Perioperative routines and surgical techniques for saphenous vein harvesting in CABG surgery: a national cross-sectional study in Sweden.

ABSTRACT: BACKGROUND:The saphenous vein is the most commonly used conduit for coronary artery bypass grafting (CABG). Wound healing complications related to saphenous vein harvesting are common, with reported surgical site infection rates ranging from 2 to 20%. Patients' risk factors, perioperative hygiene routines, and surgical technique play important roles in wound complications. Here we describe the perioperative routines and surgical methods of Swedish operating theatre (OT) nurses and cardiac surgeons. METHODS:A national cross-sectional survey with descriptive design was conducted to evaluate perioperative hygiene routines and surgical methods associated with saphenous vein harvesting in CABG. A web-based questionnaire was sent to OT nurses and cardiac surgeons at all eight hospitals performing CABG surgery in Sweden. RESULTS:Responses were received from all hospitals. The total response rate was 62/119 (52%) among OT nurses and 56/111 (50%) among surgeons. Chlorhexidine 5?mg/mL in 70% ethanol was used at all eight hospitals. The OT nurses almost always (96.8%) performed the preoperative skin disinfection, usually for three to 5 minutes. Chlorhexidine was also commonly used before dressing the wound. Conventional technique was used by 78.6% of the surgeons, "no-touch" by 30.4%, and both techniques by 9%. None of the surgeons used endoscopic vein harvesting. Type of suture and technique used for closing the wound differed markedly between the centres. CONCLUSIONS:In this article we present insights into the hygiene routines and surgical methods currently used by OT nurses and cardiac surgeons in Sweden. The results indicate both similarities and differences between the centres. Local traditions might be the most important factors in determining which procedures are employed in the OT. There is a lack of evidence-based hygiene routines and surgical methods.

Project description:BackgroundThe objective of this study is to examine factors associated with thrombus extension after early experience with mechanochemical ablation, which combines mechanical damage to the venous endothelium with infusion of a sclerosant.MethodsA retrospective review was performed of patients who underwent mechanochemical ablation to treat saphenous vein insufficiency in the thigh including the saphenofemoral junction. Data abstracted included patient demographics, procedural details, and postprocedural outcomes. Thrombus extension was determined by postprocedural duplex ultrasound and classified as flush closure with the femoral vein and any extension of thrombus into the femoral vein.ResultsSeventy-three patients met inclusion criteria. The mean age of the population was 60, 17.8% were female, and the mean body mass index (BMI) was 30.7. Seven (9.6%) patients who underwent mechanochemical ablation experienced saphenous vein closure flush with the femoral vein. Eleven (15%) patients experience extension of thrombus to less than 50% of the diameter of the femoral vein and one patient experienced complete thrombosis of the femoral vein. There was no significant difference in age, sex, or comprehensive classification system for chronic venous disorders between the group with thrombus extension and the group without, with the exception of BMI. The mean BMI in the group with thrombus extension was 26.8 vs. 32 in the group without (P = 0.02). There was no significant difference between the 2 groups in sclerosant volume used, distance between catheter tip and SFJ, and mean diameter of GSV in the thigh.ConclusionsIn this cohort, the incidence of thrombus extension into the femoral vein with mechanochemical ablation was high relative to rates of thrombus extension associated with reported rates of thermal ablation. Further investigation with larger cohorts, and standardized reporting is required to characterize the true rate of thrombus extension after mechanochemical ablation and identify maneuvers which may prevent thrombus extension.
