A decision support model to predict the presence of an acute infiltrate on chest radiograph.

A chest infiltrate is needed to make a diagnosis of community-acquired pneumonia, but chest X-rays might be time consuming, entail radiation exposure, and demand resources that are not always available. We sought to derive a model to predict whether a patient will have an infiltrate on chest X-ray (CXR). This prospective observational study included patients visiting the Emergency Department of Beilinson Hospital in the years 2003-2004 (derivation cohort) and 2010-2011 (validation cohort), who had undergone a CXR, and were suspected of having a respiratory infection. We excluded all patients with possible healthcare associated infections. A logistic regression model was derived and applied to the validation cohort. A total of 1,555 patients met inclusion criteria: 993 in the derivation cohort and 562 in the validation cohort with 287 (29%) and 226 (40%) having an infiltrate, respectively. The derivation model area-under-the curve (AUC) was 0.79 (95% CI 0.76-0.82). We categorized the patients into three groups-presence or absence of infiltrate, or undetermined. In the validation cohort, 70 (12%) patients were classified as 'no infiltrate'; 3 (4%) of them had an infiltrate, 367 (65%) were classified as 'infiltrate'; 190 (52%) of them had an infiltrate on CXR, and 125 (46%) were classified as 'undetermined'; 33 (26%) of them with an infiltrate on CXR. Using this prediction model for the evaluation of patients with suspected respiratory infection in an ED setting may help avoid over 10% of CXRs.

No post-conditioning in the human heart with thrombolysis in myocardial infarction flow 2-3 on admission.

AIMS: Proof-of-concept evidence suggests that mechanical ischaemic post-conditioning (PostC) reduces infarct size when applied immediately after culprit coronary artery re-opening in ST-elevation myocardial infarction (STEMI) patients with thrombolysis in myocardial infarction 0-1 (TIMI 0-1) flow grade at admission. Whether PostC might also be protective in patients with a TIMI 2-3 flow grade on admission (corresponding to a delayed application of the post-conditioning algorithm) remains undetermined. METHODS AND RESULTS: In this multi-centre, randomized, single-blinded, controlled study, STEMI patients with a 2-3 TIMI coronary flow grade at admission underwent direct stenting of the culprit lesion, followed (PostC group) or not (control group) by four cycles of (1 min inflation/1 min deflation) of the angioplasty balloon to trigger post-conditioning. Infarct size was assessed both by cardiac magnetic resonance at Day 5 (primary endpoint) and cardiac enzymes release (secondary endpoint). Ninety-nine patients were prospectively enrolled. Baseline characteristics were comparable between control and PostC groups. Despite comparable size of area at risk (AAR) (38 ± 12 vs. 38 ± 13% of the LV circumference, respectively, P = 0.89) and similar time from onset to intervention (249 ± 148 vs. 263 ± 209 min, respectively, P = 0.93) in the two groups, PostC did not significantly reduce cardiac magnetic resonance infarct size (23 ± 17 and 21 ± 18 g in the treated vs. control group, respectively, P = 0.64). Similar results were found when using creatine kinase and troponin I release, even after adjustment for the size of the AAR. CONCLUSION: This study shows that infarct size reduction by mechanical ischaemic PostC is lost when applied to patients with a TIMI 2-3 flow grade at admission. This indicates that the timing of the protective intervention with respect to the onset of reperfusion is a key factor for preventing lethal reperfusion injury in STEMI patients.

Asymmetric adaptation to indolic and aliphatic glucosinolates in the B and Q sibling species of Bemisia tabaci (Hemiptera: Aleyrodidae).

The role glucosinolates play in defending plants against phloem feeders such as aphids and whiteflies is currently not clear as these herbivores may avoid bringing glucosinolates from the phloem sap into contact with myrosinase enzymes. Here, we investigated the effects of high levels of aliphatic and indolic glucosinolates on life history traits and detoxification gene expression in two sibling species, B and Q, of the whitefly Bemisia tabaci. High levels of aliphatic glucosinolates decreased the average oviposition rate of both species and reduced the survival and developmental rate of Q nymphs. High levels of indolic glucosinolates decreased the oviposition rate and survival of nymphal stages of the B species and the developmental rate of both species. Molecular analyses revealed two major asymmetries between the B and Q species. First, specific GST genes (BtGST1 and BtGST2) were significantly induced during exposure to indolic glucosinolates only in Q. This may reflect the genes putative involvement in indolic glucosinolates detoxification and explain the species' good performance on plants accumulating indolic glucosinolates. Second, the constitutive expression of eight of the 10 detoxification genes analysed was higher in the Q species than in the B species. Interestingly, four of these genes were induced in B in response to high levels of glucosinolates. It seems, therefore, that the B and Q species differ in their 'optimal defence strategy'. B utilizes inducible defences that are profitable if the probability of experiencing the stress is small and its severity is low, while Q invests significant resources in being always 'ready' for a challenge.

