wound infection in bilateral mammary diabetic patients

BACKGROUND: Glycated hemoglobin (HbA1c) is a suspected risk factor for sternal wound infection (SWI) after CABG.Methods and Results:Data on preoperative HbA1c and SWI were available in 2,130 patients undergoing isolated CABG from the prospective E-CABG registry. SWI occurred in 114 (5.4%). Baseline HbA1c was significantly higher in patients with SWI (mean, 54±17 vs. 45±13 mmol/mol, P<0.0001). This difference was also observed in patients without a diagnosis of diabetes (P=0.027), in insulin-dependent diabetic (P=0...

BACKGROUND: The use of bilateral internal mammary arteries (BIMA) is limited worldwide, especially in patients with chronic obstructive pulmonary disease (COPD). Thus, we assessed the safety of the use of BIMA in COPD patients. METHODS: From cohorts of 8846 patients operated on at our center for primary isolated multi-vessel coronary bypass operations between 2002 and 2012, we studied two propensity-matched groups of patients with COPD who received either single internal mammary artery and saphenous vein grafts (SIMA group: 137 patients) or exclusively BIMA (BIMA group: 137 patients)...

The incidence of sternal wound infections (SWI) after coronary artery bypass surgery (CABG) as reported worldwide is low. However, it is associated with significant increase of postoperative mortality and treatment costs. The major risk factors discussed are diabetes mellitus and bilateral IMA harvesting of the internal mammary artery. This study analyses data of 590 patients receiving CABG concerning the risk factors for SWI. Sternal wound infections occur significantly more often in diabetic patients, one crucial and significant additional risk factor is obesity...

OBJECTIVES: Deep sternal wound infection (DSWI), especially in patients with diabetes mellitus (DM), is a major concern after coronary artery bypass grafting (CABG) with bilateral internal mammary artery (BIMA) grafts. We evaluated the risk of DSWI and other clinical outcomes between continuous insulin infusion therapy (CIT) and insulin sliding scale therapy (IST) in a cohort of DM patients who underwent CABG with BIMA. METHODS: The clinical records of DM patients who underwent isolated CABG with BIMA were retrospectively reviewed...

This study examined the effect of coronary artery bypass graft surgery with bilateral internal thoracic artery grafting in diabetic patients. Coronary artery bypass graft surgery using skeletonized bilateral internal thoracic artery grafts was not associated with an increased risk of deep sternal wound infection or early death. Moreover, patients who underwent coronary artery bypass graft surgery using bilateral internal thoracic artery grafting had lower remote mortality and cardiac mortality. We conclude that coronary artery bypass surgery using bilateral internal thoracic artery grafts is an excellent strategy, even for diabetic patients...

Coronary artery disease (CAD) is a leading cause of mortality and morbidity in diabetics. Diabetics make up to 20%-35% of all patients undergoing coronary revascularization. Patients with diabetes represent a particularly difficult subset for revascularization due to increased short- and long-term mortality as well as a higher risk of repeat revascularization procedures. Potential factors contributing to the increased risk include co-morbid illnesses, small, diffusely diseased target vessels, progression of native CAD, hyperglycaemic endothelial dysfunction, and systemic inflammation...

BACKGROUND: It is suggested that the internal thoracic artery (ITA) harvesting technique influences the incidence of sternal wound infection (SWI) after coronary artery bypass graft (CABG) surgery when both right and left ITAs are used. We conducted a meta-analysis to determine whether there is any difference between skeletonized versus pedicled bilateral ITA in terms of SWI after CABG. METHODS: We performed a systematic-review using MEDLINE, EMBASE, CENTRAL/CCTR, SciELO, LILACS, Google Scholar and reference lists of relevant articles to search for studies that compared the incidence of SWI after CABG between skeletonized versus pedicled bilateral ITA until May 2014...

Coronary artery bypass graft surgery relieves angina symptoms and reduces mortality among ischaemic heart disease patients. It remains the gold standard for the treatment of multi-vessel and left main coronary artery disease. It is a well-known fact that internal mammary artery conduits have excellent and long-lasting patency when used for coronary artery bypass grafting. Its supremacy is largely because it prevents atherosclerosis. The old-style internal mammary artery bypass grafting, classically known as pedicle grafting, includes a circular rim of tissue around the graft...

OBJECTIVE: Additional arterial grafts such as the right internal mammary artery (RIMA) or the radial artery (RA) have been proposed to improve long term outcomes in coronary artery bypass grafting (CABG). RA is largely preferred over RIMA as it is less technically demanding and there is a perception that bilateral IMA usage increases the risk of sternal wound complications. However, there is a paucity of direct comparison of the two conduits to guide surgeons to choose the best second arterial conduit for CABG...

