ABSTRACT
OBJECTIVES: The purpose of our study is to illustrate by five original observations the various situations where the stenting of the left main coronary artery can be proposed in alternative to aortocoronary bridging with encouraging results in short- and long-term. MATERIALS AND METHODS: We report a retrospective study relating to five cases with left main disease treated by stenting between 1996 and 2002 at our institution. In two cases the left main stem was unprotected. In two other cases, the left main trunk was protected. And the last case was an emergency stenting for an iatrogenic dissection of the left main coronary artery. RESULTS: The stenting was carried out successfully among the five patients without major in-hospital complication. During the follow-up of 29 months at mean, no death was deplored, and no target lesion revascularization was required on the left main coronary artery (with a left main trunk permeable on three coronarographic controls). CONCLUSIONS: In the light of these results, and basing on the published data, we conclude that stenting for the left main coronary disease may be a safe and effective alternative to coronary artery bypass surgery in particular cases among "selected" patients (refusal or surgical contraindication, protected left main coronary artery, spontaneous or iatrogenic acute occlusion of the left main coronary artery).

The aim of our study was assess anatomical and functional results of renal artery angioplasty with and without stenting in 25 hypertensive patients (8 female and 16 male, 42.6 and 61.6 years old respectively) with significative renal artery stenosis (RAS) (atherosclerotic: 22; fibrodysplastic: 3). Eleven patients had simple angioplasty and 13 had stenting. The rate of angioplasty success was 96%. In the stent group, the anatomical result was better: 2% of residual stenosis versus 24% in the other group (p < 0.001). Restenosis occurred in 2 patients. Immediately after revascularisation arterial blood pressure decreased from 195/105 +/- to 150/85 +/- mmHg in-group without stent (p < 0.001) and from 190/100 to 145/85 mmHg in the group (p < 0.001). The value of serum creatinine concentration in patient with renal failure didn't change after revascularization.

The authors report the case of a 70 year old woman followed up in our Department for ischaemic heart disease since 1991 and admitted to the Intensive Care Unit in November 1996 for unstable angina. Coronary angiography showed significant stenosis of the left main coronary artery, a severe stenosis of the LAD and occlusion of the right coronary artery. Angioplasty of the middle segment of the LAD and left main coronary arteries with implantation of a stent was performed because of resistance to medical therapy and a contra-indication to surgery. Four months later, recurrent anginal pain led to a repeat angioplasty of the LAD with a satisfactory immediate result. The initial procedure on the left main coronary artery was successful and follow up was uncomplicated.

A serious epidemic of Acinetobacter baumannii resistant to imipenem occurred in the surgical intensive care unit of the hospital Charles-Nicolle in Tunis during February 1994, causing two deaths among three patients. The Acinetobacter strains were isolated from various samples of the intensive care unit. The techniques used for typing were biotyping, antibiogram, plasmid profiles and chromosomal DNA by random amplified polymorphic DNA (RAPD). The A baumannii strains isolated from patients exhibited an identical pattern with all the epidemiological markers utilized; the strains from the surrounding areas showed four and six different patterns respectively for phenotypic and genotypic characters. The strain isolated from a care table had the same phenotypic and genotypic pattern as that of the patients' strains.