Efficacy of etanercept on rheumatic signs and pulmonary function tests in advanced ankylosing spondylitis: results of a randomised double-blind placebo-controlled study (SPINE).

OBJECTIVES: Patients with advanced ankylosing spondylitis (AS) experience disability because of reduced spinal mobility and pulmonary function impairment. This placebo-controlled study evaluated the effect of etanercept (ETN) in patients with advanced AS. METHODS: A multicentre randomised double-blind placebo-controlled trial of 12 weeks' duration was performed. Patients had definite (modified New York criteria), active (Bath AS Disease Activity Index (BASDAI) ≥40), severe (radiological intervertebral bridges) AS refractory to non-steroidal anti-inflammatory drugs and were antitumour necrosis factor naive. They were treated with ETN 50 mg once weekly or identical placebo (PBO). RESULTS: Of the 95 patients screened, 82 were randomised to receive ETN (n=39) or PBO (n=43). At baseline the disease was active (mean BASDAI 61.0±13.4, C reactive protein (CRP) 20.7±25.5 mg/l) and severe (mean Bath AS Metrology Index (BASMI) 5.7±1.3, mSASSS 36.5±20.5); forced pulmonary vital capacity (FVC) was 3.3±0.7 l. Improvement in BASDAI (normalised net incremental area under the curve between baseline and week 12, primary end point) was significantly greater in the ETN group than in the PBO group (-19.8±16.5 vs -11.0±16.4, p=0.019). Moreover, at week 12, ETN gave better results than PBO for the BASDAI (-26.4±19.7 vs -14.4±19.7; p=0.008), total back pain (-29.2±24.0 vs -14.9±24.0; p=0.010), BASFI (-21.7±17.6 vs -10.1±17.6; p=0.004), BASMI (-0.6±0.6 vs -0.2±0.6; p=0.011), CRP level (-15.7±14.2 vs -1.3±14.2; p<0.001) and FVC (+160±280 ml vs -20±280 ml; p=0.006). CONCLUSIONS: ETN has short-term efficacy for patients with advanced AS, as was previously reported for less advanced disease. The efficacy is observed for the main symptoms (pain) and on markers of inflammation (CRP), as well as disease severity in terms of spinal mobility and pulmonary function.

Asymmetry in thermal tolerance trade-offs between the B and Q sibling species of Bemisia tabaci (Hemiptera: Aleyrodidae).

We investigated life history trade-offs related to thermal tolerance in two sibling species, commonly referred to as the B and Q biotypes, of Bemisia tabaci. We focused on basal resistance to short unpredicted heat stress, which reflects the organism investment, during both optimal and stressful conditions, in insuring its survival. At 27 °C, the relative reproductive performance of B was seven-fold higher than Q. After short stress of 42 °C, these differences increased to 23-fold. A turnover took place after short stress of 43 and 45 °C, in which Q adults performed better. As the expression of the analysed Hsp70 and other stress-related genes was found to be higher in the Q species, our data likely reflects two different strategies for optimal performance. B lowers soma protection for achieving maximum reproduction ('direct inhibitory' trade-off model), whereas Q invests significant resources in being always 'ready' for a challenge.

Ovarian Non-Hodgkin Lymphoma Revealed by Bone Metastasis: A Rare Pediatric Case.

Ovary involvement of non-Hodgkin lymphoma (NHL) is rare. We report a rare case of ovarian NHL during adolescence revealed by bone metastasis. The diagnosis of malignant lymphoma was established after adnexectomy and histological study of the excised tissue. The tumor was classified as a diffuse large B-cell lymphoma. The patient has been treated according to the LMB French protocol with good outcome after two years. Although NHL is a rare ovarian neoplasm, it is essential to establish an accurate diagnosis as early as possible for therapeutic purposes.

Evidence for pre-zygotic reproductive barrier between the B and Q biotypes of Bemisia tabaci (Hemiptera: Aleyrodidae).