OBJECTIVE: Coronary artery bypass graft (CABG) surgery with arterial conduits is considered optimal. A deterrent to bilateral internal thoracic artery (BITA) grafting is the risk of deep sternal wound infection (DSWI). We introduced infection prevention measures sequentially, attempting to reduce DSWIs. The aim was to determine (1) if the absence of DSWIs in the last 469 of 1001 consecutive operations was significant; (2) which measures explained the change; and (3) the impact of diabetes...

BACKGROUND: We sought to assess the risk and late outcome of bilateral internal thoracic artery grafting in eligible insulin-treated diabetic subsets. METHODS: 147 insulin-treated diabetic patients undergoing arterial revascularization were grouped as: skeletonized bilateral internal thoracic artery (n = 83) or internal thoracic artery-radial artery (n = 64). Chronic lung disease or overweight and female constituted exclusion criteria for bilateral internal thoracic artery grafts...

OBJECTIVES: The use of bilateral internal thoracic arteries (BITA) has been associated with improved long-term outcomes following coronary artery bypass graft (CABG) surgery. The objective of this study was to evaluate the impact of BITA use on long-term survival among patients with low ejection fraction (EF) undergoing CABG. METHODS: Between April 1991 and October 2011, 2035 consecutive patients underwent primary BITA grafting. Among them, there were 129 patients with left ventricular EF ≤40%...

Arterial coronary grafts can be used in the majority of patients and have better patencies than saphenous vein grafts (SVGs), resulting in excellent perioperative and superior long-term outcomes. Barriers to their extensive use include potential for trauma and spasm, extra-operating time, unfamiliarity, concerns over hypoperfusion and deep sternal wound infection in patients in whom bilateral internal thoracic arteries are used-especially diabetics. This presentation addresses these concerns with particular attention to the radial artery, and skeletonized right internal thoracic artery harvest and construction of the proximal anastomoses of these grafts to the ascending thoracic aorta...

OBJECTIVES: To analyze our experience of conducting Bilateral Internal Mammary Artery (BIMA) grafting, using both pedicled and free grafts for coronary revascularization, assessing the safety and efficacy of the procedure and comparing any differences observed between the two techniques of harvesting the grafts. METHODS: A retrospective cross sectional study was conducted in July 2010 in which all 48 patients undergoing bilateral internal mammary artery grafting for coronary bypass surgery at the Aga Khan University Hospital from 1996 to 2010 were reviewed and evaluated...

OBJECTIVES: Limited blood supply to the thoracic chest wall is a known risk factor for sternal wound complications after CABG. Therefore, bilateral internal thoracic arteries are still rarely utilized despite their proven superior graft patency. The aim of our study was to analyse whether modification of the surgical technique is able to limit the risk of sternal wound complications in patients receiving bilateral internal thoracic artery grafting. METHODS: All 418 non-emergent CABG patients receiving bilateral internal thoracic artery CABG procedures (BITA) from January 2001 to January 2012 were analysed for sternal wound complications...

OBJECTIVES: The objective of this study was to investigate the impact of bilateral internal mammary artery (BIMA) on early outcomes after coronary artery bypass grafting. DESIGN: Retrospective database analysis. SETTING: US hospitals. PATIENTS: 1 526 360 patients (mean age 65 years, 73% male) from the Nationwide Inpatient Sample from 2002-2008 who underwent isolated coronary artery bypass grafting with at least one internal mammary artery...

BACKGROUND: The advantageous survival outcome of bilateral internal mammary artery grafting (BIMA) has been well established. However, this meta-analysis aims to make clear whether BIMA grafting increases the risk of sternal wound infection (SWI) when compared with single internal mammary artery grafting (SIMA). METHODS: A literature search was performed in PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials. The observational studies reporting a comparison between SIMA and BIMA were included...

It is suggested that the internal thoracic artery (ITA) harvesting technique influences the incidence of sternal wound infection (SWI) after coronary artery bypass graft (CABG). To determine if there is any real difference between skeletonized vs pedicled ITA, we performed a meta-analysis to determine if there is any real difference between these two established techniques in terms of SWI. We performed a systematic review using MEDLINE, EMBASE, CENTRAL/CCTR, SciELO, LILACS, Google Scholar and reference lists of relevant articles to search for studies that compared the incidence of SWI after CABG between skeletonized vs pedicled ITA until June 2012...

OBJECTIVE: A common perception is that use of pedicled bilateral internal mammary arteries (BIMA) increases the risk of sternal wound complications in diabetic patients undergoing coronary artery bypass grafting (CABG). The purpose of this study was to compare the in-hospital outcomes of CABG using pedicled BIMA in diabetic and nondiabetic patients. METHODS: From September 1998 to September 2010, 390 consecutive diabetic patients and 519 nondiabetic patients underwent isolated off-pump CABG using pedicled BIMA...
