OBJECTIVE: The aim of this study was to identify lymphoscintigraphic changes associated with lower-extremity oedema after the harvesting of the saphenous vein using a series of short Q2 incisions for coronary bypass.
METHOD: Forty-four patients (32 males and 12 females) with a mean age of 62.7 ± 7.8 (47-75 years old) were evaluated in a retrospective, quantitative, cross-sectional study from June 2007 to January 2008, three to 188 months (mean: 46 months) after the surgical procedure. Assessment was by water displacement volumetry and lymphoscintigraphy of the lower limbs. Results expressed as means with standard deviations were compared employing the Student's t-test and the chi-square or Fisher's exact tests were used to compare data expressed as frequencies. An alpha error of 5% was considered acceptable (P ≤ 0.05).
RESULTS: The presence of dermal backflow, as identified by lymphoscintigraphy with an accumulation of radiotracer in the thoracic duct and popliteal lymph nodes was significantly greater on the operated side.
CONCLUSION: There was a significant association between dermal backflow and delayed oedema.
