The study aimed to assess the efficacy of customized pressure-guided elastic bandages (CPG-EB) in preventing postoperative edema and complications in Coronary Artery Bypass Graft (CABG) patients. While compression therapy, like compressive stockings, has benefits in preventing edema, concerns about affordability persist. CPG-EB provides optimal sub-bandage pressure, proven effective in venous leg ulcers. Implementing CPG-EB post-CABG could enhance venous blood flow, reducing complications and improving outcomes. Patients were divided into two groups: one with CPG-EB and the other standard post-CABG care. Data collected at 1, 2, and 6 weeks post-surgery assessed swelling and wound complications. Comparative analysis used standardized criteria.
All patients scheduled for elective coronary artery bypass grafting (CABG) surgery with saphenous vein harvesting from the leg at Siriraj Hospital.
Patients aged 18 years and older undergoing CABG surgery with saphenous vein harvesting from the leg at Siriraj Hospital, who willingly consent to participate in the study.
Patients with an Ankle-brachial pressure index (ABI) < 0.8
Patients with severe leg swelling (pitting edema of grade 3 or higher) or with pre-existing or post-operative heart failure that remains uncontrolled despite diuretic therapy.
Patients with occlusive peripheral arterial disease (PAD) or chronic venous insufficiency (CEAP 2s), characterized by significant venous stasis, leg pain, varicose veins, or lymphadenopathy.