The degree of reproductive isolation between the B and Q biotypes of the whitefly Bemisia tabaci (Hemiptera: Aleyrodidae) is currently not clear. Laboratory experiments have shown that the two biotypes are capable of producing viable F1 hybrids but that these females are sterile as their F2 generation failed to develop, indicating, most likely, a post-zygotic reproductive barrier. Here, we confirm, by molecular and ecological tools, that the B and Q biotypes of Israel are genetically isolated and provide two independent lines of evidence that support the existence of a pre-zygotic reproductive barrier between them. Firstly, monitoring of mating behaviors in homogeneous and heterogeneous couples indicated no copulation events in heterogeneous couples compared to approximately 50% in homogeneous B and Q couples. Secondly, we could not detect the presence of sperm in the spermathecae of females from heterogeneous couples, compared to 50% detection in intra-B biotype crosses and 15% detection in intra-Q biotype crosses. The existence of pre-zygotic reproductive barriers in Israeli B and Q colonies may indicate a reinforcement process in which mating discrimination is strengthened between sympatric taxa that were formerly allopatric, to avoid maladaptive hybridization. As the two biotypes continued to perform all courtship stages prior to copulation, we also conducted mixed cultures experiments in order to test the reproductive consequences of inter-biotype courtship attempts. In mixed cultures, a significant reduction in female fecundity was observed for the Q biotype but not for the B biotype, suggesting an asymmetric reproductive interference effect in favour of the B biotype. The long-term outcome of this effect is yet to be determined since additional environmental forces may reduce the probability of demographic displacement of one biotype by the other in overlapping niches.

Comparative study of tissue adhesive therapy versus band ligation in control of actively bleeding esophageal varices.

BACKGROUND AND STUDY AIMS: Bleeding esophageal varices is a common life-threatening emergency that carries a significant morbidity and mortality. Acute variceal bleeding is considered active when spurting and/or oozing varix is seen at the time of endoscopy, or inactive in the presence of large esophageal varices with blood in the stomach with no other bleeding source at the time of endoscopy. Aim: comparing endoscopic variceal ligation (EVL) versus cyanoacrylate injection (CI) in active esophageal variceal bleeding control. PATIENTS AND METHODS: a retrospective single tertiary center study from April 2014 to February 2018, including 401 patients with active esophageal variceal bleeding. RESULTS: Endoscopic hemostasis was achieved by both endoscopic variceal ligation in 182 patients (91.9%) and cyanoacrylate injection in 197 patients (97.05%) without significant difference (P value 0. 15). Re-bleeding occurred more frequently in EVL group 20 patients (10.1%) compared to 14 patients (6.9%) in CI (P value 0.01). Early six-week Mortality was higher among EVL group (20.7%) compared to CI (17.2%) without statistical significance (P value 0.3). CONCLUSION: Both EVL and CI are almost as effective in achieving endoscopic hemostasis. CI is more effective, feasible, and could be used as a salvage therapy and/or spared for risky active bleeding esophageal varices.

Specific genes from the potato brown rot strains of Ralstonia solanacearum and their potential use for strain detection.

Ralstonia solanacearum is the agent of bacterial wilt infecting >200 different plant species covering >50 botanical families. The genus R. solanacearum can be classified into four phylotypes and each phylotype can be further subdivided into sequevars. The potato brown rot strains of R. solanacearum from phylotype IIB, sequevar 1 (IIB1), historically known as race 3, biovar 2 strains, are responsible for important economic losses to the potato industry and threaten ornamental crop production worldwide. Sensitive and specific detection methods are required to control this pathogen. This article provides a list of 70 genes and 15 intergenes specific to the potato brown rot strains of R. solanacearum from phylotype IIB1. This list was identified by comparative genomic hybridization on microarray and subsequent polymerase chain reaction validation with 14 IIB1 strains against 45 non-IIB1 strains that covered the known genetic diversity in R. solanacearum. The microarray used consisted of the previously described microarray representative of the phylotype I strain GMI1000, to which were added 660 70-mer oligonucleotides representative of new genomic islands detected in the phylotype IIB1 strain IPO1609. The brown rot strain-specific genes thus identified were organized in nine clusters covering 2 to 29 genes within the IPO1609 genome and 6 genes isolated along the genome. Of these specific genes, 29 were parts of mobile genetic elements. Considering the known instability of the R. solanacearum genome, we believe that multiple probes are required to consistently detect all IIB1 strains and we recommend the use of probes which are not part of genetic mobile elements.

Acute coronary syndrome remodels the antiplatelet aggregation properties of HDL particle subclasses.

