Summary: | Background: Doppler sonography is a type of sonography used for imaging the blood flow in the vessels and
heart. This technique uses ultrasound waves with high frequency. In some patient candidates for venous graft, the
identification of the suitable vein is not possible with clinical examination.
Objective: This study compared the effects of preoperative color Doppler sonography of lower extremity veins
on the postoperative outcomes of saphenectomy.
Methods: This randomized clinical trial was conducted on 100 candidates of an off-pump coronary artery bypass
graft (CABG) hospitalized in Afshar Hospital in Yazd in 2015. Patients were divided into two groups: 50 patients
in the study group and 50 patients in the control group. Patients in the study group underwent color Doppler
sonography of lower extremity veins using the Medison 8000 Live device. Patients in the control group were
assessed preoperatively by routine venous examination without undergoing color Doppler sonography. The
prepping and draping methods and also the preoperative antibiotics were the same for both groups. The patients
were assessed for wound infection, edema, hematoma, and DVT 2 days, 1 week, and 1 month after surgery. Data
were analyzed by SPSS version 16 using t-test, Chi-square, and Fisher’s exact test.
Results: The length of incision for saphenectomy was 29.20 ± 3.71 cm in the Doppler group and 28.98 ± 3.72 cm
in the non-Doppler group with no significant difference between the two groups (p=0.768). The two groups were
not significantly different with respect to age, gender, diabetes, hypertension, hyperlipidemia, smoking, and
history of peripheral vessels disease, postoperative infection, postoperative organ edema, postoperative
hematoma, and postoperative DVT.
Conclusion: Preoperative color Doppler sonography of the saphenous vein before saphenectomy has no effect on
reducing the postoperative complications, and saphenectomy on the basis of intraoperative examination of the
vein course by the surgeon has acceptable consequences.
Clinical trial registration: The trial was registered at the Thai Clinical Trials Registry (TCTR)
(http://www.clinicaltrials.in.th) with the TCTR ID: TCTR20160708001.
