications when compared to saphenectomy under conventional incision
procedures.