Essentials HDL subclasses were studied in acute coronary syndrome (ACS). HDL2 from ACS patients have better antiplatelet potency than HDL from non ACS subjects. ACS remodels the antiplatelet properties of HDL subclasses. Oxidized polyunsaturated fatty acids content of HDL is modified by ACS. SUMMARY: Background Although HDLs have antithrombotic effects by reducing platelet activation, the relationship between HDL levels and the risk of acute coronary syndrome (ACS) is unclear, as HDL particles are heterogeneous in composition and biological properties. Objective To characterize the effects of HDL2 and HDL3 subclasses from ACS patients and non-coronary artery disease (CAD) subjects on platelet activation. Methods We measured platelet aggregation and ex vivo thrombus formation, analyzed signaling pathways by flow cytometry, and performed a targeted lipidomics analysis on HDL subclasses. Results Analysis of human platelet aggregation in suspension, adhesion on von Willebrand factor and thrombus formation on collagen under arterial shear demonstrated that HDL2 from ACS patients had higher antiplatelet potency than HDL3 from ACS patients and HDL from non-CAD subjects. HDL binding to scavenger receptor class B type I was essential for this effect. A lipidomics analysis revealed that HDL2 from ACS patients had more oxidized polyunsaturated fatty acids (PUFAs). An inverse correlation between the concentrations of 9-hydroxyoctadecadienoic acid (9-HODE), 13-hydroxyoctadecadienoic acid (13-HODE), the eicosapentaenoic acid metabolite 18-hydroxyeicosapentaenoic acid (18-HEPE) and hydroxyeicosatetraenoic acid isomers in HDL2 and platelet aggregation was observed. This relationship was further demonstrated by the direct inhibitory effects of 18-HEPE, 9-HODE, 13-HODE, 17-hydroxydocosahexaenoic acid and 14-hydroxydocosahexaenoic acid on collagen-related peptide-induced platelet aggregation, indicating that oxidized PUFAs contribute to the antithrombotic effect of ACS HDL2. Conclusions Our data shed new light on the antiplatelet effects of HDL subclasses, and suggest physiological adaptation through the modulation of HDL properties in ACS patients that may limit their platelet-dependent thrombotic risk.

Therapeutic Hypothermia in Asphyxiated Neonates: Experience from Neonatal Intensive Care Unit of University Hospital of Marrakech.

INTRODUCTION: Therapeutic hypothermia (TH) is now recommended for the treatment neonates with hypoxic-ischemic encephalopathy (HIE). This treatment protocol is applied in our department since June 2012. The aim of this study is to report the first experience with head cooling in asphyxiated neonates in Morocco. PATIENTS AND METHODS: Prospective study of newborns admitted for HIE from July 18, 2012, to May 15, 2014, in Neonatal Intensive Care Unit (NICU) of Mohamed VI University Hospital. The results were studied by comparing a newborn group who received hypothermia to a control group. RESULTS: Seventy-two cases of neonates with perinatal asphyxia were admitted in the unit. According to inclusion criteria thirty-eight cases were eligible for the study. Only 19 cases have received the hypothermia protocol for different reason; the arrival beyond six hours of life was the main cause accounting for 41%. Complications of asphyxia were comparable in both groups with greater pulmonary hypertension recorded in the control group. The long-term follow-up of protocol group was normal in almost half of cases. CONCLUSION: Our first experience with the controlled TH supports its beneficial effect in newborns with HIE. This treatment must be available in all the centers involved in the neonatal care in Morocco.

High frequency of chromosome 9p allelic loss and CDKN2 tumor suppressor gene alterations in squamous cell carcinoma of the bladder.

