Prevention of Edema After Coronary Artery Bypass Graft by Customized Pressure-guided Elastic Bandages

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.

Clinical Impact of Surgical Wound Morbidity According to the Type of Saphenous Vein Harvesting Technique (Endoscopic vs. Open) in Patients Undergoing Myocardial Revascularization Surgery

The goal of this clinical trial is to compare two different techniques: endoscopic saphenous vein harvesting versus conventional open harvesting in patients undergoing coronary artery bypass grafting, either alone or in combination with another cardiac surgical procedure (valve surgery or arrhythmia surgery). The main questions the trial aims to answer are: Does the endoscopic technique reduce surgical wound morbidity in terms of shorter hospital stays? Does endoscopic saphenous harvesting reduce the use of antibiotics for saphenectomy wound infections? Does the endoscopic technique reduce need for wound dressings due to necrosis and/or wound infection, and reduce need for analgesic treatment for wound pain? This prospective, randomized study will be conducted in the Cardiovascular Surgery Service at Hospital Clínico San Carlos. Participants will be randomly assigned to a different saphenectomy technique. All patients will be assessed for saphenectomy wound complications upon discharge, and by phone call at 7 days, 1 month, and 3 months following the intervention.

Morbidity of Conventional and No-touch Saphenectomy in Coronary Artery Bypass Grafting.

A clinical research project will be carried out that will consist of a non-inferiority study. The objective is to compare the morbidity of two different surgical techniques for the extraction of the internal saphenous vein, intended to be used as a conduit in coronary bypass.
