We report a case of successful treatment of postoperative saphenectomy wound infection of the upper left leg with the antibiotic drug Daptomycin.
Since its first clinical use by Rene Favaloro in the 60's, the great saphenous vein has become the most commonly harvested conduit for revascularization in coronary artery bypass grafting (CABG) . In order to reduce morbidity and improve the recovery time associated with CABG procedures, various techniques have been developed including conventional conduit harvesting, minimally invasive and/or endoscopic harvesting procedures . Still, these surgical techniques are associated with significant complication rates e.g. wound infections, non-infective wound healing disturbances, postoperative pain, etc. . Avoiding and/or reducing these complication rates is of great medical and economic interest. Improvements would result in increased postoperative mobility and quality of life as well as reduced length of hospital stay following surgery resulting large cost savings. Although much research has focused on comparing less invasive and conventional harvest techniques, there is at present no consensus on the areas of postoperative antibiotic drug treatment of saphenectomy wound infections once an infection occurs. Further studies are required to compare treatment methods of saphenectomy wound infections by different antibiotic drugs. Although, Daptomycin has already been proven to be effective in the treatment of bacteremia and endocarditis [4, 5] caused by methilin-resistent Staphylococcus aureus [6, 7] and several case reports about its effectiveness in the field of cardiac surgery exist in the literature , there are still no cases describing the successful treatment of saphenectomy wound infections by Daptomycin.
Therefore, in this paper we report the first case of successful treatment of a postoperative wound infection after saphenectomy of the great saphenous vein of the upper left leg with the new antibiotic drug Daptomycin (Cubicin®, Novartis Pharma Corporation, Germany).
We report the case of a 68-year old man with severe, diffuse coronary artery disease who presented with two months of progressive angina-pectoris-symptoms. Coronary angiography verified 3-vessel-disease with significant stenoses of the main coronary branches (LAD 99%, RCX 80%, RCA 90%), moderately-decreased systolic left-ventricular function and ST-elevations in leads II, III and aVF. For these reasons, surgical revascularization was indicated. The patient had a significant history of arterial hypertension, Type II diabetes mellitus, adipositas, nicotine abuse (49 pack years), hypercholersterinemia and performance of PTCA of the left coronary artery in 2002.
In the Department of Thoracic-, Cardiac- and Vascular Surgery of the University of Goettingen, Germany, we performed CABG with three single vein-grafts to the diagonal branch (DB), right posterior descending artery (RPD) and left posterolateral circumflex artery (LPL). The left anterior descending artery (LAD) was revascularized by the left internal mammarian artery (LIMA). Harvest of the saphenous vein was performed by conventional open saphenectomy harvest technique which involved an incision extending from the left medial malleolus, along the medial aspect of the knee to the groin.
Written informed consent was obtained from the patient for publication of this case report and accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal.
We gratefully thank Mrs. A. Pencz and Mrs. A. Kiel for technical support of this study.