BACKGROUND: In the Western Hemisphere, 90% of bladder cancers are transitional cell carcinomas, while only 7% are classified as squamous cell carcinomas. In contrast, in Egypt and regions of the Middle East and Africa, where infection by the trematode Schistosoma haematobium is endemic, squamous cell carcinoma is the most common bladder cancer as well as the most common cancer in men. PURPOSE: We planned experiments to understand the genetic defects underlying the development of squamous cell carcinoma and to determine if the morphologically and clinically distinct squamous cell carcinoma and transitional cell carcinoma of the bladder evolve following different genetic alterations. METHODS: Squamous cell carcinoma specimens from high-risk (Egypt, n = 19) and low-risk (Sweden, n = 12) populations were examined for genetic defects known to be involved in transitional cell carcinoma tumorigenesis. Homozygous deletions of the CDKN2 tumor suppressor gene were detected by comparative multiplex polymerase chain reaction. Mutations in the CDKN2 and p53 (also known as TP53) genes were analyzed by single-strand conformation polymorphism and DNA sequencing. Immunohistochemical staining of p53 protein was also performed. Allelic losses in chromosome arms 9p, 9q, and 17p were determined by microsatellite analysis. RESULTS: Homozygous deletions and sequence mutations in the CDKN2 gene were found in 67% (eight of 12) of squamous cell carcinoma specimens, a frequency three times higher than that reported for uncultured transitional cell carcinomas (P = .009). Hemizygous and homozygous deletions in 9p, where CDKN2 resides, were found in 92% (11 of 12) of uncultured squamous cell carcinomas, while only about 39% (35 of 90) of transitional cell carcinomas showed these losses (P = .001). Deletions in 9p with no change in 9q were found in 92% (10 of 11) of squamous cell carcinomas compared with only 10% (11 of 110) of transitional cell carcinomas (P < .001) reported in the literature. The frequency of p53 mutations in squamous cell carcinomas was similar to that reported for invasive transitional cell carcinomas (60%), but the type and position of mutations differed between the two tumor types. Allelic losses in chromosome arm 17p, where the p53 gene resides, were found to be less frequent in squamous cell carcinomas (38%) than in invasive transitional cell carcinomas (60%). CONCLUSIONS: Our results suggest that a putative tumor suppressor gene on 9p, possibly CDKN2, may contribute to squamous cell carcinoma tumorigenesis. Our data on squamous cell carcinoma and previously reported data on transitional cell carcinoma indicate that these two bladder carcinomas differ in their genetic alterations, suggesting that distinct underlying genetic defects may explain, at least in part, the pathological differences between the two tumors of the bladder epithelium. IMPLICATIONS: Development of diagnostic and therapeutic strategies for squamous cell carcinoma of the bladder based on its distinct genetic alterations is warranted.

[Percutaneous closure of three septal defects by two Amplatz occluders implanted during the same procedure]. / Fermeture percutanée de 3 communications interauriculaires par 2 dispositifs d'Amplatz implantés au cours d'un même cathétérisme.

Multiple atrial septal defects can be closed by interventional catheterisation. The procedure requires an accurate morphological evaluation: number of defects, distance from their edges to the main cardiac structures, resistance of the septum. The authors report the case of a 63 year old woman presenting with cardiac failure in whom 3 atrial septal defects were diagnosed. All 3 defects were successfully closed by the implantation of two Amplatz devices. Control echocardiography at 6 months showed the occluders in a normal position with no residual shunt and the patient was asymptomatic.

[Myocardial infarction in a young female smoker taking oral contraception]. / Infarctus du myocarde chez une jeune femme fumeuse sous contraception orale.

A 33 year old woman suffered a lateral myocardial infarction for the first time, and was treated by pre-hospital thrombolysis and secondary angioplasty on the diagonal artery. Fifteen days before the cardiac event she had undergone a left ovarian cyst excision and left salpingectomy for an ectopic pregnancy. She was a moderate smoker and had been taking a second-generation biphasic minidose oral contraceptive (ethinyl-estradiol 30-40mg and levonorgestrel 150-200 mg) for about ten years. Fifteen days before the myocardial infarction and due to the ectopic pregnancy she had changed to a combined monophasic minidose oral contraceptive pill containing ethinylestradiol (30 mg) and drospirenone (3 mg). The eventual outcome was favourable, with no complications. In this article we discuss the possible implications of the various factors (oral contraceptive, tobacco use, and surgical intervention) in this young woman with a myocardial infarction.

Intramyocardial transplantation of mesenchymal stromal cells for chronic myocardial ischemia and impaired left ventricular function: Results of the MESAMI 1 pilot trial.

BACKGROUND: The MESAMI 1 trial was a bicentric pilot study designed to test the feasibility and safety of intramyocardially injected autologous bone marrow-derived mesenchymal stromal cells (MSCs) for the treatment of ischemic cardiomyopathy. METHODS AND RESULTS: The study included 10 patients with chronic myocardial ischemia, left ventricular (LV) ejection fractions (EFs) of ≤35%, and reversible perfusion defects who were on stable optimal medical therapy and were not candidates for revascularization. MSCs (mean: 61.5×10(6) cells per patient) were injected into 10-16 viable sites at the border of the LV scar via a NOGA-guided catheter. Both primary endpoints, feasibility (successful harvest, expansion, and injection of autologous MSCs) and safety (absence of severe adverse events [SAEs]) were met in all 10 patients at the 1-month follow-up time point, and none of the SAEs reported during the full 2-year follow-up period were attributable to the study intervention. The results of secondary efficacy endpoint analyses identified significant improvements from baseline to Month 12 in LVEF (29.4±2.0% versus 35.7±2.5%; p=0.003), LV end-systolic volume (167.8±18.8mL versus 156.1±28.6mL; p=0.04), 6-min walk test and NYHA functional class. CONCLUSIONS: Our results suggest that autologous MSCs can be safely administered to the hearts of patients with severe, chronic, reversible myocardial ischemia and impaired cardiac function and may be associated with improvements in cardiac performance, LV remodeling, and patient functional status. A randomized, double blind, multicenter, placebo-controlled clinical trial (MESAMI 2) will evaluate the efficacy of this treatment approach in a larger patient population. CLINICAL TRIAL REGISTRATION: Unique identifier: NCT01076920.

Constitutive caspase-like machinery executes programmed cell death in plant cells.

The morphological features of programmed cell death (PCD) and the molecular machinery involved in the death program in animal cells have been intensively studied. In plants, cell death has been widely observed in predictable patterns throughout differentiation processes and in defense responses. Several lines of evidence argue that plant PCD shares some characteristic features with animal PCD. However, the molecular components of the plant PCD machinery remain obscure. We have shown that plant cells undergo PCD by constitutively expressed molecular machinery upon induction with the fungal elicitor EIX or by staurosporine in the presence of cycloheximide. The permeable peptide caspase inhibitors, zVAD-fmk and zBocD-fmk, blocked PCD induced by EIX or staurosporine. Using labeled VAD-fmk, active caspase-like proteases were detected within intact cells and in cell extracts of the PCD-induced cells. These findings suggest that caspase-like proteases are responsible for the execution of PCD in plant cells.

[Morphological and functional characteristics of the culprit coronary artery in acute coronary syndrome]. / Aspects morphologiques et fonctionnels de l'artère coronaire coupable d'un syndrome coronaire aigu.

In the catheter laboratory, faced with a patient with unstable angina, the problem is not the diagnosis of epicardial coronary artery stenosis but rather the atherothrombotic complexity of the stenosis and the identification of other less stenotic lesions on angiographically normal or nearly normal segments. The authors describe two appearances with morphological analysis of the vulnerable or unstable plaque and functional analysis of coronary artery vasomotricity. Acute coronary syndromes due to a clearly stenotic atherothrombotic plaque on angiography pose no diagnostic problems. However, an acute coronary syndrome may be more difficult to assess when angiography shows only simple irregularities of the lumen or no lesions at all. In these cases, angiography is said to be normal and the coronary arteries are considered to be possibly "healthy". Evaluation of the vessels' vasomotricity is especially valuable in this context. Using pharmacological stress tests, endovascular ultrasonography is a complementary diagnostic tool which allows identification of the unstable atheromatous process or of a partial atherothrombosis masked by positive remodelling process. These tests may also indicate the optimal treatment.

[Percutaneous embolisation of a iatrogenic fistula between the internal mammary artery and the coronary vein]. / Embolisation percutanée d'une fistule iatrogène entre l'artère mammaire interne et la veine coronaire. Revue de la littérature à propos d'une observation.

Latrogenic fistula between the aorta and coronary vein is a rare complication of coronary bypass surgery due to accidental venous or arterial graft onto a coronary vein. The authors report a case of a patient admitted to hospital 2 months after coronary bypass surgery for cardiac failure due to a iatrogenic fistula by implantation of the left internal mammary artery on the great coronary vein. This presentation led to the choice of percutaneous embolisation of the fistula by the release of 6 coils. Based on a review of the literature, this clinical case illustrates the feasibility and value of percutaneous embolisation of iatrogenic fistulae.

[Coronary-bronchial artery fistula and two-vessel coronary disease treated by embolisation of the anastomosis and coronary angioplasty]. / Fistule coronaro-bronchique et lesions coronaires bitronculaires, traitées par embolisation de l'anastomose puis par angioplastie coronaire.

Coronary-bronchial artery fistulae are rare and may present with broncho-pulmonary haemorrhage and myocardial ischaemia. The authors report the case of a coronary-bronchial artery fistula associated with bronchiectasis responsible for haemoptysis and discovered at coronary angiography performed during an acute coronary syndrome. Radical treatment by embolisation of this fistula allowed the use of platelet inhibitors and anticoagulants for the coronary angioplasty performed secondarily. This method is an interesting alternative to surgical ligature.
